Depending on the meter that you have you should get a reading of between 400
and 700. My Fluke 77 shows 453 on most Astron's that I have serviced. If you
have a short between any pin and case or between pins the transistor is
defective and must be replaced.

Nobody is asking the obvious. Where is the watt meter? If the watt meter

Was it originally a 25, or 40 watt version?? A 40 watt version at 15
watts will most likely be spurious and inefficient (Motorola rates them
down to 20 watts (50%)). The 25 watt version only draws a max of about 6
amps at 13.8 VDC, so it will probably be about 4.5-5 amps at that level.

Rod,
The Service Manual for all models of the GM300 is 6880902Z32 and costs
about $12. On Page 14 it states that a model M03GMC draws about 4.0A at
10 watts, and a model M33GMC draws about 7.0A at 25 watts. Based upon
this information, I'd expect the latter model to draw around 5 amps when

Dave is absolutely correct. The original post states 160 Watts in to the
duplexer and 130 Watts out. That equates to less than a dB of loss through
the duplexer ( .9 db to be more accurate ).
