[VHFcontesting] Microwave modules transverter question

[Tim Coad]

I have 2 different Microwave Modules transverters... a 28-222 and a 28-432
and they both have the same problem- Almost no output power.

When I got the 28-222 it was working fine, but then the output power started
getting flaky and after a bit the power out no longer registered on the
power meter, but it was still transmitting at a very low power. It receives
fine.

I just picked up the 432 transverter, and it has the same problem. I can
hear it fine on other 432 rig, but it does not register any pwr on the
meter. I do have the jumper set to take 5mw drive.
Has anyone had the same problem?  Ideas?

Actually there's one more compliaction with this one, which may or may not
be related to the low power out. Someone modified it to have a 27Mhz IF
instead. If I drive it with 28 Mhz it transmits at 433MHz.
Could transmitting 1Mhz high cause it to have a great reduction in output
pwr? Anyone have an idea of the output bandwidth range? I do not have
capability to drive it with 27Mhz to test it.  (Also..how do I retune it
back to 28MHz?)

Thanks
