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,
this is a reminder for the ARI EME Trophy 2019 Spring Section

I seek to add a camera to the center of my EME array to know when it¹s
on/off the moon.
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
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,
Latest News On the Current 2 m Band Allocation Discussion
As most of you probably are aware, for example from the email by John,
G4SWX, dated June 6th the French administration at short notice had handed
in a modified a proposal to WRC-19 preparatory groups at CEPT that WRC-19
should decide on feasibility studies for additional
Aeronautical-Mobile-Services(AMS) allocations in the range from 144 MHz to
Since I have some insight in this matter I would like to give you a short
information update on the situation.
If this proposal in its current version is endorsed at the next meeting of
the CEPT Conference Preparatory Group in August it is highly likely that it
will appear on the agendas of WRC-19 and WRC-23 where a final decision will
be made. At least 10 of the 48 CEPT countries have to be in favour of this
proposal while not more than 6 must be against this.
During the recent Meeting of the CEPT Project Team A in Prague this proposal
by France was being discussed for the first time. Only the German delegation
made it clear that they are against this proposal including 144-146 MHz.
The main reason for that little opposition might be that the 2 m band was
included in the revised version of that French proposal only few days before
the deadline for the Prague meeting. Consequently most other European
countries had no time for internal discussions let alone formulating their
IARU, being supported by regulatory experts of their member associations
(RSGB, DARC, VERON etc) is intensively working on executing their influence
within the current process and trying to keep the 2 m band as it is now. By
the way, the cost of this activities is covered by the funds resulting from
the contributions of the IARU member societies. So those who left their
county's amateur radio society should perhaps reconsider their decision.
Without the commitment and the funds the amateur radio community would have
little influence in that process, let alone could be present at the relevant
Most importantly, amateur radio should speak with a single voice only. So I
would like to ask everybody to refrain from using maybe good personal
contacts to your government or the EU. This would weaken our position and
take away power and vigour from the systematic approach by IARU and country
amateur radio societies. This particularly applies for online petitions in
the WWW.which by the way do not even base on a correct facts background.
