Sometimes I have a good enough signal to a repeater that I can key in,
but not enough to have anything other than a carrier signal get
through. Now, if I'm trying to get attention on a repeater on, say,
the 2 meter band, how do I know whether I'm full quieting and there is
just no one listening at the moment or I'm having problems getting
through? A friend suggested having a scanner handy with earphones to
listen to myself on the output freq. I tried that and it didn't seem
to work at all.
I'm using a Kenwood TH-F6 to transmit on 2 meters and I have an Icom
R3 tuned to the output of the repeater I am keying up. I don't have
any problems getting into the repeater and everyone seems to hear me
just fine. The only thing is, I can't hear myself through the Icom
when I transmit on the Kenwood. The Icom is functioning otherwise.
It picks up the output of the repeater without issue unless I am
transmitting through it with my TH-F6. For a moment I thought that my
hearing was to blame, so I dug out an old analog oscilloscope that I
had bought at a MIT flea market years ago for about $75. I visually
watched the audio output of the Icom with the scope. When other
operators were transmitting through the repeater I could see their
voices dance on the blue-green glowing screen of the scope, but when I
transmitted all I saw was a flat-line.
Why is my scanner deaf when I'm transmitting with a separate rig?
Could this have anything to do with near-field emissions? I'm
transmitting with 5 watts of power using a 7.5dB gain omni-directional
antenna. My scanner is always within 10 feet of the antenna.
Repeater output freq: 147.000 MHz
Offset: -600KHz
BTW, I've talked with another ham that has experienced the same thing,
so at least I know I'm not going nuts just yet.
