Hi Fred, To pin this down a bit further, maybe you could try an experiment.
1. Set the KX3's RX ISO to OFF. This is a MENU function. 2. Put the KX3 on a freq on 40m. Leave it on RX. 3. Put the "main station" on the same 40m freq. 4. Note if your main receiver can hear the KX3's LO (should be able to hear carrier if RX ISO is OFF). You may need to offset the receiver's carrier frequency a little to hear the carrier from the KX3's LO. 5. If #4 is no, you may be correct. The synth isn't producing any injection frequency. It's a good idea to have some type of antenna, even a short piece of wire, so that the KX3 radiates just a little energy that the other receiver can copy. Just an idea.... Good luck, but with Elecraft support you won't need it... 73, matt W6NIA On Sun, 26 Aug 2012 19:50:27 -0300, you wrote: >Matt, thanks I will do that tmrw.
