Re the intermittent receive signal strength. You may have a bad reed relay. The
reed relay shorts the Receiver input to ground when Xmiiting.When receiving the
signal goes through the reed contacts
After many cycles the contacts get corroded and give you weak signals, by
cycling the xmiiter on and off it may improve a bit.
It needs to be replaced or rejuvenated. The relay is about $30 from TT. I
rejuvenated my Omni D reed relay by removing the swr board and cycling the reed
relay coil about 20 to 100 Hz while running a small current ( maybe about
several hundred milliamps ) through the contacts. Check with an ohmmeter
occasionally until the resistance is zero. You may be able check the
resistance without diassembling any thing by measuring the resistance from the
xmitt ant. jack to the receive ant. jack, at least that is how it is on my Omn
D.
Hope this helps. Best regards, el rob
