Re: ISS SSTV, Bandwidth

Hi Brad,

Since the ISS transmissions (SSTV) are coming from the Russian Zvezda module, using the Kenwood radio set to 145.800MHz, the APRS transmissions from the Columbus module are still active on 145.825MHz. If you have a SDR receiver/software running you actually see both transmissions on your waterfall at the same time. So, the ISS is receiving on 145.825MHz for APRS messages/contacts simultaneously. Two different radios, two different frequencies, one for TX only, the other one for TX/RX. Hope this helps.
