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.

I’m ready on 6cm with the same dish I’m using on 3cm.
Despite the strong local 5 GHz WiFi noise, had a nice 579/569 first QSO with this setup today with HB9Q, thank you Dan !
Setup is a 3.7m dish and 60W at CP feeder.
I can be QRV on 6cm or 3cm most of the days, skeds and tests are very welcome, as usual.
qrv 70cm, 33cm, 23cm, 13cm, 9cm, 6cm and 3cm.
I stumbled on this site and discovered interresting things.
2m Dual-RX (Special RX converter for 2m adaptive (EME) receiving)
ME2-XP 2m dual RX (EME) transverter (The first dual RX color display
transverter on the World!)
Does anyone have feedback from one of these 2 devices?
It sounds interesting but I'm looking for someone who has this kind of
device to exchange feedback, especially with the use of MAP65 (setup -

For 10Ghz only one preamp is available and we will close further production after delivering more then 100 pcs.
We expect a crowed band in the coming time,hi.
We are currently preparingthe first batch of a super LNA for 24Ghz with NF: 1.1dB
Furthemore we would like feedback for the design and production of an 24Ghz SSPA.
Design goal is: 10Watt rf out, Vdc: 15Vd and WG connections.We will design against a reasonable price but need your feedback.
Thanks in advance,

Hello to all interested in the 222 band.....I still need several states
for 222 WAS. I have grouped them into two "groups"....east and west
The east group consists of KY, WI, MD, DE, ME, RI, VT, and CT. Of this
group, KY and WI could easily be worked via meteor scatter, IF I can
find someone to run with in those states. So if you know someone that
might help, please try to get us together. MD and DE are also workable
from here on meteors, but those states are in the "long haul" category.
In other words, they are both at almost maximum distances. The rest are
probably reachable via EME.
The western group consists of NV, MT, OR, WA, and WY. Of course, there
is always HI, but everyone is just waiting for Bill-ND0B to move there
with his Lunar-Links and FB antennas. None of he above states are
reachable via meteor scatter, so EME will have to be used.
On meteor scatter, I am running 2 x 23el at 135ft and about 1300W. On
222 EME, I am running 8 x 222XP40s with full steering and a tower
mounted cavity preamp. In the last week, I have worked two new
states....UT thanks Mike-K7ULS and MN thanks Mike-W0VTT and AC0RA-Wyatt.
If anyone can help me with my 222 WAS, please contact me. You don't
have to have elevation to work me, just a good tropo station with some
power. We can run on your rising moon(stations to the west of me) or
your setting moon(stations to the east of me).
David-N9HF is also trying hard to finish out his 222 WAS, so if you are
active on 222 you might contact him to see if he needs your state.

Phone is 409-787-3830 if you want to talk about all this....
This is not EME related , but some advise appreciated. We are starting to
experience transequatorial propagation and when it get strong the flutter
on frequency tones get to the point of no decode in FT8. What digital mode
besides cw... will perform better on this situation? Sort like strong
aurora reflection too.

The last of the three 2019 ARRL EME Contest weekends is fast approaching
ARRL has activated the web app for uploading your Cabrillo File log at
Remember, if you participate(d) in more than one of the three 2019 ARRL EME
Contest weekends, this Cabrillo file must contain all of your contest QSOs
(from all weekends you were active).
Do not upload a separate file for each weekend, as the last final/last you
upload will be the only data that the contest will see from you.
If you participated in the first and/or second ARRL EME Contest weekends,
and do NOT intend to operate in the 3rd weekend in November, you can upload
your contest entry at any time.
And of course, paper entrants can mail their handwritten logs with summary
sheet to ARRL within 30 days after the last contest weekend.
Please contact me with any questions.
Thanks for participating!
