Hallicrafters BC-610-E WWII AM Transmitter Restored Pearl Harbor and Battle of Midway

[ray89012]

Brings back memories when I used to operate one of these. It almost killed me when the filament transformer shorted and put the 2,5 kV on the case. I got between it and a radiator. I blew the 30A mains fuse and woke up a few minutes later. Be careful and ground the case.  WA2JRE

Nice restoration and presentation! It's been decades since I've seen the haunting glow of 866s. de Mick - WB4LSS

Cool!

Yeah 'vacuum state'! MOSFETs are boring.

3 RF amps, since you are dumping that into a 50 ohm load:

3^2*50=450 watts.

what a beautiful radio! are you saying that is the actual radio used at pearl harbor and midway or just the same model ?

What a nice tour and demo of the BC 610.

Would love to find one of these. Love the old transmitters and boatanchors.

Thanks for a great Video.

I am most impressed with that early iron!

Nice job. Your documentation above is useful, as well. I had a BC-610D in the 1960s, which had been stored fpr a decade in a chicken coop. I added the same model Johnson external VFO. I used the matching desktop audio preamp / control unit.. I also kept the plate voltage at 2500 in AM as well as CW. It did well for several years on 75 meters AM.

i want one of these to sit beside my hammurland sp-600

Super job of fixing up the old gal. I just bought one and will be fixing it up over the next while.Mine is a model H so a little different .Will have to listen for you on the air sometime and pick your brain on some of the finer points of these rigs.

Nice unit! What a great work you did! Put some more videos of yourself in the air waves. Let us listen to your voice. Congratulations.

CW is clean , but RFI can be problematic with the open wire feed-throughs on the side. I went through this. I removed the ceramic feed-throughs, did not add any holes, covered the holes with copper sheet with a hole drilled for an SO-239 chassis mount bulkhead, anchored the copper sheet with existing screws in the chassis. This made a huge difference and solved 90% of my RFI issues. In addition, each line has 1-2 ferrites added (to relay, tuner, LPF etc). Easily converted back.

Excellent, very informative video for anyone who has a BC-610 or HT-4. I just happen to have an early HT-4 (will post a video some day soon). Many thanks!

Very nice demo,I use one in modulation d' amplitude qso in FRANCE on 80m ;but it's a BC610 H

Thank - you

Beautiful '610! I've always felt they sound consistantly superior to the T-368s I've encountered; low modulator drive notwithstanding. I wonder if they key cleanly on CW & how much of an RFI problem they represent?

I want one regardless!
