Re: Writing the ICOM EMULATOR for the sBitx
|
Looks?like the sBitx has a telnet socket.? ?I think maybe once in my life I've fiddled with that.? ?I'm running V2, not sure how much is implemented there; maybe I can use putty to check? I might be able to send the commands to sBitx via a socket? I see that W9JES has an upgrade file for remote.c that apparently fixes something in the sBitx related to disconnections. I found a nice description of a bunch of telenet files in a page pointed to by Ashhar:??? but it specifies V3.? ?And I'm working my DE version, which is running V2....? anyone know how much of the telnet was implemented on V2? Thanks! Gordon KX4Z

You could do this far, far better than I!!!? ?Don't hesitate to jump in and put?this on the sBitx!!! However, I will chug along if only for my the curiosity of my soul.... I have now figured out how to control the TX and RX on/off, and set the Mode. Your code did far far more of cours!!! Again, don't hesitate to rip right into this and get 'er done!

Sounds like you're making good progress. Be aware that the ICOM CAT control from hamlib can be tricky to implement.? As you discovered, it is a binary interface, not ASCII text.? It uses binary coded decimal for all numbers and commands. and it requires some very specific protocol to work properly without hanging up either your radio or the calling program.? I wrote an emulator for the IC746 to replace the Yaesu interface on the uBitx.? It fully implements the ICOM CAT interface including setting frequency, mode, split and so on. t should port easily to the Pi.??
I wrote it do that it is easy to add CAT to any homebrew radio.? You just need to write short functions to send the appropriate command to the sBitx software.
