My Scout's meter is behaving strangely. Actually, I think the meter is
OK, but the supporting circuitry is on the fritz. Perhaps someone here
with more electronics experience than I could suggest some test
procedures or likely components for failure?
- With the rig idle, regardless of whether the meter switch is swr or
fwd the meter "twitches" upward half scale about every 5 to 30 seconds
- Fwd power seems to indicate correctly, but if I'm using Tune as soon
as I switch it off the needle rises to 3/4 scale then drops to zero.
Doesn't seem to happen if I just key the rig.
- The needle deflects left (down) in SWR mode regardless of the true SWR.
Voltage at the meter is about .1V at idle, rising to about 2.5V on Fwd
mode, 30W out. The coil measures about 2K ohms.
