Portable Transponder ?
I guess if I Gargle it, or Wiki it I can find some answers, but briefly ... does anyone know of a 'portable' transponder that I can use in a Druine Turbulent (no generated electrical power ) microlight ?
I fly off an "unattended" airfield, i.e. no ATC in Class G airspace, but we have a mandatory broadcast zone for the benefit of the Dash 8 Air New Zealand commuter service four or five times a day, so no NORDO a/c are permitted, and I have rigged up a handheld radio with a fixed aerial and spare battery, but the zone is also Transponder Mandatory down to 2,000 ft. agl. so that Air NZ can see us on their TACAS gear, but their pilots are putting pressure on our CAA to lower the TM section down to ground level.
Unless I can find a small transponder to work off a battery, similar to my radio, then I will be permanently grounded.
Thanks.
