HCP1550 Heterodyne Channel Processor

HCP1550 Heterodyne Channel Processor

The Drake HCP1550 is a high quality, frequency agile channel processor capable of converting any VHF, UHF, or CATV input signal to any standard output channel between 54 through 550 MHz. Input and output frequency, including output frequency offset, are easily set with front panel push wheel switches. A/V ratio and output controls are also provided along with IF loop-through connections to offer exceptional flexibility.

  • Low-cost NTSC channel processor
  • Synthesized input tuning of off-air TV channels 2 through 69, standard CATV channels 2 through 125, and IRC, HRC channels 1 through 125. All set by a front panel push wheel switch.
  • Synthesized RF output on CATV channels 2 through 78 and 95 through 99, set by a front panel push wheel switch.
  • Selectable plus or minus output frequency offsets with front panel push wheel switch
  • IF SAW filter
  • IF loop-through connectors for scrambling encoders or IF stereo processors
  • High output power adjustable to +60 dBmV
  • Available with "T" Channel upconverter option for reception of channels T7 - T14.
  • Made with pride in the U.S.A.
