I've recently installed version 4.2 of the 757 for FSX, and I've encountered a peculiar problem - I cannot seem to tune any of the COM radios on the radio stack. I cursor over the tuning knob, as well as the frequency windows, and get the usual + and -, but nothing I do will change the frequency. I've tried numerous times, with the aircraft in a fully powered state.

Has anyone else encountered this issue? Any ideas on what may be happening?

Thanks for any tips.

The man/auto button is only on the NAV radios...I am having the exact same issue. unable to tune radios. This is following a clean install and using the FSX default flight situation. Any help would be greatly appreciated.

FSX Acceleration, and unregistered (limited) version of FSUIPC..no other addons.

Hey Bruce,

So, your issue with tuning the radios is now fixed? All you did was reboot? Please let me know if there is anything else you did in addition to this. I've rebooted many times.

My issue still persists. I have a ticket open with Support, and so far, they've asked me to re-install FSX SP2, which I've done. Still no luck.

As an aside, I also have the violent rocking side to side issue that's been mentioned a few times in this forum. Happens every time a switch on the autopilot.

Looks like I might be "shelving" this sim again. I've been over a year trying to get this 757 to work well enough to complete a flight. Quite a shame, since it looks like it has great potential.

Thanks in advance for any other tips anyone can offer.

Bruce, you rock!

Believe it or not, I did *not* think of loading up the 757 by starting the default flight first.

I just tried this - I started my FSX default flight (in my case, a Cessna Skylane ready to go on Montreal's active runway), and then I changed aircraft to the 757. The radios were tunable!

Now I haven't tried to switch back to my other flight, or try to create a new one, so this is what I will try next. However, this is progress!

Unfortunately, I still get the violent side to side rocking motion when I turn on the autopilot, but that is another issue being discussed in another thread.

Thanks very much for the excellent suggestion Bruce. I'll now see how much further I can get (without the autopilot) and what new issues I run into. I haven't encountered the sound issue you mentioned yet. Good luck with that.

Cheers.

Make certain your Avionics Master is switched ON with another aircraft first, or bind a key to it in the controls section of Options->Settings.  This is likely the cause.
