accidental satellite ops
I noticed yesterday while AO-7 was in mode B over the US there were several stations who were working the VHF contest this weekend. The downlinks sigs were LSB and obviously oblivious they were uplinking to AO-7. I emailed some of them, maybe we can create some accidental satellite aficianados.

Certainly word needed to local clubs, vhf clubs, contesting clubs about this anamoly. Indeed they are oblivious to where their signal is going and how. Too little attention is paid to band plans. Good snooping Bob.
See you soon on the birds.

Actually Larry that was the band plan back in 1974. Who would think we would still have it 35 years later. The satellite is older than many the the ops. Looking foward the the "rebirth" of AO-40 (sobsob).

I heard this during the ARRL UHF contest back in August as well and found it amusing. They are correct, though, and not violating the bandplan as the AO7 uplink is in the weak signal part of the band-that is what happends when your satellites lives for 35 years-band plans change
It would be nice if some of these stations discovered that their terrestial equipment will work fine on the satellites, that is how I became an accidential satellite op.

maybe the best one can do is to send QSL cards noting the time/freq/sat/mode to the ops. Of course this assumes that their callsign can be understood

The primary problem is that the OSCAR VII inputs are now in the weak signal portions of the "band plans". With the proliferation of FM activity the weak signal portions have been compressed. It is unrealistic to even think of "blaming" the weak signal operators for interfering with OSCAR VII operations. Remember, OSCAR VII is 35 years old and was not expected to be in service for more than just a few years.
One should just be happy that OSCAR VII is still usable and work around the occasional situation with unintentional interference. Besides, there are not that many contests on the VHF and UHF bands and most of the time there is little activity in the weak signal portions of 2-meters and 70 cm.
As for garnering additional satellite operators that is definitely a possibility. However, I don't know how many new operators would actually be recruited.
