    • Hello everyone I want to ask if anyone has checked the sensitivity of this transceiver with different IF filters? I checked in CW mode with a 2.3kHz 50mkV filter from the generator, the S-meter shows S=9, and when the 0.5kHz filter is turned on, the same signal is determined by the S-meter as S=6. Is it a malfunction? Or is it so on all transceivers? Sensitivity drops on a narrow band of IF.

    My rig had virtually nil audio output on the 500hz filter 6khz and 2.3khz were fine--cured by resoldering the connections between the filter pcb and the main pcb(both sides where the projections from the filter pcb come thru on the main pcb.
