Re: 17m PSK31


I didn’t want to open up  that can or worms but since it has been I follow the WSJTX yahoo group. There was a thread today about needing to expand the FT8 band because it’s so crowded. One suggestion is to expand into PSK band.

I know there is no legal binding in the band plan, but how did we end up with the current agreements and frequencies? Is there no protocol to establish agreements? ARRL help? I have the greatest respect for Dr Joe Taylor but how is it that someone can write a program / mode and decide this is the frequency of the mode without coordinating or asking ? Or did he?  Just trying to understand how we got here.

Well fellows, this seems to be a problem on many bands now.  The FT8 group seems to have chosen frequencies without regard for other users and since it seems to be the hot thing now FT8 users are blanketing those areas.  The EU window for Hellschriber uses was 14074 and a couple of weeks ago, I got an email from one of the authors of the article in QST tell me that I should change frequencies since that is now the FT8 frequency.   A lot of other digital mode users have reported the same problem with FT8 users invading their normal frequencies.  From what I understand, originally the FT8 frequencies would be 2 khz higher that JT65, which would have not caused problems for most other users of the less common digital modes, but somewhere along the line that has changed.  The frequencies are included in the software so that’s where the gang has setup.  Since the article was published last month it will probably be worse before it gets better. 


I personally don’t use the mode, although I tried it when it first came out and basically decided that is more my computer talking to your computer rather than ham radio.  Any ways my thougths.
