Re: Field Day frequencies for FT4 and FT8 (see much discussion down below)

Use the standard FT sub-bands.  If they get too crowded or if you don't want to QRM non-FD ops there's nothing to stop you from moving up above the normal FT sub-bands.  These higher frequencies are claimed by WSJT-X for other, largely unused modes but apparently aren't to be used for FT.  I have not seen an explanation why.

The WSJT-X standard suggestion is to move up in two kHz steps in contests when bands get crowded (WWDigi rules):

Set the radio dial at the bottom of the sub-band and work stations on audio frequencies within the radio passband typically 2.5-4 kHz wide. If a sub-band becomes crowded, move the radio dial frequency up in 2 kHz increments, as needed.

Of course, they are talking about moving up from separate contest sub-bands, but there's no reason it can't be done with the normal sub-bands.  Same principle.

 

Set your dial frequency up 2 kHz and you will overlap with the top 1 kHz of the existing sub-bands (already a less used portion).  Or you could go up 3 kHz for complete separation but still be adjacent.

It seems unreasonable to expect FT people to tune around looking for random operation away from the normal frequencies.  FT is a very compact mode in terms of frequency use.  It should easy to find contest sub-bands, but the best ones are right next door to the existing ones.

"Word of Mouth" is wrong ... there are no specified frequencies for Field Day.   Just use the standard frequencies and answer people calling CQ FD.

I can not find anything as such. Am I not finding the correct ruling for digital progam contact?

Thank you and good luck to all this weekend.

Maybe the mostly dead spaces at 7100-7125, 14100-14150, 21100-21200

 and 28100-28200 could be used  for those 27 hours. Temporarily pick a

 freq or two in those areas. This is mostly a Domestic event at lower power

 having little effect or interest outside US/Canada. Just a suggestion.

Because it's inconsiderate of the non FT-8 etc. operators. We have our own segment, live with it, for 27 hours and let the other freq's alone. Moving off is understandable for a DXpedition which goes on for days and involves on station (on the far end).

Taking an entire contest community off our segment and splashing all over another segment is simply selfish.

On weekends, there's a great deal of FT8 activity on the standard FT8 frequencies without a contest taking place.  I expect the FT8 activity will increase greatly during Field Day this weekend which will make it impossible at times to find a reasonably clear frequency.  Since a WSJT contest mode is going to be used for FD, wouldn't it be desirable to use a FT8 contest frequency?

"Why would they be any different than normal? SSB and CW take over their entire segments for FD, so I would expect no special freq assignments for digital".

I want to use my 7100 on Field Day for FT8. It’s actually the perfect radio for FD because it has all bands. I have used it for PSK and never noticed a significant issue with bandwidth.

In prepping, I found I could not expand the FIL1 bandwidth past 1.4k on USD-D. Does anyone know if there is a workaround or a fix? I can get 3K on my 7300 but don’t want to take it to the field. I noticed on the FT8 bandwidth that the bright yellow ends that reflect the available bandwidth show my viewable bandwidth to be greatly truncated.

Help?

Cross-posted to WSJT-X group too.

Bill - I see the same thing with my IC-7610 while running 2.2.0.  If WSJT-X is running and I turn the radio off using the power switch on the radio it will come back on after a couple minutes.  I have to close the software prior to turning the radio off.  Since I cover my rigs when not in use this can be a problem if one is not careful.  Don't want the radio running while under the cover.

Dear Users,

Recently I upgraded my installation Debian Buster from 2.0.0 to 2.2.2 and I saw that the Hamlib Rig/CAT throws an errorr about geting the VFO.

After some investigation I managed to narrow down this  to the changes from:

last working version: 2.1.2

first non working version 2.2.1


I guess this is due to the change on hamlib 4.0

I have the same issue installing on both methods either using the .deb file and compile from scratch.

I do not know how should I report this bug. I have seen some post about this without answer. is there any place to fill a bug report and do the following of it?

is there any way I can help to fix this? I have very little knowledge on C but I have the radio so I can do some testing if instructed.

can someone clarify if this si ssomething we should manage from wsjtx side or from hamlib side? I do not know where the bug exatly is.

Thanks
