    Programming Additional Features

  • After the frequencies have been programmed there are some additional features to be added in the programming

  • At Memory location 640 the Transmit Time Limter is set

  • Some early models of the KP150 (KG109) were fitted with the uPD7530BGF KM753C-111 CPU if this is the case '00' MUST be programmed in location 650.

  • From address 670 to 7F8 the CTCSS tones are set for each of the 99 channels

  • The information below covers both the original 09QCTA CTCSS board and also the Sigtec C1124 CTCSS board.

    The CTCSS data is entered into the eprom as follows
  • IMPORTANT note a code is required even for NO CTCSS with a CTCSS Board fitted

  • The NO CTCSS code for a 090QCTA (original CTCSS Board) or C1124 (Sigtec) differs, check which board you have

  • To enable the Tx Timeout Timer on the C1124 CTCSS Board, 1 needs to be added to both the CTCSS Rx & Tx Data-1 codes (see example in table below)

  • J1 - Increases decoder bandwidth for non-crystal controlled repeater panels
  • J2 - Tone phase change A=180 deg B=120 deg
  • J3 - Link with diode enables monitor button
  • J4 - Linked disables Tx lockout
  • J5 - Leave unlinked

Alignment of Radio

  • Supply Voltage 9.6v
  • Adjust TX and RX VCO trimmers for approx 3v (Range 1-5v)
  • Test VCO voltage at Test Point
  • Calibrate frequency with VCO frequency adjust trimmer
  • Adjust maximum power and then align High Pwr Set / Low Pwr Set if radio has switchable power levels
  • Tune front end coils x 4 for maximum receiver sensitivity
  • Squelch is preset with radios with no squelch pot

  • PLEASE NOTE: I am not able to supply blank flexi track mounted 27c64 eproms but can program them. I do not have any other parts for the Key KP Radio, only answer questions about KEY KP series radios ! (I'm always hunting for Key bits myself though)

  • Hopefully readers of this article will be familar with how to actually program a 27c64 eprom.
  • Key used to manufacture a special programming adaptor for the flexi track mounted 27c64 eprom which converts it to the normal 28 pin DIL socket to blow its data.
  • Before you ask I only have one of these adaptors and its not for sale !

  • Please contact epromsatsuperiorsignals.co.uk for programmed devices @ 5.90 UK pounds or 7.5 Euros including 90p postage (Please note you need to supply the blank 27c64
  • )
