Hi Peter,
very well, you touched everything, so I have nothing to add to.
Looking for another "insane" beacon power from you on 6cm !
GL and 73,
Vlada for OK1KIR

Hi Vlada I found the conditions quite good I had roaring echo during the weekend.
I have also given the CP/LIN some thoughts and I get by using V pol and twist in case of need. Problem is no one get their CP Feeds near the performance of Lin feeds. There are additional losses in the CP feeds. Furthermore when one design a feed it is almost not fitting 100% illumination wise. Specially in Offset dishes that can be felt. Also dimensions are quite critical on 3cm making a good Circular Feed.
I would need a waveguide Feed for Andrew/channelmaster dish.
I am sure it will be hard to get all to agree on the topic.
Agreed power is insane at JLW and at my Station. Well my TWTA is a Class A TWT and does like making max power out in the feed. Otherwise it is just dissipated in the TWT. It draws 3000W from the 230V when PTT. It delives around 750W on the flange but big loss in feeder system.
Why alligator power ???. Well it makes everybody able to hear a signal from the moon same as the Beacon but only better as there Is actually a person behind.
I try to infect as many as possible to this challenging part of our hobby. Hearing a signal from the moon makes them want more.
Even my own kids are very amazed when I let them say a few words and hear them back from the Moon :o).
Vlada it is stations like you that makes the band a success as it is always possible to work you.
By the way soon I be QROO on 5.7Ghz also I just got the Waveguide feeder so will make 500W where around 300W will hit my Feed horn that actually is CP :O)
Have a nice day both of you.

Hi Dominique,
first sincere congrats to 1st CW 3cm QSO.
However something still to think about as the both OZ1LPR and SP6JLW have huge TX power.
Have you ever found ours 50W signal during the contest ?
FYI, we made 32 CW QSOs.
E.g. we made also random CW QSO with OK2AQ with 1.2m dish and similar power (close to 50W at max) at spread of 120Hz, but with linear polarisation !
Seems, these 3dB is terrible difference in real ether !
Probably, we shall live with LP vs CP troubles for some years and for many it is not as easy to swap it.

Hello All
Yesterday I wkd my 1st. 3cm EME QSO withOZ1LPR. It took almost 45 minutes to complete due to my small signal. Later I had another chance with SP6JLW, - same proceedure taking 30 minutes.. Easy copy at HB9BBD.No chatroom arrangement or internet stuff, real EME in CW.Thank you guys for this great fun!
Rig at HB9BBD: 1M offset dish, CIRCULAR POL, 50W, home made LNA 0.65dB NF.
73 HB9BBD, Dominique

Rein,
The mailing address for Gorge Hylinski is:
/Georg Hylinski/. Keplerstrasse 6. 71034 Boeblingen. Germany
His email address should still be good in QRZ.com
I use his HH-12 12-bit encoders and they are excellent.

Sked arranged with Arunas- LY2IJ wasn't successfull (never saw him
with MAP65 + adaptive pol Rx). But was successful with:
ZS6JON -23
F4DJK -21
UX5UL -18
I copied two sequences calls from DJ2TX but never saw his trace afterward.
QRT 17900utc
I will be pulling the cables to the 2m array soon this summer for
house construction that is planned, so will soon go QRT for 2-3
months. 6m cables will be pulled within two days for landscaping
work and to extend tower and add 2nd yagi; est late August
QRV. 23-cm is QRT due to az-el display problems but may be first
band reactivated if I am successful in fixing the very-dated
indicator. Hoping to have three bands QRV for Oct. ARRL EME WE.

Hello Radio Friends
I build a little interface using a MAX232 16p IC to get CAT control to my FT847, but every time I try to start JTDX I''ve got the massage Rig Failure In details i see: Hamlib error: Communication timed out while getting current VFO frequency
So far I did some troubleshooting:
Sure the USB to Serial converter is working 100% ( real FTDI chip ), also tried a PC with a "real" serial port
I tried several settings of the compoort of the Computer / FT847 and JTDX , tried 4800 baud what was advised on several sites ( also tried 9600 and 57600 baud )
The connection to the FT847 is the DATA port , 3,5mm stereo jack on the backpanel
For PTT and Audio i do use the 8p microphone connector
PTT and Audio interface was already working for many years with WSJT ( used for MS and EME )
At this moment I use a little external 5volt power supply to feed the MAX232 IC.
Who can give me a hint to get this working , what do I overlook ?? forgot a setiing somewhere ??
All ideas are welcome ...or maybe you have a same kind of interface and want to share the schematic diagram with me ???

I have two old French coax relays Radiall R554722418. They use 12V DC and
are rated up to 2 GHz but I can't find on the WEB any specs or at least
information of the maximum power they can handle.
Any idea? Thanks.

This contest has turned out very badly for me. I finished my 3 CM rig last
Sunday, and managed to work HB9Q on Tuesday.
I was very excited for the contest to arrive. Saturday morning I put the
dish on the moon and began hearing stations. OF2DG, OK1KIR, G3WDG, HB9Q,
SP6JLW, and others that I didn't immediately recognize were solid copy on my
4 GHz dish. I began calling with no results. After I lost Europe, I pulled
the equipment from the dish and put it on the bench. The 25 Watts that I had
earlier was now 2 Watts.
Upon testing, my amp still draws the specified current, so I am hopeful that
it can be restored, but that has ended my contest hopes.
