This Puts Out ONLY 50 WATTS MAX In AM Mode without Generating BAD Harmonics..Will Put Out around 65 to 70 Watts in Upper & Lower Side Band Modes... 1 & 1/2 to a 2 WATT DEAD KEY is the BEST.. OVER a 3 Watt Dead Key it starts to Drive Backwards RMS Reading on My BIRD METER But Still Drives Forward on PEP Reading on My BIRD METER ..with a 1 & 1/2 Watt Dead Key with a 20 to 25 Watt Audio Swing WORKS BEST ...

I USED THIS BOARD AND I GOT ABOUT 25 BIRD WATTS AND 50 TO 60 PEP SWING. THIS WAS ALL DONE ON A COBRA 29 CLASSIC.I GAVE THE RADIO A 2 WATT DEAD KEY TUNE.BOARD DOES BETTER THAN THE 520 MOSFET CHANGE OUT. ON THE SCOPE IT WAS NOT THAT BAD,WITH A LITTLE IT WAS OK.

I put the stinger board in almost all of my moble radios. I have even put it in i few bases. The output of the board is really set by how good the radio does. The power output is somewhere between 55 to 60 watts.
