Folks,
I'm in great need of a 432 MHz transverter (actually if the transmitter
doesn't work, that's OK).
I'm in the SE Mich area, and can meet someone to pick it up.
This is work-related, and I need it for a road trip that is currently

Another commonly used ground is the water system. Check your water

grounding wire from the service entrance connects to the cold water
system.

Hello Jim,
I use a very coarse sand paper to remove the paint. In K2, Elecraft did mask
off some of the contact areas. I just don't know why they don't do that on
W2. I suppose the cost to do that should be minimal to Elecraft.
cheers,

Computer control can really add to the enjoyment to using a K3. I

I've been using computer control with my radios for years. The newest

capabilities of the K3.

It is best not to rely on water pipes for any type of grounding.
Many homes have various combinations of steel, copper, plastic, etc. piping.
These are electrically discontinuous, often with purposefully inserted
