From the Ten-Tec Reflector - October 1, 2007
The current list with contributions from: VE7BGP, WA3FIY, N4NT, NN8B and NS1W. Thanks too all.
Model | S/N | RX Mixer | Front Panel | Contributor |
---|---|---|---|---|
525 | 00721 | 1496 | Argosy | VE7BGP |
525 | 00748 | 1496 | Argosy | NS1W |
525 | 00895 | 4 diode mixer MBD-101 | Argosy | NN8B |
525 | ????? | 4 diode mixer | Argosy | KW7CD |
525 | 01096 | 4 diode mixer (TO-92 diodes not marked: probably MBD101) | WA3FIY | |
525 | 01188 | 4 diode mixer MBD101 | WA3FIY | |
525D | 01611 | diode quad ND487C1 | Argosy | N7WIM |
525D | 01810 | diode quad ND487C1 | Argosy II | WA3FIY |
525D | 01892 | diode quad 87clk32 | Argosy II | N4NT |
525D | 02497 | diode quad ND487C1 | Argosy II | N7WIM |
525D | 02591 | diode quad ND487C1 | Argosy II | WA3FIY |
So the conclusions are:
The serial number 0823 comes from the change in noise blanker design hypothesized to match the mixer type: Model 223 for 0823 or less; Model 223A for 0824 or more.
