Does anyone know which mode is which on this rig? I have SB-R and SB-N modes, which is Upper/Lower sideband?

Hi, Rwheindl;

The short anwer is that SB-R and SB-N can be USB or LSB. N = normal and R = reverse for the band you're using.

When you select SB-N, the actual sideband you're using depends on which band you are on - ie on 160, 80 and 40 it's LSB, while on 30, 20, 17, 15, 12 and 10 it's USB.

Examples: On 20 metres, SB-N means you are on USB; select SB-R and you're on LSB.

On 40 metres, SB-N means you're on LSB; select SB-R and you're using USB.

Hope this helps.

Good evening, I am having a problem with our club Omni D 546 "B-Series" HF rig. We get absolutely no sound from the speakers what so ever. No sound from trying the headphone jack either. When I say 'no sound', I mean NO SOUND at all--no hissing, no background noise, nothing. The solder connections on the two speakers are good & tight. I have had 2 other more experienced users of this radio come over with their coax & antennas--no difference. Hear nothing on phone or cw modes. A club member took the rig today to check all the Rx parts. We are 99.9% sure we are transmitting as the S-meter on the rig, the ampmeter on the matching power supply and the "ALC" light next to the main tuning knob lights up on voice peaks. We have tried all the dials, knobs & switches just to see if anything helps, it does not. If anyone has any ideas or similar situations, please let me know. Thank you very much. W2RRK
