Just to make sure I'm clear on my message... this interface is made
for listening on two radios at the same time from one antenna. But
when one radio transmit, the other in mute by putting it's antenna on
ground and vice-versa.

Hi,
I finally did a first prototype of an interface to link two K2/
KPA100 on one multi-band HF antenna using Don W3FPR schematic. For
my first "from scratch" project, it is not too bad. I first began
to do a PCB. I used two fast SPDT 16A relays from Omron and SO-239
connectors are Amphenol.
I will try it tonight.... But on the bench test, everything was
working fine... Maybe I will need to put a few caps to filter some
RF, I'm not sure.... I will tell you later tonight. This is my
first prototype version... My « main goal » is to have a interface
like this one, but also one mic and one paddle for 2 radios.
Unfortunatly, I forgot to take picture of my PCB. But I will put
Don's schematic on my website this week.
Take a look... http://homepage.mac.com/jfmenard/PhotoAlbum55.html

P.S. Many thanks to Don W3FPR for his help. ;-)
