The earlier comment about reading the Handbook is a good one, and if you're interested in a more in-depth but very readable treatment of the topic, I recommend "Reflections II" by Walt Maxwell, W2DU.

I thought mine had a birdie on 50.125, but when I replaced it with an IC-706, it heard the same birdie, as did another 706 in my truck. It did have its own real birdies, but some of them aren't recei

Randy, I just replied about that 'birdie' that clobbers 50.125, and I noticed when I got in my truck, tuned to that freq, and then backed out of the driveway and away from the house, it went away. So

Yes. The RTTY filter is built for the first IF (9 MHz) and is already shifted. The 2nd IF, 6.3 MHz, needs to be offset to match, so, yes, that turns out to be just where you have it set. Remember, ce

Is that 300W out RMS or peak? If it's RMS, you're really pushing it HARD! If it's peak reading meter, you're probably still pushing it. If it's LED's then maybe you have a concern. (I can't recall if

Jim, If you use a Bird 43 on SSB, you'll need to either run tones or use a 43 with the peak reading kit in it. They have a very slow meter response. 73, Duane Duane Calvin, AC5AA Austin, Texas www.ac

Interesting. 2250 PEP SSB = 1590 W RMS. The Alphas are rated 100% duty cycle "brick on key" at 1.5KW, so 2250 SSB PEP should also be pretty much loafing for the Alpha 87, 89, 91b or 99 or the others
