I picked a nice looking Supreme brand six meter SSB/AM tranceiver at a local hamfest. I've never heard of this brand and can't find any info on it. It uses a 6146 in the final, almost if not all tube and has good quality components with point to point wiring. The thing is about the size of an old Swan 350 and looks internally almost homebuilt but I've been told that in the mid 60's era(I'm guessing about the era), many small xcvr makers took a few shortcuts for finacial reasons. Any help would be appreciated, especially a schematic. Thanks a lot. John - K7RLD That name doesn't bring up any memories. There were some obscure companies making VHF SSB transmitters back in the sixties, but I can't think of any SSB transceivers from obscure manufacturers. Maybe it was something that never made it to North America, there was Japanese equipment that never made it over here, and of course there was some stuff manufactured in the UK. If it looks homemade, that likely reflects a very small company, which this surely had to be from. Maybe it's a prototype, that never made it into production (or advertising). Maybe it's just someone's very fancy home made rig. Maybe it dates from later? Once semiconductors got good enough, there was some neat stuff coming from Europe. Not that it was imported much, but we were seeing ads for it. You might want to specify what tubes it used, or even if it was all tubes. There wouldn't happen to be a plate on it that specifies a date? A plate that says where it was manufactured? Is it a filter (and what frequency?) or phasing rig? Is it VFO controlled, or crystal controlled? Can you see any crystals in there besides the carrier oscillator, to give an idea of the first IF? (Considering the date, if it's not crystal controlled it's got to be a double conversion unit; most VHF SSB rigs of the era would be in effect a receive and transmit crystal controlled converter along with a low power transceiver, often operating in the 14MHz range. Maybe none of these details will help to track the manufacturer, but it is definitely a curiousity that others would like to know about. Michael VE2BVW |

Hi, Just my two pennyworth but if it's 1960s-era gear it's unlikely to be UK made as we didn't have Six in those days, that band was occupied by black & white TV at that time. We didn't get Six back until the mid-80s. 73, -- Roger Basford (G3VKM) |
