I have been trying to monitor EME transmissions when the moon is
overhead in the central USA. It seems the activity stops when the
european stations lose the moon and before the western us stations gain
it. Is there much activity when the moon is over the central US? I would
like to check my 144 and 433 setups using several radios with and
without preamps and see if a Nooelec dongle will work. But the activity
on the www.chris.org/cgi-bin/jt65emeA site just seems to stop about the
time the moon reaches 33 degrees or better in central US.
I have a 2x10el 144 setup and a 2x15el 432 setup i would like to test.
the 432 is portable but there seems to be little 432 usage in central US.

Hi ALL
Jean, F1RJ sent us an e-mail with his concern, that on May 30th the moon and
sun will be at times from some places extremely, obviously too, close to
the moon. Jean is right, so we decided to postpone our 13cm activity by
24h, which takes care of the problem (many thanks Jean!). Sorry for that
guys it is better to correct an error then just try to ignore or deny it!
Our 13cm (23xx MHZ) schedule changes from May 30th to May 31st. Here the new
activity details:
31. May (Tuesday)
2320.100 Q65-60C TK/HB9CRQ 1st RX on own echo, 04.30z until 15.00z
2304.100 (during W/VE window, QSY will be announced on HB9Q 23xx logger)
2301.990 and 2400.100 (on request only, please send e-mail to dan(a)hb9q.ch)
All other information and activity dates remain unchanged.
We are very much looking forward to work you from TK!
Vy 73, Dan HB9Q
Here some more details of our DXpedition (already posted 6th of April):
Well travel by car and ferry to Corsica and stay there for 10 days, doing
some sightseeing/vacation and of course EME on 1296, 23xx, 5760 and 10xxx
MHz. Sorry, but 3400 MHz is not allocated to amateur radio in TK.
We have already booked the house and the ferry tickets from Livorno to
Bastia and back. Team members will be again Sam HB9COG, Dan HB9CRQ and Sue
Dans YL.
Our QTH is a nice little house on the southwest side of the island in
JN41ml, directly at the beach. Since our QTH is located in a bay open to the
east our MR should be perfect! For MS we expect some 20° to max 30°
elevation due to the mountains and some trees (we will only know exactly
once we are there). But in anyway, we should have good enough MS to work the
US-Westcoast. Due to the fact that many, if not most of you, already have
worked TK on 1296 and 23xx 10 years ago and the fact that we will be,
unfortunately, in the same QTH-locator (JN41) as DL1YMK was, we will be QRV
only 1 moon-pass per band.
Here our operation schedule:
27. May (Friday)
5760.100 Q65-60D TK/HB9CRQ 1st CFOM, 02.30z until 12.30z
28. May (Saturday)
10368.150 Q65-60D TK/HB9CRQ 1st CFOM , 03.00z until 13.00z
10450.150 1st (on request only, please send e-mail to dan(a)hb9q.ch), QSY will
be announced on HB9Q 10xxx logger
29. May (Sunday)
1296.100 Q65-60C TK/HB9CRQ 1st RX on own echo, 03.15z until 13.30z
30. May (Monday) postponed to
31. May (Tuesday)
2320.100 Q65-60C TK/HB9CRQ 1st RX on own echo, 04.30z until 15.00z
2304.100 (during W/VE window, QSY will be announced on HB9Q 23xx logger)
2301.990 and 2400.100 (on request only, please send e-mail to dan(a)hb9q.ch
<mailto:dan@hb9q.ch> )
CW: As always, we will work CW on all bands. However only with big-enough
stations and after the pile-up on Q65 is worked.
Equipment (as always):
1.5m dish 1x2mm mesh, homemade automatic az/el control
1296: 100W at feed, circular, preamp at horn
23xx: 90W at feed, circular, preamp at horn
5760: 80W at feed, circular, preamp at horn
10xxx: 50W at feed, v-pol, preamp at horn
We will be using WSJT-X 2.5.4. On 23 and 13cm we use Q65-60C with Doppler
Control (Own Echo, in other words we listen on our own echo). On 6 and 3cm
we will be using Q65-60D (if necessary JT4F) including Doppler Control
(Constant Frequency On Moon and if necessary Full Doppler to DX Grid).
Hopefully more people take advantage of automated Doppler control.
Especially on 6 and 3cm it is a MUST for successful QRP operations.
Well have internet access. During our activities well be stand-by on the
HB9Q band loggers. We also will check our e-mails several times a day.
How big needs your station to be to work us?
On 23cm 2m dish and 150W at the feed
On 13cm 2m dish and 100W at the feed
On 6cm 1.5m dish and 80W at the feed
On 3cm 0.75m solid dish with 60W at the feed

I am in the process of rebuilding a 7 metre dish that I hope to use on 70cm. The dish has 24 steel ribs that I will cover with mesh. Originally the dish feed was supported by 4 steel pipes from the rim of the dish. I think this is a bad idea partly do to blockage but also because the rim is not the strongest part of the dish.
I am planning on either running four (preferably non-conductive) supports from a stronger existing 3.5 metre diameter ring that sits behind the dish, or a single supporting pipe (probably with non conductive guys) up from the centre of the dish.
Even with non-conductive supports, one of the supports will have to carry the TX and RX coaxes and I assume this will cause some blockage, so I am thinking the single support carrying the coaxes right up through the centre of the feed is preferable. However I have not seen much in the way of discussion of feed designs with a central supporting pipe. I have a 3 metre dish I have used with this method with success but this was only a 25mm support pipe and I will have to have something larger on the 7 metre dish. I would be interested in ideas others have and any references to information on this topic.

David
Thank you for all the comments. WSJT-X and MAP65 were closed but something may remain open in the background according to what I see in Task Manager.
I closed the PC, restarted and now the installation went without problems. WSJT-X opens fine but
MAP65 still flashes and goes away.
I worked on my sound card and it may have affected the drivers expected in MAP65. Is there a configuration file that I can fix so that MAP65 opens instead of flashing and going away?

All set up on a cliff top site for 2300z moonrise from DM57oj.
Hoping for plenty of Interest to make the effort worthwhile.
See you on the HB9Q logger.

I just upgraded from WSJT-X 2.5.0 to 2.5.4
During instillation I got several messages like the one at the end, I clicked 'Ignore" and the program seem to install fine and it opens and seem to work,
But when I try to open MAP65 it flashes and closes. It used to work fine before the upgrade.Any suggestions to make both programs work properly again?
Thank you.
