It is always the same . . .
In SSB mode we can send CQ.
In FM mode the first rule is "if you can't listen NO TX". The problema is that SO-50 no TX if no listen to somebody, so people when can`t listen they think that they can't be received by the sat.
SO-50 is a specepial case that we will see more frequently on the space. It is the subtone system colateral damage.
But if most of us know that the sat is usually collapsed or at least with moderate trafic, it is a reasonable way no call CQ. So my advice:
- First of all listen, if there is some station that fit your log, call him.
- If you decide to call, the best way is only your call EA4CYQ/P or EA4CYQ handheld.
I think your locator it is not neccesary until you Exchange data. When you made a contact, you send your locator and the rest oh hams will listen it.
It is a pity listening to Yuri (/mm) calling on a FM Sat from wet grids and other station, which clearly can´t listen him, calling CQ killing the chance of any QSO.
To wrap up:
- If no listen no TX
- CQ only in SSB sats
- In FM SATs, your callsign is enough to advertise of your presence.
