A few years ago I used a RF Space module to tap the IF from Flex while
using Demi transverter to run Map and Jt at the sme time on same computer
using multipule screens. It was not a very fast machine but worked well.
Tap was a "T" bnc connector. I might make mention that Q65 contest mode
displays linear decodable signals in the bandpass somewhat like Map.

Why not use standard “EU” exchange procedure for the EU window, and the NA procedure, which is invalid for awards in most countries other than the USA, for the NA window? Then everybody happy and no more squabbling.

This is a reminder that Today, Friday 24th March is the 13cm SSB Funtest, rules in Dec 2022 432 and above NL.
The 25th/26th March is the DUBUS-REF 13cm SSB/CW contest. Rules are at http://www.marsport.org.uk/dubus/EMEContest2023new.pdf
Weather permitting I will be QRV for both events, 6m dish 250W at feed. (At present it is too windy but I hope it might ease later today)

Hi All.
I've been monitoring the JT65 N0UK logger and I find the conversation
troubling.
It seems that one or more stations are using non-standard EME procedures
and there is some disagreement over that.
One of the operators may even be using his own chat to clarify aspects of
the QSO according to what I read on the logger.
A valid QSO stands on its own and does not need outside clarification.
Hasn't the format of EME procedure been established world-wide for decades
now?
Maybe some shortcuts are acceptable in the US, but can we really afford to
alienate ourselves from the rest of the world?
When the moon goes down in Europe we are hard pressed to find a QSO. I for
one would certainly hate to be blacklisted by the rest of the world.
I find myself in agreement with the Europeans on this. We should all pursue
valid QSO's that the whole world can agree on.
Maybe we should not count on using tricks in an attempt to make a
questionable mode (at least on 2 meters) work better than more established
reliable modes like JT65b which gives me fairly consistent decodes down to
-30db when using WSJTX. I know some people think Q65 is better, but so far
I just am not
seeing it. Here a -30db decode on Q65 is much more rare. I watched a Q65
station for over an hour and finally got a single decode at -28db,
otherwise no decode at all much of the time. Other times he was much
stronger than that. I have no trouble getting frequent decodes at -30db
using JT65b and can see short hand signals on the waterfall even weaker. I
can't say that for Q65 which I believe is the main reason for some
stations now using non-standard EME procedural formats.
I do EME because it is hard.

Hi All.
This is about 30 minutes of monitoring 144.144 on March 23, 2023 during the
CY0S
Dxpedition. Each radio was fed from the vertical array of 4xUWA12 yagis.
Horizontal is currently blown up. I used vertical for TX and vertical for
RX.
Excess noise was about +4db at this high elevation (57deg). Both radios
feed
their own instance of WSTX v2.6.1 by K1JT. The mode was Q65-60a NA contest
mode.
Deep Decode,Enable averaging, Clear after decode. CY0S was selected with
50hz
tolerance. CY0S,FN93 was in the DX Call and DX Grid boxes. Note the
variation
in decode levels reported even though they are from an identical signal
source.
At 1841 a single decode was from W8KEN at -31db on the 706 but at the same
time
was -29db on the 736r. Something must have gone wrong on the 706 side.
Notice the
high number of nil decodes on the 706 while the 736 had decodes in the -20
to -26
db range. The 736 has a superior noise blanker and a flatter passband. I
don't think
there was pulse noise at the time. Sometimes the 706 gave better decodes.
15 times the 736 gave better decodes. 11 times the 706 gave better decodes.
3 times they were identical. In no case did the 736 miss a decode that the
706 got.
10 times the 706 missed decodes that the 736 got. There were probably times
that
the 706 could have reported -31 or -32db but got nil instead. Only one time
was
there a decode below -30 and it was -29 on the 736 at the same time. At
other operating
times there were instances of -31 and -32db on CY0S but I did not save that
data.
I did not save the Map65 data. It was nearly worthless with WSJTX decoding
about 3 times
more data. My QSO did not decode on Map65 and if I only had Map65, my QSO
would have failed.
There may be some value in redundancy and using WSJTX. There are some
differences in reported
DT but they do not explain differences in decode levels. This is a small
data sample so
conclusions based on this small sample may be wrong.

Dear friends,
I am looking for a pair of coaxial SPST relays with SC connectors.
Something like these examples:
I can offer in trade a pair of Used-Excellent-Guaranteed Dow-Key 402A-280132
high-power relays with Type N connectors (28V, failsafe, w/indicators):
I can also pay money.
Thanks-
Mike, W9IP
Can someone help me to get a working e-mail address from Fabrizio IK4VYX?
I would like to contact him to obtain a registration code for DXTelnet.

Looking for circuit diagrams for the control and RF boards of the Tajfun
1000 70cm PA. Joe and I lost it without any alarms during WSJT-X tune up.
We are reluctant to just replace the failed LDMOS without trying to
determine the cause of this failure. Any suggestions of what to look for or
test as well as the circuit diagrams would be appreciated.
