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.

Any of you have a FT 991 for radio. according to what I read it does not required an Interface for digital work which include WSJT X. It has a soundcard but where is the interface????
I am considering a mobile radio which I can carry around easily like a FT857 or a FT991.
Please give me your comments & suggestion off line.
Thank you very much
I have a plan
I would like to apply, but step py step for EME of new stations .... I wld
like apply 6m & 70cm & 23cm ... the question what the first band I start ?
from above I have just ft-2000d & ft857

Sri I made, at least a mistake, I send it again.
Very interesting answers. I come from Sats world, where the Doppler
is a serious issue and it is so quick that it is impossible to work
I will speak thinking in one carrier. Sats need to receive in only
one fix frequency (it is an active RX with a wideband), if the Sat
receives a carrier in this frequency then it will be repeated. The
signal TX from the Sat will be in one fix frequency. So people who
work Sats must correct its TX frequency (according with actual
Doppler) to reach the sat in its fix frequency, in the same way
because of the Sats will repeat this signal in a fix frequency, people
must correct its RX frequency (according with actual Doppler).
This way of dealing with Doppler is very interesting because NOBODY
KNOWS the Doppler of the other stations and nobody needs to know it,
we only need to know our own Doppler.
If we would use this agreement to EME communications we will always
speak about the frequency we hit the Moon, in other words the
frequency which the Moon hear us and repeat our signal.
The actual EME software shows us the Doppler as the sum of the Doppler
effects to reach the Moon and to receive the bounce signal, so Moon
will receive us at ½ Doppler announced, the other ½ effect will appear
after de bounce.
I will try to set a couple of examples.
1.- We will agree to hit the Moon in 1296.070. This is the frequency I
will announce in the log. In our software the dates will be:
The sign that the software shows will aplly to RX frequency and the
opposite to the TX frequency, and always ½ magnitude on each one.
Both of us must deal with Doppler, each one must do their task to hit
the moon in the agreed frequency and to receive the bounce according
our Doppler. Then we must set on our transceivers:
TX: 1296.070 -1.5KHz = 1296.0685MHz
RX: 1296.070 +1.5KHz= 1296.0715MHz
TX: 1296.070 +1.0KHz = 1299.071MHz
RX: 1296.070 -1.0KHz= 1296.069MHz
Each station who sees the post will act only according its own
Doppler. Don´t mind where is the DX station.
2.- In this case I see a signal in my receiver in 1296.070. What
kind of pair of frequencies I must set (I know nothing about the DX
station I have still decode nothing), I only know me own Doppler, and
it is +2KHz. I must hit the moon in the same frequency that my
TX: 1296.070 -1.0KHz = 1296.069MHz
RX: 1296.070 = 1296.070MHz
WE WILL NOT NEED TO KNOW NO MORE THAN OUR DATES.
I haven´t spoken about what frequencies will be the echoes (both
echoes), to make the understanding easy.
As a drawback we should change our habits, we should always use the
RIT as follow:
TX: The frequency we choose plus the opposite sign of Doppler and ½
RIT: the sign of our Doppler and ½ Doppler magnitude.
Although at first glance it seems not to be interesting in 144MHz but
we will always hit the target in whatever band, even in 144MHz.
Somebody can tell that they need a computer, to do JT65 of course, if
you do CW surely have a smart phone with the proper software to know
your own Doppler or you can print it before.
If I made some mistakes let me know.
It is my 2 cents.
For newcomers: The idea of activity weekends is to encourage activity on the higher microwave bands outside contest weekends. There are no restrictions... if you wish then use the logger, telephone, HF....and use any mode. It is not a contest. It enables everyone to make QSOs, test new equipment, feeds, preamps etc. Hopefully some of the big guns get on and provide signals for newcomers to look for.
Although co-incidence of lowest loss and high declination ( which we know gives the highest levels of activity) is slowly getting better year by year it is still hard to find good weekend dates not already committed.
My proposals for 2016 are June 11/12 9cm, July 30/31 3cm, August 27/28 6cm, and September 17/18 13cm
If anyone has any better suggestions, please make them. In past years these weekends have proved useful but there is no pressure to participate!

Im looking for our 10 GHz station for the following components, one of
WR90 twist 90°
WR90 bend 90° (as small as possible)
If you have surplus material to sell please let me know. Many thanks!
