The V/U repeater is strong but HRD is tracking it late although I have forced
an update to celestrak keps. I suggest this means an unexpected orbital boost.

~1900 GMT). See http://www.issfanclub.com/node/8152 or

Best to update your ISS keps daily as it is constantly changing.

Good Evening,
I am looking at finally getting my controller on the air. I have it hooked
up to a G-5400G rotor. Under SatPC32 it appears to only give you com port
access (1-4). Under Nova, it only gives you com 1-8. Linux does not seem to
mind any thing, but I can not get rotctl to work.
Is there a program that works with this unit that does not limit com ports??
Any one using Ham Radio Deluxe? Can it work with HRD?
Is there any one that has this working under Linux?
Any one using a TS-790 in either OS?
I know there are more questions, but I have not gotten this to work.

Hi Will,
under SatPC32 you have COM port access to an unlimited number of COM ports.
COM 1...20 can be set directly in the setup window of the driver program,
port numbers above by changing the data file with an editor (i.e. Notepad).
The port numbers 1..4 in the menu "Rotor Setup" relate to the parallel
ports.
I don't know the Sat688 controller. It seems to be easycomm1 compatible
(see http://www.arrl.org/FandES/tbp/ariss-kits/ ). 2 of the driver programs
that come with SatPC32 support that protocol.

Hi Gordon,
many thanks for the qso. Your handheld effort was significantly better than
mine and I appreciate your qso discussion and signal report. I'll be delighted
to exchange cards if you would like to - and of course you can now claim the
25th anniversary ARISS certificate as CONTACT (REPEATER) with the ISS! Not bad
at all for 5 watts handheld!
The reason I asked you about the audio was this. I was using a doppler
corrected system using Ham Radio Deluxe which depends on accurate and up to
date kepler elements. This was producing really bad audio on the receive side
and after talking to you I realised that the problem was that the ISS had
reboosted its orbit - but this had not been refelected in the keplers used,
even though I had forced a reconnection to the celestrak server. (Incidentally
the AMSAT on line predictor had earlier given the same times for AOS and LOS)
So the ISS was "late" in terms of the predicted and my doppler system was not
tuning correctly to the downlink, hence my receive audio problem. After
talking to you I retuned manually up in receive frequency but alas! too late
to make another qso.
My friend Colin G1IVG had the same problem and when I reported it on the amsat
bulletin board Sebastian W4AS reported the same thing.
Because you were manually correcting for doppler, you beat the machine! you
were tuning by ear in 5khz steps on the Kenwood and it worked properly.
So many thanks for the qso, it allowed us to figure out what was going wrong
and to alert stateside via the amsat bulletin board. and the iss fan club
site.
I hope you don't mind but I'm copying this whole correspondence to the amsat-
bb to celebrate the contact and what we learnt from it.

Regarding ISS and the accuracy of the predictions.
The same was noted yesterday at around 14:00 UTC. AOS was about 2.5 min's
late and was able to work via the cross band repeater until it was 5 degrees
below the horizon!
My Keplerian data and PC clock is up to date, I also suspect that there was
an orbit change and the "new" Keplerian data has not been made available
yet?

Yesterday
I demo ham radio to about 50 middle school kids in Lafayette ,La. The demo
went very well thanks to those who help out. What did not go so well is that
our Echolink did not allow multi connects so not all of you could get in.
Echolink is a good way to demo ham radio in a class room despite the fact is
not a pure radio circuit.
Thanks again

First of all, Smart Beaconing is not really a bandspace conservation
mechanism, but is more like an exact-track-assurence algorithm. It tries to
make sure that your position reports reflect all turns throughout your travels
and then a lower rate on straight stretches. Yes, it is better than
transmitting every 30 seconds forever (to get a good track) but when one is
maneuvering around in the city and mall parking lot, it can be a network hog
due to all the turns. It makes no sense via an occasional satellite to be
using an algorithm designed for optimum track-history.
APRS was never designed or intended to be a TRACKING system, and certainly
does not have the bandwidth to give everyone a precise track. On the
contrary, APRS is a communication network between amateur radio operators, not
a vehicle tracking system. THe purpose of your position beacon on APRS is to
let fellow net participants know approximately where you are for the purpose
of COMMUNICATIONS. One report every several minutes is fine.
Via satellite, only one report per pass is expected, maybe two for
reliability, to assure you are indicated as active.
Hence, a fixed rate just updating your approximate location periodically is
all that is required. For terrestrial APRS netowrk the best algorithm then is
PROPORTIONAL PATHING. It maintains a low, but fixed rate, direct, and sends
packets via 1 hop only half the time, via 2 hops only 25% of the time thus
maintaining good network accountabilty to other users close in, while reducing
netowrk load at a distance. Ths algorithm is built into the new D710 APRS
radio.
For reporting in from the wilderness via satllite (say PCSAT-1), the only path
that works when PCSAT-1 is in default mode is VIA W3ADO.
The path via WIDE1-1 will not work via PCSAT-1, W3ADO-1 or the ISS. Well, it
will work via ISS, but the www.ariss.net web page will not capture it, because
the ISS does not do callsing substitution when that path is used. Therefore
the APRS-IS system will not recognize it has having been digipeated via the
ISS, though it will show up on other FINDU pages.
For attended uplink on 145.825 from wilderness areas, for mobiles, a rate of
once every 2 minutes is receommended. For mobiles in-motion, actively
operating a pass, a rate of 1 minute is acceptible.
Good luck

Hi!
Has anyone used a Yaesu FT-8800 2m/70cm FM mobile radio to work the FM
satellites? It appears to have everything an operator would want for
those birds - separate VFO knobs, the ability to function as a cross-
band repeater, various power levels (for 2m, 5/10/20/50W), and the
control head can be permanently connected to the rest of the radio.
The power requirements, according to the manual (maximum 8.5A on 2m),
would work well with the "jumpstart" battery packs (mine are 12V/20Ah
gel-cell packs) I use to power my gear in the field. From a quick
reading of the instruction manual PDF, it seems like it could be a good
radio for this.
I'm looking at an alternative to my IC-2720H mobile radio I typically
use for my portable operating, which is in current production and has
a control head that was designed to mount on the radio. The TM-D710's
control head does not hook up to the radio, and radios like the TM-V71
and DR-635 only have one VFO knob. I'd like to be able to directly
control each VFO, without having to change bands in order to do this.
The IC-2820H could meet my requirements, but its retail price is too
much for me. The FT-8900 could also work for this, but I really don't
need another radio for 6m and 10m FM. I would pair this radio with an
Elk Antennas 2m/70cm log periodic and a homebrew PVC handle for the
antenna, so I don't have to deal with a duplexer/diplexer for a
satellite station I can pack into a small bag for travel.
Thanks in advance, and 73!
