Backup UHF, again…
-
Hello Forum.
I’m having a problem with the backup UHF in ramp start stage 4 in the first sweep. I’ve checked the steps up to that point in the manual and think that I have everything correct (?). I’ve also read the query posted by jc1 on Nov 7 (Backup UHF) and Red Dog’s reply.
So, CNI is in Backup, Comms 1 and 2 are set, left function knob in the UHF panel is in BOTH and the right on is at MNL. I want to enter the frequency into the manual frequency window.
Nothing at all, however, is displayed in the windows, no digits, nothing. I can rotate the five small knobs but nothing happens.
Please enlighten me or point me to the appropriate page in the manual, no doubt I’ve missed something.
(Also, and I don’t know if it’s relevant, but the 5 small knobs are not as crisply rendered in this TE as they are in others ???)
Thank you.
Bayonet.

Battery on?

Hi Sting, battery……yes.
I saw MAIN PWR and BATT as part of step 5.
I should have realised that the frequency setting section, while included in step 4, cannot be carried out until after step 5 BATT.Thanks again.

Did you happen to apply a model alteration like perhaps getting the pilot body for kneeboard? And um, you’re on version 4.33?

if your displays are blank, the BUP has no power

I beleive this has been solved guys. He didn’t have battery on.
