Neil, As I said in a earlier email, RCA was sued successfully by GE because it was so obvious that RCA had copied the GE Master II design. The RCA looked almost exactly like the GE, what was RCA thinking! RCA would never recover and shortly after closed the radio division.

I believe the 1000 was the better known as the ML1000 ML for the RCA plant in Meadowlands. The 1000 or ML1000 was a larger (higher power version) of the Series 700 radios. With this discussion, I finally went out to my garage ... and went looking ... and found the following - all RCA: Three ML1000 manuals on 50 and 450 MHz bands. A Tac 200 (VEETAC) Fixed Stations manual (SM-8025626-1) 150 MHz (Signed and dated by the late Walt Braunstein, 9/80) The RF package (Transmitter/Receiver) at quick glance looks like a Mastr II ... careful study inside parts look like an early Motorola Syntor or 100 watt Mitrek. Uses a Temperature-Compensated Crystal Oscillator - TCXO that in the picture looks very like a take-off of a GE Integrated Circuit Oscillator Module - ICOM. The CTCSS 'Quiet Channel' module is immediately behind the front panel just like the Mastr II. The antenna relay is a take-off from a Micor. The receiver front end helical resonators are soldered to the circuit board. The control head looks like a cross between Micor and Mastr II control heads. Internally looks like a Mitrek control head. ----- I trust there a few folks who fondly remember the earlier RCA gear. For you, I found the following: An October 1978 Price Schedule for Replacement Parts and Accessories for RCA Mobile Communications Equipment. (2 copies) Advertising poop sheet for VEETAC control head stacking kits. Advertising poop sheet for the VEETAC High Band and UHF radios. Some TAC300 and TACTEC service info and a photocopied CMU-10A manual. Original factory supplied manuals: Super Carfone 450-470 mobile station. Remember the instant heating tubes? Carfone 450 CSU-15C ... base station used a 5894 in the final. Carfone CMV-4 ... the receiver crystal formula: Channel Freq - 0.915 Crystal Freq = ---------------------- = 11.62 - 13.3 Mc 13 The first LO crystal was used twice ... The receiver was 152-174 MHz ... The first IF was 12/.54 - 14.23 Mc (walking IF) The second IF was 915 Kc Used a relay to change channels - the relay contacts switched the crystals ... not crystal oscillators. Carfone Portlable Transmitter-Receiver CTR-1A weighed 44 Lbs. Fleetfone CMV-2EL, CMV-3EL, low band, used 1 or 2 807's in the final depending on the power output. I have two copies: one is stamped Mann C & E on the front cover. Remember the RCA 'E Line'? E = Efficiency CMUE-15A2T with a Joe Olivera signature on the front. Super Basefone 25 - 54 MHz, 100 watt written on the front is Baldwin Hills (A CHP radio site in the Los Angeles area) Remember the FCC required 452-C tags - Transmitter Identification Tags to be stuck to every FCC licensed transmitter? I have a few of the original RCA labeled 452-C tags. Another place in my garage ... you remember the Motorola Service Station peel-off-the-back stickers you stuck on your your service truck? I have one that says RCA. You thought you collect stuff?
