This problem is a Connex 3300HP. Good receive, no AM TX.

    All the antenna connections are brand new. I tried a different mic and still nothing. The TX light changes from red to green but NO key up on the meter itself.

    I realize that my radio is defective that is why I posted here, to try to get the proper help. If anyone has the answer to why a Connex 3300HP stopped TXing but has excellent receive, I would appreciate the help. Thanks

    Thanks, I checked all the knob positions and they seem to be in the correct positions.

    I can do the tech stuff I just need a little guidance as the eyes don't work like they used to. I would not let Radio Shack fix a broken window. They do NOT have any qualified techs any more as they have gone to just selling cell phones and other litttle objects.

Check the configuration:-

switch 1. NB/ANL
RF PWR switch. LO
BAND switch. HI
TB switch. ON

Lower knobs set to AM and D/A

This works for me, hope it does for you.

No AM is alsway an antenna problem, if the antenna connections are ok and the antenna checks good then the radio needs service, but 1st look for defective antenna issues like rusted connection or loose wires.

    then there is no other explanation except the radio is defective.

    u never said you thought the radio was the problem, 9 time out of 10 it is the antenna. are u a skilled electronics tech? that is what it will take to repair this, careful component testing is required, a Hands on job. I suggest you let Radio Shack handle the repair.

Does the connex 3300hp have talk back
Any radio can have Talk Back.. all it is is leaving the RX active on TX and the sampled audio goes to the speaker that you can hear....

Hooked up my connex 3300hp backwards
this usually just blows the fuse, check/replace and try again, if it pops the fuse, the protection diode has shorted and the radio needs to be serviced

Got a connex 3300HP has a ranger board and chipset won't modulate recieves fine keys up relay clicks needle doesn't move no voice either cant find schematics
You may have a dead meter.
Modulation is audio's affect on swing wattage or pep. Notice that needle moving more with your voice.
Dead key or carrier wattage is without your voice enhancing the power only with mic keyed.
I can only assume that the chipset you are referring to is an ic chip audio or pll which must be working if you are receiving audio.
Check your mic cord................ transmit and modulation and even your receive volume can be affected by the cord/mic plug solder joints or broken wires here.
