Hello David,
You may have missed my previous post, due to no subject in the title.
If you're looking for a shoestring-budget LNA for 2m, the U310 JFET
preamp has been a good performer for me.
http://www.ham-radio.com/n6ca/50MHz/50appnotes/U310.html
I've constructed one in a spare project box, and the gain (12dB) is
right on the predicted value. I have not verified the NF, but it is
claimed to be near 1.0dB. I built in in one evening, with some extra
evenings diagnosing a capacitor issue. Use a multi-turn piston trimmer
for the 1-10pF drain capacitor, as the output tuning is very sharp.
I've changed the layout a bit, but here's an early picture of the unit:
http://www.n0zgo.net/lna/
The air-core inductors are not difficult to wind on a 1/4" drill bit.
Not as fancy as a GaAsFET or pHEMT device, but it works just fine to
hear AO-85 and AO-7 with a non-ideal satellite antenna (folded
horizontal dipole) at 10 degrees above the horizon.

Mini Kits Australia make a very nice 2m switched preamp, 100W CW
non-sequenced, 500W when used sequenced.
Mark has a new version which uses the PGA103 mimic. I have two of the
previous version and they work very well. One I use for VHF
roving/portable use and the other is mast mounted. They do need to be
put in an enclosure of some sort and Mini Kits sells a nice enclosure
that fits nicely and is not expensive. I put mine in Hammond 1590WBBFL
diecast enclosures.
http://www.minikits.com.au/
http://www.minikits.com.au/electronic-kits/rf-amplifiers/rf-preamplifiers/EME2
20-2M
10 to 18 dB gain (adjustable) 0.8db NF
Mark is great to deal with, shipping is reasonable and quick, and the
exchange of US$ to AUS$ is attractive.
cheers, Graham ve3gtc

roughly the same price as the ARR, and considerably cheaper than some other
mast-mount alternatives. The IC-9100 powers them through the coax without
the need for any other supply.

For what antenna? I got the one that Arrow sells with their antenna.
Works fine. I also have a Comet CF-4160J. Works great ... but I've
never used it for satellite stuff (it connects a couple of middle-aged
IsoPoles to an FT90R at N5UWY).

Gerald,
I use the Comet CF-416C on several satellite setups. It works well as a
diplexer (two antennas to one radio) and as a Mode-J filter to keep a 2 m
transmitter from desensing a 70 cm receiver. See
http://www.amsat.org/?page_id=2136 .

Jerry,
I used to rely on Comet diplexers, but have been using the MFJ-916s
for a few years. They come in versions with SO-239 sockets all
over (MFJ-916B) or N sockets (MFJ-916N). They work just as
well as the Comet or other diplexers in my opinion, cost about
half of the equivalent Comet (or Diamond) units, and are not
made in Mississippi.
73!

I am running another Radio Merit Badge workshop for the National Scouting
Museum in Irving, TX, EM12, this Saturday, September 17 and activating
K2BSA/5. Weather permitting, this will be my first attempt to do a linear
transponder satellite pass contact during one of these badge workshops so I
am praying that the rain and radio cooperate. Look for us near the center
of the FO-29 passband on the 1801Z pass and take a minute to say hello to my
assembled Scouts and be patient as they say hello back.
73 and see you on the bird.

Call for Proposals
Proposal Window September 1 ? November 1, 2016
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a crew
member on board the ISS. ARISS anticipates that the contact would be held
between July 1, 2017 and December 31, 2017. Crew scheduling and ISS orbits
will
determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of
participants and integrate the contact into a well-developed education
plan.
The deadline to submit a proposal is November 1, 2016. Proposal
information and documents can be found at
www.arrl.org/hosting-an-ariss-contact.
****************************************************************************

ARISS is always glad to receive listener reports for the above contacts.
ARISS thanks everyone in advance for their assistance. Feel free to send
your reports to aj9n@xxxxx.xxx or aj9n@xxx.xxx.
Listen for the ISS on the downlink of 145.8? MHz.

I second the MFJ-916s... I have two in the mast mount box before the preamps
