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,
referring to advise by IK1UWL sent on moon-net some days ago, I inform
you that as recommended by IARU Reg.1 the participation of multi
operator and portable stations is not recommended
*"COVID-19 - IARU R1 asks national societies to reconsider their
**field days and multi-operator contests for the next few months of 2020".*
73' Manager Contest - Enrico I5WBE
Dear EME friends, next weekend there is the Italian ARI EME Contest.
Classification in this contest differs from the others, since for each
band there are multiple categories, correlated to antenna dimensions:
Big guns battle with other big guns, medium stations battle between each
other, same for small stations. And Italian stations are multipliers,
please contact us. The rules are on:

I recently received this SA, but found the YTO is malfunction.
Searching the net I only found expensive replacement on ebay.
Also found that Luis, CT1DMK repaired those YTO by replacing the transistor.
Tried to reach Luis, but got no response sofar.
I have relation who can do the bonding for me if I can get such transistor.
Alternatively I came across an Avantek YO94-1201 YTO, which covers the required frequency range, but I cannot find any further connection information and details.
I hope that there is more information which can led me to repair the Spectrum Analyser.
Thanks in advance for any help.
