Thanks to Jeff Easterly, for sending in detailed information about the Buddy Base line of transmitter / receivers. Sounds like a rig I must add to the collection :-)



Hello, Dave!  :-)                                                        Tuesday, November 27th 2001
        Sure enjoyed reading the write-up on the Buddy base.... I currently own 4 Buddy TX-11 transmitters, & a friend KK6OY in Running Springs, CA has a complete TX-11/RC-11 base set-up, w/ matching speaker, sitting over at his Dad's place, in daily use...the early TX-11/RC-11's were built w/ gold anodized faceplates, w/ the later 12 & 23-channel versions being black...the TX-11 schematic I have reads a design date of March, 1962... I've been running a TX-11 transmitter now w/ a Demco modulator, using a Browning R2700 or R2700A receiver, as my front-line assault weapon since I stumbled upon the combination over 15 yrs. ago... in 32 yrs. of doin' this nonsense, I just can't find anything that'll out-talk this set-up... it's easy to get spoiled runnin' older tube-type equipment, as it brushes aside the high noise levels & bleedover commonly found in transistor & PLL receivers,& just simply "gets w/ it"...
        The TX-11/RC-11series was only 6-channels on transmit, & then the early TX-11B's had a 12-position channel selector, w/ the identical tube compliment...later, an outboard crystal box was available to expand the frequency coverage to the full 23-channels available...then, the TX-11B/RC-11B series was introduced, w/ a full 23-channel crystal bank, mounted inside the transmitter cabinet... I'm fortunate to own 3 TX-11B's, & one of the transition TX-11B  12-channel rigs... you could tell if you were getting a pieced-together radio, or a factory assembled unit w/ all 3 matching pieces, as they serial numbered each piece w/ an identification tag, & all the numbers matched if it had been shipped from the factory as a complete radio... my 12-channel is pieced-together, but 2 of my 23-channel rigs are serialed alike...I found out about Buddy Base radios from a good friend who used them ( Black-face Johnson Channel 23 receive crystal, used for transmitting.... w/ the variable receive cranked-down... ) w/ the Little Brother's Truckers CB club, from the Hemet, CA area... the 23-channel units also had an optional heavy-duty power transformer, that would allow you to replace the 6V6 modulator & the 2E26 final w/ the 6L6-6146A combination, & then install a switchable high-low diode pak that gave you two power output levels... either 7 watts dead-key on low, or 40-45 watts, dead-key, on high... You could reach down inside the cabinet through the ventilation slots to reach the slide switch on the diode pak...I know, I have one, put away, w/ the bigger modulator & final tube...I knew fellas who ran a 23-channel Buddy Base w/ the high-power conversion into stacked 3's, & they were tough to beat... if you ran a 3-wire pre-amp D104, w/ the on-off switch in the base to save the battery, the only guys who could give you trouble were using a General Super MC-11A or MC-12, w/ a Demco modulator, & the "belly-button" in the rear apron socket!... I also have a Buddy 2 meter AM 10-channel transmitter, that looks complete, except for the outboard power supply... it appears to be an AC-DC unit, as it has transistors mounted on the cabinet rear, like so many other AC-DC rigs of that period... wanted to get this out to you, to add to the knowledge of these fine radios...Buddy / Autotronics / Marina Communications were a lot like Johnson....they could build a great transmitter circuit, but their receiver designs just weren't up to the task of dividing signals that were spaced only 10 kcs apart... but, if you lived away from the big city, & didn't have many CB neighbors, they would perform nicely.... hope this gives you a little more to add to the Buddy Base information "pile"... always happy to share my limited knowledge ( but I'm currently running short of practical information...anyone got any they can spare? ) ... 73's & continued success....
