Quick correction. The third pass should be
23:38z XW2B 19? West

I may also try the 23:10z XW2D pass depending on how the evening goes.

I'll be satellite-roving on Sunday 8/19 and Monday 8/20 to DM15/16/25/26,
likely also DM14. I'm planning to be active on FM, SSB, and APRS birds.?
I'll provide frequent updates on Twitter when I have mobile data/SMS
coverage, under the handle @????? with tags @????? and #AMSAT. When I
can,?I'll tweet some advance notice before each pass or back-to-back set of
passes.?LoTW uploads to follow later in the week. LoTW confirmations would
be greatly appreciated!
I'm still somewhat green on the linears, and manually tuning, so please be
patient. Please give your call at least two or three times to give me time
to tune you in.?
My operating plan follows, all times in UTC, with the number of leading
asterisks indicating the degree of confidence that I will make that pass;
three being the highest confidence. Looking to qualify for an AMSAT Rover
Award on this trip.?Hope to hear you on the birds!

If I may impose further on the group,  thanks to your assistance I am
able to get Gpredict to do what I need to do, and have configured the
software to match my radio and rotators.  I am looking for hardware
recommendations for a board that I can plug into my shack computer and
use as an interface between that and my new-to-me G5500.  I would
welcome any thoughts or suggestions you folks might have.

I have 1 bare circuit board for the FOD-Track, as well as an assembled unit,
if interested.  It does require a parallel printer port...

Subject: [amsat-bb] Measuring SMA relays at UHF

Hi all!

Playing with my toys, trying to create a CP 10x2 UHF antenna

Using an Anritsu S113b which does not have direct voltmeter readout.
These numbers were calculated by making a return loss measurement and
converting it to relative phase with their Line sweep tools software.

Converted data here:https://www.flickr.com/photos/n3ykf/

I have a Times T-100, using a similar procedure, very similar, almost
identical numbers were returned.

Setup: S113b has an N female. To make SMA, I added an  N male to male,
then a N female to SMA female.

Used a calibrated SMA OSL kit.

Test pieces: two Transco SMA 24V relays and an SMA jumper, consisting of two
elbows and some straight pieces.

Coax to be used in final device is RG-142B/U. (El Cheapo on the bay)

Did use a 5/16 wrench to snug up all the connections.

First order of business was to calibrate all the test gear. Noting how
long the adapters attached to the N connector were as well as noting
the length of the test cable.

Got some interesting results:

RYA NC: 232.2 degrees

RYA NO 231.8 """"""

RYB NC 231.3""""""""""

RYB NO 231.0 """"""""""

SMA jumper to connect Common->NC to NC->common 281.3 degrees.

Does this look correct? How does such a small package contain such a
lengthy RF path?

I went through this whole process (took about 5 times longer) prior to
my trip to 5J0 and realized that mistakes had been made. Skipped the
CP attempt, Took the pair of crossed linear 10 elements, diddled by a
Tohtsu spdt 12v instead
Worked like a charm from AOS to 5-7 degrees above the horizon so that
I could switch polarities. What a blast. Used my homebrew rotator.

Please ignore my 2yo little monsters. They can and do make s9+ noise.

Trying to get the coax for a cp antenna correct this time. Waste no more
coax..

Currently in the field. I'm wondering if there's something inside the
relays making them look longer. Coax seems to be realistic lengthwise.
SMA jumper is maybe 6cm long. Measures slightly longer than 3/4
Lambda, though.... Will make some measurements to a test article,
disassembly and photos.  Stand by, pussycat!!
