Hi all, with these 3 bits we can have 8 combinations, actually 7 usable, one is by default (let's say 000) for current messages types (standard of free). I would propose to use 1 combination (001) for DXpedition mode: - 001 when CQ or QRZ in DXpedition mode. This will instruct callers to spread i

Thanks, everyone for the discussion. The biggest takeaway for me is that I shouldn't use the wide graph to determine the quality of the signal, which helps. I do have a waterfall display on my IC-7300, but it has nowhere near the resolution of the wsjt-x wide graph so it’s not very helpful ei

If you throw attenuation at the signal and the issue goes away, the cause is most likely on the receive side. It also helps to have a panadapter available (something that isn't tied into the AF chain). The waterfall itself should not be used to determine signal quality. 73, Jim S. N2ADV

If you want to see what your signal looks like use hamspots.net to see who is receiving your signal.  This will indicate if they are using JTAlert.You can then search for their callsign on hamspots.net to see if they are transmitting...which would mean they are sitting at their rig. Then use JTA

Thanks, Bill (and Gary in the previous reply)! I’m pretty sure my receive is fine - IC-7300 into my mac using USB connection, AGC off, notch filter off, noise blanker off, noise reduction off, IP+ off, and RF Gain/USB AF Output level adjusted to 30 db with no signals present. There is no adjus

Thanks for the insight, Bill. Is there a writeup of the protocol anywhere for deeper understanding? One idea I had after playing around with PSK & FSQ these past few days is to leverage an extra bit to allow for a QSO centered around freeform messaging on HF. Specifically, one of those bits to be
