View Full Version : The birds
Anyone else working the birds?
VO-52, FO-29, AO-51 and now ISS are all active.
I've worked 26 states in the last month on the birds.
Who else is active?
No sat guys at all.
I used to work the Russian HF birds...
Just got this the other day from ARRL about a neew repeater on the ISS:
==>AMATEUR RADIO ON THE INTERNATIONAL SPACE STATION IN REPEATER MODE
NA1SS aboard the International Space Station is now operational as a Mode
U/V (Mode B) FM voice repeater. Amateur Radio on the International Space
Station (ARISS) Ham Radio Project Engineer Kenneth Ransom, N5VHO, said July
20 that the system appears to be working well following a week of silence
during an initial attempt to activate the repeater.
"John Phillips, KE5DRY, gave it a second try after a scheduled contact with
Goddard Space Flight Center," Ransom told ARRL. "On the next pass, I was
able to work four stations." Just how long the repeater mode will be active
remains to be seen, and it could be switched off after the next ARISS school
group QSO or because of the space shuttle's arrival (NASA plan to launch
Discovery on Tuesday, July 26).
Phillips and crewmate Sergei Krikalev, U5MIR, can step in and talk to Earth
stations if they wish; otherwise, the system acts as a crossband repeater
when the ISS is within range.
"Enjoy it while it lasts," Ransom remarked, "because we don't know when
they're going to shut it off."
The uplink frequency is 437.800 MHz; the downlink is 145.800 MHz. The RS0ISS
packet system is off the air while the voice repeater is in operation. Since
the ISS equipment is channelized, it cannot correct for Doppler shift, which
can be significant at 70 cm.

I don't have UHF capabilities down that low right now but I have the downlink on scan on my IC 2710...in the car.
The ISS was not in voice mode today. I havent checked this evening's passes yet.
