Sailplane equipment: transponder, transciver 8.33 kHz.

I'm searching for the cheapest SSR transponder and transciver with
8.33 channel separation that could be mounted on a sailplane.

Mode S transponders cost in the range of about $2500 to $2700. There are
several manufactorers, all more or less in the same price range
(Garrecht, MicroAir, Funkwerk, Becker...). You need a level 2, class 1
transponder, be sure not to confuse level and class!

As far as I know, there's no need for a glider to have a 8.33kHz radio
anywhere in Europe. 25kHz radios cost in the range of around $1300 to $1700.

Of course prices may vary and depend on exchange rates.

Yes, but flying on the same attitude as airliners requires from
sailplane similar comm. properties.

So I guess... that 8.33kHz radios are in the range of 4-7k USD?

Any chance of buying working stuff from second-hand? Don't You know
any reliable firms/companies?

I'm not convinced, I've been given pretty high clearances.

Anyway, prices seem to have come down. Funkwerk e.g. sells the ATR833
for 1700 Euros (ca. $2050): http://tinyurl.com/2wu78ps

Be sure to look at the Trig TT21 Mode S transponder - more like $2000 -
and with some ADS-B out capability.

Again: Make sure the transponder is class 1! The TT21 is class 2.

BTW: Most transponders are "ADB ready". Whatever this means.

Ok, thanks for Your help.

True, but you can get the Trig TT22 which is class 1.

True, but you can get the Trig TT22 which is class 1.

And which, incidentally, seems to cost around $2400.

Gasp - something that has more performance costs more? Who could have
guessed? Anyway, it's still below the range of $2500 to $2700 that you
quoted above...

Actually, I just did a very quick and very dirty net search. Everybody
knows that prices vary, that comparisons between European and US prices
are difficult and that there are also such things as sales tax, shipping
cost etc.

That said, I don't doubt a moment that the TT22 is a nice instrument.
Just compare before you decide. E.g. when I find two instruments with
the exactly same capabilities but one has a better user interface than
the other, this alone may be well worth $300 to me. As always YMMV. (Of
course I don't say that the TT22 has a bad interface, as I've never seen
one.)
