How to cause massive Ham Radio QRM with your ALC in Digi Modes

I have since learned that some radios are more susceptible to causing this problem than others, however in my opinion, keeping your ALC to tick-over and no more will be the best policy.

Check the film.

Success rates calling CQ on BPSK 125 Digital Mode

I’m currently using DM780, parrt of the Ham Radio Deluxe suite of programs to conduct my digital hobby. Some of the modes are extremely fun – and I particularly like the very fast speed of BPSK125.

Recently, I have improved my very success rates calling CQ with this script:

5 CQ CQ de MØMCX MØMCX
4 CQ CQ de MØMCX MØMCX
3 CQ CQ de MØMCX MØMCX
2 CQ CQ de MØMCX MØMCX
1 CQ CQ de MØMCX MØMCX
PSE K<stop>

I think it mst be quite a compelling trace to follow on the waterfall because once I get to zero and ask PSEK, I more often that not get a hit. It’s certainly better than the old standard :

CQ CQ de MØMCX MØMCX
CQ CQ de MØMCX MØMCX
PSE K<stop>

But it’s only for fun!

See the problem below
