Rockwell Collins 718U-5M avionics HF SSB transceiver (AN/ARC-174)

[@turnleft_]

Had the distinct privilege of working with this radio in the US Navy, SH-60B helicopter as an avionics tech. Back in the day, KC9CFI... I would take every opportunity to get out and play with this radio back in the day when I could get away with it!

Thank you for your service!

I've never seen an HF aviation fit running outside an aircraft before. Great work in getting it running.

Thanks for showing us this - it's great to see this HF gear which is not seen often!

[@timforrestcet35]

Very nice video...Thank you, Sir! Brings back many avionics memories.

[@ricardosuarez8023]

What a great piece of electronics! Very advanced for the time it was made. Thank you for the review.

I operate a Falcon 50 (See my QRZ page, K7KSG) with a dual installation and have had both out twice for repair and they still will not tune. Sadly, there are no avionics techs around who know anything about HF systems anymore. That being said, I certainly enjoyed your tour of the radio components; I couldn't ask for a better guide. Thank you!

I worked for an airline in avionics.Its hard to be an expert when we work on so many systems,different aircraft. We had a lot more problems with the antenna couplers,tuners that is,receivers,panels were much more reliable. All were Collins.

Really cool, expensive & rare. Neat set up.

[@dang25272549]

Wow... very nice and unique radio . I guess it wasn't easy to put everything together and make it works. 🖒🖒🖒🖒

[@robertrockwell7581]

very neat radio it takes up a bit of space.

[@rogerhitchner6962]

What microphone do you believe would recreate the Rockwell Collins snarling audio effect ? The Telex 66T you mention or another ?

[@flyer617]

Now I just need to find one for my plane.

[@gianpietrogozzi1983]

please please please. I'm looking for the connections between RX/EXITER and PA of this rig. can someone help me? Thank you

[@LifeIsTooShortForQRP]

Give me an email address then I will mail it to you

[@radio655]

Beautiful. How to get it into the avionics bay of your car?

[@LifeIsTooShortForQRP]

That would need a DC to DC converter from 12V to 28V. I actually bought such a DC converter ( a military one) that can handle the needed current, from this guy: www.ebay.com/itm/351720076674 This radio will actually work quite well mobile, you could mount the control box on the dash and the radio itself in the trunk, and the built-in antenna coupler can match a vertical on the car automatically for any selected frequency!

wow never seen anything like this lol, wow awesome

[@VK2UAL]

I love that radio, I have always wanted an airliner Hf TX RX I would like to know did you have much trouble tracking it down ? I been looking on eBay and the like but not as yet. Keep up the great work, it is greatly appreciated. Regards Richard vk2ual

Keep an eye open now because civil aircraft are being scrapped like never before. Old HF radios will not be taken back into stock. They probably scrap them to recover the gold.

[@proudsnowtiger]

No conformal coating?

[@LifeIsTooShortForQRP]

Yes, the boards are all coated with some kind of protective varnish. Doesn't show on the video too well unfortunately

[@dang25272549]

So cool !👍

[@ngawairangi3694]

Any cb radio side band For sale how much

[@maninthevan53]
