Vertex 2200 won't transmit

Calfd15 · Jun 30, 2016

I have a vertex 2200 mobile radio in my crane at work. This radio receives great I can hear everyone talking loud and clear. They are talking on either Motorola mag one portables or Kenwood portables we have some of both. When I try to talk into the mic on the vertex mobile the light on the unit lights up like it is transmitting and a little light on the Motorola portables lights up like it is receiving. But nothing comes through. The light on the portables lights up green though and when another portable talks the light lights up orange. I have tried a different mic on the vertex and same thing. Is this a programing issue or something completely different. Thanks for your help.

Likely a programming problem.

Good thinking on trying another mike, so that probably eliminates the mike or mike
circuitry. You may have a failed Q1009 TX output IC. You would have to get a power meter to
do a test of the transmit output power to confirm. Depending on the model, a VHF VX-2200
will put out up to 45 watts; a UHF one up to 25 watts. Do a search in this forum on the VX-2200
as there is a post from a Vertex Technician on how to check if the Q1009 IC is bad. Not uncommon
for these to fail. If the test confirms that the radio is putting out the proper power, then there's
something wrong in the TX audio circuitry.
It the radio is still under warranty send it back to Vertex for repair. If out of warranty it would
probably be cheaper to get another radio, unless you have skill to replace the IC or know someone
who will do it for you, if indeed the Q1009 is bad.
