The SSB uplink and UHF downlink transponder fits on a
smaller than 3x3 circuit board
I presume the reason for UHF downlink rather than
145 MHz, with it's lower Doppler shift, is due to
other mission constraints ?
Yes, avoid QRM to the 145.825 APRS transponder.
BTW is the uplink in the amateur satellite segment
of 10m (29.3-29.5) or down at the bottom of the band ?
Bottom
Hey Bob,
This might also be a great project for balloon launches as well, to be able
to test all the ground station setups.
Any idea if these transponders will be made available to others after this
project is completed ?
It appears that the Small Wonder Labs' PSK device is no longer
