Mic wiring for tyt -9000


since this is a fairly new radio, your only resource is your manual and schematic.
As a Ham you should be able to read them. If you are thinking of installing an aftermarket mic, you don't do this on most ham radios, they are not CBs that you can put a "power mic" on. too much audio input on an FM transceiver can make your transmission unintelligible

What frequencies I can use vertex VX 400 U radio


Hi,

Not sure what frequencies are allocated in India for UHF ham, but may i direct you to the following: join yahoo group specific to your radio Make/Model, there you can get info and you can download manuals, schematics and other goodies.

I'm sure, but not 100%, that ham bands around the world have similar allocations on 70 cm band UHF, but as I stated, not 100% sure.

Best regards,
Peter

My radio smoked when turned on


I need a schematic for a IC230, 2m ham radio.
Using a can of freeze mist did not solve the problem.
I am an electronic tech, and a schematic would be most helpful.I need to check voltages.
