I have a chance to install a 136 kHz QRSS beacon in ARI Milano radio
club (north Italy).

Before to propose the project to radio club I ask LF peaple for some
1 - This beacon may be useful?
2 - If yes, what frequency may be preferred?
3 - The choice to start beacon at sunset and stop it at sunrise may be a good choice?
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.
Regards to all,
Steve GW4ALG
