cobra 25 ltd classic st/mosfet

Thank you for the chart and information! Great read. I was only thinking that it might be cool to have a radio with no Amp go double the distance as a stock radio.

doubling your power is good for about maybe 1/2 s unit on the other end, not so much for increasing range. a final swap is more for propery driving certain amps with a high swing from a low DK.

Yes only 1/2 s unit. I was thinking about two FETs as the final. I get 8 watts carrier and swing to 40 watts at like 16.5 volts. So my thought was to use dual fets and get a 16 watts carrier which according to the chart I read would double distance from a stock 4 watts radio. But I get stoned alot and have silly radio thoughts. Usually not practical thoughts at that.

i think if you want to do dual final mods, galaxy is the brand you want if you can find one cheap somewhere in the wild. they leave the area wide open. i dont see an easy way to do duals on a 25 unless you are making a stinger

Thanks for the info. I'm not technically good enough to do that. I have a local guy here that does my radio work. Thanks again

looking for info on how to do the IRF520 mosfet upgrade to a cobra 25ltd classic st. need info on the parts and the installation. and what i should expect on the output after the installation. then i'm gonna do the swing kit utilizing the cap and the resistor. gonna set it up to use it with a killerbee 250hd linear

Hi if I change the final to a mosfet.. Shouldn't I also chang the driver to a mosfet?

depends on the chassis
