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.

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!

We do have some complete build and tested OE5JFL standalone antenna
trackers left after our Heelweg meeting.
More info about this design see the site from Johannes:
If you are interested please contact me off list.
In case you want to reduce the shippingcosts: we can take them to Hamradio
in Friedrichshafen end june and to the EME conference in august in Venice.
All boards are build and tested. No MAB25 encoders enclosed but can be
ordered if you need them.
In case there are more demands then available boards we will prepare 10 new

A quick update on the next EME conference.
The conference, as announced, will be held at the BHR Hotel near Treviso.
The dates are confirmed: from 19th to 21th of august.
We reserved the whole hotel and conference center, that should be able to
accomodate the large part of the attendance, the others will be hosted in
other hotels nearby if necessary, at the same rates and with shuttles
between them (we will deal with the bookings).
The hotel is not far from Treviso airport, with free shuttles from it. This
choice was made because on Treviso airport land the majority of the low
We have a good number of sponsors, that will help us to ensure an
unforgettable stay, from I0JXX, that many of you already know, to the fine
CW paddles maker Mr. Begali (which has in store a mindblowing EME limited
edition paddle for you to see), along with Messi e Paoloni Cables, CSY &
Son (Yaesu) and others.
One thing is for sure, the final raffle will be something!
While we are still working on the website (we had a shortage of webmasters
lately...), we did manage to prepare a neat collateral program for the
ladies, that will be available for the audience as soon as the site will be
The good thing is, if you don't want to bother with looking for air
tickets, transfers and extensions for your trip (yes, there are some
proposals for those too), we will be able to deal with your necessities
directly. Since I own a Tour operator chances are that we will be able to
shave your ordinary travel costs.
We are working hard to host the opening of the conference in Venice, but
logistics is a true nightmare, and politics adds to the equation rendering
this part of the organization a total mess to deal with, but we don't give
If you have any questions, or you want to make a leap of faith and book
your flights well in advance, or you want to submit a paper for the
conference, drop me an email to iw3hvb(at)eme2016.org
I'll come back soon.
Enjoy the rest of the holiday season!
Remi says not to count on him before the times he provided to DF2ZC, but to be
watching for him if you are around. If he wakes up earlier, he MAY be on
earlier.... GL and VY 73, Lance

Also sometimes I could call CQ anytime on 144.138 (+/-). I have been CQn
sometimes as late/as early as 14z or 16z.

Hello Ray and all,
I have forwarded your email to Remi, not knowing whether he can be QRV earlier.
I have no permanent contact with him. All of a sudden I had received an email from him asking me the favor to forward his activity times to moon-net - which I then did.
However, since this is not a dxpedition as he lives in FK8 it should be just a question of time to work him.

Betreff: Re: [Moon-Net] FK8CP (RG37FR) QRV Schedule
Please, Remi operate earlier as we have no moon on these scheduled times...
Bernd, see if Remi will get on 4or 5 hours earlier, no one on east coast has moon in these times. just after his moon rise would be good...
Thanks Ray WA4NJP

I got news from Remi FK8CP about his next QRV times:
FK8CP will be CQing on 144.138 first:
1 April to 2nd April: 2040z to 0240z
2nd April to 3rd April: 19z to 0330z
3rd April to 4th April: 19z to 0410z
This is with some short breaks, a break for lunch and also
on rx, noise and other things. Also he could start earlier
GL on working a new DXCC!
