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.

I stumbled on this site and discovered interresting things.
2m Dual-RX (Special RX converter for 2m adaptive (EME) receiving)
http://www.ha1ya.hu/htmkepek/dual_rx.htm
ME2-XP 2m dual RX (EME) transverter (The first dual RX color display
transverter on the World!)
http://www.ha1ya.hu/htmkepek/me2xp_spec.htm
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 -
configuration).

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
Hello everyone:
I seek to add a camera to the center of my EME array to know when it¹s
on/off the moon.
Requirements:
1. wired camera (not wireless nor Bluetooth),
2. CCTV type is OK if available
3. All weather capable 20 deg F through 110 deg. F
4. Reliable all the time
5. Monochromatic or color (either one) is OK
I recall there was some detail about viewing the moon that a certain focal
length (lens) is best and I¹d welcome (please) camera recommendations
available today.
Questions:
What specific camera manufacturer and model do you recommend?
What specific monitor (manufacturer and model) recommended?
What cable type is required? (impedance, number of conductors and gauge
for 150 foot or 48 meter length)
Thank you; very 73,
Dave KJ9I

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:

Hi all,
Still plugging away at my little pistol EME station. I was out rerouting
the hardline I was planning to use for feeding my array. I discovered
that I had a barrel connector splice in it so I was a bit disappointed.
I dug out another piece of heliax that will now make the run without a
splice. I will use the piece with the splice for my receive cable now. I
assume the splice in my receive feedline will make very little difference.
Im curoius how much difference there is in N connectors and the standard
UHF connectors. Is it all that important as to what I should try to be
using? I am more concerned with loss than I am with the ability to shed
water. I have never had an issue with uhf connectors and water getting
into them. My new piece of cable I had does not have any fittings on it
so I will have to buy them anyway. My receive feedline, since it was
used to feed a hf vertical at one point, has the standard uhf
connectors. I assume I can just use it that way. As my stuff is
dribbling in, Im finding that connectors on the transverter, sequencer,
and the preamp have combinations of different styles of connectors as
well. I think it would be wise to try to stay away from adapters as much
as I can. These look to be a bit lossy I would assume. My phasing
harness will have N connectors since that is what is on the baluns. I
will have a number of jumpers eventually. Im just trying to get every
little bit of power output as I can since Im just a little guy. Any
thoughts?
