Hi Alf,

I also fly a vintage aircraft with no electrical system.

However I do have a Trig TT21 transponder with ADS-B out connection, Trig TY91 8.33 VHF radio and also a Horis 80 AHRS.

I power this equipment using a 12V 5.2AH Li-Ion battery which lasts at least 8 flying hours between re-charges.

So it is possible to be equipped with a transponders etc. without a full aircraft electrical system.

I am still undecided which way to go with having an electronic conspicuity receiver capability.

I like the SE2 but it can only detect ADS-B and FLARM. Also I would need to disable the SE2 Mode-S transmissions as I have a transponder.

PAW is on the list and will be interesting to see how the new MLAT capability works.
