Happy New Year, everyone...
Last night's Straight Key Night was fun! I was pretty impressed with the
amount of stations on the linear satellites participating in the event.
Worked a few, missed a few, but still enjoyable all night.

I'm wondering if anyone can recommend a USB to serial convereter that works well with SAT32PC and an ICOM 706 or a FT 736.
Conversely if anyone has had bad experiences that would be usefull to hear about as well. I've heard that some USB to serial converters work better than others.

Happy New Year!!
The ARISS team hopes you are all enjoying the diverse amateur radio
opportunities that have occurred on the ISS over the past several weeks. We
want to thank Mike Fincke, KE5AIT, for his outstanding support to the ISS
Ham Radio community. His efforts have been phenomenal!
This e-mail provides an update of the ARISS special event opportunities for
the next two weeks. As previously mentioned, the ARISS team is currently
celebrating 25 years of amateur radio operations from space.
This past week, the ISS Ham radio system was configured in the L/V crossband
repeater mode. This configuration will continue through to Saturday when a
school contact is scheduled around 10:35 UTC. After the school contact on
Saturday January 3, it is our plans to have Mike Fincke reconfigure the
radio to support V/U crossband repeater operations. As a reminder, that
configuration has a 145.99 MHz uplink frequency including PL tone of 67.0
and a 437.80 MHz downlink frequency. All repeater operations are being
performed in low power (5 W) mode. It is our intent to keep the repeater
active in this configuration for 2 weeks (through January 17).
We are also considering follow-on experimental operations of the 9600 baud
packet radio system and the L/V crossband repeater. Stay tuned for future
As a reminder, a special certificate is being developed for those who
communicate with the ISS. This certificate will be awarded to those that
have had 2 way communications with the ISS on Voice, Packet (APRS), or
through the voice repeater. And those that have heard the ISS from space in
any of the ARISS operations modes (Voice, SSTV, School Contact, Voice
Repeater, Digital). Valid dates to qualify for certificate: November 30 to
To receive the certificate:
A) Please note on your QSL the ARISS mode of operation (e.g. SSTV, voice,
school, etc) and whether the contact with you was 1 way (receive only) or 2
B) Send your SASE to the normal ARISS QSL volunteer distributor in your area
of the world.
C) On the outside of the QSL envelope, please include the words "25th
D) Make sure your envelope is big enough to accept an 8.5 by 11 inch
certificate and includes the proper postage.
E) Go to www.ariss.org if you do not know where to send your QSL and please
use one of the standard international QSL distributors that are noted on the
Important note: We will be sending your certificate to the volunteer
distributors in bulk AFTER the event is over. (This saves workload and
money). So do not expect to see it until 1-2 months after the event closes
on January 15.
We would like to remind everyone that ISS flight requirements related to EVA
and vehicle activity may require the radio to be off for some portion of
this schedule. And school contacts and general QSO opportunities by the crew
will also preempt this schedule for short periods of time. (But remember
that if you hear these, you still qualify for a commemorative certificate).
Continue to enjoy the ARISS ops on ISS in 2009!

on the ~16:32 UTC pass. Seems like I was running enough power on the uplink
to ionize every fluorescent light bulb on Station!
Happy New Year.
> I suggest you consider AFC.
> Not enough demand for that wide a filter.
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.

A few days ago I posted the problem I was having with my new 817 and
satpc32. After emailing with the very kind Erich (creator of the software),
we were able to find the source of the problem in the CAT delay setting
(standard value was 110, but mine needed to be higher for some reason).
Below is my email to him with observations for any who might be experiencing
The strangest thing..... I came home and changed the CAT delay from 110 to
200. It worked! Both the mode and frequencies were changed for vfoa and vfob
and everything was good. Out of curiosity (and thinking it might help with
any troubleshooting you may need to do), I changed the CAT delay to 150. My
observations were that both the mode and freq. would change for vfoa and
vfob, but the interval settings did not work. What I mean by this is the
radio would switch between both vfo's on a very rapid basis, basically
whenever there was the slightest Doppler change, it would retune. Obviously,
this would make the receive audio extremely choppy.
To sum it up:
110-change downlink freq. and mode, change uplink mode only, rapid toggling
150- change downlink freq. and mode, change uplink freq. and mode, rapid
Repeater active for 07.18utc UK / Europe Pass.
Max 20dg elevation here so too low for Tx antenna.
Excellent signal via repeater from IW4DVZ calling CQ.
No other stations heard.
