Hi Claudio, The Reflector seems to be having trouble relaying my messages. Let's see if this one gets through . . . Covering each point in turn: 1. - I would not find it useful, as I use existing out-of-band signals to check my receiver, etc. 2. - The disadvantages of beaconing within our tiny amateur allocation have been well-documented via this Reflector in the past. If you must do it, the extreme band edges are to be preferred (135.7-135.8 and 137.7-137.8). 3. - The greater the period of operation, the greater will be the probability that the beacon will cause QRM to local stations. 23:30 to 04:00 UTC seems like a reasonable compromise.
