President George FCC

[Overtimeman]

Finally got me a George FCC radio.My present setup is a mobile with a Bill II,with a digi mic,KL300P,and the Stryker A10 antenna.Got the Bill 2 running a watt and a half into the KL300 and everything is fine.My question is about the George.I don't think there is a CB shop anywhere around my 20.Would turning the RF and MIC gain down keep from ruining my amp?Open for any help.I put a lighter plug on and talked some hooked straight to the antenna and contacts said it nothing like the Bill.I haven't found anything about a secret menu on the George.Thanks for any help!

OK I found my answer on You Tube.I wished I grabbed a McKinley 2 just for the smaller size.Too bad they were a limited production run.

No it will not. Mic Gain and RF gain has nothing to do with over driving an amp. Now if that is RF power out that is variable then yes turning down might be helpful but you might still need to turn the low power and high power pots inside down to match drive if that is possible. Depends on the amp and how much drive it can handle.

Basicly you need a radio that has similar output characteristics as the input needs of the amp. Often people will purchase a radio that simply puts out far too much power for the tiny little amp they want to use. If the amp is of suffcient size the input pad can be adjusted to match the radio but that again is not a golden screw driver operation. Some math and some test gear and the ability to solder is a must.

It also matters who made the amp and when it was made really old gear was designed to be driven by 1-2 watts of drive with some swing like 4:1. Modern radio using cheap non-rf fets designed for power supplies and such do not obey the 4:1 rule even if you can get the power down to 1-2 watts you run into two common issues either the radio will not swing now and you get 1-2 watts swining to 4 or you get a radio that keys 1 watt and swings to 60 watts and even though that 60 is PEP their is a limit to how much a small amp can handle even if it is PEP and even if that averages out to 14 watts old small 1-2 transistor amps or 1 driving 4 amps where not designed to function in that way. So you will either be under driving the amp of over driving the amp.

I do not have enough experince with high powered mosfet final radio's combined with vintage amplifiers but we are clearly operating outside of the origanal circuits design parameters. I do know though that even PEP matters at some point I just do not know where that line is drawn in the sand!

Well I have a RM Italy KL703. Haven't hooked it up yet.You can get different opinions from the guys on YouTube.Don't want to mess anything up.On the George FCC you just key the mic and push in the selector knob and you can turn down the RF power.Bounty Hunter

It's easy to get off the beaten path with the II (If you mean the EU version). I put something similar in the car and the McKinley II EU in the closet.
