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. https://www.youtube.com/watch?v=nsoSjh54a3A&ab_channel=IK5JRZThanks again.

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 ?

This situation doesn't happen in IARU R2, as 145.790-145.800 is a protection segment.
In IARU R1, there is no such a protection, suggest request change thru your IARU Rep.

Hello, I am very interesting to know how many peoples in the world have my, and not only mine..problem for receive ISS SSTV on 145.800. The problem is the repeater (7a) at 145.787.5 and ISS , for doppler naturally go down 145.800 and its impossible to receive well if someone talk on repeater. Thanks for attention.
