COMM Squelch Switches and Warning Speeches.

[Devrim]

Hi...

At COLD START, this is what I see on COMM panel.

Naturally I can't hear warning speeches well and I crank up the Master Volume.
At that moment I hear too much white noise comes from squelch channels.
I get rid of them by pushing SQL switches "up".

BUT! If I sit the cockpit with HOT START, all SQL switches up and I can easily hear warning audios.

Is here correct as is?

I mean, when a switch is down position, shouldn't it be OFF?
In Apache, these switches are working in opposite way?

Thank you!

Squelch manages a radio's audio so that you don't here the raw audio static unless you get a minimum level of radio signal (very basic explanation that probably isn't accurate, but I'm being lazy).

So when squelch is turned down or off, you will hear a radio's raw audio output continuously regardless of the presence of a strong radio signal being received.

Having said that, the current implementation of these switches is not correct. They should be springloaded to a center position, and are "bumped" forward to toggle squelch on that radio, or bumped back to remove it.

The reasons these switches should work this way (which is accurate to real life AH-64Ds) is because there are two switches for each radio, one in each cockpit. If the pilot has the VHF squelch switch turned off but the CPG has it turned on, what switch should be correct? So the switches are just bumped in a direction.

Ah! I got it Raptop9. Thanks so much. I missed the working logic of SQL.

Now it makes sense.

About switches, you're right. In manual, it says "momentary toggle switches" but it's not in the sim.

OK... Well, thanks!

No problem, glad to help out a member that has contributed a lot to the community in the past.

Oh! Thanks man, and you're welcome.

So what is the procedure now during Cold Start?
All the SQL switches up?
I found it that the radio is silent with master volume to 50% and switches downduring the training mission, but when I want to do Cold Start anywhere else, I get static noise - and mowing the switches up helps...

Apparently the real apache has the squelch switches spring loaded to the center position (because there is a set in each cockpit and they both control the same radio hardware). Squelch should be on (up) or you get raw audio in your headset from all 5 radios.

I think right now it's incorrectly implemented. But yes, put them up.

Thanks!

Thanks! This explains why the CPG radios are already squelched while the SQL switches are in down positon when I squelched the PLT radios before on a cold start procedure.

Ok so I have been through the cold start training many times and have pretty much got it down pat now. So I loaded up a cold start mission in instant action in the Caucasus. I proceed through the cold start turning master volume to 50% as I was trained to do. However in this mission I get this extremely loud squelching sound in my headset. What in blazes is that? It is way louder than even the APU. I have to turn master volume all the way down to get rid of it before it blows my ears out.

You have to flip up all the squelch toggles above the volume knob

You need to turn on all the squelch switches:

Ok much thanks guys!

I have the same problem. My thread has been marked as solved; Raptor did a good explanation, but actually that's not a solution.

Try moving the master volume knob away from "MIN". Shouldn't work, but seems to.
