JT65 on 6 Meters

[Tom D.]

Hello PNWVHFS de Tom WA6OSX CM98ig near Sacramento.

When you read about JT65 on the net and various email list, including this one, one finds a lot of differing opinions...

I find lots of activity on 50.276 via pskreporter using "JT65HF", copied bunches myself and successfully made some QSOs there too.

But what is the consensus in the PNWVHFS group?

What should I be running to work into the PNW with attempting randoms or when making schedules?

Finally, I'm looking for stations in southern Oregon, northern NV etc that are too close for MS but might be suitable for JT65? WB6FFC? Others?

Thanks Tom

There was discussion; was there a consensus?
I'd like to hear the outcome and hope that someone will offer a summary.
I'd like to be a station in southern Oregon working digital modes during the June VHF contest. My goal is activate the grid corner DN02-03-12-13 and reach as many people as possible.

Once again, K7NG (ops AI7RR, K7NG and maybe a guest NF7R) will be active for the June VHF Contest from CN72. 6M figures prominently in our setup. We are putting more emphasis on the digital modes this year and expect to be available on JT65 and FSK441 (as well as voice) as much as we can.

2M both voice and digital, 222 FM and 432 (any mode that we have available) will also be in the mix.
We're receptive to suggestions, opinions, and skeds.

73, Dave K7NG

Barry and all:

Well I am just reading the mail on this but if JT65HF is incompatible
with JT65a (as I've heard it told) that is just a terrible mess made
by the developer of JT65HF. Why I say this is because it leads to
just the questions voiced here on the list and to unsuccessful
contacts by those who are unaware.

I suppose this question offers another one which each of you must ask
yourself: "am I a HF ham that just ventures onto 6m for a little
skip (or something more interesting to do)? Or am I a VHFer who is
"seriously" interested in the VHF+ bands?

JT65 grew out of JT44 and was created about 2003 by Joe Taylor for
weak-signal eme after creating FSK-441 for meteor scatter. Joe has
explored application for JT65 and written several variants for
special kinds of operation and bands. Usually they are not
compatible with his other modes so one has to run the correct mode
(on both ends of the contact).

I have WSPR, WSJT, and MAP65 installed but do not have JT65HF as I do
not run on HF (with much of anything including CW/SSB...etc).

So "you" need to decide as a regional group what you will run for a
digital mode, else disappointment will be the result. I'm not in a
position to "tell you" which.

I will be running the modes in WSJT for eme, ms, and 6m-up!

PS: I just bought a second surplus (NIB) KLM 7LP antenna to convert
for a second 6m 6-element yagi to increase gain to 16 dBi. It will
be later in summer till its up as I have to accumulate the funds to
build the elevation system so I will have az-el on 6m (raising two
30-foot boom yagis is too big a project not to do it right).

PSS: this should be good news for those needing AK for 6m-WAS.

Hello everyone....It is true that JT65HF is not compatible with WSJT as the HF version does not understand the shortcut messages.  You can run WSJT-X instead.  It will work with JT65HF.  The screens are a little different, so you need to play with WSJT-X a bit before the contest.

However, if you are going to do Meteor Scatter or EME, you should use the real deal....in other words WSJT. 

Now that we can Announce, there is less of a chance of stations being on incompatible modes....IF we could figure out where to Announce.  No consensus has been reached on that.

For the upcoming contest, I will be on PingJockey whenever I am doing meteor scatter and I will be on the N0UK EME-1 page whenever I am doing EME.  Those seem pretty standard.  However, there are some guys that insist that the ON4KST pages must be used.  Well, maybe.

After a couple of contests, I hope that this can be worked out somehow.....

I've been playing around with PSK31 , JT65a, And FSK 441 much for the same reasons , however I'm trying to use these with my rover set-up.

Right now I'd just like to pick one for Terrestrial work( JT65a for 6m) and like Marshall says the rest can be announced.

Maybe I will explore setting up a web page with a chat program....Good Grief what am I getting myself into now!!

[Marshall-K5QE]

Hello to all the PNW gang....It really is important that we all use the same "watering hole".  If we don't, people will be spread all over the place and no one will be able to find them.  I think that we already have standard reflectors / chat pages for FSK441 meteor scatter(PingJockey) and for EME(the N0UK EME-1 page).  I will be using those.

Some have insisted that we all should use the ON4KST pages....which duplicate the above. 

I don't think that we can have only ONE place for Announcements....the country is too big and the modes are different.  The east coast guys seem to think that the packet spots are all that anyone needs.  I disagree on that.  I want to post "CQ CQ de K5QE 50.265MHz FSK441 First Sequence"....I don't think that you can get all that on a packet spot.  Just knowing that W7XYZ is on 50.245 is really not enough.  He does not know that you are calling him or which way to point his antenna. 

There is a lot to be worked out here....maybe after a couple of contests, it will all shake out.  If anyone has any genius ideas, now is the time.....

I would like to echo Marshal's request for one "watering hole".  This could get ugly if we are trying to monitor 4+ bands AND several chat rooms.  I am not sure if ON4KST is the answer as they seem to be band specific (and my password no longer works...) and creating our own just might add to the mess.  There has to be ONE good existing chat room along with ping jockey we can all use.  Don't want to spend the whole contest in the chat room either.  This is supposed to be a RADIO hobby...

I can't see myself using chat rooms 'n stuff during contests, but I might.

Of those sites mentioned, I think the N5TM chat room might be the best place. Ping jockey is a mess and ON4KST is pretty specific.

And let me add a request for a std calling frequency for eme, ms, and tropo on 6m.  Probably need a tropo digital calling freq for bands up to 1296.  CW/SSB and eme are well specified for 144 and up already.  At least an agreement that applies to PNW+AK+border states to the region.

ON4KST seems to be where 6m crowd gathers (but I am not a frequent player on 6m).  N0UK-EME-1 for 2m eme and ping jockey for ms.  HB9Q chat for eme on 432+.

With the opening of chat rooms and other assistance for ARRL Contests, real-time skeds will be more prevalent (especially to the more remote locations).  It appears to be now std practise amongst eme'ers for daily operation (whether they will admit or not), so I would expect its use to increase during ARRL contests.

The main need is for tropo digital operation as eme and ms are better established.

PS: an earlier post I alluded to 6m-eme operation but I am not yet QRV with QRO power.  I do have a single 6-element yagi up with 125w for 6m openings and soon will have my preamp installed on the tower now that wx is nice.  I'll announce when I am QRV for serious 6m-eme/ms.

The calling QRG for MS is 50.260 and is usually coordinated on ping jockey.  Call on 260 and listen either up or down.  Then move is someone calls.  JT65a or HF is 50.276 and PSK has been on 50.290 I believe.   I usually monitor 50.276 for weak Es and tropo openings when band appears dead.  It is amazing what shows up in the morning sometimes.  Even if I am not in the shack, if I see a call and grid that I need, a simple email setups up a sked.

 

I don’t think a calling QRG for EME is good.  Basically best to coordinate skeds or activity using  the common chat.  ON4KST seems the best.  Normally activity is 50.185 to about 50.210.  With most activity 50.190 to 50.200.

Getting caught up on the e-mail; busy day!

I did not mean to imply a calling frequency for eme but the range on 6m is a little uncertain.  50.185-59.210 gives one a place to operate separate from ms or terrestrial digital operation.  50.260 I knew for ms.  No psk-32 activity up here on 6m that I am aware of.  JT-65 would be better for weak signals.

Common to all these is probably making skeds vs random calling (especially for eme or ms).

So a decision on what chat room/logger is needed.  Be nice if it was not one that has the whole lower-48 logging onto for terrestrial attempts.  For ms or eme I guess a wider use is good.
