OV2BU-1000BU-1000 Data Transceiver Board

BU-1000 INSTALLATION The BU-1000 has a 5 pin connector for hookup to the MRU(meter reading unit) modem and a BNC connector for connection to a half wave dipole. The Pin-out of the 5 pin connector is as follows. 1)PTT(push to talk) 2)12V(regulated 12 volt input) 3)mod in(modulation input) 4)RXA(receiver audio output) 5)GND(ground) THEORY OF OPERATION The BU-1000 is a low power data transceiver. RECEIVER SECTION The receiver is a double conversion superhetrodyne design. When in the receive mode, signal is allowed to pass to Q1 RF AMP where it is amplified and sent to U1 for the first mix. X2 is a 3rd overtone crystal which is tripled by Q2 to produce the first mix frequency. The first mixer is located in U1 and produces a 10.7MHZ first IF. X1 produces the 2nd mix frequency of 10.245MHZ. It is mixed in U1 to produce a 455KHZ 2nd IF frequency. Receiver audio is then detected in U1 to produce RXA out. TRANSMIT SECTION Modulation is applied to D3 varactor and is used to shift the frequency of X201 to produce FM modulation. X201 is a 3rd overtone crystal. Its frequency is tripled by Q241 to give the apropriate output frequency. It is then amplified by Q242 predriver and Q243 final. It is passed through D440/441 switching when in transmit mode and from there applied to the antenna.
