Hello!
Please help me test the new version of Q65 that I will be using during my upcoming 6m
EME DXpedition to 3B9! On Saturday, March 18, I plan to be QRV from 1400-2100Z on
144.110 calling CQ in the first sequence Q65-60A using NA VHF CONTEST MODE at an
offset of 1500 Hz. This time period includes the moonset in western EU as well as
moonrise in JA, ZL and the eastern half of VK. It is important to test the program in
as much of a "pileup situation" as I am able to create, to simulate the type of
activity encountered during a real VHF EME DXpedition. Please spread out (ideally
every 50 Hz), coordinating on the N0UK JT65 EME page. With my K3, I should be able to
see callers on offsets between 300 and 2700 Hz (please take your doppler shift into
account when picking an offset to start calling, and then stay there!).
Please download WSJTX v2.6.1 (or later version, if there is one by then) from the
following site:
https://sourceforge.net/projects/wsjt/
And then select the "SPECIAL OPERATING ACTIVITY" and "NA VHF" options
on the
"FILE/SETTINGS/ADVANCED" screen. Please set up the program as outlined on my
"SETUP
CHECKLIST" page below EXCEPT DO NOT ENABLE THE AVERAGE, since I will be changing my
messages frequently to reply to other callers:

Of particular interest at this point are the following improvements that K1JT has
recently made to the program I will be using on my end:
1. The Q65 decoder has been enhanced for better performance.
2. WSJT-X has new features designed to help manage a weak-signal pileup
situations such as those experienced by VHF EME DXpeditions. In NA Contest Mode,
messages exchange 4-character locators rather than signal reports. Decoder
"memory"
provides q3-level sensitivity for up to 40 callers decoded at least once in the past
24 hours, and for whom the Moon is still above the horizon.
What this means is that if I have successfully decoded a caller, I will see full
decodes from any subsequent transmissions detected from that caller, just as if I had
entered his call and grid into the DX CALL and DX GRID boxes for a one-on-one sked
using Q65-60A in WSJT-X v2.6.1. This is a HUGE advantage in EME pileup situations! I
will be saving all my .wav files for K1JT to further evaluate the actual on the air
tests.
In addition to the greater sensitivity of Q65-60A, using the NA CONTEST MODE is fast,
and should make it a great choice for 2m DXpeditions - especially as the moon is
rising and/or setting in different parts of the world and many stations are using
ground gain or losing common moon window at the same time! Please use RRR instead of
RR73, as it may take several sequences for me to be able to copy your final RRR and
complete the contact. Depending on the size of the pileup, after I receive your RRR,
I may send 73, or I may immediately reply to another caller. I am looking forward to
the tests on March 18, and hope as many of you as possible can get on and call me!
And of course, if you still need Montana or DN27 on 2m, this is a great opportunity
for a contact!
MNI MNI TNX! VY 73, Lance
