AMSAT pminner om at ven FO-29 och SO-50 gr att anvnda fr katastrofhjlp:
Please let your contacts in the affected regions know that, in addition to AO-51, two analogue transponder satellites are available 24/7 to help with disaster traffic: Fuji-OSCAR 29 and SaudiSat-OSCAR 50.
For those who are not familiar with them, FO-29 is a linear transponder that will reproduce whatever is uplinked to it, with one difference: due to its inverted passband, a USB uplink signal will be downlinked as LSB, and vice versa. The uplink passband is 145.900-146.000 MHz, and the downlink 435.800-435.900 MHz.
SO-50 is an FM repeater in the sky, much like UO-14 (now QRT) which was so helpful in previous Indian disasters. The uplink is 145.850 MHz, the downlink 436.795 MHz. Unlike UO-14, however, it requires a PL (CTCSS) tone for access. If you hear the satellite operating, use a tone of 67.0 Hz. If it is in range and you do not hear it, you can turn it on for 10 minutes by transmitting for 1 to 2 seconds with a tone of 74.4 Hz, then switching to 67.0 Hz for operation.
In addition to FO-29 and SO-50, two satellites are also available on a part-time basis: AMSAT-OSCAR 7 and AMRAD-OSCAR 27. Consult the Sat Status page on www.amsat.org for further information about them.
Hope this helps.
