locked JT65 Setup for EME #JT65


Frank Ousley
 

I am new to EME and I have been having no results on the decodes. Here is what I get.
2027 -30 4.6 2107 ## 0123456789ABC OOO d*3
2030 -27 -1.5 2056 ## 0123456789ABC OOO d92
2040 -25 4.2 2063 ## 0123456789ABC OOO d32
2043 -1 3.7 2040 #* 0123456789ABC d62
2046 -23 4.2 2058 ## 0123456789ABC OOO d43

I never decode any call signs. Any ideas?

I don't do EME myself, but several friends do. They are using one of the flavors of Q65. First questions -- what band(s), what power, what antennas? In general, you need a lot of both. The higher you go in frequency, the easier it is to have more antenna. Also you've got to be pointing them in the right directions at the right time(s).

Hi Frank

Are you seeing any evidence of signals on the waterfall?

Is your PC time correct?

Are the stations you are monitoring using JT65 or Q65?

None of the DT values you have seen would be valid for EME signals. If
your PC time is correct, you need to see values in the region of 2.5s.

Hi Frank,
at what precise frequency are you trying to listen ?
i f you are on a random frequency is almost impossible that you receive anything except you are very very luck :-)
First of also set mode to JT65B that is still the most common mode in 2m EME and go to link https://www.chris.org/cgi-bin/jt65emeA to see who are active at that moment and try to listen him at his QRG.

Charles,
Yes I thought the same thing about the time. I have Diemsion4 as my time since. But if I switch to like FT8 or WSPR on the same computer and radio the times are correct.

I am on the default freq. 144.120.I do have it on JT65B. I followed this setup guide.

Later today I will listen on the frequency with the active QSO are going on.

Hi Frank

I don't know much about 144MHz EME operating frequencies. While .120 may
be the default, it may or may not be be in use at any particular time.

I'm not sure what everyone on 144 uses for online chat, but this website
seems promising to see what activity is happening currently:


https://www.chris.org/cgi-bin/jt65emeA

The moon is moving to more southerly declinations at the moment, and will
be lower above the horizon in the northern hemisphere, so activity may drop
off for a week or two.

GL!

Don't forget about this website which shows whom is calling CQ on 144, 432, and 1296:

There's an active EME channel on Slack VHF-Chat, but it's all NA hams. There are some pretty sharp guys there, so it could be a good place for the original poster to sort out his issues. An invitation is needed to join, and always furnished on request. I can forward a request to the administrator of that group.

WSJT-X can be set to post reception reports to PSKReporter, and I think it might be a default (it's been a LONG time since I installed it, don't remember). Very useful in studying propagation, finding out if you're being heard and where.

An invitation would be appreciated.

As a followup to this post, I've been studying EME, and W7GJ's website was recommended to me. It is bigskyspaces.com and it contains a wealth of information, both tutorial and practical, about EME.

http://www.bigskyspaces.com/w7gj/20206mEME.ppt is a great tutorial about EME and its development over decades.

https://youtu.be/vOrCXifwAsM is a nearly 2-hour operating session on 6M EME demonstrating Q65-60A on 6M as he works well over a dozen stations in NA and EU. He shows how to interpret the wide display, how to respond to calls, and talks a lot about the advantages of Q65 over JT65.

The website includes a table listing "good" days for 6M EME based on relative positions of moon and earth with respect to each other and to noisy/quiet parts of the sky. There's a link to VE7BQH's tabulation of Yagis for VHF and UHF bands that displays their gain individually and in arrays. And many other resources.

Lance is one of the pioneers on EME, beginning 30+ years ago on CW. He was thrilled when K1JT introduced JT65, used it for years. He now uses Q65, most often the-60A variant. Both he and my friends who work a lot of EME also use Q65-60A.

I post this to offer a different viewpoint than the post by someone else in this or another recent thread saying that JT65A is the standard on EME. While JT65 still works, Q65 changed everything! Various doc files on the WSJT-X website explain why.

Hi Jim, thanks for telling the truth!
