Chasers: Show us your station
During Covid-19 lockdown I had some spare time, so decided to upgrade my home station with unexpensive Panadapter based on NaP3 software. I wanted to try NaP3 ver.5.0 to run on my existing Linux Mint computer. It runs well in Wine, but there is a problem with Wine – it was impossible (at least to me) to use USB serial ports!! So I had to install NaP3 in a separate Win10 computer, in my case a 10 inch CHUWI Hi10 tablet. Setup was simple: just connect I/Q port of KX3 to LineIN port of external 24-bit USB sound card (AUREONXFIRE8.0) and connect USB serial port to CAT serial port on KX3. But there was a problem – KX3 was already connected to my Linux computer. So I had to find a solution:
My KX3 is controled by rigctld program, connection goes by USB serial cable.
My logger (CQRLOG) and WSJTX are connected to rigctld over TCP/IP connection. So it was obvious that NaP3 should also communicate with KX3 over TCP/IP connection. Unfortunately NaP3 can communicate only with COM ports. To overcome this limitation, I had to write a short perl script which is running in my Linux computer.
Script takes serial communication from NaP3 and converts NaP3 (i.e. KX3) commands into rigctl commands and sends them over TCP connection to rigctld, and viceversa.
Result is quite good – bandwidth span is up to 180 kHz. KX3 can be controlled from NaP3 screen as well as from CQRLOG and WSJTX. Also interesting feature for SOTA chasers is SOTA spots on NaP3 screen. I can just click on screen spot to get tuned to SOTA activator. Not bad
