To All,
I have just purchased a kl500 to install with my 2950dx in my mobile. Thank you Copper on the smokin deal you gave me on the amp!! :-)

1) From what I have read about the amp I need to set the dead key between 1-4watts on AM. I want to set it so when the radios RF power knob on high, deadkey is no more than 4 watts, correct? The radio will deadkey around 1 watt with the RF power turned all the way down.

2)Set the high side of RF power so it swings no more than 16 watts on AM, 1-4 ratio correct?

3)SSB needs no more than 10 watt dead key when RF power knob is all the way up, 1-4 ratio equals a 40 watt swing correct? Is the deadkey to high on SSB?

I ran 8 guage wire to the batteries,(F-350 with a diesel w/ 2 900cca batteries :-) ) . Can I run the 2950dx and the RM500 on the same line from the battery? Maybe 6 gauge would be better?

Sorry for all the questions, but I want nice clean audio and power. Just trying to do it right the first time! No over modulated splatter box for me! Please tell me if I am missing anything!!!

Thanks beantown

P.S. I know, I know, ground the daylights outta everything!

There is no dead key on ssb,the meter swings only when there is sound present in the mike,6 gauge would be better for runs longer than 3 feet with that amp it can draw 40 to 50 amps,I would not recommend tapping into the 6 as there will be large voltage and current swings on ssb and you need good regulation for your 2950dx,I know it's a lot of extra work but when you're done you WILL NOT HAVE A SPLATTERBOX,provided you haven't disabled the amc in the radio,leave it and you will be smooth and sublime.Bigbob

Also I would suggest keeping the dead key at around 1 Watt. It will run cooler that way and will prolong the life of the amp and also in my experience give you much clearer tx.
My 500 will still get warm if I get long winded so I went to Radio Shack and spent $20 on a 4.75 inch 12V cooling fan and using some small bungy cords I had lying around attached it to the amp. I spent another $5 on a cigarette lighter adapter and wired it up. When I start talking for awhile I plug in the fan. Works slick.
Great amp, just don't overdrive it.

dunno if u have your amps ground runing to the battery('s) but the shorter the ground the better run it to the chassis is your best bet and i heard its better when every thing is grounded to the chassis then to just the battery.
