"BT PowerLine Adapters" & other BPL / PLT INTERFERENCE: The
precious radio spectrum from 2 MHz to 330 MHz is under threat from
Power Line Network adapters - PLT / PLA - supplied by, among others,
BT, BT Vision, Comtrend, and Belkin etc. These devices are not
compliant with the
Wireless Telegraphy Act - yet the UK's inept and useless radio spectrum
'regulator' fails to act. Ofcom's incompetence and willful neglect must
be challenged. Please Donate to the Spectrum Defence Fund:

The Bowline I find most useful for fixing end, egg and dog-bone insulators to the ends of the wire and/or ropes. The Round Turn & Two Hitches, Anchor Bend and Buntline Hitch knots are very good for tying a rope to a pole or a mast. 'Animated Knots' will show you how to do them: http://www.animatedknots.com H.F.

It should be noted that the RSGB made some minor syllabus changes in 2009 which were not reflected in the BRATS courses because the author had retired from this duty. This does not make any of the basic information out of date or less useful, it's just that the course material may not quite mesh with the new RSGB syllabus.
