Dunno if your 9k does dual watch, where you can copy on two different freqs at the same time. Icom pioneered this methodology with the 781 as I recall, see here;
"The IC-781 was originally designed under a defence contract; the Dual Watch feature is quite well suited to guard-frequency monitoring in the same frequency range, or the monitoring of both frequencies in a half-duplex (split) situation. These scenarios often arise in some military/government HF operations. The utility of Dual Watch in the amateur radio service could well be incidental to the original design intent."
https://www.ab4oj.com/icom/dw.html

In my case the 775 and 756 P2 do dualwatch and I've found that even though there's a bandpass switch when tuning from 12464 to 8345, when the lower tuned freq is the primary it seems to work out well enough. To get the full sensitivity of the rig in dual watch mode on both freqs, those freqs have to fall within the same bandpass filter. The 8345 falls outside the 40m HAM band preslector, wich extends from 6MHz to 8MHz, the next extends from 8 to 12mHz, sadly cutting off 12464, but it still works out fine.

I can copy traffic on both easily enough with dualwatch. The sdrs available here do not cover the range one can employ with dual watch, but they do fine in the bandwidths they do provide for. I suppose most preselection filters in HAM rigs are of the sub-octave pie network type, wich offers a more or less symmetrical bandpass.

Thanks Josh

I donít remember seeing anything about dual watch in the manual, Iíll check.

Josh, were those on 8345 or 12464?  I was on 8345 and missed them.

Sorry, was sneaking in on 12464 long after I expected traffic to move to a lower qrg. There may be some traffic on 8345 as someone keeps sending K at random times, I suppose they have traffic of higher priority or other that they want hq to copy.

Thatís cool, was just curious.

Excuse my ignorance, but are we receiving the message from the ship or the HQ?

Disregard my question, you answered it earlier in this thread.

I've yet to catch RCV, RIW, RIT, or RMP, the hq stas that use the other side of the duplex channel, perhaps due to lack of decent antennae on my part in addition to the fact those stations are several thousand km further away from here than the ships we can hear routinely. Have to park a rx on them and wait for something to happen.

Very noice, lotsa traffic lately. I caught RIT being called by RMGB today on 8345 but was too lazy to get out of bed to see what time it actually was. Then RMGB was back around 1pm local with decent sigs.
