Low DK, Max Swing.....for driving an amp?

#51180

Post by Conn »

I love the DX 959 i run in my truck.

I've been looking online at different tweaks for it and have tried to order a few of the electrial parts but haven't found a good source yet. I turned up the modulation, as well as the AM power and it's modulating 100% and swinging about 12 watts dead key.

One of the "tweaks" i'm going to attempt next is the RF output increase.

They say after the mod, that the unit will dead key around 2 watts, and swing around 28.

Why would you want to do this?

I've heard that it helps in driving an amplifier?

Will this help even if i DON'T run the amp?

Excuse my lack of knowledge, i'm just trying to figure out whether I should go ahead with the mod or not. I don't want to have to "re-do" anything.

yes you need the low dead key for the amp. now when i had a 949 I had a 2 watt dead key and swing to 20ish,with out any mods, which would drive that polamer 250( if that is what you are getting or got) nicely, that 949 drove my TS 350 very well

it will work just fine without the amp also

With swing and right tuning Your 10 Watt Signal will Sound like 40 Watts! While the Carrier is Surpressed, Modulation Furnishes the 'Drive' to the Transmitter, by Altering the Timing Constant. Much the same way SSB works.

I have a 959, I run the am at 2 watts dk and get around 12 watts peak, and on ssb peak at 18 to 20, I have the alc about a 1/3 of a turn from full and the meter swings great and good reports, on the outboard I set my power control to a 2 watt reading on the meter and the mic control around 12 o'clock and it drives a palomar elite 250 nicely at a couple hundred, and good for skip...

Maybe I got a bad 949, I hated it, could'nt swing worth crap, and the SSB was horrendous. I got rid of it prety quick. Good luck with yours!
