S5, LY, EI, OZ, and ZS licensed hams have 8-metre-band allocations (40660–40700 kHz). The rest of EU can use that ISM range without a licence provided erp≤10 mW. If, outside those countries, we experimented FT8 at 40680 kHz using 10 mW and used our callsigns as handles (after all, we could be called anything there), would QSOs with these countries be possible in Es season? Or would that be a breach of our licences?

@Ea5iyl I'm inclined to think that (as an EI ham) I would be in breach of my license if I replied to you.
From the ITU radio regulations:

Definition of the amateur service (i.e. purpose): A radiocommunication service for the purpose of self-training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorised persons interested in radio technique solely with a personal aim and without pecuniary interest.

@Ea5iyl

By my reading., even if you (as an EA) were to use your EA call, the 8m band isn't part of the Spanish Amateur sevice, you're just using a handle that happens to sound like an amateur callsign, there fore, I, in EI, cannot contact you because, in the 8m band, you're not an amateur (ie unlicensed).

Don't know if what you're doing is legal or not however

@eamoEI7LC I think you're right, thanks for the clarificatio.

The general rule is that #hamradio amateurs may, via hamradio, only contact other hamradio amateurs. That's the German situation, but I think it is the same pretty much everywhere.

While I were using ISM permissions on a non-hamradio frequency (given my administration's rules), I would not count as a hamradio amateur. (Personally, I would also hesitate to use my hamradio call.)

So I think it would be illegal for an EI ham to contact me (unless with ISM stuff only).
