Mike,
It's good to hear the problem is resolved, but unless you need the local
monitor speaker on a regular basis, it can signifgicantly reduce current
consumption on the receiver to disable the B+ supply to the audio amp, rather
than run it into an audio dummy load.
A set of instructions I once used for converting a Mastr II UHF mobile for
full-duplex repeater operation suggested removing the audio output transformer
to avoid this problem and save weight. I thought I might one day want the
speaker amp functional again, so instead, I unsoldered and lifted one end of a
large resistor (or two, don't remember exactly,) to interrupt power to the
stage. It's been a long time since I had that manual in front of me, but it was
pretty easy to do.
Good luck with the weather!
73,
Paul, AE4KR

Thanks to all that replied with suggestions for my linking problem. With
all the answers you gave I was able to resolve the problem. The first mistake
was in one radio I forgot to put a load across the speaker connections as I
wasn't using one. ( the other radio I did. must have been one of those late
night deals). Once I did that the hum went away but the audio was very disorted
from the link to main port. Took the audio off speaker hi and connected it to
vol arm. Problem solved and now sounds as it should. Now if it ever stops
raining it will be back to the hill to reinstall at the site.
Once again it's amazing the wealth of information you can get from the
repeater builder group!
Thanks agian,
