The binary data in 56KEC05A.BIN must be burned into a 27C256 EPROM with an access speed not slower than 150 ns.
NOTE: Be sure to turn dip switch #3 ON to enable ECC mode.
The following table list the modem IF frequencies available in the EPROM.
Memory TX Freq RX Freq RC Code Tuneup Freq ______ _______ _______ _______ ___________ 0 29.050 29.050 20 29.050 1 29.150 29.150 20 29.150 2 28.400 29.850 20 29.850 3 29.850 28.400 20 28.400 4 28.550 29.550 20 29.550 5 29.550 28.550 20 28.550 6 29.250 29.250 20 29.250 7 29.350 29.350 20 29.350Notes:
Memory 1 is for the Lanier Mtn bit repeater on 440.150/445.150 using a 440 mhz transverter with 2 LOs. The LOs are switched between tx and rx for the 5 mhz split.
The 440 mhz transverter crystals are 104.000 mhz for receive and 102.750 mhz for transmit. These are 5th overtone series resonate crystals.
Memory 2 is for the Sweat Mtn. bit repeater on 222.400/223.850 using a 222 mhz transverter.
