Circuit diagram 75 Meter QRP SSB Transceiver
The 75 Meter QRP SSB Transceiver Theory of Operation 6-30-03 In general, the transceiver switches the 4-element 1500 ohm xtal BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T operation. Since no IF amplifier is used in the design, 20 dB of additional receiver gain is […]
