June 27, 20223 yr Hi guys, I use a set of Flight Illusion Bendix radios alongside a RSG 750 with the TDS 750 XI... I am noticing an issue with tuning radio frequencies...basically on some airports I can't as they are using fractions I cannot get...like 121.23...If I put that into the 750 it defaults back to 121.20... The only way I can do it is to use the in sim ATC which spoils my immersion.. Dave
June 27, 20223 yr Commercial Member Is this due to the radio frquencies (and thus the radios themselves) changing from 8.33KHz change from 25KHz?

June 27, 20223 yr Author Yes, That must be it... Does that now make all our expensive after market hardware obsolete? Dave

Probably, which is a real bummer, but think of what it must cost aircraft owners to replace their radios... Hopefully a software fix is possible to create a workaround.

June 27, 20223 yr I would expect that any modern hardware (within the last decade or so) would work with 8.33 khz. It isn't a modern change really..can't remember how long ago, but they have been cramming frequencies in that space for a while now. Ryan is probably correct as usual.
