[REPORTED]Selecting previous radio channel not working.

As far as I know, if you press COM1 or COM2 on the ICP followed by ENTER without inputting any numbers, the selected radio should switch back to the previously selected frequency or preset. This is currently not working.

Here's the track.

This is the info I have:

 

 

This is how I see it working, If you don't type in anything new, then the previous frequency or preset is selected, which happens to be the current one. It seems like a correct function for the scratchpad.

I understand what you mean, but I think you misunderstood what I meant in relation to the quote you posted. In it's current implementation it doesn't select your previous freq/channel you had in the scratchpad. Instead it displays the current freq/channel which makes no sense. Why would I press ENTER to see the freq I'm already on? I have no IRL F-16 experience, but the way it works in other sims I've played this feature allows me to quickly return to my previous channel without having to input anything; just press COM1/COM2 followed by ENTER and you'll be back on your previous frequency. Do the same thing again and it will return to the freq/channel you were originally on. In its current implementation in DCS this isn't possible, as it instead tries to enter my current freq/channel and I just stay on the same freq/channel as before.

EDIT 2: I checked again just to be sure I wasn't talking out of my ass, and there was an slight inaccuracy on my part. Actually, when you press COM1/COM2 your scratchpad will show your previous freq by default, not the one you're currently on. So if I switch from 251.0 to 255.0, then the next time I press COM1 my scratchpad will display 251.0 even though I'm on 255.0. If I then press ENTER, the next time I press COM1 I will be on 251.0 and the scratchpad will display 255.0. I'm tired and possibly retarded. I'll be back tomorrow to triple check my claims lol. :music_whistling:

Input: COM1, 1, ENTR

Expected result: Preset 1 tuned

Actual result: Preset 1 tuned

Input: COM1, 2, ENTR

Expected result: Preset 2 tuned

Actual result: Preset 2 tuned

Input: COM1, ENTR

Expected result: Preset 1 tuned

Actual result: Flashing scratchpad

This behavior would match expected behavior if upon changing COM1 tuning (new value is different than old) it would save the old value. When COM1 page is next displayed the scratchpad should initialize with this saved old value.

I've tried to find a single condemning sentence in all my handbooks but there is nothing that explains it beyond the shadow of a doubt. Everything seems to point towards it, but I don't have definite proof. The closest sentence I found was the exact same that you quoted NineLine.

One interesting thing though is that in my handbooks I can't find a single picture of the DED in COM Override Mode that has an empty scratchpad, and there is not a single illustration where the scratchpad frequency is the same as the selected frequency.

I also found this illustration through google images but I can't for the life of me find it's source, and therefore I can't claim it as definite truth. The illustration does however show the exact behaviour that I tried to explain, which Frederf explained more eloquently than I ever could.

If I tune channel 19 and then later tune channel 20 then channel 20 is the current tuning and channel 19 is the previous tuning.

When UHF page is initialized there would be a "20" in the position showing what the radio is tuned to right now and a "19" in the scratch pad.

By simply pressing ENTR then the scratch pad value is submitted without the need for pressing ICP-1 and ICP-9 first.

This is how I see it working, If you don't type in anything new, then the previous frequency or preset is selected, which happens to be the current one. It seems like a correct function for the scratchpad.

If you do not type anything but just press enter the former freq OR preset is selected. So for example:

Pilot needs to switch from COM 1 preset 1 to preset 2. He pushes COM 1 priority button, push 2 on the ICP and than enter. Now COM 1 is set to preset 2. Now he tries contacting an ATC agency on 2 but do not get a reply. To switch back to preset 1 he pushes COM 1 priority button again..push enter and COM 1 will revert back to preset 1 (without pressing 1 on the ICP) .

Same goes for frequencies.

I reported a related issue in the past which has since been fixed, yet one issue still remains. When you press COM1 or COM2, the scratchpad should show your previous frequency (doesn't work). Then if you press enter without inputting a new frequency, it will tune your previous frequency (works). I've linked my previous report below.

Here's a video with a timestamp at 35:30 where you can see this in action. The pilot presses COM1 and you can see preset 5 already being in the scratchpad (if you rewind to earlier in the video you'll see that it was his last tuned frequency). Then he overwrites it with his intended preset 7 an tunes that instead.

The functionality is also explained in the M1 tape Pilot's Guide under paragraph "Auto Exit Feature".
