Anybody have any luck activating the 1269.65 MHz uplink or hearing anything on 145.800 from the L/v crossband configuration mentioned in this earlier story? http://www.issfanclub.com/node/8047
If so, what did you use or hear?

The ISS V/U crossband repeater is active, and works "only" with 67hz sub tone on
your 145.990Mhz (FM) uplink signal (otherwise no access!!!).
For the people who do not understand doppler search the ISS downlink signal between 437.809Mhz - 437.791Mhz (keep tuning with 5khz steps or less during the whole pass).
Check your transceiver manual how to make 5khz steps (or less).

I'm a new member, and viewed the frequency list, but
I wonder which is the "best" frequency ?
I mean, which frequency has the most voice traffic,
so that I have a good chance in hearing the ISS.
Thanks a lot,
HNY and Mry Xmas,
I was trying last 3 days to access the twist mode xband. Any one succeeded after the space walk?
Did you ever see Santas in Space?
Probably you will know them.
Look at this video: http://anon.nasa-global.edgesuite.net/anon.nasa-global/ccvideos/e18_holi...
It runs with the media player!

Hello to all.
I keep reporting that the crossband repeat is on, and everyone says it isnt.
I'm not making up stories!! hi hi
here is what i observed:
i uplinked on 145.85 with and without the 67Hz tone.
using 15watts into a quarter wave mounted on the vehicle.
The doppler effect was very evident, better audio without the 67Hz tone.
RX was on VX5 with factory antenna (holding at various angles) and rx on 437.805 - showing from s3 to s7 on the signal meter.
On high elevation (less distance to target) i could activate the repeater with 5watts.
I will try again on next pass here at ~0820hrs UTC (max elevation is 15deg for me)
Dou you have portable radio with 5w ? dou you want working on aprs via iss ?
you can forget please look on screen !!!
Many people transmit too many packets with very good antena and much power 50w....
Other stations with 5w and omni antena Can forget working via iss.73 sq3fyk
