The 80m proposal should be approved because the ARRL is going to push 11708 to the end of time. They will eventually get it through. And when that happens, the added 50 Khz on 80m will buy a small am
Michael, Sounds good! 3Khz or 6Khz setting is about the same on the 950. And try to use as little preamp as you can manage. If signals on the bands are weak anyway, then it's not much problem anyway.
The best adjacent band rejection I have measured is off the Array Filtermax 6- band unit. Amazing. They will run 200w just fine. I run the 5B4AGN units here which don't quite have the same rejection
I've built one of those that we used in FD last year with excellent results. Pretty easy to build but you really need a VNA and a lot of time to get the thing tweaked for it's maximum performance. It

I also don't call QRL in RTTY contests. As Jerry suggests, I determine where I'm going to jump TOO by looking at the bandscope. Then I jump and start calling CQ. If there is another guy who starts ca

It's not about speed at all, it's about preventing confusion when state is part of the exchange. Especially when you add in some band noise, a QRP power source, poor antennas, QRM and operator fatigu
It's probably going to be solved by Alex adding some more AI into the pattern decodes. Trying to get the world of RTTY contest participants to follow a certain format is impossible. After every conte
Alex, Unless you know you have a monster signal at the DX location, you may want to try at the edges of the pileup, especially if you notice the guy moving around quite a lot in the pileup. The pileu

Huh? Spend any time up above 14.090 and you can pretty quickly realize the supposed "prevent interference" aspect is completely absent with those stations starting up on your QRG pretty often. And in

Maybe it's my paranoia or imagination, but it seems to me that guys supporting 11708 are generally very careful to avoid saying "it would be a huge boom for email-via-HF!" The fact is the R&D for wea

Was there a reply to this? I think I have missed it if there was. If not, maybe someone else can authoritatively answer. I am genuinely interested in understanding this one specific concern. 73/jeff/
These are all good points to make the the FCC. I don't personally have any bias against the email-via-hf as a project. What I don't like is the side-step the official rules mentality that the interes
