The 1953 edition, immediately to my left as I write this, : has "A 100-Watt RF Amplifier for 50 and 144 Mc." on page 405. It runs : push-pull class-C, up to 120 Watts CW or FM, and 100 Watts AM. Gone by the 1955 edition I have. The 1947 ed uses it in 3 2M TX circuits. I have 3 RCA 829B and 6 or 7 slightly sturdier UK mil CV2666 equivalents, plus some CV178A / 5894 bottles I intend to use sometime in something:-) There used to be a *relatively* popular surplus rig that used three of them. I remember they were lined up and as I recall the final had a tuned line output link coupled to the antenna. Don't remember what it was called. That was nigh onto 40 years ago. snip Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com |

I.F. 1st 30 to 40 MCS, 2nd 4.5 MCS.Range 70-100 MCS...antenna was a 3 element beam, could be vert. or horz. pol... Last time i saw one of these Tx in use , (1959) was at Kimpo AFB, Korea. a slow speed code wheel, was keying the tx on/off.thru the PTT mic. jack...call sign was O K ( 75 MCS , Z beacon) 73`s Gene WB7NGI (TSGT USAF Retired, Radio Maintaner) |
