I have a transceiver working in the 435 MHz ham band. I want to test my uplink capability by communicating with satellites operating in this band.

Are there any digital satellites which I can use for this purpose?

  • $\begingroup$ I saw the page. I did not get exactly which satellites from the list are available for uplink in the 435Mhz range.It just mentioned the status of various satellites. $\endgroup$ Mar 24, 2015 at 13:00

There certainly have been satellites using 435 MHz uplink: for example, STRaND-1, in which I had some minor involvement, used 435 MHz LSB. I don't believe we had an unencrypted uplink capability, though - however, you may well find hamsats that have.

The satellite went quiet fairly quickly, but if you do manage to receive any telemetry from it - it did wake up again for a while, so this is not impossible - the team and I would be delighted to hear!


From Amsat UK:

Fox-1A frequencies, see Operating Guide to set up your rigs memory channels:
435.180 MHz FM Uplink 67 Hz CTCSS PL tone required
145.980 MHz FM Downlink
Note: If your rig has selectable FM filters use the wider filter for 5 kHz deviation 25 kHz channel spacing.
