JT65 Bandplan or Calling Frequencies

Postby VK7MC » Wed Mar 26, 2008 8:17 pm

In an effort to find out what the calling frequencies are for JT65A on the various bands I have come up with the following list.
At the risk of repeating the frequency suffix all are listed in Mhz.
1.805
1.838
3.576
7.036
7.039 Europe
7.076 USA
10.139
14.076
18.102
21.076
24.920
28.076
50.076
50.160
50.260
144.076
144.116
144.160
The mode in every case is USB
On 70cm and up it does not appear clear so I am assuming that they might be
432.076 USB
1296.076 USB
and so on as we go up the bands......
How accurate is my list as I have noticed on various loggers many other different calling frequencies and even LSB being used as the mode?
Why are three calling frequencies listed for 6 and 2 metres?
Appreciate any corrections or additions to the list.

Mike

Digital terrestrial calling freq in Australia is 144.225 USB

Meteor digital is 144.230 USB

And so on 432.225, 1296.225. (cant really use meteors over 2m band)

JT65 is not really designed for HF but would probably still work.

Have you checked the band plan ?? http://www.wia.org.au/members/bandplans/data/

Thanks Leigh
Yes I had looked at the WIA Data plans and felt that they were too general and was looking for specific calling frequencies like the ones that you gave.
I had left out the Meteor Scatter frequencies as I felt that PSK441 (I think?) and not JT65 was used for MS.
Have noticed that JT65 is used on 80 and 40M quite a lot by US stations with low power and efficient but simple antennas.
Will add what you have indicated and see what else comes up?

As you probably know, JT65a is part of the WSJT software package. Thus contained within is also JT65b JT65c. The majority of stations looking for 2m and above DX (in VK at least) recognise WSJT as the most widely used software package.

144.225 is generally recognised as the terrestrial calling freq for digital modes (JT65).

The reason I mentioned meteor scatter was because the other mode in WSJT is FSK441 which is what is generally used in VK also for meteor sessions. The recognised frequency is 144.230 for digital meteor scatter.

Just basically expanded on my first post.

Interesting to hear your comment about 80 & 40m WSJT operations.

Bandplans have no meaning if you are not a member of the WIA.

JT65 was designed for use on meteor scatter on 6M, so try not to interfere with the DXers on 50.160. better to use 50.230 and up.

JT65 was in no way designed for meteor scatter, and will not work for meteor scatter.
Your possibly thinking of JT6M.
