ICOM ic-746 no voice transmitted

I am new to ham radio. For my first hf radio, I bought a used ic-746. It has been working on all bands except 2 meters. I can receive on 2 meters but not transmit. It seems to be transmitting a signal but not transmitting the voice. I use a ht to determine if the icom is transmitting. I set both radios to the same frequency. When I push PTT on the icom, the green receive light on the ht turns on but when I talk into the mic, there is no sound on the ht. Unlike other bands, the Po and SWR meters on the icom do not move when trying to transmit on 2 meters. The power supply meter moves a little when PTT is pushed.
Any ideas or suggestions?
Thanks,
Dennis KD0TTF

Dennis-

I am trying to understand your problem. The IC-746 Po and SWR meters
would vary on SSB and be steady if you are transmitting on FM.

If you are transmitting on FM to an FM HT, you might be overloading the
HT. See if it makes any difference if you disconnect the HT's antenna.
Just do not transmit on the HT without its antenna!

It also sounds like there might be a PL/CTCSS tone set on the HT's
receiver, but not on the IC-746 transmitter. Dennis, you might want to
check to make sure all tones are turned off on the HT.

The IC-746 has no meters. It uses a large LCD display.

Which are giving a readout, so become meters. My digital multimeter is
still a meter, despite an LCD readout.

I'm surprised you didnt' quibble about "2 meters".

Some do seem to get bent out of shape over the small things. I have a 746
pro and while it does have a LCD display, I still think of the part that
shows the SWR, PO, S and other things as the meter.

I worked at a place that when it first started out they had a large control
room with hundreds of paper chart recorders and knobs to adjust the
settings. As we moved to computer control and computer screens and
keyboards, the display on the computer screen was still called charts by the
operators and others.

Not sure if he is into shooting or not, but bet he gets bent out of shape
over calling the magazines clips.

The ICOM 746 Pro is a over glorified CB radio / hamshack in a box.
It was junk when it was new and it didn't get any better with age.
If it is broke, put it in a box and send it back to Icom and tell them
to fix it or just don't use the 2m side of the radio...
That is the best advice I can give you.

Alternate advice, sell it and buy something better, or get a big sledge
hammer and smash it and then no one will ever have to look at it again!
