All,

I am trying to setup quisk to communicate via ttyS0 to an external device (arduino) to control my amplifiers LPF's.? I have my user name in the dial out already.? In the remote menu I have set up CAT to /dev/ttyS0 which is a real serial port and have it connected to the arduino but I cannot get it to do anything.? The arduino is programed with ok1cdj code for band decoding and I have tested it with my picastar which emulates a TS2000 for CAT and it works so I know the arduino is working.? Since quisk uses flex cat commands I figured this would work.? When I loaded the sketch to the arduino I also changed the baud rate to 9600 following the instruction in quisk.? Serial port shows being set to 9600 also.

I really would appreciate some help with this.? I sure hope this is possible and I am likely missing something here hopefully just in the way I have the serial port setup in quisk.?


Thank you

Quisk reads Hamlib commands from the serial port. It does not send Hamlib commands. If you want to send Hamlib commands you need to program the required commands into your custom hardware file.

Jim,

I should clarify I have the arduino connected to ttys0 physical comport of the computer and just need to read the current frequency in quisk.?

I am a little confused about how this works. ?I only need to read the frequency from quisk on the serial port as if my arduino was connected to the CAT serial on a physical radio. ?Is this not possible?

Now I understand. The serial CAT was designed to communicate with other programs such as?N1MM+ or WSJT-X. So it creates a virtual serial port with one end connected to Quisk and the other end to the program. This won't work with a real serial port on Linux. Linux users generally use Hamlib rig 2 for CAT. This uses a network connection. Or they use the Fldigi XML protocol.

It should be fairly easy to connect the current logic to a real serial port. I will add the feature to the next release.

Thanks Jim,

Somewhat unrelated. I do have hamlib rig 2 setup in cqrlog and it is working fine. I also gave JS8call a try for the first time but couldn’t get hamlib to work there so used the serial port from quisk and it worked. ? As of last night I upgraded to the latest hamlib and they’re both working now. ?

The serial port interface is going to run the lpf on two amplifiers. ?Using the ldmos big amp at only 35 to 50 watts out is terribly inefficient! ?Going build another 100 watt amp using Jim Veatch boards with an enormous heatsink just for digital modes.
