Airborne radio may hinder 144 MHz ham radio Sweden's national amateur radio society, the SSA, has written again to their regulator, the PTS, pointing out the interference the Aeronautical Mobile Service would cause to amateur radio A translation of the SSA post says: New letter to PTS. These days, SSA has responded to the invitation to comment with another letter to PTS. Here, SSA proposes that PTS should not support the proposal in accordance with EUR-B10-2, as long as 144-146 MHz is included. This became necessary, since the latest text in PTS documents does not include the proposals previously submitted by SSA. Much of our traffic is about receiving signals in and around the noise floor. Radio traffic at the same time as that from air-based radio, which normally uses high-radiating antennas at high altitude, thus becomes impossible SSA writes. We therefore want PTS to propose that the band 144-146 MHz be removed from the proposal for coexistence with airborne broadcasts. Mats SM6EAN, who is SSA's section leader for VHF / UHF / SHF and IARU, gives a detailed account of the matter on our section pages https://www.ssa.se/nya-skrivelser-fran-ssa-och-iaru-infor-wrc-19/ Here you can also go ahead and read the latest letter to PTS and other documents in the case.

Would not the interference problem work both ways? Hams might not be able to complete a QSO. Aircraft would face a more serious problem.
