QST, Mar 1976, p. 135. QST, Aug 1976, p. 163, (Described in as the sixth generation (E series)) QST, Apr 1977, p. 4. 73m Oct 1977, p. 175. MPC-1000C Multipath-Diversity $495.00 The MPC-1000C features multipath correction, in-band diversity (single channel copy during deep selective fades) operation and a phase-continuous AFSK tone keyer. The mark and space channels are continuously tuneable from 1200 to 3100 Hz. The internal RY generator and dual-mode autostart (FSK or mark) are standard, as are rear panel provisions for signal regeneration and speed conversion peripherals. MPC-1000CR Signal Regeneration & Up-Down Speed Conversion $595.00 The MPC-1000CR combines all the features of the MPC-1000C with the TSR-200 speed converter-regenerator. A front panel signal speed switch provides electronic "gear-shifting" between 60, 66, 75 and 100 WPM speeds. All incoming and outgoing signals are regenerated by a CMOS UART and a crystal-controlled dual-clock to less than 0.5% bias distortion, providing an extremely low error-rate on weak and badly distorted signals. MPC-1000R Dual-Uart Regeneration, 200 Character Fifo Memory & Word Correction $820.00 The MPC-1000R combines the features of the MPC-1000CR with the TSR-500 speed converter-regenerator and offers 200 characters of FIFO memory, a dual-UART regenerator that also provides local copy during all preload-recirculate functions, a word correction circuit that permits an incorrect word to be erased from memory by depressing the local keyboard's blank key, variable character rate and automatic blank/ltrs diddle. Character overrun during down-speed conversion is prevented by an automatic character rate over-ride and tee dee inhibit circuit. Three preset AFSK tone/shift combinations are selectable from the front panel. The MPC-1000R (80 characters of memory), MPC-1000CA (tri-tone AFSK), MPC-1000CRA (tri-tone regenerator) and MPC-1000CS (crypto-scrambler) are also available.
