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’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.

Hi mooners,
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,
Jan PAoPLY
Dears EMEfans,
I invite you to send your log will be appreciated, also with only one
qso, end-time Monday June 18th.All format areaccepted, better if xls.

I am almost done with firmware for MABMPU simple controller. This is a potential replacement for DRO levels that can be expanded in the future to work with various popular EME trackers like RazTrak, DrzTrack, OE5JFL, F1EHN.
In order to use this setup, one MABMPU encoder board takes on role of the controller and reads the US Digital SEI bus encoders and displays the results on the LCD. This simple controller works with US Digital A2 and A2T encoders or MABMPU encoder board (using MAB25, MAB28, ETS25 or MPU9150 inclinometer).
Power (+12VDC) is provided to the encoders over the 6-wire CAT-3 cable from the MABMPU simple controller. In theory, the US Digital SEI bus can drive cables over 100m.
For those that already have a EME tracker which utilizes US Digital encoders, I have a version of the MABMPU LCD firmware that monitors the SEI encoder bus for encoder read position commands and simply displays the positions on the LCD display. In this configuration, the power to the MABMPU monitor is obtained from the SEI 6-wire bus.
Simple Controller:

Hello everyone. I am hoping these relays will be of use to you. I have
received requests for more relays since they sell out quickly. Below are
listings with URL's that show a picture or two. ANY orders outside of
the USA will require insurance. In the USA if you want additional
insurance you must tell me (flat rates provide $50). PayPal works well
with me. If you do request a relay(s) _please_ be prepared to pay for it
that day via PayPal.
1. (Quan 25) Charter (P/N-B7N-142102), SPDT, SMA, rated 13 GHz (but good
to 18 GHz per Charter Engineer I spoke with), 24-32 VDC coil, open ports
50-ohm terminated internally, min of 1 million contacts, min isolation
>90 dB @ 2 GHz, break before make, 200W (CW) at 1 GHz, (50-ohm
terminations 8W), latching with aux indicator contacts and what is super
about these is they have the low passive inter-modulation distortion
option (PIM = -110 dBc, 2-tone). $21/ea + shipping.

Hi all,
check out http://www.darkside.cz/eme.php
By the way I'll not take a part this time because of
IARU R1 UHF/SHF Contest. I'll be running
this UHF Contest with my club OK2A on 70/23/9/3cm.

Thanks to all who helped me in my quest to find some 2M antennas so now my attention turns to 432. Looking for a 500-1500W 432 amplifier. Can be tube or SS. Will consider homebrew. Photos are a must. Email direct to avoid reflector traffic.
