The K3's IF OUT bandwidth is limited only by the front-end RF filters so
it covers an entire amateur band, plus. That is handy for a panadapter
because it is always centered on the VFO A frequency. The IF center

Greetings all,
We had an interesting time a few years ago in the UK when PLT (power
line telecomms) was a new threat. We built a mains supply to spec

Hi David,
My suggestion is a coaxial trap or possibly a series LC to deck (use
a trimmer C). The insertion loss will be minimal. A single trap had
little effect on the feed Z as shown on my Tx but ideally a second
one about lambda/4 at 145MHz further down the feeder will offset the
effect at
Hi all,
The UK amateurs voted by a reasonable but no a large majority to drop
the code post WRC03.
The issue for the administration (then the Radiocommunications Agency
- RA) was a defensible licensing need. Historically CW was the only
common mode between amateurs and the other users with whom

I have a couple of drums of mains cable known in the UK as 2.5 TE,
the 2 conductors are 2.5 mm sq and earth is about 1.5. The inner end
is available so I soldered the two main
Hi All,
Reading the magnetic field and phase noise saga makes me think of

another room cures it.
How about using mains isolation transformers so only connection
