Cross Band 437.80 up / 145.800 down Repeater Use? When NA1SS is not operational?
437.80 up / 145.800 down Repeater Use? When NA1SS is not operational?
I have not seen any activity posted since 2009 for using the 70 cm(437.80Mhz) uplink into the ISS repeater/ to the 145.800 Mhz voice down link. Is this cross band repeater mode still available or operational here in July 11, 2010? I would think it would be fun to make repeater contacts when Colonel Douglas Whellock is busy with work. I really appreciate hearing him from NA1SS making Amatuer radio contacts when flying over my and your QTHs.
So has anybody tried to call on the cross band repeater mode lately? I am still leargning to listen to ISS as they travel overhead.

I encourage those with good antennas and dual band radios to get active on making cross band 437.80 / 145.800 contacts WHEN NA1SS is NOT ACTIVE. Also clear out and don't interfer for the schedule ARISS school contacts. Enjoy our amateur radio. It is much easier to make a contact with you over the cross band repeater. Lets generate some interest and some use.

ps. I have been listening to the digipeater (TNC) on 145.825Mhz to know when the ISS is in radio range. It outputs a 1200 Baud modem tone every 20,30 seconds.
Maybe you have the TNC packet interface and can try a digipeat connection. Practice first with marginal earth bound packet stations. Good luck and enjoy this extra special amateur radio activity.
Usually one mode at a time
New to working ISS. But have read that usually one mode active at a time. Alot of packet activity on now. Voice has been 2-way with crew lately non-repeater.

Consider Working the crossband rptr when crew is busy or asleep.
I encourage other hams with Dual Band radios to try making contacts with other hams through the use of the repeater 437.800 Mhz up / 145.800 Mhz down WHEN the ISS crew is busy working or sleeping UTC 23:00 thorugh UTC 6:00 hours daily. I listened to a 9:17PM PDT ( 4:17 UTC July 12 2010 ) ISS pass over Washington / Oregon I heard no activity on 145.800 Mhz. I did hear the Packet Digipeater 1200 baud modem operational on 145.825 Mhz so I knew that ISS was in radio range. Some people did make APRS contacts and you could check the website to see http://www.ariss.net/ and http://www.findu.com/cgi-bin/find.cgi?N7OFW or http://www.findu.com/cgi-bin/find.cgi?W1AW

Again I want to encourage use of the Dual cross band repeater for voice contacts. i only have a two meter band radio Kenwood TM271a with a mag mount antenna on my car and would certainly enjoy listening to other HAMS ISS repeater contacts coming over 145.800 when NA1SS station is busy or sleeping. When I transmit direct on 144.900 and no one is operating the NA1SS station I hear nothing during that Pass. Yet if the crossband repeater was operational and hams with dual band radios were making contacts I could hear something during that pass of the ISS near my QTH. So yes this is a bit self serving, but I wish/hope to encourage more activity available for all hams worldwide.

Passing over Oregon at 4:34PM PDT local time.
Thanks ARISS for making Ham Radio contacts available from the International Space Station to a regular HAMS with minimal equipment and to the school children to encourage them.

Fred Finster I welcome other comments about using ISS crossband repeater when it is available.
