Over 600 pictures and videos.  Still didnt get everything.

Some are 200 megapixel.  12, 50 and 200 megapixel files.

Enjoy.  I hope to go back Friday before I leave to get the last room....  My phone died before.

Otherwise, I believe I have everything ya could see, easily.

Thanks; some good information there. I suppose I should get with the times and make use of some of those web-based AI's.
Since the A-4022-1 is a swinging choke, though, I'm doubtful that a modulation transformer might have been considered a "companion" piece, since a swinging choke is entirely a power-supply component. If it were a modulation-reactor type of choke, maybe, but I suspect that very few low-powered modulation lash-ups used a reactor.
When I have a chance, and my bench is cleared of current projects, I'm going to set to work mapping out that terminal arrangement and try to work out some of the ratios to get a better handle on this thing.

I did a walk through of the Kennedy 707. It was an SX-62. I had one at the time.

ChatGPT indicates that the A4022-1 is a swinging choke filter reactor so it would seem logical that the A4022 is the companion modulation transformer, but it found no specific info on it.

Here is some specific info on the A4022-1:

The Merit Coil and Transformer Corp A4022-1 filter reactor, identified by NSN 5950-00-578-8729, is a specialized component used in various military and industrial applications. While specific product applications are not extensively documented, its technical specifications suggest its use in systems requiring inductive impedance at audio and power frequencies, typically up to 20 kHz.
wbparts.com

Key Specifications of the A4022-1 Filter Reactor
Inductance Rating: 200 millihenries
Operating Current: 1.0 ampere DC
Mounting Method: Threaded stud (32 threads per inch, 0.138 inches in diameter)
Terminal Type: 3-pin
Enclosure Type: Fully enclosed
Dimensions: Approximately 2.688 inches (length) ? 2.312 inches (width) ? 2.750 inches (height)
Part Number: A4022-1
National Stock Number (NSN): 5950-00-578-8729
These characteristics align with components used in military communications equipment, radar systems, and other electronics requiring stable inductance and current handling capabilities. However, without specific product documentation, pinpointing exact applications remains challenging.

Columbine III not Columbine II

Someone else said it was an SX62

I missed the Delano decommission by a couple weeks.  I was pretty bummed.

I've been run off Delano by the local LEO a couple times.  Kern County Sherrif Office.  Not much they could do, we never went beyond locked or closed gates.  My son did enter the guard shack there, it was open and pretty empty, sans the last guard that left his COBRA paperwork.  It was over a decade old, but still had his personal info on it!  We trashed that.

The farmer to the south came out after my son and I where on his access road.  That got us about 100 feet from one of the curtain towers.

He told me if I wanted to I could use his road 'to hook up' to the tower to use it after he found out I was a ham. 

Never did find out whom I would ask for access to the feedlines though.




As to the receiver in question above.  No, it wasn't in Kennedys plane.  Thebone I am referring to was a flat face instead of rotary indicators for frequency.  Looks like a SX101 or SX140.

We have training classes through the week.  I fly back to the island Saturday.  I have over 650 pics snapped of the museum and my phone died in the 2nd to last room.....  with the missiles and air force one , etc.

Hopefully we get out around noon on Friday.  If so, I'll be up there Friday to finish my photos.  As it is, I have almost every single gle place and every single associated menu board type display.

Lots of receivers and transmitters, anything related to radio I tried to catch.

I have to pay for more Google storage.  I ended up  competent filling my Google drive with pics.

Hundreds of gig of pics and videos.  Should be cool if I do get to finish.  I hope I get to.

Edit.  It was on Columbine II. Eisenhower plane.

OK smart people, I know you are out there so lets hear from you! been working on this project and so far gutted the "B" set and removed it. The B set had a modulation transformer that was feed by a signal 6V6 tube running along at 250 volts on its plate. Figure that was good for maybe a watt or maybe two of audio. I would like to use that old modulation transformer that was in the VHF B set to modulate the 807 in the A set transmitter. The 807 chugs along with around 500 volts on it plate. It was screen modulated but been told the 19 suffers from piss week modulation so was thinking of changing it over to plate modulation. The question is will one 6V6 at 250 volts be enough to drive the 807 PA?
I do not care about power with this set and would be happy with two watts as long as its well modulated.
Any comments?

   At a small local hamfest this past Saturday, I came home with a couple of "mystery boxes" filled with assorted components and parts. It might seem odd, but I often deliberately hold off looking through the contents of boxes like that until I get home, because I enjoy kicking back in my recliner after the 'fest and exploring what's in there, with a couple of "save" containers nearby, as well as a "junk" container.
   Anyway, one of the boxes contained a very nice UTC S-19 modulation transformer, which will likely find a home in my next PW homebrew rig. Additionally, there was a similar-sized transformer: a Merit A-4022. With the "A" prefix and the fact that it shared a box with the S-19, I'm assuming that it's an audio transformer, although apparently some Merit television replacement transformers also carried the "A" prefix as well. I'm thinking that it's a "universal" modulation or driver transformer, given the eight terminals. I was only able to find three Merit catalogs on the web, dated 1951, 1960, and 1961, but unfortunately, none of them listed an A-4022.
   Has anyone ever come across one of these?

Had to abandon the rental in March, found a new rental in MA
but as I moved my business equipment in, they would not allow the electric to be turned on
and decided to auction off the property. So had to move all my stuff out and am now starting the search over....

Any donations appreciated. Steve

The Antique Wireless Museum in East Bloomfield, NY acquired the VOA transmitter and studio equipment from Delano California a few years back.  Here is a video that our President, Mr. Robert Hobday presented on getting the transmitter across the Country.   The transmitter and studio are now on display at the AWA Museum.

Start at the 17 minute mark on the video.
