Today, on the SO-50 pass, I tried using the Arrow diplexer (duplexer?)
to enable full-duplex using two handhelds. As most on this forum know,
if you use two handhelds with the Arrow antenna, the third harmonic of
the 2m uplink will desense the 70cm handheld, so you can't hear
So, I hooked up what is normally the antenna end of the diplexer to the
2m uplink radio and the 2m radio end of the diplexer to the 2m part of
the Arrow antenna. My hope was that this would suppress the third
harmonic of the 2m uplink enough so that it wouldn't desense the 70cm
handheld. The 70cm radio end of the diplexer was left unconnected.
It didn't seem to work. I made contacts but I still didn't hear myself
Just wondering if anyone else has tried this and what results you got.
