Was there any more recent info on frequencies for field day? When I did some google-searches this evening I didn't find anything other than a couple old posts where people in random forums said they planned to check the usual frequencies....I'd like to try and figure out a plan by this weekend so I can get all my gear tested and packed up in advance of the big weekend... -Matt / KK4NDE -----Original Message----- From: Bill Frantz [mailto:ae...@ar...] Sent: Sunday, June 02, 2019 1:24 AM To: WSJT software development Subject: Re: [wsjt-devel] Proposed FT8 Frequencies for ARRL Field Day On 5/30/19 at 11:17 AM, wsj...@li...

> Was there any more recent info on frequencies for field day? https://groups.io/g/FT8-Digital-Mode/message/2202 has a different plan with (for example) 14130 instead of 14080. That might be a better place for discussion, because Field Day frequencies for this year probably won't have a direct effect on WSJT-X development. https://www.arrl.org/files/file/Field-Day/2019/2019-Rules-RevA.pdf says a club may operate on 20 FT8, 20 CW, and 20 SSB simultaneously (6.3, 6.7). Depending on equipment, antenna spacing, and the relative skills of the 20 SSB and 20 CW operators, a 20 FT8 signal might interfere with 20 SSB more than with 20 CW, Or vice versa. One question is whether the 14130-versus-14080 choice is important to the more common case of clubs who plan to operate 2 (not 3) stations on 20m at the same time. For example: Many clubs have a station tuning around all of 20 SSB (14150 and up) to look for new QSOs throughout the daytime. They do this every year. Their station isn't big enough to call CQ and run stations on 20 SSB. This year, someone wants to add a second 20m station that transmits very frequently on 14130. Would that often be a realistic conflict? Conversely, a club may be historically successful with S&P on 20 CW. This year, someone wants to add a second 20m station that transmits very frequently on 14080. Is it realistic that they'll make substantially fewer CW QSOs on the high end of 20 CW? Matt, KA1R |

Interesting, that's another different data-point for frequencies to use (I'm not familiar with that groups.io but I think that site is where I had seen talk of checking "the standard frequencies"). And just today there was a big fuss on the repeater a number of guys saying how "digital especially FT8 is jamming and spamming over CW stations down in the CW part of the band"...so I know I have to be rather careful being able to cite why I pick where to use. Yes - the club I'm in arranges how many stations will be doing what, they've got "generally" stations one SSB and one CW per band, and then I'm tasked with "digital modes" open ended no band restrictions (well, within the field day rules). I have done RTTY and PSK31 in years past, this year I'm hoping to do better with FT8. Nobody has complained about interference from me in the past...but the CW stations always obliterate my digital reception and sometimes kill SSB too. I guess I'll try and build a configuration in WSJTX that has the standard frequencies as well as the ones listed in this thread and on the site you linked...shame there doesn't seem to be more coordination as to where to operate for field day. -Matt / KK4NDE -----Original Message----- From: Matt Power [mailto:mh...@mi...] Sent: Wednesday, June 12, 2019 8:30 AM To: wsj...@li...

Matthew, It is an interesting question. We are going to stick with the *.080 frequency recommendations. We have suggested that the CW boys and girls try using their notch filters and "yes" technology marches on and they will loose a little tiny piece of spectrum.
