As planned, AO73 is now back in autonomous mode until Friday evening when the usual "weekend of transponder" mode will be restarted.
In other news, please be aware that AO73 will start to experience much shorter eclipse periods during this month and will be in full sun for some weeks starting around 6th February until 13th March. The operating modes for this period will be announced nearer the time!
I’ve become aware that my Arrow may be failing. I’m less and less able to hear the birds towards LOS and sometimes it’s taking the 1st 1/4 of an FM pass to hear anything typically more than 30 degrees elevation.
I know there are many of you working at much lower elevations so I’m beginning to think I have a problem. It’s a salty environment here in C6 and there a little corrosion here and there. Sadly, I have no antenna analyser with me for UHF or VHF. I’ve already stripped it down once and cleaned everything so any advice on the following gratefully received:
What elevations is it reasonable to hear each FM sat using a THD-72 (listening VFO A). What other places might I look for reduced performance?
Thx and 73

Just wanted to mention a couple of items.
Terry Osborne, ZL2BAC, noted the desire to use elements made from measuring
tape to reduce weight. I have used a novel approach to using tape that
allows the antenna to be quickly broken down for transport as the 2m
antennas can be a little bulky to say the least!
If interested, look for the title, "Tape Yagi-Uda Antennas for 2 meter and
70 cm Satellite Operation," at the bottom of this page of my site:
http://ki4sbl.dodropin.org/Antennas/Antennas.html . The NEC design files
and a report of antenna measurement results from the SVHFS Conference in
Charlotte last year are are available, as well. Please let me know of
results (and especially any improvements) should you decide to build these
On a somewhat related topic, there are only three (3) CNCTRK AZ/EL
rotator/positioner kits remaining in my eBay listing. The tape Yagi-Udas
work well with the positioner.
There was a possible report that the HOST spacecraft for QIKCOM-1 may have
been heard from.
If so, there is a chance that QIKCOM-1 may get powered up. I checked the
PCSAT.FINDU.COM and SATWATCH web pages and see no hits...
But since those websites have never seen a QIKCOM-1 packet either, then we
don't know for certain if they will capture it if there ever is one...
Possible QIKCOM-1 callsigns are QIKCOM-1, QIKCOM-11 and QIKCOM-3..
Very small chance, but something to notice if you see it.
On 145.825 (and possibly 144.39 over the USA)...
Don't waste your time, but just be aware it is still up there, and if the
host ever powers up, then we come up too.
I offered to take over the Monthly VUCC Awards/Endorsements list that John, K8YSE, has been posting on this list.
If anyone has comments or suggestions for changes to the list, please let me know. Otherwise I’ll be following a similar format that John has been using.
Happy New Year.
It's a new year, and I still have a couple of free days this week. I
am going to make another quick run to the DM34/DM44 grid boundary in
northern Arizona on Wednesday, 3 January 2018. If all goes well, I
may be able to sneak in on the western FO-29 pass starting just before
1700 UTC. Otherwise, I will start with the SO-50 pass coming by just
after 1700 UTC. Along with these two satellites, along with some
others - AO-91, FalconSat-3, even AO-7 if it stays in mode B for a
pass around 2026 UTC.
I will use APRS for the drive up to the DM34/DM44 line and back on
Wednesday, squawking as WD9EWK-9. This should appear on sites like
http://aprs.fi/WD9EWK-9 among others. Updates will be posted on my
@WD9EWK Twitter account while I am up there. QSOs will be uploaded
to Logbook of the World after the quick road trip. If a QSL card is
needed to confirm a contact, please send me an e-mail with the QSO
details. If you are in the log, I will send you a QSL card. No need
to first send me a card or SASE.

If you are using WISP and can not open the help file, then I decompiled and
compiled an HTML version. Unfortunately it does not link directly from the
help menus in the program, but you can read it and search for topics. If
anyone has a better solution then let me know.
It is here for anyone that wants it:

Here are the endorsements and new VUCC Satellite
Awards issued by the ARRL for the period December 1, 2017

This list was developed by comparing the ARRL .pdf
listings for December 1, 2017 and January 1, 2018. It's a visual
comparison so omissions are possible. Apologies if your
call was not mentioned. Thanks to all those who are
roving to grids that are rarely on the birds. They are
doing most of the work!
This report was the 12th in a series covering 2017. It is
time for someone else to take it over if there is any interest.
Simply download the .pdf file from the ARRL website on the first of
every month and do a comparison with the last month. Keep in mind
that these reports are not archived so if you don't download it
on the 1st, that report is gone on the 2nd of the month. The January
1, 2018 report can be downloaded at papays.com/vucc01012018.pdf (It will
stay there until mid February.)
Happy New Year.
