70W transponder, valid for use above 15,000ft?
In post 84, cats_five suggested that I should ‘Check the manual for the TRT800H’, but did not give its output.
I had referred (in post #83) to the CAA’s suggestion that a number of transponders on the market produced ‘a peak pulse power of 70W and appear to be suitable for use in many types of glider’. I asked if those transponders gave an adequate signal above 15,000 ft.
I had in fact checked the TRT800H before posting. It is indeed good up to 35,000 ft. But its output is 250 W (125 W at antenna), which is a fair bit above 70W. Gliders really need a LPST.
So I’m still looking for a 70W transponder, good for use above 15,000 ft.
