I have a problem with my 70cm cir Pol yagi. A feed line got tangled in the
antenna apparently when I moved the antennas from a high angle back to 0
degrees. A driver element was bent and nearly pulled completely out of the
insulator and matching unit. I pushed it back in through the insulator but
the analyzer shows no resonance at frequency. Is it possible to open up the
small matching unit box and repair such a problem or am I destined to buy a
new unit from M2?

I'm in the process of assembling a new system dedicated to sats and the
like. I have a decent steerable array, quality preamps, dedicated
computers, and radio with panadapter. I'm focusing on telemetry, decoding,
and other interesting downlinks. I am literate in Satpc32 and have it
running already. I'm soliciting information or ideas that I can incorporate
that might benefit the AMSAT community, recommendations for specific
satellite software, uploads, etc.
Thanks for your time.
Thanks for the info on others also having problems with the ISS packet digipeater. Thanks to K4KDR and KG4AKV. this confirms that I am not the only one experiencing problems. I also noticed that once the sat is no longer approaching that I cannot get into the digipeater and have trouble hearing it ..Evidently it seems to be the ISS antenna is no longer accessible from my location ??

The QIKCOM-1 module was to be powered by 28 volts after the host spacecraft
deployed its solar panels, charged its batteries and determined that power
was nominal. Since QIKCOM-1 also had a completely separate QIKCOM-11 VHF
beacon and separate antenna to come on over the USA too, and neither have
been heard, we assume the module has not been powered up. Both the host
and QKCOM-1 were delivered about two and a half years ago and spent most of
that time stored on ISS awaiting deployment.
We thank everyone who listened after the deployment on Friday, but since
both transmitters are on common APRS frequencies, monitored routinely in
USA and around the world we will surely see it anyway if it powers up.
Since it was deployed from ISS to avoid re-contact later, then it will be
in essentially the same orbit but going lower. And lower orbits go
faster. Deployed at 0.3 m/s or about 1kph, my guess is it will gain about
20 seconds a week.in front of ISS AOS as a wild guess.

I'm selling a Yaesu FT-847. I know it's a popular radio with satellite operators
so I thought I'd offer it here first.
Ship to USA only.

I know others have traversed much of Nevada in recent weeks, but I am
planning to also do something like that over the next 2+ days. With the
AMSAT Symposium wrapping up here in Reno, I plan on heading east along
I-80 toward Utah on Monday morning. I hope to be able to activate some
grids (DN00, DN10, DN11, DN20, DN21, DN30) before I stop for the night
somewhere around the Nevada/Utah state line. Tuesday will see a return
trip west across Nevada via US-93 and US-50, where I may be able to
make stops at DM28 and a quick excursion to DM39 inside Utah, before
hitting DM29 and DM19 on the westbound trip back to Reno. I might get
on the air Wednesday morning before returning to the Reno airport for
my flight home, probably from somewhere in DM09 one last time.
It looks like APRS digipeaters cover much of I-80 and US-50 across
Nevada, and I might show up as WD9EWK-9 on web sites like
http://aprs.fi/WD9EWK-9 as I drive around. I will also use my @WD9EWK
Twitter account to send out updates. If you don't use Twitter, you

I have already uploaded my logs to Logbook of the World from the past
few days' operating around Reno and Lake Tahoe. I'll do the same for
the QSOs logged in the next couple of days, but I might not get them
into LOTW right after each pass. Please be patient with the LOTW
