There seems to have been a rash of postings lately about how to get on
the the "birds" for "cheep" ( yes the pun is implied!).
IMHO cheap is not always equated with good. No one wants the "cheapest"
Doctor around or the "cheapest" lawyer or the "cheapest" anything.

INCOMING CME: Active sunspot 1401 erupted yesterday, Jan. 19th around 16:30 UT,
producing an M3-class solar flare and a full-halo coronal mass ejection (CME).
The Solar and Heliospheric Observatory recorded the cloud expanding almost
directly toward Earth:

Greetings from the frigid north country,
I have used my single IC-706MKIIG with the linear sats. Back in the day I
had a table full of receivers, transmitters, transverters, preamps etc to
operate full duplex on AO-10 and the other sats. Since I had not been on
the sats since then it almost seemed
Does anyone know if Hamstronics has made a UHF receive converter? The
currently make one for 2m, but I would like one to use for FO29, if
possible.

John,
They did at one time. You can find the manuals here:

High Sierra Microwave makes receive converters, and they are very high
performance IMO.

A solar flare will disrupt all HF and some satellites,While the flare is
hitting the earth ,it can cause the VHF bands to open up .After the flare
passes then the HF bands will be very active for F2 and maybe even some on 6
meters too

The flare prompted a call from a friend who was operating his remote HF/6m
station in Puerto Rico. He thought something had happened to the radio. Told
him he either had his G5RV knocked off the tower or someone tinkered with radio
controls. Then i told him maybe a solar flare reached earth. Loo
I do think we need to be careful that we don't send the message that you
must have a complex (and expensive) station to work the FM sats. I
wouldn't want someone interested in the sats to give up because they
thought they needed circularly polarized yagis, elevations rotors, mast
mounted preamps,
There was a presentation on building a distributed satellite ground station
network at the Chaos Communication Congress held December 27-30 and the video
is now available.
The AMSAT-UK FUNcube Dongle VHF/UHF Software Defined Radio gets a brief mention
at 39:26 into the video.

One thing I learned the hard way about Hamtronics converters is that
they can't take any transitory transmit RF. Just powering up my old
TS-440S with a UHF Hamtronics converter attached would blow the MMIC.

Hi all.
Am in the process of building a quadrifiliar helix antenna using this page:

How much cable should I use between the device under test and the antenna

Whenever I do a satellite demo with my 910H, Gulf Alpha CP antennas, az/el
rotors, and computer control, I always take along an HT and a tape measure beam
& show my audience that the FM birds *can* be worked with a much simpler setup.
HOWEVER, I always stress the same rule of thumb that appl

like most everything else, "you get what you pay for". I suggest those who
want to get the cheep stuff. Donate the money you would have spent to AMSAT.
This is rocket science, and that ain't "cheep".

Hi John,
Hamtronics previously offered a UHF receive converter. It was available as a
kit and was a mix
of through-hole components and surface mount. This was the first surface mount
kit that I built.
There were two options for the crystals, so that it would convert either 435.0
MHz or 43
