QRP Contact

Hello All, I am really happy with whis event. I made my first contact through the ISS crossband repeater. My equipment was only a HT Yaesu VX-2, 1 Watt power and no special antena. I Made contact with CE2SOC and CE3TMM, alse I received SWL reports from CE6ABC, CE6UFF, CE6UFY and CE8VJG and someone from Argentina (QSL cards are on the way). Field Day was succefull in Chile, many stations on the air. I hope Crossband repeater will be active in the future for more time, we'll still working ISS.

ISS Repeater results - thank you Kenneth !

To Kenneth, N5VHO,

Dear Kenneth,
Having the ISS repeater on for FieldDay was a big success !

On the evening of June 22 I was awaiting the repeater to be
switched on. The first pass APRS was still active. Second pass
there were no downlink signals at all, so I knew someone up there
was working on the D700 - tension further growing. And YES !
The third pass (~21:30 UTC) the repeater was on, working great,
and both myself and Ib, OZ1MY made a QSO with Jeff Williams.

In the days after, many stations were able to make contacts, and
to my surprise there was no chaos this time on the passes over
Europe. Very polite traffic, and all stations waiting for the others
to finish their QSO's. Lot of fun !

Portable access was doable too: with my Kenwood THD7 (2W) and
only a 7 elements handheld beam I made on June 24 a QSO.
Compared to AO51 the D700 in ISS is much more sensitive to
doppler correction, but with 3 memory channels it worked fine.

The audio over-modulation is still for many stations an issue to
handle, but it seems most of us can listen full-duplux, as after one
day this this was under control. Is there a setting in the D700 that
we could change for this ? Or is the crew mic level setting coupled
the audio level of the uplink receiver (in which case we should not
change anything as the crew's audio is excellent via the repeater) ?

Anyway: I thanked Jeff for switching on the repeater, but I also
wanted to thank you Kenneth, for organizing all of this.

Many thanks on behalf of all the stations that had a great weekend!

I have listen to the ISS REPEATER DOWNLINK QRG!

I have listen to the Downlink frequency from the repeater and on 22. June 2006 when the repeater was active since a long time i haven listen. I am waiting for the packet signal and the voice is coming, from Jeff and some european stations, and i am really happy that i hear amateur radio stations via the iss repeater with their voices. I have at the fieldday only listen on sunday for 1-2 passes over my QTH and the signal during the passes was very good. And i hope the next time it comes again a ariss school contact over Europe and we can listen to the voice again from the crew 13 again. And when the STS121 is docking and Mr. Reiter is staying on ISS i hope than he make some contacts with the voice for the whole world for all amateur radios.

I was able to make two QSOs

I was able to make two QSOs via the repeater the first day it was on over the USA using 0.5 watts. Did not have any luck using it on Field Day, but I was able to work the AO-51 QRP repeater.

Didn't bother to try the ISS during Field Day


Between the pass times and my thoughts about how crowded the ISS repeater would be, I didn't plan on trying it out. As it turned out, I missed the passes Saturday evening, and didn't stay up for the early Sunday morning passes. I was able to make contacts on AO-51 (the "normal" repeater and the QRP repeater) and SO-50 with my IC-W32A HT and Arrow Antennas handheld Yagi. AO-51 was very busy, but SO-50 wasn't as crowded at 1920 UTC Sunday (after many stations probably shut down).

I did make 8 contacts through the ISS cross-band repeater on Friday evening (early Saturday morning, UTC) before the Field Day start time. Two passes, 4 QSOs on each pass, using 5W from an IC-2720H and the Arrow handheld Yagi.

I managed a couple of contacts using just a D7 handheld and arrow antenna for my local club (NU5M) to be able to claim the 100 point satellite bonus.

ISS repeater!

It was great with the repeater on!
Sadly it was a bit short period!
I look forward to see it on again!

Video of two sessions of passes are available


Two video clips are available on the above site. If you use non-Internet Explorer browsers, scroll down on the page to see the windows featuring the video clips.

These contacts were preparations prior to FD. The actual FD contact from Saturday is still in the video camcorder. I'll upload it in a few days. Just came home from presenting on digital emergency communications at our local civil defense organization.

The ISS on the "advertised" early Sunday morning pass turned out to be on packet, rather than crossband voice.
