Just started running a 503hd behind my Stryker 955hpc. So far I'm liking it and they seem to play well with each other. This is my 1st amp and figured I'd go with the hd since I'd only be running it with exports. I really like the adjustable output,although if you read the instructions that's not really what it is.
Living dangerously: remember to let the blue smoke out at 70-mph while trying to keep 77,000-lbs corralled. While smoking. Drinking coffee. Yakking over telephone headset with another driver. In traffic. With a 20-knot crosswind. And a half-eaten McSandwich on the dash. In other words, a snapshot out of a typical morning.
And you reach for the radio volume to turn up a report, hit a bump and grasp the wrong knob . . .
I went with a 30A fused RM ITALY KL7505v. After a Galaxy 99v2.
Amp has three position power switch. Radio has variable power.
On the bench, with radio at lowest setting, and amp in lowest it’s:
2.25w, keying 15
into
40w, keying 180
A “better” radio someday (though it was a distinct step up from before). Was simply glad this (and the rest) was working to spec (on frequency).
Wouldn’t hurt to check numbers on yours, is thought.
Which reminds me. Ran across a post about ARRL procedure to tune both to a 1:4 ratio. Worth opening them up?
