Hi all, My friend SM4CHK Oscar have come across some nice stuff see below
MW dishes and links are available at JO69TH/SM4CHK. Complete list of it all

Is some one using the "U-PHORIA 404HD USB" sound card for EME?I work 70 cm but if you work on any other band any information would be useful.It has a control panel software and hardware knobs that show signal and clipping.I would like to see if some could share their experience in the proper settings.I use it with the IQ+ and MAP65.
Personally I would not reply on that request.
SPID never ever respond on requests for information, diagrams etc.
They even do not respond on all complains and bad behaviour of their
I am happy I have an active SPID reseller and service point. Feel sorry for
all that guys that have not.
Let SPID first respond on simple requests first before supplying them with

I have for sale a Stealth Microwave SM3437-43L -1Q 3.4GHz amplifier. It
is fitted with options 01, 06 and 13. The data sheet for the amplifier
is available via Google or email me. I don't know what the options are
but I suspect one is a heatsink as this example has a substantial
It is linear with an output of +43dBm (20watts). Gain is 50dB so it
needs well under 0dBm (1mW) of drive. Input and output connections are
SMA. I guess it would suit driving with one of the GHz SDRs such as
Pluto or a transverter.
It is ex equipment (WiFi Max) but in excellent condition. It is in the
shrink wrap packaging that it was supplied in when I bought it about 4
If you are interested email for a copy of the datasheet and photos.
Price is £100 plus postage. Sorry I will only post to a UK address.

We are very sorry to announce that we have to postpone once more our SV5 microwave DXpedition. Due to the Covid-19 situation we came to the conclusion that we better postpone it to May 2022.
End of next month we will publish all details about the 2022 DXpedition on our webpage www.hb9q.ch and on moon-net.

The rotor manufacturer SPID wrote to me the following request.

Mr. Staszek, could you put a question on the moon forum ??
Since I dealt with XY rotors, I need an algorithm (formula) for
converting AZ / EL coordinates to XY coordinates.
I need an algorithm, a formula to convert.
Please post such a query, maybe someone will answer or tell you where to
Now many follow LEO satellites and the XY rotors are the best for that.
I am looking for advice on the size of slew gear I could use for the
azimuth drive on my dish.. I have seen other articles and have been in
contact with Kinematics
in Houston.. After talking to them and sending info and drawings on what I
wanted to do, they got back to me and said they dont make a slew gear large
So I wanted to get some opinions from others here if possible.. What I
have is a 22 foot mesh dish supported in a tower type metal frame..There
are pixs on my QRZ page..I was going to have a roller system on top to
support the dish and frame weight, then a steady bearing or shim at the top
and half way down.. The slew gear would be at the bottom of course.. The
real only force on the slew gear then would be rotary torque or twist..
Now I have seen others with large kennedy dishes using a 15 inch slew
gear.. I wouldnt think I would need one that large but I know larger is
better sometimes... I would like to hear from others and their opinions and
experiences etc.. Thanks, Skip
My friend Joe WA8OGS and I have been building a portable 432MHz EME station
that we hope to try soon at our radio club-WC8VOA- and we are concerned that
in picking 432MHz we may have limited our chances of success. It took me a
while to find www.LiveCQ.EU <http://www.LiveCQ.EU> but I watched it over
the last weekend and while I saw some 432MHz EME activity in Europe, Russia,
Israel and Spain before the moon rose for me at EM79ui-Cincinnati, Ohio
USA-I didn't see any 432MHz EME North America or Asia activity. Is this
because we don't have big gun trackers in North America? I did see WZ8D who
is near me on 2Meters and I even heard him on my attic M2 eggbeaters
although I couldn't decode him.
Is there any other place that I should be looking for 432MHz EME activity
that we can hope to communicate with?

That is part of the "1300 Mc" module out of a Bird Wattmeter Tester.
The tester was a rack of modules for various bands. I have a photo of
the unit somewhere but I couldn't find it just yet. I cannibalized one
of those myself and used just the two tube cavity on 1296 for quite a
while. I never had any documentation on it. Here are some photos of
what I put together with it almost 20 years
I used this bias circuit: http://alaska.net/~ptt/2c39/BIAS.JPG I
built an input circuit for the two tube section and drove it directly
with a FT-736R (10w). I have more on that circuit somewhere, and I can
dig it up later if you want to try it. I was getting about 200 watts
out of it.

This weekend was fun with quite some stations fired up the station.
I worked 42 stations and 4 of them Italian generating multipliers. Good
activity from US stations.
I tried to get more CW contacts, but only 2 stations worked in CW.
It brings my total up to 196 points.
Conditions changed all the time. Both days at moonrise most signals were 90
On the Sunday moonrise I started later than planned because I got a
phonecall from the hospital
that they had Covid19 vaccines available and since I was on the waiting list
and could get it now.
So I started 30 minutes later than planned.
Some moments after sunset conditions were great and I was able to work some
This contest is fun and the time nearly perfect this weekend. Well done
