We operate 10GHz EME, mainly WSJT but occasionally CW at the moment, so
this is only one viewpoint.
All that is possible in some cases, and all that is needed, is an
exchange of Callsigns/Signal reports to prove a contact has been made.
All contacts are about the same distance. The mode used is a secondary
There are a wide variety of issues when considering EME from 6m to
24GHz+: signal strength, mode, libration, timing/skeds etc, so
requirements will be different for each.
Given the difficulty in putting together large stations, some form of
hierarchy in points in terms of bandwidth may be useful - eg SSB - CW -
Data. Do this by having separate sections if you like, but make it easy
to submit logs. All I want is to maximise the activity/chance of QSOs.
For most stations, it is not about winning. It is about having the
opportunity to have QSOs. You will get more entries if you keep the
Whether CW or Digimode, I value the signal strength exchange. Signal
reports are a vital part of the contact, both for interest, and knowing
at what rate to proceed. Trying to strip everything out of the exchange
to give the absolute minimum QSO time does not seem to me what EME is
about. It would be a very retrograde step if all contacts degenerated
into an exchange of 599 regardless, as on the HF bands.
It is useful to have both the signal report and Grid in Digimodes, as
they come "free" in WSJT. It also gives a hard copy of the exchange.
If CW exchanges don't have the Grid, that need not be a problem. ARRL
can work out the Grids/Country multipliers afterwards if necessary, when
the entries are received. It does not matter if I am not sure of the
score when sending the entry in.
The ARRL EME contest is a focus for worldwide activity. Two sessions per
band per year doesn't seem excessive, and is good for activity.
We have found the ARRL EME entry format a bit uncertain. It would help
if they specified more of the variables, eg time window for a contact,
what is actually required in the exchange, and that the location can be
sent in with the entry.

In the latest version of the WSJT-X the information in the
"Last TX" field (the lowest line of the main program window
on the left,) has disappeared. By default, it is set to Russian,
could this be the reason?

Happy New Year to everyone !!!
I still have my 3,4GHz 130W PA from DL2AM for sale.
It comes with input and output coaxial relais.
It's not surplus junk but one of DL2AM's masterpieces. Make a realistic
I will be very happy to try! I hope my antenna will move, now there is a lot of ice and snow. I will try to be active today 12/30/2022 after 12:00 UTC and tomorrow 12/31/2022. 5m dish and 600w

I have started to play around on the satellites and using the TS2000 satellite functions. The question is regarding the 67Hz tone when trying to use the FM satellites like A0-91 and the ISS. I am able to set up the frequencies, modes, and label the memories. However, there does not appear to be a way to add the 67Hz audio tone to the transmit frequency. In the memory mode, I try to add the tone by pressing the [func] and then the [tone#4] but the "T" does not appear on the display and unable to scroll through the various tones to add it. I can add tones to the usual non-satellite repeater settings. There is nothing in the manual that describes adding tones to satellite transmit freqs. Any help is welcome. Thanks, Rick K1DS
On December 30th through Jan 2nd the DVRA will activate W2T and W2P
Special Event Operations to commemorate the historic Battles of Trenton and
Princeton on several of the HF and EME Bands. Look for W2T, starting
tomorrow starting at 20 UTC on 2m EME. Watch the boards for frequencies
and additional times.
Amateur operators across the US -- and some across the globe -- make it a
point to work both W2T and W2P for the opportunity to receive the QSL cards
and to earn a certificate conferring a "Commission as a Lieutenant in the
Continental Army Signal Corps" as a beautiful piece of ham shack decor.
