The Shark ID is currently sent by keying a carrier on/off, other hotspots send a carrier that has an FM modulated keyed tone that is easy to copy on any hand held.
While there is little point in transmitting ID on a unit that radiates no further than a car remote locking key, if necessary for licensing purposes can the Shark ID be changed to a mode that can be heard on an FM hand held?

The currently transmitted unmodulated carrier wave satisfies regulatory requirements.

The currently transmitted unmodulated carrier wave satisfies regulatory requirements.
It might well do, but as a seasoned ex professional Morse operator, even I find it hard to work out my own ID from a Shark using an FM hand held...

Don't think MCW is possible using the ADF7021 modem, it's not intended for analogue modes.

There’s an ADF7021 in my MMDVM hat sitting on a Raspberry Pi, running under Pi-Star. That sends FM MCW which sounds fine on an FM handy.

I have 3 Pi Zero Ws with HS_HATs, but I've never enabled the CWID.
I suppose I should read the code to see how to do it, have to say that the ADF7021 data sheet doesn't say much about non-FSK modes.
Ah, I see what has been done, they use 4FSK to simulate FM deviation by stepping through +1, +3, +1, 0, -1, -3, -1, 0 offsets. Apparently Andy that writes the modem code did this about 18 months ago.

In beta v48 the MCW CW ID works fine, great news!

Good news. At least that should make those that care happy.
