Hello CW: We have a local that runs a RFX 85 on his radio, and sounds pretty good. Don't know what radio he has. But That RFX 85 would work quit well with a U980 radio that has 12 watts out, I believe. The RFX is a biased amp and has a low pass filter in its output. See:

It's pricey as the purchase and install cost approach the cost of say a Texas Star 350 having two RF Transistors (Pills) that would do 250 to 350 watts. But a U980 with a RFX 85 then could drive a 8 Pill amp with close to 1 KW out. There's many options. But running a stock radio with a external amp is the way to go I think. Your millage may vary....

Last week end was a total Gas as we went four wheeling all over the El Paso Mountains, plenty of good times, Formal and informal BBQ, Pot Luck, Steaks, Hot Dogs, Hamburgers, fried fish, salads, and way too much totties and rock n roll with country western, both kinds of music. Gun shootin, skip shooting, hiking down some ravines, exploring mines, observing the celestial star formations (Oh there's a pretty one), got see a military Helo come in doing Navigation exercises real close and low, they buzzed our camp ground and waved. War stories, X wife stories, and a few sing alongs around the camp fire......
