[amsat-bb] R: Re: ISS SSTV frequency

[ik5jrz at tin.it]

Thanks for answer,
The repeater is R7a (Monte Secchieta), it's not only an Italian problem unfortunately, I have read many complaints in other areas as well. I don't question the correct spacing between frequencies, but I'm afraid it's only on actual paper. I don't want to doubt that the repeater is working correctly, but I think that if the ISS transmitted at 145.825, since when it transmits in SSTV APRS is disabled, the problem would be solved. The video demonstrates the proximity between the frequencies even if I admit to being in the high area and to receive the repeater very well.

Ogg: Re: [amsat-bb] ISS SSTV frequency

According to the band plan reported on the ARI web site, the space
communication band is protected starting at 145.794 Mhz, i.e. 6 Khz below
145.800 Mhz. The R7a is indeed at 145.7875 Mhz with a bandwidth of 12 Khz
there shouldn't be any interference (in theory). Have you checked which
repeater is in your (our) zone ?
