BC-250L conversion project in today Radio World

[John K5PRO]

Article in todays Radio World (Nov 9) by Jerry Arnold, K9AF, about conversion of his BC-250L to 160, plus building of his transmitter shack to house it. Nice work, good photos and tips. I could not find it online, but its on page 22-24 of the paper version.

Also, John Bissett's Workbench column in the same issue has a story I sent in recently, see  "Rodents and AC Don't Mix".

Hey John:  Is this article in radio world about the rca bta-250L transmitter? I sure hope it is. I am in process at the present time of converting my rca 250L to 160 mtrs. Well actually at present I am trying to get it on the orginal 1400khz that the radio station had it on first. Waiting on a tube 8008,  it should be hr this week. And then I will start looking for information on how to convert it to 160 mtrs, So I am hoping this article is abt the RCA BTA-250L like mine. Please let me know. Thanks Matthew KR4WI

No it was about the Gates BC-250L, which used a parallel pair of 810s for RF.

Sorry!

Is the RCA BTA-250L the narrow tall box with 813s in it or another?

Hello John:  No the bta-250L has a pair of 810s also, and modulated by 828s. A 828 buffer, and 807 oscillator. It is 40" wide,80"tall, 21"depth and weighs in at 1360 lbs net. Made in 1947 acording to manual, I have been working on it for abt two months, I thought sure I hit the jackpot when I seen your post, and got a little, well a whole lot excited. hi Well thanks alot for the information.
