I got a galaxy dx 949 with a wilson 500 antenna. The swr is at 1.3-1.5.
When on ssb the warning light for swr glows brighter as you talk into
the microphone. On regular am it don't do this. What is it that could
cause this? I've got both the stock mike as well as a red devil power
microphone but they both are doing the same. Any ideas? The built in
meter on it is showing that in fact the swr dose increase as you talk on
ssb. But the swr decreases on am when you speak. Is this normal or does
it need fixed.

Don't put too much confidence into any built in SWR meter or dummy
light. The best thing to do is to attach a decent watt meter such as
a bird or coaxial dynamics and take actual forward and reflective watt
readings to calculate true SWR to ensure the accuracy of the built in
meter. Nevertheless, if you are confident that the built in meter is
fairly accurate, I would say that the circuitry driving the warning
lamp is probably out of adjustment. There probably is an adjustment
in the circuit to set the threshold when the light comes on. Should be
easy to find on the schematic.
