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 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.

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.
Hermann, DL2NUD, asked me to inform the U/SHF community as follows:
Uwe and Hermann plan to arrive (with their mobile-home) early evening of
21.4.2018 in Z6 Kosovo. They have to drive down almost to the SV border for
safety reasons. As soon as they arrive they will start to set-up the
stations. They hope to be QRV early afternoon (probably not for MR!) of
Hermann will be QRV as follows:
22.4. and 23.4. 1296.100 1st JT65c listening on own echo
24.4. 2320.100 1st JT65c listening on own echo
(2304.100 on request)
25.4. 3400.100 1st JT65c listening on own echo
26.4. 5760.100 1st JT65c (I recommended JT4F) listening
on own echo
27.4. 10368.100 1st JT4F listening on own echo
No CW, sorry!
On 28.4. they have to pack-up and depart for the 2000+km drive back home.
He hopes to have internet access. If he does he will be stand-by on the HB9Q
loggers for last minute information. Exact grid will be announced once they
arrive at the QTH.
Hermann is looking forward to work you and sends his best regards!
Good luck to all!

I am setting up a Spid RAS az/el HR unit and an MD-02 controller.
So far I have managed to power both motors and receive sensor information in the MD-02.
My question is as follows:
I want to communicate from the PC to the MD-02, the information I have says I need a program MD01DDE.exe, however I cannot find this program, RFdesigns have a program MD01DDE.ex_ but how do I make that into an exe program the PC can use?.
Alternatively can anyone advise me on how to have the PC communicate with the MD-02 and what program should I use to control the Spid. I have PSTrotator az/el (registered version) I just need it to talk to the controller, or what else should I use.

The new SPID rotator I've bought for my 23cm system is drivin' me mad.
It's the rather new SPX-03. Thats a mechanically new design but with the
former hall sensors, software, controllers etc..
None of the several manuals that came with the system fits to the new
one exactly, so it's damned puzzle to dig out what is right or wrong.
After three days of investigation I finally made the thing turn left or
right or up and down even so the counters and hall sensors are still
completely nuts. Counting backwards when moving up, showing negative
values when moving clockwards...and so on.
Sometimes USB works, sometimes not. He can talk to the factory software
(so called software...) from time to time but never to PST rotator by
YO3DMU. And yes, I tried several different computers, even an old XP
machine and all kind of drivers.
I guess the internal memory has gone mad but I couldn't find a way to
factory reset the system (MD-02 controller). There's nothing in the
manuals, nothing online.
Does anybody know how the completely reset the controller? Please?
