works just like others I've used in the past. better than the stock 2sc 2078 in my cobra 29,
got a extra 3 watts transmit with a better swing. not as good as a mosfet 520 mod but you only have to change the final and not all that other stuff like when doing the 520 mod. I now dead key 3.5 and swing to 8. Thats around 17 PEP
