To the N1MM powers that be, While I have developed a procedure that allows N1MM "key closures" to be transferred to PowerSDR via vCOM's DTR/RTS signals, it is not an efficient way to go. After all N1MM must generate accurate toggles of DTR, then PowerSDR must interpret them and generate accurate audio waveforms to "key" the rig. The process in N1MM takes about 40% of a 3Ghz cpu and PowerSDR takes about 20% of a 3Ghz CPU.
With 60% CPU utilization, getting N1MM and PowerSDR to cooperate smoothly requires affinity and base priority juggling which is likely beyond the capability of an average ham. Particularly true given the likely presence of other supporting apps running in the same machine. Fortunately there is another alternative which works for both Kenwood and FlexRadio rigs. This is to send ASCII characters via the Kenwood "KY" command over the CAT interface. This requires almost no cycles on N1MM's part, puts the timing burden on Kenwood and PowerSDR, and eliminates affinity and base priority juggling. Clearly such a solution would be advantageous to both Kenwood and PowerSDR users. Such a solution is also in line with technology trends. It would also reduce the ongoing string of CW questions flowing to the N1MM reflector. As developing the code for this is non trivial, I would normally be reticent to recommend this change. However, Dave Bernstien, AA6YQ, has already generated this algorithm for his WW app. Thus there -may- be a possibility of acquiring the appropriate algorithm/code. I hope we can find a way to make this change an easy enhancement to N1MM's fine Logger, Thanks for listening, Vy 73's Rob AB7CF Cc: DXLabs, FlexRadio Ps. I haven't talked with Dave about this at all...
