Re: [AMRadio] RCA BTA-1R1 Available in Washington State...
Wonderful site, those tubes glowing. Ceramic tubes just don't have the charisma and solid state, what a laugh. But to hit the plate switch and see the wattmeter go up to 10 KW or more is a real charge. I worked for KOMA in OKC back in the 60s when they had a WE 50 KW water cooled transmitter. Biggest problem was keeping water in the tank. Be sure you know a nice electrician. 220 single or three phase installation is expensive. 73 Jim de W5JO - Original Message - From: "Dino Darling" <[EMAIL PROTECTED]> To: Sent: Wednesday, February 26, 2003 6:26 PM Subject: Re: [AMRadio] RCA BTA-1R1 Available in Washington State... > I posted a request to a "repeater" group for help in tuning up a 440 > repeater.

Re: [AMRadio] RCA BTA-1R1 Available in Washington State...
I posted a request to a "repeater" group for help in tuning up a 440 repeater. I don't have a service monitor. I got a response from the engineer for KFI here in Los Angeles! I took the repeater to the transmitter site (location of the 750' tower in Los Angeles) and proceeded to get a tour of the site! The Harris 50KW was plugging away, but I wanted to see the real transmitter! He even flipped the switch and I got to see it glow (modulator tube)! Since the solid state unit was operating, the tube transmitter was switched in to a dummy load in the next room. All I can say is WOW! I really really really want an old AM transmitter in my garage!

Re: [AMRadio] RCA BTA-1R1 Available in Washington State...
I parted one out a couple of years ago. I don't care much for the way RCA laid out their transmitters, although they used superbly built components. The physical layout doesn't lend itself for conversion to higher frequencies. They just seemed to place the components in the most convenient spot, then run whatever length leads it took to interconnect them. The result is some extremely long leads connecting critical rf components. That is not so important below 2 mc/s, but to convert to higher frequencies, you really need to clean ouh the whole rf compartment and make a fresh start from scratch, using more conventional hf transmitter construction techniques. I thought the RCA was way too big, so I stripped down the cabinet and used a skillsaw to separate the individual panels in the unibody construction. The transmitter had a lot of missing components and had been sitting for over a year under a leaky tornado-damaged roof, so I didn't think the thing was worth trying to restore. Some of the components went to other BTA-1R owners who were lacking critical specialised parts, and the remainder ended up my parts inventory. The mod transformer and tubes were missing, but I got an excellent mod reactor out of the deal, plus a nice ADC replacement plate transformer. Don K4KYV _ Tired of spam?
