did you follow this info for the install of the unit on your radio? the unit should dead key about 15 watts after the install, not 3 watts as you state you are getting.

Several questions here...
You installed a RFX 75 or RFX 85?
THERE IS A NEWER ONE - THE RFX 95 - please be sure about this...
What did you turn the radio down to - before you installed the RFX unit?
If the radio was left "Stock" it only needed 3 to 4 watts from the radio so if you did any mods to the radio BEFORE this - you'll need to undo them - especially if you did a Swing mod using JP36 method for Cobra 29 models.
The Driver on the radio has to have it's drive level set to drive the RFX unit.
See bottom left corner - JV17/JP36 Mod location...
So if you did a mod to set the swing at 1 - 1/2Watt and go up from there - reverse it out. Then Tailor the "resistor" part of the Resistor/Cap swing combo to THE RADIOS' DRIVER to make the carrier climb to about 10 watts - it needs that as a MINIMUM in order to work properly. IF you wanted swing an amp - do NOT use the RFX to do this - get a separate external amp or modulator instead - the RFX can't work as a modulator - at least not without more help.

THIS IS FOR NON-HD RFX-85 models!

There is also an RFX HD (High Drive) unit that uses less wiring and I wonder if you have that instead?
It only uses one MOSFET...and a BIG relay...
AND - YOU DO NOT REMOVE THE FINAL

So I went back and rechecked all my connections found aloose wire on the antenna hookup now itll do 20 on key up and seing right up over 75 pep!. Im gonna go ahead and put the cap and resistor in to bring it back down tune it up,and were good to go. I really appreciate your input guys.thanks
