I have been playing with a new Triquint ULNA device (TQP3M9036). It
Shows a lot of promise. It is like a MAR or MSA device in that it is
50ohm in and out. and has a claimed NF about .4db nf ( their numbers).
I have built several pramps to test them and have gotten even better
than they claim and they cover 50-1296 with ease and NF is .4ish or
below. The S11 and S22 are both great and the OIP3 is +35db also
...very nice device. It has great promise as a good terrestrial LNA.
Preamps are foolproof to build and would cost under $50 if all the best
quality parts are used.
Just for information only ...

Hi all,
I also missed a lot of sleeping as most of you ;-)
Made 19 analog qso's during those long two nights. Got a ssb contact
with PI9CAM when they tx with 50 watts or less. Nice!
Spent a lot of time looking for more stations, but maybe low activity
during my window.
Additionally made 9 jt qso's, 6 of them new contacts. Some of them could
be worked in cw as well.
Had some probs with defective contacts of my control cables and lost a
preamp. But no matter it was really funny.
Will not party in the contest because of the ARRL rules.
Hope to work you soon!

Hello Microwavers
We had a successful demonstration of 3 cm EME at the Microwave Update
Conference in St. Louis, MO on Oct 13, 14 and 15. I was located in EM48ss in
the hotel parking lot. The antenna was a 1 m offset fed dish made by
Winegard. Power was provided by a GaN device delivering 30 watts to the
feed. I used a KX-3 IF and DEMI transverter locked to a 10 MHz Isotemp TCXO.
I was not able to take advantage of measuring moon noise as a pointing
assistance as there was a local beacon up the band that was getting into my
GR-1216 noise meter. I plan to look into better ways of measuring moon noise
over narrower bandwidths ...However I drug out the compass and was able to
get reasonably close on azimuth and when we started hearing stations we
could easily optimize the dish and establish a new azimuth reference. The
theoretical 3 dB beamwidth of the 1 m dish at 10 GHz is 2.2 degrees. My dish
mount is calibrated in 1 degree increments making it easy to update once we
find the moon. Elevation readout was provided by a Sears digital level
placed on the offset dish feed support. Based on prior sun noise
measurements, I determined that the arm angle was 3 degrees below the actual
pointing angle of the dish. I requested that other stations who wished to
call me do the mutual Doppler correction on both receive and transmit so
that I could receive and transmit on 10368.050 MHz.
On the first moon rise, we did work on JT-4F G3WDG at 2257Z, OZ1LPR at 2305Z
and OK1KIR at 0042Z, We attempted contact with K5GW on cw but it was
confirmed later that Gerald had some tracking program issues and we gave up
for the night. The attendees were able to copy K5GW calling us on cw so that
provided a good demo to the guys. The tones from the other 3 stations were
also heard in the loudspeaker. so despite the fact that we had to manually
(with some luck) keep it on the moon without the help of moon noise, we did
have success.
On the second night, we had a repeat QSO with G3WDG at 2342Z (thanks Charlie
as you confirmed we were on the moon) and WA3LBI at 0023Z. I then ran a sked
with K5GW with me doing the mutual Doppler correction on both receive and
transmit and we established contact by 0130Z. We then went back to CQing on
.050 hoping for further contacts. We were surprised and pleased to make a
contact with G4CBW at 0135Z who was only running a 1.5m dish. We finished
the evening with a nice contact with OK1CA.
Thank you to the stations we worked and my friends who helped me with setup
and teardown.73 de W5LUA 10/17/2016
As the VHF manager who organised the VHF theme at the RSGB convention I would like to publically thank Peter for another really inspiring talk.
Some 45 years ago as a young amateur I went to a talk by Peter on EME at a RSGB convention in West London. As a result of Peter's talk I was hooked on EME for life.
On Saturday, after Peter's talk, I was aproached by a young amateur in his early 20s who had never seen anything about EME before. As a result of Peter's talk, which focused on 5.7GHz EME, this young man told me that was what he really wanted to do in amateur radio. This is a story that many others in the UK will also recognise.
So Peter again, "thank you" - 52 years of EME and still inspiring newcomers.

My thanks to everyone who sent me pictures, notes etc for this talk It was well received and I understand that there will eventually be film of it and all the talks at the convention on you-tube. I wasnt able to use all the material but the support I received from you all in the 6cm community was terrific. Thankyou again.

Hi All,
I have for sale a PA for 23cm made by Marko LZ2US, using TH327.
The PA is practically unused and has never transmited. It was part of my project of setting up a 23cm eme station at my summer QTH but I have no time to be there at all but 1 week per year, so it was never completed. It is not worth having it there and never using it so i decided to give it a way.
Here are the specs:
RF DECK
Tube :TH 327
Freq :1296MHZ
Output : >2000 Wattas
Gain App. :9dB
Efficiency App. :32% linear Mode
Voltage :220-240 Volt
Size :65x33x30cm
Weight :45Kgs
POWER SUPPLY
Voltage :3 phase 380-405 VAC
Size :48x42x22cm
Weight :60Kgs
Will be delivered in a wooden box.
I am asking Euro 1,000 + shipping from Athens to anywhere you like, preferably within EU. If there is a good home for this nice PA, please email me direct.
Pictures are available upon request.
tnx

Hello Friends
Any of you have a FT 991 for radio. according to what I read it does not required an Interface for digital work which include WSJT X. It has a soundcard but where is the interface????
I am considering a mobile radio which I can carry around easily like a FT857 or a FT991.
Please give me your comments & suggestion off line.
Thank you very much
Serge VE1KG
Does anyone have firsthand experience with the
Behringer U-Phoria UMC404HD
http://www.sweetwater.com/store/detail/UMC404HD
I've been looking for a replacement for my Delta 44 that will work with
a 64 bit system. Found this one and it looks too good to be true.
Thanks & 73,

Hello all 24GHz lunatics !
OK1KIR proposes to held 24G AW on Sat/Sun 12.-13.11.2016.
We will be active the both Moon-passes and available on HB9Q logger.
There was already a long time no 24 GHz EME QSO mentioned, so we think that all 24GHz equipments round the world desire to wake up.
Proposed weekend founds Moon close to perigee (dgrd only a few tens of dB) with quite low spreading. Moon declination will be in its middle range and growing.
We think that weekend proposed is better than working days also suggested by JAs. The weekend after (19.-20.11.) brings collision with the second part of ARRL contest. Furthermore also spreading and dgrd will be much higher together with declination at maximum. We are not able to seriously predict the WX around the globe, but it looks acceptable at least nowadays.
Let us now, please, if you suppose to participate to arrange proper operation plans.
