Missing Radio

All of the CH-47F communications are fully integrated into the avionics, and controlled through the CDUs and MFDs. The single radio control panel on the center console is a backup control head that allows the crew to control the ARC-186 VHF radio if there is some sort of failure in which the CDUs and MFDs are not functional.

When the ARC-164 UHF radio was added, its functionality was added to the avionics (referred to as U2, since it is the 2nd radio in the stack), but there is no physical radio control panel for it.

You can interact with it through the CDU by pressing the CNI button, and cycle through the various radios on the main MFD using the Radio Freq switch Left/Right on the Thrust Control grip.

i wonder why  a circa 2011 ch47f even has arc164? Its an old radio. According to forecast international the last unit was delivered in 1994 . its Just interesting because in contrast even the analog Uh60L's and Ch47F's processor, the CH47D replaced Arc164's for ARC 220's by early 2000s. is there any reason to keep arc 164 as an additional backup radio? instead of just having another pair of newer radios? Honestly surprised a radio of that generation could do away with analog control panel and be fully digitally integrated to be instead accessed via MFD/CDU.

@Kev2go, the ARC-164 is a reliable radio that is still in service to this day across multiple branches of the armed services. Just because it is "old", does not mean it needs to be replaced. If it isn't broke, don't fix it, and reliability and maintainability sometimes outweighs sophistication.

The ARC-220 did not replace any ARC-164 radios. The 220 is an HF radio intended for non-LOS/over-the-horizon communications. It's not a UHF radio nor does it operate anywhere close to the same frequencies.

These types of radios have been integrated into the digital controls of many different aircraft for decades. The F-16C and AH-64D also include the ARC-164 as their UHF radio, which are integrated into their digital avionics. Like the CH-47F, the ARC-164 is only accessible through the AH-64D avionics and does not include a physical control panel. The F-16C does include a backup control panel for it in the cockpit, but the radio is otherwise controlled through the upfront controls like the AH-64D.

IF i compare 1980s Ch47D or UH60A manuals to thier 2000s publications i see an arc 220 in the place of where 1 of the ArC 164 panels used to be.

ARC 210 which is installed A10C II is UHF no? and its primary radio. ARC 164 is only left as a backup. the older A10C had ARC 164 and some other older radio which i cant remember.

Uh60M doesn't seem to have ARC 164. Only recall the manual citing Arc201D and ARC 231 radios. Ah64D we have is circa 2005-2008ish. ARC 164's replaced by ARC 231's in the first AH64E's in 2012. Not sure if refitted to Ah64D blocks as i don't have newer publication to personally reference or verify.

The F16C is from an earlier timeframe then the in game chinook its supposed to have ARC 210 radios, they were being fitted around suite 4.2 and onwards but for apparently ED chose older ARC164 due to lack of documentation  of ARC210 integration within that specific platform. F/A18C iirc have  2  ARC210s.

The panels within some of the helicopters may have been rearranged over time or when the ARC-220 was added. But as I said, the ARC-220 is not a UHF radio nor did it replace the ARC-164.

The ARC-210 has no bearing on this conversation. It was about the ARC-220, which cannot replace any VHF or UHF radio as the 220 cannot be used on those frequencies. The 220 is HF only and serves an entirely different purpose than any VHF or UHF radio.

AH-64D's use the ARC-164 to this day, along with many other aircraft in the armed forces. As for the rest of your comments about years and timeframes, I don't understand your point. In response to your earlier statement about being surprised that an "old" radio could be integrated into digital avionics, I was providing some examples of the ARC-164 being integrated into digital avionics going back to the 1990's, and that it is not as uncommon as you might think. The only difference is the electrical controls to the radio "box" are sent from the avionics, rather than a physical radio switch or knob.

disagree. it was about various radios seemingly being replacements of the ARC164 not specifically about the 220. i mentioned the 220 because thats what helos didn't initially have that and i thought it was analogous to how other aircraft like A10 only retained Arc 164 as backups or how in other platforms entirely replaced ARC 164 for ARC210's . 

For helos i guess i was wrong about the 220 since its HF and it seems the UHF & VHF replacement is the ARC 231 in rotary wing department.

Oh ok US army didnt convert all AH64D's to AH64E's.

that was just thinking out loud.

It looks like the arc-232 will be the replacement for the 164 it’s the same guts as the 231 but in the footprint of the 164. Looking into it they didn’t start producing the arc-232 until around 2008 timeframe so after we started buying ch-47fs so maybe the block 2 have them but probably correct for our version not to have it.

arc 231 is present in the CH47F block 1. its the radio that makes use of the satcom antenna which is there on external 3d model. ITs just the Ch47F does still retain 1 ARC 164 ( U2). ARC 231 is the 6th radio according to the operators manual.

I'm also having issues with the thrust grip radio hat switch. I'm seeing it move (on the actual trust grip) when I push my mapped button but nothing changes on the mfd. What am I missing?

 

With so many current module bugs it's difficult to determine what is a bug vs what is a feature. But hey everything is in stable release and no more open beta! 

That last sentence is sarcasm BTW...
