solved Mi24 search and rescue with ARK U2 & R828 not working

[DST]

I set up a training mission with a unit sending emergency signal 50 Mhz FM with sound file on loop, and want to catch signal with r828 radio. I followed every step from chuck´s guide, but don´t get any signal from ground unit. Works fine with Huey and Mi8 but no success with Mi24. Mission is attached below. Is this bugged or what do I miss?? Preset channel 7 for 50 Mhz is supposed to work, is it?

It works fine, you are probably missing some step.

Save a track file and post it.

It works for me. There is some message in Japanese (?).

My checklist:

I have noticed that the label for SPU-8 is misleading:

R-828 is the third setting, not the fourth. It's just the mouse hover label, the English cockpit is fine.

Yes, the ogg. file is japanese bingo from F16, I couldn´t find different file for use

What is "radio trigger" on the cyclic? There is nothing like that in chuck´s guide?

First stage is ICS, second stage is radio. That’s what radio trigger does

You don't need radio trigger for this to work.

Obviously the trigger is used for transmitting and not jut listening to the frequency, I thought it's rather self-explanatory.

@DST Have you figured out what went wrong?

[randomTOTEN]

Just tried the mission, and it works for me.

OK, thank you for the anwers, turns out, I did not press the "squelch" button long enough

What I find strange though is, there seems to be either audio signal or compass needle pointing, not both at the same time. If ADF-VHF 2 Source Selector is in the middle you get audio signal but no HSI needle pointing, when ADF-VHF 2 Source Selector is in FWD position you get no audio signal but HSI needle is pointing in the right direction. In Mi-8 you can get both. Is this supposed to be like that in Mi24?

From reading Mi-24V manual book 1 dated 1987 this seems to be the case. Intended procedure is to heat audio signal first using SPU-8, then switch to COMPASS for guidance to the beacon once you hear the correct audio signal

Yes, it took quite a long time (holding the button) for the radio to change channel. Because it had to cycle through 6 channels to reach 7?
