Sorry, no way will I support a SETI-type mission using amateur frequencies
for their downlink. Not with my money, nor with my station resources. This

Subject: [amsat-bb] SatPC32 CAT control and HDSDR via VSPE
Message-ID: <002001d15bec$0cbc94f0$2635bed0$@xxx>
Content-Type: text/plain; charset=us-ascii
Hello all,
Not having a good satellite capable radio (Yet) but wanting to dabble deeper
in to our world of satellite communications, I have been experimenting with
CAT control of the SDR program HDSDR via the CAT interface from SatPC32
through the Virtual Serial Port Emulator (VSPE). VSPE has an option to
create a serial port "Pair" of ports. In this case, you have to assign one
port of the pair to SatPC32 and in HDSDR's CAT to HDSDR options, you match
the baud rate in HDSDR and SatPC32 but assign the other half of the pair.
Cool thing is it allows HDSDR tuning to affect the frequency listed in it's
downlink window while continue to track Doppler shift adjustments provided
from SatPC32. This is pretty cool.
Well I have an interesting question which may relate as much to the way
SatPC32's CAT control window works as much as it relates to this Virtual
serial port thing. The above mentioned ability to tune SatPC323 from HDSDR
works wonderfully on Linear transponder (LSB/USB) modes but not the same on
FM modes like Lilacsat-2, SO-50 and AO-85. In these cases, shifting the
frequency on HDSDR does NOT change the SatPC32 display and in a few seconds,
HDSDR snaps back to the CAT controlled frequency. Now the difference of
course in SatPC32 CAT adjustment window is the inability to shift and store
the changes in frequency, or even just shift them in FM mode like one can
do with Linear sat frequencies.
Am I missing something here or is this just a built in feature of SatPC323
that I will need to work around by providing more appropriate Doppler.SQF
setups that work for me as opposed to somebody else?
Anybody who has played with this please drop me a note or share your
experiences via the list so more people can lear.
Thanks,
Tom Schuessler

Hi Tom,
with FM sats the SatPC32 control "V" ( for "VFO") goes to "V-". Click it
to "V+", then all tuning functions work like they do with SSB sats. When
you tune HDSDR SatPC32 will follow and vice versa.
FM sats work in fix channels, therefore the program disables the VFO
feature by default.

Dear Pavel,
Does Direwolf do BPSK? As far as I know it only does AFSK and FSK, but
I'm not aware of the new features of current versions.

this morning...

Hi!
It was nice to hear XE2AT on SO-50 during the 1440 UTC pass this morning.
It has been almost 5 years since I logged a satellite QSO with Alvaro, and
he used to be among the most prolific of Mexican satellite operators who
worked from different grids in that country. In fact, Alvaro (as XE2YVW,
his original call sign) was my first satellite contact back in 2000, via
SO-35. I'm glad his encounter with the police last night didn't leave him
without gear for this morning. I heard Alvaro tell Clayton W5PFG that was
"working on more". I hope he is, as it will be nice to hear more grids on
the air from Mexico once again. XE2AT, and initially as XE2YVW, has put
many Mexican grids on the satellites over many years.
The 1440 UTC SO-50 pass came up from the southwest, and went directly over
Arizona. I was happy to work XE2AT early in the pass, once the satellite
cleared a house and some trees to my southwest. After I worked him, I
heard XE2AT acknowledge 7 other stations with their full call signs -
KC7MG, XE1AO, AA5PK, W5PFG, NP4JV, W5CBF, and XE2BHL. I heard Alvaro try to
answer one station twice with partial call signs after working XE2BHL, a
different partial call each time. Unfortunately, I did not hear XE2AT after
the midpoint of the pass here, which meant he wasn't able to work stations
for the last 4 to 5 minutes he would have had on that pass.
I also heard Sean KX9X/5 working from the Vicksburg Military Park in
Mississippi. Thanks for picking me up, Sean! In the last few minutes I had
on that pass, I heard Sean get several stations for his log. It will be
nice to see another NPOTA site show up in LOTW. :-)
XE2AT has used LOTW in the past, although I have never received an LOTW QSL
from him for any of our satellite QSOs. Omar XE1AO said that Alvaro can
confirm QSOs via LOTW, so it will be nice if these grids show up in there.
I know XE2AT has been good answering my QSL requests sent to his PO box
over the years, and I'll mail Alvaro a QSL card with SASE. If anyone else
wants to send XE2AT a QSL card with an SASE, I have lots of Mexican postage
stamps. Please e-mail me directly, or send me a direct message in Twitter,
and I can get some stamps out to you.
73!

Hi!
After working from the DL52/DL53 line on the south end of the
Baja California peninsula this morning, Alvaro XE2AT plans to
work the 0100 UTC SO-50 pass tonight (5pm Pacific time) from
the DL42/DL43 grid boundary. This is northwest of Cabo San
Lucas, near the southern tip of the peninsula. SO-50 will be
over the eastern Pacific Ocean during this pass, meaning the
footprint won't make it all the way to the Mississippi River.
DL43 has been on the satellites in past years, thanks to
Bernardo XE2HWB (worked satellites in the past, also active
in VHF/UHF/microwave contests from up and down the Baja
California peninsula), but not recently. DL42 is almost entirely
wet, except for the small bit of land in the northeast corner
of the grid - similar to grid CM86 at Santa Cruz in northern
California.
XE2AT mentioned earlier this morning that he plans to use LOTW
to confirm these contacts, along with the contacts he made
earlier this morning. He's also good at answering QSL requests
mailed to his PO box in Aguascalientes, although the Mexican
postal system is not the most reliable.
Good luck, and 73!

Hi folks,
I'm trying to get on the air with the linear transponder satellites, and
it looks like I need 70cm SSB capability to really get on the air. My
Icom IC-796MkII can do SSB on 2m, but not 70cm, so I'm trying to find an
affordable way to get 70cm SSB transmit.
Does anybody have experience with these $100 transverter boards from
Ukraine? It looks like they're tuned for the weak-signal/SSB end of the
band and might require a bit of work to get up to 435MHz for satellites.
Is 3-4W enough to be heard?

Eric,
I don't have any experience with that transverter board,
or with transverters generally. If you can get the 70cm
board to operate at 435-438 MHz, it could be useful for
satellite work even at 3 to 4 watts. I regularly work
the SSB transponders with a 5W FT-817ND as part of my
portable station. If you could get that transverter up
toward 4W, it could work as an alternative to a radio
like an FT-817ND.
For my portable work, I use short coax runs - 10 feet
between antenna (Elk 2m/70cm log periodic) and a 2m/70cm
diplexer, and 3-foot runs from the band ports on the
diplexer to my transmitter and receiver. Longer coax
runs may not be the best for that 3-4W output, and
could also require the use of a preamplifier on receive.
73!

Does anyone know if there will be a S band DL on any future satellites. Are
there any current sats that have S band DL for telemetry?

A question is how is the LO generated. If 432 gives 27, this thing has a 405
MHz LO. Satellite subband is mostly ~435-436. That would require an IF radio
to tune ~30-31 MHz. Most don't. If the LO is crystal controlled, changing
crystals is ridiculously expensive; like $40-60. Not a great value. The LO
could be synthesized and might be modifyable. Maybe. I would write to the
seller and ask if the LO can be changed.
