Which companies were the main suppliers for UHF, VHF and HF radios that were fitted on USN, USAF and army aircraft in the late 1960’s? Or to narrow it down, does anyone know which company made the radios for the Sikorsky S-61, when the type first entered service? Thank you.

The tech manuals I can find on-line for the AN/ARC-102 seem to be dated 1981.

Hi Terryham!
I hadn’t heard of 618-T3 before; seems to have been standardised as AN/ARC-102.
Were they fairly recent developments? Seventies perhaps? Seem pretty sophisticated.

I used to repair the Collins 618-T3 hf radio used in the Sikorsky ,a nice radio still in use today ,400 watts pep output ,frequency 2 to 30 mhz

And a little more info. The APX-6B was the IFF transmitter and the APA-89 was the back-end coded signal generator for it, according to this F-8 manual. Standard US Navy pairing it seems.

The AN/ARC-39 looks to have been quite a sophisticated piece of kit, with 12 preset channels in 2 to 9.1 MHz range. It could be operated remotely, allowing installation in a location inaccessible in flight.
According to this spreadsheet it was a Bendix product.

When I used to fix TACAN’s for a living, the ARN-21’s were made by Hoffman.

Here’s what I have from the Aircraft Characteristics for both the HSS-2 in 1961 and the re-designated SH-3A in 1967 ( no change in that period it seems ).
The mysterious ARN-21A ‘radio set’ is actually a TACAN.
