I have an old 144MHz rig from the 2000's, an IC-271. I am trying to get it up and running.
Summary of the problem:
I can receive fine on the rig, except for from my HT.
I can transmit a strong signal from the rig, but not my voice.
Are there any simple operator error explanations for this behavior?
Or does it seem like an electronics problem inside the rig?
All troubleshooting attempts:
I have an appropriate power supply (DM-320MV), a brand new microphone, and an antenna. (two, actually, one homebrew, one a 50 ohm impedance retractable Diamond RH775, which is for an HT, but I can use it with the rig with a connector, at the rig's low power setting).
Scanning the air, I pick up conversations loud and clear.
However, strangely, the rig cannot receive from my own HT (have used the HT for contacts, so I assume it is in working order). When I transmit from my HT to the rig in the same room, the signal meter on the rig goes up to 60+ dB (off the chart), but I don't hear my voice. I am testing with the squelch open, and the static noise becomes silent during my HT transmit.
In reverse, I tried transmitting from my rig to my HT. The rig's meter shows RF out, and my HT picks up the signal, but again I do not hear my own voice.
Finally, one more test: I tried to contact a friend (several kilometers away) with the rig. I could hear his voice clearly, but he could not hear my voice, only silence during my transmissions.
I read the manual for the rig and checked how each setting should be. On the rig, I have all tones/special processing circuits, automatic gain control, etc turned off. RF GAIN is set low. The rig is in FM mode, as is the HT.
Basic electronics knowledge, have read the manuals of the radios, have done some ham radio activities years ago under supervision from pros. Otherwise a newbie.
