Yes, super strong signal from WA4SCA although even that wasn't holding
the repeater open all of the time!

Hi Alan:
While new to the on-line logging stuff, I do both--I see them providing
two seperate functions. LoTW is simply a method to electronically match
logged contacts for ARRL award programs. eQSL, is more of a generic
replacement for traditional hard-copy QSL mailing.
At least this is my take on them.

Yeah, that was tough. I had a short QSO with WA4SCA near TCA. I have ~2500w
EIRP on L, minus some trees, and could only bring it up above 45 degrees,
and lost it when the rotors went 360. I think some of it must be shielding
of the ISS antenna, because there was a sharp transition from doesn't work
to works.
Thanks Alan, and thanks to the ARISS team!

Rick,
Witty conversationalist that I am, it was good to work another station. :)
Drew came in near his TCA, dropped out for a minute, and then came back just
before my LOS. In both cases, the limiting factor seemed to be breaking the
squelch. As the ISS moved away, I had a good shot at the earth facing
antenna, and had to slowly ramp up the TX power as the range increased. I
could actually get in almost to my LOS due to a clean local horizon here,
but the power to the brick amp was approaching the "Danger Will Robinson!"
level.
I am wondering if they could experiment with opening the squelch up a bit?
I understand the cooling issues, but expect there may be less spurious
signals on mode L than the normal frequencies.
FWIW, pass was AOS at 295 degrees azimuth, 18 degrees elevation, and LOS at
azimuth 140 degrees, 12 degrees elevation. I suspect in both cases power
limited.

PS Thanks to all for the receptions reports from listeners. They have been
highly encouraging and helpful!

Yes, its size is very wasteful. But we were surprised that we could hack-saw
off one edge of the board and make it fit inside a 4" cubesat and only have to
move the first coil a little bit. Though we have since found a smaller
receiver, though not crystal controlled...
Even with the hamtronics and modern APRS pic processors, we could easily fit a
full 5 Watt APRS digipeater into HALF of a cubesat, leaving the other half for
other experiments.

Won't work for packets, or at least would require a long TXD making packet
communicatiosn inefficient.
As to rarity, only one filter in the whole world is needed and that is on the
uplink receiver. This lets eveyrone on the ground use conventional rigs
without mods, and with minimal doppler uplink tracking.
Too many simple satellites are being built without considering the need for a
wider bandwidth receiver on the uplink. The difficulties of such an approach
for users is very obvious on the ISS cross band repeater, which is using a
stock amateur transceiver with a 12 KHz wide receiver on the uplink, which
makes even 5 KHz step tuning on the uplink be out-of-bandwidth splatter half
the time.
This is not a complaint at all. The ISS team is to be congratulated for
making the most of what they were able to get up there. It just takes more
skill by users on the ground...
It is good to see this new UK project planning on a wider uplink RX filter.

I'm using the beta HRD (rev 4.1 build 2055) that offers the new Sat module.
This was very handy in the ISS SSTV passes of late but I'm having some
difficulties with FM and SSB birds with Doppler. I run a pair of Yaesu FT-
857Ds and It corrects very quickly, several times per second, interrupting
audio with each correction. This makes for near impossible copy on the
downlink, often causing me to disable correction and follow manually. SATPC32
corrects less frequently and is easier to copy with, but I'd really like to
get HRD working right with the integrated logging and all.
I've been unable to locate any settings to adjust the frequency of correction
and I seem to recall the "old" Sat module could do this. Has anyone else
encountered and resolved this challenge? I have posted on the HRD forum with
no responses.
BTW, thanks to all for posting the manual process for following Doppler. Being
new to SSB sats, this is very handy to have. I was wondering why I would hear
a quick whistle noise as folks locked in!
Regards,
Mike WB1AAT

Mike,
For reasons unknown, those rigs mute the audio when changing frequency via
CAT. I use another rig, but it has been reported that only the speaker and
headphone outputs are muted, and that if you take the audio from the
data/aux outputs there is no problem. Not specific and second hand, but you
might want to look into that, as that is the real problem.

Sadly a restriction with these Yaesu radios :-(
If you manage to pick up a used FT-847 then do so!

If you are chasing VUCC - LoTW currently is not configured for VUCC.
I still upload those logs however, in hope that if they ever do
configure it for VUCC, my data is there.
