Default odd readings from watt meters

that sounds like something is wrong. try a whistle, see if that gets the
external meter to move properly. then try cw up in the ssb band and see
that the swr isn't wildly different. make sure that the meter you are
watching on the radio isn't the alc or swr or mic audio or compression
instead of power output also, some radios use the meters for multiple
things and it could change without you noticing from cw to ssb since cw
doesn't have mic audio or compression levels.

Hi, I have put up a dipole and I admit it is not a very good one, about
20 feet up, approx 60 ft. It works great as a receiving antenna and I'm
having fun listening, but so far no one can hear me. I have an Icom
IC-735, and using SSB, the watt meter on the radio shows full power as I
talk, but the watt meter on the tuner barely moves. In CW mode both
meters go all the way. Is this a typical symptom of a poor quality
antenna or does it indicate some other problem (besides my antenna making
skills)?

Any advice is appreciated.

Thanks,

Jim



On SSB, no power output is produced until the carrier (which is later
suppressed) is modulated. Yeah, you could know this, but it is possible that
you do not. This is in case of the latter.

As the previous responder said (my memory is bad - sorry), if your meter is
slow, the modulated voice peaks may not show up on the meter.
