SpaceCam1 SSTV repeater sites

During the testing phase, SpaceCam1 repeaters will be active on several 10-meter frequencies.  MAREXMG encourages amateurs to use them, and to report any unusual behavior to the repeater operator. The table below shows the latest status of all sites.

*The N7CXI repeater will be put back on active status as soon as work on the dedicated repeater antenna is completed.

**The KA2HZO repeater will be active 1900-2300Z.  Beacons will be transmitted every 10 minutes.

SpaceCam1 repeater access instructions

• Listen first, to make sure the frequency is clear.

• Identify on SSB.

• Transmit a 1750-hz tone, for approximately 2 seconds. (see your SSTV program documentation)

• Switch to receive mode immediately.

•  If SpaceCam1 hears your transmitted tone with at least a 10db signal-to-noise ratio, it will respond with a 'K' in morse.

• Send your picture immediately.  SpaceCam1 repeaters will always respond to signals transmitted in Robot 36 mode.  Other modes may or may not be enabled by the operator.

• If SpaceCam1 successfully receives your picture, it will re-transmit it in the mode you sent it.

Notes

• SpaceCam1 version 1.1 will transmit a DTMF (touch-tone) tone before identifying, then re-transmitting the picture.

• Currently, SpaceCam1 repeaters are being operated in low-security mode.  Testing schedules for secure operations will be posted here in advance, to avoid confusion.  The option SSID is not required at this time.

• If you don't get a response from the repeater when you send a tone, please do not transmit a picture.  You may cause interference to another station the repeater can hear, but you can't.

Thanks to Wayne, N1WPN and Ron, KA2HZO for their willingness to tie up their equipment and time.  --Jim
