[App_rpt-users] gtx900

[Bryan D. Boyle]

what he was asking is what hardware you’re going to use to receive @902 MHZ?  

The GTX is beyond being stone deaf at that frequency, so if you were planning to use one as a receiver, you will not be receiving anything.  

It’s pretty hard to build a cheap radio (and the GTX is a cheap radio, considering) with 25 MHZ of bandwidth between shared components on the board.

And I did put the dip switch close to the interfacing jack to off as specified. I then tried to do a radio tune rxnoise but it always fail. I want to use the dsp fonction of usbradio as it is way easier then getting a cor output on the gtx900.
