Hello all - I am trying to help a friend of
mine get a Mastr II mobile fired up on 2 meters.
We are having trouble getting any thing out of the
transmitter. Receiver seems to be working OK although I'm sure it needs tweaking
a bit. We cut off the control head and built a small circuit similar to the NHRC
Vol Sq pot assy. and that is all working fine. I was told that you would get 10
volts to a pin on the transmit icon when you went to the transmit mode. We have
one pin ( I will call maybe pin 6 for the icon that has 10 volts full time
- the one next to it ( Pin 5 ) has about 5 volts full time. I see nothing else
changing on any pins whether in transmit or receive. What on earth are we
missing here. This is a first for either one of us. The receive does drop when
we tell it to transmit so I feel confident we are keying it correctly. I
know the TX is out of tune but how or where to begin when it seems there is no
output anywhere at any level. Also have a second transmitter and same problem so
I feel there is something we are obviously missing. Dave /
