The HF-250 is the successor to the HF-225. It
adds features that HF-150 and HF-250 owners were asking for: back-lit
display, frequency readout to 100 Hz, 255 memory channels, more
functionality in computer control, two clock timers, and tape recording
switching output. In December 1996, an improved high-end version was
released called the HF-250E, the "E" standing for Europa.
Options include an infra-red keypad (rather like
a television remote control) and the DU250 detector board (that adds AM
synchronous detection with a selectable sideband and FM). For portable
operation, the option of a WA250 active whip antenna with a
internally-mounted preamplifier is available.
Standard filters include 10, 7 and 4 kHz for AM,
2.2 kHz for SSB and 200 Hz for CW. The FM bandwidth with the DU250
option is 12 kHz. The user can change the default bandwidth for each

Lowe Electronics of Matlock Derbyshire in the UK
has a firm reputation in Europe and North America for quality shortwave
receivers. Lowe Electronics have been selling shortwave receivers from
decades. The move into the production area came in 1987 as a result of
an absence of entry-level table-top shortwave listener sets in the UK
marketplace (the Trio Kenwood R-600 had been discontinued). Early Lowe
designs, such as the HF-125, looked as though they had been home-built
on a kitchen table (the first ones apparently were), but the company
very quickly shaped the outside casing into a unique "British" look.
same (freelance) designer has worked on the AOR AR7030, which explains
the similar look.
The Lowe HF-250 first appeared in the UK in late
September 1995 and has since found its way into Europe and North
America. The black-coloured case is made of heavy-duty extruded
aluminium and is of sufficient thickness to make it a very rugged
receiver, suitable for DXpeditions. The bottom plate, however,
containing the four supporting feet is thinner. We began our tests
a production model with serial number 453902 that is marked on the
bottom of the set. The two front feet can be clipped forward so that
receiver is tilted towards the user. We found this to be the most
comfortable way to use the receiver.
The receiver is compact, just 28 by 10 by 20
centimetres and weighing in at just over 2.5 kilos. The 12V DC power
supply is included in the price. It either works on 120 or 240 volts AC
depending on where you buy the set, i.e. it is not dual voltage. The
receiver comes with a floppy diskette (MS-DOS format) which allows you
to drive most functions from a personal computer. There's an RS-232
on the back of the set which requires a suitable cable. Other companies
have produced more sophisticated computer programs which drive the
The Lowe HF-250 is a dual-conversion
super-heterodyne receiver with a first IF frequency at 45 MHz and a
second IF (where the selectivity is determined) at 455 kHz. Lowe has
used many proven techniques from the HF-225 and HF-150 so, from a
technical point of view, the HF-250 is not a completely new receiver.
the back of the set is a sliding switch which allows you to select one
of three antenna inputs. Apart from the standard 50 ohm input there is
600 ohm unbalanced input designed for wire antennas. In the "whip
antenna" position a small amplifier with high input impedance is
switched in. Only use this position with a whip antenna, because the
amplifier is very easily overloaded.
Directly after the input, a relay-switched 20 dB
attenuator is incorporated. We felt that, for a receiver of this class,
a 3-position attenuator with steps of 10, 20 and 30 dB should be
offered. Personally, we believe the extra cost could be recovered from
offering the whip-antenna as an option. The HF-250 uses the same mixer
configuration as the Lowe HF-150: two Plessey SL 6440 high level active
mixers, separated by a 15 kHz roofing filter. In the HF-250 however, 2
crystal filters are used instead of just one in the HF 150. This
protects the 2nd mixer better against overloading. The greatest
difference between the HF-250 and the HF-150 is that the latter has
one 30 MHz low-pass filter in front of the 1st mixer. Therefore all
signals between 30 kHz and 30 MHz are fed to the first mixer, which can
easily led to overloading and intermodulation.
With the HF-250 on the other hand, after the 30
MHz low-pass filter, six automatically switched filters are used before
the first mixer. For longwave, there is a low-pass filter which rejects
all signals above 500 kHz, the other bandpass filters are for: 0.5 to
1.7 MHz, 1.7 to 4.2 MHz, 4.2 to 11 MHz, 11 to 19 MHz and 19 to 30 MHz,
preceded by a 1.7 MHz high-pass filter. Although the filters have more
bandwidth than an octave, this gives a great improvement with respect
overloading effects and second order intermodulation from strong
transmitters on other frequency bands.
For the IF selectivity Lowe uses the same high
quality multipole ceramic filters as found in the HF-225 and HF-150,
configured around a Plessey SL 6700 multi-function IF IC. The filters
are partly switched in cascade. The 2.2 kHz filter is followed by the 4
kHz and 10 kHz filter. The 7 kHz filter or the 4 kHz filter is followed
by the 10 kHz filter. In the 10 kHz bandwidth position only the 10 kHz
filter is used.
As the other filters are by-passed and the IF
stages between the filters are still in use, we recommend the use of
10 kHz bandwidth only for high audio quality reception of strong
transmitters. For CW reception the 2.2 kHz filter chain is used, but a
200 Hz bandpass filter with a centre frequency of 800 Hz is switched
into the audio circuit. This gives audible reduction of adjacent CW
transmitters. But it doesn't overcome the problem that while listening
to a weak CW station, the sensitivity of the receiver can be reduced by
a strong CW station which lies within the 2.2 kHz bandpass of the IF
filter. For that reason, it would be useful if you could switch off the
AGC, and/or adjust the gain manually. This would also help if you
to use one of the modern DSP audio filters /noise reduction units in
combination with the HF-250. The HF-250 is equipped with a
in the audio circuit, which is permanently switched in. It responds
mainly to pulse-type interference, such as ignition noise and other
sparks. Overall, the Lowe HF-250 is a well designed receiver for the
European price, using and improving on concepts tried and tested in
In general the Lowe receivers have an economy of
buttons on the front panel. The HF-250 is no exception. That means that
most buttons have a dual function and you need to spend a few hours
getting the hang of some functions (like setting the timers or changing
If you connect the power supply, the radio
springs to life momentarily to show the software version on the 6 digit
orange-coloured LED display. The back lighting then goes off as the
radio goes into stand-by mode, showing the time (including seconds).
When the radio is switched on this same display is used for frequency
readout (to the nearest 100 Hz, an improvement over earlier models like
the HF-150). The display actually shows the frequency of the carrier in
The HF-250 comes with a number of optional
extras. We would strongly recommend getting the infra-red remote
(which Lowe call the RC-250 commander). It allows you to tap in desired
frequencies directly (e.g. 6-1-6-5 immediately sets the receiver to
kHz). Below 3000 kHz the receiver expects you to press the ENTER key
after tapping in the desired channel. Without the keypad, you have to
use the UP-DOWN buttons and the large rotary tuning knob on the
receiver's front panel. We asked a couple of people to play with the
for a few hours. Each reported that they ended up using a combination
the remote control and the knobs on the front panel.
The HF-250 will store up to 255 favourite
frequencies, remembering the mode as well. Lowe says the receiver will
remember the channels for around 10 years! Use of the memory functions
is straight forward.
The HF-250 has a frequency range of 30 kHz to 30
MHz, whereby the range from 30 to 60 kHz is not specified. Tuning steps
are 8 Hz for SSB, AM synchronous (if added) and CW, 50 Hz for AM and
Hz for FM. Buttons for 1 MHz steps up and down are provided for larger
frequency changes. There is a FAST button on the front panel to allow
you to move across the dial much faster 10 kHz steps. You have to keep
this button depressed with your thumb while turning the tuning knob
your the rest of the fingers on the your right hand. The tuning rate of
the HF-250 changes as you spin the tuning knob faster, so the fast
button is not often required. We found it handy that the tuning knob
be also used to step through the 255 memories of the HF-250, which can
store frequency and as well as mode.
The remote control unit is great for jumping in
huge steps from one part of the dial to another (e.g. 15 MHz to
in one go). But the up-down buttons on the remote control have only one
speed...VERY SLOW. Press the UP button with the set tuned to 6000 kHz.
One minute later the receiver has reached 6015 kHz! You can MUTE the
with the remote control, but you cannot adjust the volume or tone
from your armchair as you can on most TV remotes.
The supplied English-language instructions on
programming the clock and timers are very confusing and, in our view,
could do with a complete re-write. It isn't helped by the non-standard
layout of the keys. This takes some getting used to, but may well be
quite handy for unattended recording, when you get used to it.
The standard HF-250 receives AM, Lower Sideband
(LSB), Upper Sideband (USB), and Morse code CW. Optional boards can be
installed for Narrow Band FM (NBFM) and synchronous AM (which offers
optional selection of the sidebands - an improvement on some earlier
To change the receiving mode you first press a
mode button, the current mode light starts flashing, and then by
pressing the UP-DOWN keys you can sequence through the options. Once
selected, you have to press the mode switch again to stop the LED
blinking and return to normal tuning.
The tone control is quite effective, although on
a receiver of this type may be some form of band-pass filter or notch
filter would have made more practical use of the space available.
We measured the AM sensitivity of the receiver
with a signal which was modulated with a 1 kHz signal to 60% modulation
depth, equal to all other tests we've done in past years. Most
transmitters currently modulate an average of 60%, even though the
is higher with the introduction of HF-Optimod at transmitter sites.
Therefore, our tests give slightly lower sensitivity figures than Lowe
specifies with 70% modulation depth. But sensitivity on shortwave is
the most important specification. All signal levels are in microVolts
across 50 ohms, required for 10 dB S+N/N.
We found a sensitivity of 1.5 to 2 µVolts
in the 60 kHz to 1.7 MHz range, much better than required for weak
signal reception in this frequency range. Under 60 kHz, (the receiver
can be tuned down to 30 kHz) the sensitivity is lower due to
noise, but with a good antenna reception of data transmitters in this
range is possible.
Above 1.7 MHz the sensitivity changes from 0.76
to 1.4 µvolts, due to the ripple and differences in loss of the
bandpass filters at the input. On 29.5 MHz the sensitivity of our
production sample was 1.08 µVolt. The sensitivity remains nearly
constant regardless of whether the 4, 7 or 10 kHz bandwidth was chosen.
This is an indication that sensitivity is mainly determined by the
For SSB sensitivity we used an unmodulated
signal, detuned to a 1 kHz tone. For a 12 dB sinad signal/noise ratio
sensitivity figures over the 1.7 to 30 MHz lies between 0.18 to 0.27
µV. Again, these figures are good and more than sufficient. The
noise floor with the 2.2 kHz bandwidth lies at - 128 dBm (0.09
µV), equalling a noise figure of 12 dB for the receiver in the
range 1.7 to 30 MHz. This is a very good figure.
Signal to noise ratio
Sensitivity figures give the signal required for
10 S+N/N. (signal + noise, divided by noise). At this point this signal
is just intelligible. If you want to easily follow a broadcast, at
20 dB signal to noise ratio is required. The modulation sounds clear
noise free at 30 dB or more S+N/N. We measured how much antenna signal
was required to achieve a better intelligibility than with 10 dB S+N/N.
With a signal of 3.1 µVolts 20 dB was achieved, for 30 dB S+N/N
9.65 µV was required in the AM mode with the 7 kHz filter. These
are unweighted figures, i.e. measured over the full audio range.
Measured in quasi-peak mode with a CCITT P 53A telephone filter, which
gives strong attenuation under 300 Hz and above 3400 Hz, the S+N/N
values improve approx. 4 dB. These are good figures.
We were impressed with the action of the
automatic gain control (AGC). The AGC should keep the audio at a
constant level, regardless the strength of the received signals. With
many low-cost receivers, the audio level drops considerably at low
signal strength. This is a nuisance, because if you receive a weak
station which is hard to understand, the volume drops, making the
even more difficult to understand. You can increase the volume, but you
have to reach for the control again if you start band scanning. Not so
with the HF-250. The output was adjusted to 0 dB with an RF input
of 1 milliVolts, 60% AM modulated with a 1 kHz tone. Then the level of
the input signal was reduced. The audio volume was just a 0.5 dB
(barely noticeable) with an input signal of 0.5 µVolts. This
a S+N/N of 6 dB, at which speech is not longer intelligible. This means
that the AGC of the HF-250 keeps the audio level really at a constant
level until the signal is lost in the noise. This is one of the best
actions we ever measured.
The HF-250 has a loudspeaker built into the
cabinet. The speaker is mounted in a cleverly designed slot in the top,
which also doubles as a carrying grip. This way of mounting gives a
reduction in bass response and very high frequencies (hiss and noise).
The HF-250 sounds very pleasant on music as well as speech. If you
connect an external speaker to the HF 250 for long distance listening,
use a communications speaker with a restricted frequency range. The
audio range of the HF-250 is flat down to 40 Hz, even in the mid-
position of the tone control. In the treble setting, the tone control
rolls off the bass response below 300 Hz. Some shortwave listeners like
this "hi-fi" approach, which is fine on stronger signals. Others may
find the bass response a bit too much. It is a matter of personal taste.
With a 60% modulated AM signal (tone 1 kHz) and
the 7 kHz bandwidth filter, the external speaker output delivered 2
into a 5 Ohm speaker before the audio distortion rises to 10%. At
standard 100 mW output level, total harmonic distortion was less than
1%, but very exact tuning to obtain minimum distortion is required. The
maximum signal to noise ratio, measured wideband over the audio output
was 48 dB with a RF input signal of 5 milliVolts.
We measured with a spectrum analyser the audio
response of the HF-250 with the different filters. This gives an
excellent indication of the combination of IF selectivity and audio
response in AM. It is certainly of help, but in crowded CW bands the
tone generated by the transmitters sometimes differ by not more than a
few hundred Hz, and for these small tone differences the filter does
give much attenuation.
The HF-250 is equipped with a record output for
the connection of a tape recorder that gives a constant output level of
320 mV at 60% modulation depth. For connection of the headphone in the
front-panel jack a very sensitive type with 8 ohms impedance is
required, as the headphone is fed via 220 ohms serial resistors. You
also use a modern 32 ohms types communications type. These usually have
a lower bass response too.
The set has an analogue S-meter, but in contrast
to the large and prominent LCD display, the lettering on the S-meter is
very small. It is difficult to read the calibration marks from 1 S
to S-9 + 60 dB. The meter is lit from the top, but it looks rather in
the "budget" class compared with Japanese competition.
However, on low- and medium-cost receivers, the
S-meter mostly is just an indicator. Not so with the HF-250. Despite
very small dimensions, the S-meter is very well calibrated above S3 and
shows a good logarithmic response over the whole range. This is shown
figure 4. The straight line is the reading of a perfect S-meter, but
can see that the reading of the Lowe HF-250 S-meter is very good.
AM Synchronous Detection
With the optional board installed, the Lowe
HF-250 allows you to reduce the effects of some types of fading. Most
annoying is the fact that you have to change the mode back to AM to
start band-scanning again or the receiver just howls as you move in
between channels. The earlier Lowe receivers were much cleverer in this
We tested an off-the-shelf production sample
with the optional synchronous detector already built-in. During
listening tests we found that on weak signals with fading, the
synchronous detector dropped out of lock and that precise tuning, exact
on the carrier was required. Our measurements revealed that the
synchronous detector didn't match the specifications mentioned in the
manufacturers handbook. The distortion level was too high, a very
signal was required before the lock indicator lit-up and we had to
retune the receiver 200 Hz when switching over from USB to LSB to keep
it in lock.
Unsure as to whether the problem might be a
fault on this particular receiver, we asked Lowe to send us a
new second receiver, because we had some problems with the dynamic
selectivity of the first receiver too. Thanks to quick reaction of Lowe
Europe, a new receiver was delivered the same day. Unfortunately we
discovered that the synchronous detector of the second receiver was
not working properly. It was better than the first one, and the
kept locked even on low signal strengths, but now there was noticeable
level differences between upper and lower sideband and the distortion
was in the order of 10%. As we know that Lowe can make a good working
synchronous detector we were surprised at these problems which we trace
to alignment errors and quality control.
We measured the dynamic range and intercept
point according to the CCIR recommendations for SSB marine receivers.
This test uses two signals, 30 kHz apart. We tuned the Hewlett Packard
8662 A signal generators (less than - 147 dB sideband phase noise at 10
kHz from the carrier) to 10530 and 10560 kHz. Both signal generators
were very well decoupled via 6 dB pads and a Wiltron combiner. The
combined signal was fed via a Rohde and Schwarz DPSP precision step
attenuator to the receiver, tuned first to 10500, later to 10590 kHz,
which 3rd order intermodulation products appear.
With the 2.2 kHz filter, we have to raise the
level of the signals to 2 x -37 dBm, to obtain an intermodulation
product equal to the noise floor of - 128 dBm. The difference of the
signal level and the noise floor is 91 dB. This is the
intermodulation-free dynamic range of the HF-250. Also the third order
intercept point is now determined: (91/2) + (-37 dBm) = + 8.5 dBm. For
the price class of this receiver in Europe these are certainly very
figures, although not sufficient to use the HF-250 with a very large
antenna without the use of an attenuator. That is the reason why we'd
like to see a multistep attenuator instead of the single 20 dB position.
A signal of - 37 dBm equals 3.16 mVolts. This is
indicated on the Lowe S- meter as S9 + 30 dB. If two or more signals
higher in level than S9 + 30 dB fall within the passband of one of the
RF input filters (so they are together fed to the first mixer), 3rd
order intermodulation products can disturb reception of very weak
There are two kinds of selectivity. The static
selectivity is the attenuation curve of the IF filters. Lowe uses good
quality multi-pole IF filters. The 2.2 kHz SSB filter has a - 6 dB
bandwidth of 2.3 kHz and the bandwidth at 60 dB (1000 times)
is just 3.4 kHz. For the 4 kHz filter these values are: 5.9 and 9.8
for the 7 kHz filter 8.8 and 12.9 and for the 10 kHz filter they are
10.5 and 21.5 kHz. These are nice values, and the bandwidth remains
tight up to 80 dB attenuation. But this is not the whole story. In
practice, these static selectivity curves are not as good in any
receiver. There is always some signal leakage around the filter,
caused by the printed circuit board or leakage via the power supply
connections in the amplifier stages in between the filters.
The main problem however is noise generated by
the main-oscillator, the synthesiser. In short: if the noise level of
the synthesiser is too high, this noise is mixed back into the passband
of the IF filter. This is called reciprocal mixing. The result is that
high attenuation of unwanted signals is no longer achieved.
The CCIR measuring protocol for marine shortwave
receivers gives rules for the measurement of the dynamic selectivity,
also called RF protection ratio. This measurement protocol gives
selectivity values in which all the effects of synthesiser noise and
leakage are incorporated. So, dynamic selectivity gives a real
impression of the selectivity in practical use.
All the receivers tested by Radio Netherlands in
the past years are measured for dynamic selectivity. For the
measurement, the receiver is tuned to the signal of a low- sideband
noise signal generator, AM modulated, 60% modulation depth with a 1 kHz
tone. The level of this signal is adjusted, until the receiver gives 20
dB S+N/N, which is an easily intelligible signal. This is called the
wanted signal. For the HF-250 this level was 3.1 µVolts. At the
same time, the signal of a second generator, also modulated with a 1
tone with 60% modulation depth, is fed to the receiver. Both signal
generators are properly decoupled, so they do not influence each other.
The second generator is first tuned to a higher frequency, in steps of
0.1 kHz up to 30 kHz away from the frequency tuned in on the HF-250.
Later the second generator is tuned to lower frequencies. It is clear,
that as soon as the signal of the second generator falls outside the
passband of the chosen filter in the receiver, the signal of the
"interference" generator can be higher than that of the wanted signal.
The level of the interfering signal is then raised, until the signal to
noise ratio of the wanted signal drops to 14 dB. This is an
signal, but slightly disturbed by the unwanted signal.
This is a good practical test. The receiver is
tuned to an easily intelligible signal. For the HF-250 this is approx.
S3 signal. The dynamic selectivity now gives (in dB's) how much
an interfering signal must be before a wanted signal suffers slight
disturbance. This situation can be found all over the broadcasting
Our first production sample of the HF-250 had a
level of synthesiser noise which was far too high, with as result that
selectivity was bad. The second example of the receiver which we
purchased didn't have this problem and we measured a synthesiser noise
of - 128 dB/Hz at a distance of 20 kHz. This is a good value for a
receiver in this price class. In the dynamic selectivity curve you can
see that just next to the passband of the chosen filter in the
the signal can be up to approx. 65 dB (1780 x) stronger. In fact it is
the attenuation curve of the filter. But on larger frequency distances
the attenuation curve flattens and the level of the unwanted signals
cannot rise much more. This deterioration of the attenuation curve of
the filter in the receiver is caused by sideband noise, filter leakage
and overloading. Compared to other receivers is this European price
class, the dynamic selectivity of the Lowe HF-250 is good. The AOR
AR7030, however, has a better figure.
If you listen to an easily intelligible signal,
signals of unwanted transmitters higher or lower in frequency cannot be
of unlimited strength. If they become too strong, the receiver cannot
handle them any longer without disturbing the signal of the wanted
station. You'll notice this if you listen to amateur radio stations in
the 7 to 7.1 MHz band, while the antenna delivers at the same time (in
Europe) extremely strong signals of the 41 metre broadcast band (7.1 to
To see what kind of signal level the receiver
can handle before the wanted station is disturbed, we use the same
measurement method as for the dynamic selectivity, but now the unwanted
signals are placed on 100 and 200 kHz above and below the wanted signal
frequency. Independent of the selected filter and mode, we found levels
of 74 dB and 77 dB above the 20 dB S+N/N sensitivity. This equals a
signal level of respectively: 14.7 mV and 20.8 mV. These are very
signals, which appear on the S-meter as roughly S9 + 50 dB readings. In
Europe with large antennas these strong signals are common on long and
medium wave, the 41 and 49 metre band. The overload point is not fixed,
because the AGC circuit is placed in between the first and second
It has to be mentioned that as soon as signal levels rise above 8 mV
+ 40 dB) the HF-250 begins to produce birdies (whistles) and noise on a
number of frequencies around this strong signal. Therefore the use of
the attenuator is required.
Birdies are "ghost" signals such as carriers,
whistles and noises produced by the receiver itself. If the birdie is
strong, weak signal reception on that frequency is not possible and
moderately strong signals can be disturbed. All receivers produce
birdies, but they should be so low in level, that they disappear in the
atmospheric noise when an antenna is connected. For this measurement
antenna input of the receiver is terminated with a 50 ohm dummy-load
the receiver is placed inside a grounded metal cabinet (Faraday cage),
to prevent reception by direct radiation. Then the receiver in USB mode
is slowly tuned from 60 kHz to 30 MHz, during which any birdie
frequencies and their equivalent signal strength is noted.
Here we come to a firm point of criticism. The
second HF-250 receiver was better than the first one, but both
produce hundreds of birdies. Lucky enough, most of them are so low in
level, that they do disappear in the noise when an antenna is
but we found a lot of birdies with a high level, some of them with a
equivalent signal strength of up to S6 on the S- meter. To give you an
idea we note here some of them with the S-meter reading of S2 or
Noted is the frequency which produce a 1 kHz tone in USB, the actual

16318.5 (s3), 16379 (s4), 17278 (s5), 17819 (s2) and so on. We think
that for a receiver in this price class the number of birdies and their
level is much too high, and we think Lowe should do something about it
It seems strange that the squelch level control
is on the back of the receiver! If you mount the receiver in a rack
makes Narrow Band FM mode rather complicated to use!
The Lowe HF-250 is clearly the successor to the
HF-225 Europa and, in most respects, is an improvement on the budget
HF-150 model. There are some tuning quirks which take some getting used
to. The radio has excellent fidelity and it well-suited to shortwave
From a technical point of view we think that the
Lowe HF-250 is a good performer and on some specifications even an
excellent receiver for the price in Europe. We haven't yet tested the
HF-250E, which has better specifications than the HF-250. This nicely
fills the gap between the Lowe HF-150 and the more expensive receivers
such as the Icom R 72 and the Kenwood R 5000. We would like to see less
birdies, and a multi-position attenuator fitted as standard.
In Europe, demand for the receiver has been
good. The standard HF-250 is advertised in most magazines for around
£785 in the UK where is it priced under the Drake R8-series.
is considerable competition from the AOR AR7030 that is priced at
£799 in the UK and, in some respects, has better specifications
for DXing. We advise you to check both sets side-by-side.
In the rest of Europe, the HF-250 offers
good-excellent value. In the USA, however, the exchange rate and import
duty means the basic HF-250 is priced at US$1199, the basic set plus
remote control is US$1249, and with the sync option plus remote the
price is US$1349 which probably means it will only appeal to
Lowe has to re-consider its pricing policy in this region if the new
HF-250 is to break into the North American market alongside other sets
like the Drake R8-series.
A "Europa" version of the HF-250 started
shipping in December 1996. Lowe tells us that the price is same as the
HF250, and the feature set is equivalent to the HF-225E Europa. We have
not yet tested this new model.
