Help I Installed A RFX75 Cobra 29 Squeals & No Modulation

[9C1Driver]

I have a great idea, send it to this guy. He has installed an RFX-75 on radio's other shops won't touch. Custom CB radios you will be glad you did.

Put an RFX-75 on my 29LX without the variable power mod done yet.
I had to size a resistor that is across the cap I installed where JP36 was. This let me get the DK below the recommended 15 watts.

THEN I had to adjust the variable on my 12 VDC power supply. Don't understand exactly why, but the voltage supplied to the radio has a large impact on the dead key wattage with this set up on mine. IMO it is too sensitive to the voltage supplied to it.

I'll probably end up doing the variable mod to the RF gain pot like others have done.

Take that piece of crap off and restore the 29 to stock and just run an external amp.....

Rfx's are a waste of time and money IMO . A good tune from a stock 29 will hammer anything else out there throw a amp behind it as previously stated and rock on. I will not run another brand of radio other than my Brownings you could say I have a love affair lol. Buy a good mic get a good tune and good amp and antenna/coax system and do the dang thang
