Ashhar, I'm not familiar with "Net Rig Conttrol"? ? Is this related?to "rigcat" which is one of the options in FLDGI?? ?

• "rigcat" came from the authors of "fldigi"?
• "net rig control" came from "hamlib" which came from a different group
• it's more correct name is "hamlib net rigctl" based on the "rigctl" program provided by the hamlib-utils package you can install on the Pi
• both "rigcat" and "hamlib" support a programming interface that supports many different kinds of radios underneath
• "wsjt-x" chose to support "hamlib"?
• "wsjt-x" is massively popular
• because of this, most people want/need "hamlib" to work
• SDRs don't have actual serial ports
• the easiest way for a SDR to support "hamlib" is via a local network TCP/IP connection
• the SDR's code can respond to the 127.0.0.1 "localhost" address at a specific port
• the SDR's code then reads commands and writes responses to/from the network
• the applications (e.g. "wsjt-x") include the "hamlib" library in their run time code
• the hamlib support gets configured by user input to either use net rigctl or an actual radio serial port
• based on this choice the hamlib code calls the right functions to get the desired behavior
• "fldigi" supports either rigcat or hamlib so hamlib appears to be the more universal choice

This is a screen shot of wsjt-x selecting hamlib net rigctl:




You can see the "localhost" TCP/IP address (127.0.0.1) followed by ":" then by the port number used by sbitx to support rigctl (4532).

This is a screen shot of fldigi's rig control choices in its config dialog with hamlib selected:


?
Note on the left that you can use hamlib or rigcat or other approaches.

Note the sbitx hamlib.c file is lifted from the 'gqrx' SDR application's source code and isn't a full implementation of hamlib net rigctl.

Sbitx itself does not implement rigcat.? I presume you can set up flrig to be a "rig control gateway" that can use hamlib to talk to sbitx, but I presume the limited implementation of hamlib on sbitx means this probably doesn't work very well.? I did try the "grig" linux program and found it wasn't very useful because sbitx's hamlib support is limited to just the things wsjt-x needs to operate and not much more.

The sbitx community should find a better "radio side" implementation of hamlib net rigctl to lift.? I haven't looked at other open source projects to figure out if there is a better one to lift, but pretty much every SDR radio app that wants to work with wsjt-x needs to have one.? I have used "quisk" with hermes lite 2, maybe it has better support, I don't know.? Also looking at linhpsdr and/or pihspdr may provide a better implementation.

At a minimum just be able to set the frequency and possibly go into transmit mode.

4) Use the 'rigctl' command to send hamlib commands to the sbitx application

5) The following set my sbitx's frequency to 7070 kHz

$ rigctl -m 2 -r 127.0.0.1:4532 F 7070000

Interpretation:
> -m 2 means mode 2 which is hamlib net rigctl
> -r 127.0.0.1:4532 connects to sbitx's hamlib implementation (see earlier post)
> F is the frequency command
> 70700000 is frequency in Hertz

6) Do 'man rigctl' then move forward till you see 'rigctl Commands' to get a list of the commands that should work (but most don't).

7) Cross check this with $HOME/sbitx/hamlib.c to see what is actually possible (hint: not a lot)



So you can see the 'T 1' command puts the radio into transmit and 'T 0' takes it out.

As we used to say in the early days of open source, UTSL (Use the Source, Luke!).

?if there is a way to access the sound card so much the better but external sound cards can be used. ?

Hi, Thanks.? ?Maybe I'm not explaining myself well.

?

Extremely popular and well known and important applications widely used in the ham radio community?such as N3FJP and WINLINK's entire system, do not appear to support hamlib or other systems.? ? Making control?via telnet will not work with these applications.? ? ? these aps are WINDOWS.?

?

The easiest way to make all of these applications?work, is to have an emulator that appears to be some radio.? ? That emulator can then call a telnet command, or interface via ham lib or any way it chooses.? ?But I doubt you are going to get N3FJP or the limited WINLINK staff to jump to your tune.??

?

I hope that epxlains?the issues better?

Hi JJ,

There is no tx_compression implemented in Farhan's (there are no programmers, just one programmer) sBitx code.

- Rafael

Compression IS a value that is available via telnet in v3.x so I assumed it was still in v3.x code. The compression setting is available in v2.0 as seen here.

Harald,

1.The compression didn't really work, so I took it out. Once we have a decent algo, we will put it back in.

2. The macros are text files stored in web directory /home/pi/sbitx/web. The format is same as N1MM.

3. I am not sure why the disconnection is happening. Something is timing out in hamlib. It will take me a few days to get back to programming again.

So the functionality was taken out, but apparently the telnet code wasn't updated to reflect this.

sBITX Toolbox version 1.4 is now available.

Hi JJ, after using the update menu item, mine is now set to v1.3, and says it is the latest version. Bug?

Enjoying your work mate ;-)?

JJ,

Just a reminder, you Can read the tuning knobs too from your suite to choose through settings, et al.

I encourage you to update the app and let me know how it goes.
