Hi Jim, I don't think this is a serial port issue any more. Why do I think that? Because you said that fldigi does read the frequency, the mode, and the filter width. You also said that wsjtx, via hamlib, also controls the rig (ptt as well) via the same hardware setup. I assume you can change these values (freq, etc.) in fldigi and the k2 changes in a commensurate fashion.
Ok, what's next? Hmmm... I assume you are using the K2.xml file from https://sourceforge.net/projects/fldigi/files/xmls/elecraft/. I wonder if the ptt cat command is not correct in that file. But you said fldigi on windows works and I assume you are using the same rigcat file (k2.xml)?? Is that correct, are you using the same rigcat file I reference? I had a quick look in that file (from fldigi rigs file download section on sourceforge) and noticed a small error. The following is incorrect from the file on the site: <COMMAND> <SYMBOL>INIT</SYMBOL> <SIZE>*3*</SIZE> <STRING>K22;</STRING> </COMMAND> The highlighted 3 should be a 4. The <size> is supposed to include the semicolon in the <string> tag. The effect of this error is that the K2 will likely not be placed in extended command mode. The TX; and RX; commands don't have extended modes. But, perhaps other commands that need extended mode might affect the TX and RX cat commands. Not sure. But, certainly worth changing the k2.xml file in ~/.fldigi/rigs to correct the error and then give it a try again. Also, I noticed in Elecraft's documentation that the K2 must be in either SSB or RTTY modes in order for TX; and RX; cat commands to function. The k2 won't respond when in CW to TX; and RX;. http://www.elecraft.com/manual/KIO2%20Pgmrs%20Ref%20rev%20E.pdf. I am not sure why Hamlib isn't working with Fldigi. I haven't had much luck with Hamlib and Fldigi and usually opted for rigcat. Mostly because it worked the first time (so I could start to operate and have fun) and I was able to tinker with the cat commands to add more customized filter widths and names than those provided in the kx3.xml rigcat file I use. regards, Brian VE3IBW On Tue, Nov 21, 2017 at 9:54 PM, Elmore's <[email protected]> wrote: > Please carefully read everything that follows to avoid repetition of the > steps followed.
