I tried to control my "FUNcube Dongle Pro" SDR with Hamlib. At first it
worked fine, but when I tried to correct the frequency divergence with
the vfo_comp parameter, I found a bug in the software.
Example:
$ ./rigctl -m 2513 -C vfo_comp=0.01
Rig command: F 100000000
Rig command: f
Frequency: 102010000
The correction must toke place when setting the frequency and when it
is read back. But one time the correction must work in on direction,
the other time quite opposite.
I found the code in the file rig.c and could see, that both times the
same calculation is used.
The simplest way to correct this is to go to the “rig_get_freq(“
subroutine and change it in the line 1188 from “+=” to “-=” , even that
is mathematically not correct.
Result:
$ ./rigctl -m 2513 -C vfo_comp=0.01
Rig command: F 100000000
Rig command: f
Frequency: 99990000
$ ./rigctl -m 2513 -C vfo_comp=0.000022
Rig command: F 100000000
Rig command: f
Frequency: 99999999
You can see, that the result is quite good for small divergences of
some ppm, but there is still an error for bigger divergences. So I
changed the line 1188 to the form I hope it is the mathematically
correct one:
*freq = (freq_t)(*freq/(1.0+(double)rig->state.vfo_comp));
Result:
$ ./rigctl -m 2513 -C vfo_comp=0.01
Rig command: F 100000000
Rig command: f
Frequency: 100000000
$ ./rigctl -m 2513 -C vfo_comp=0.000022
Rig command: F 100000000
Rig command: f
Frequency: 100000000
Now the result looks good for small and for bigger divergences.

Workaround for fldigi
fldigi treats zero frequency as error and disables hamlib.
So if the device rports zero frequency return 1 Hz instead,
so the user can switch to the favored frequency
The TS-711 and TS-811 use an IF10 board just like the TS-140/TS-680/TS-590
and thus share a lot of the same commands with it.
Tested:
* TS-711A
* TS-811E
Hi,
I had trouble with CTS serial port squelch (on microHAM USB Interface III).
It seems there is a bug in the hamlib code and I think the similar thing
should be done as has been done for the pttport, i.e. if the dcdport is
the same as the rigport, do not reopen it. Otherwise the serial port will
be reset to its default and it will key the radio PTT forever (because
the RTS line is reset on the port reopen). Patch attached

Hi,
on 64 bit distros with /usr/lib64 (e.g Fedora) the hardcoded libdir in
pcconfig is wrong. The attached patch tries to fix it. It also applies
to 3.1

Expand variable substituion for hamlib.pc
Further testing showed that 'exec_prefix' and 'includedir' would benefit from
variable substitution by the configure script.

This flag can be used by back ends that need to take special action
while the rig is transmitting e.g. the FT-747GX and similar that do
not process CAT commands while transmitting.
The flag is also used as a default answer to rig_get_ptt if nothing
better is available.
Deal with inaccurate CAT query for Rx/Tx on the Yaesu FT-847
This rig doesn't set the Rx/Tx status flag when PTT is asserted via
the PTT pin on the rear PACKET socket so we need to override which we
can do if we known we have asserted PTT via rig_set_ptt().
Adjust style and fix set PTT defects
Fix a warning from a declaration of a deleted function definition
Various SDR consoles are supported by the TS-2000 back end, ensure
that commands unsupported are not sent to them. Added a flag that
shows back end is talking to an emulation like SmartSDR or PowerSDR.
Found that when nothing was installed that check-tcl failed with a
failure of tclsh not being able to load the shared library. Thanks to
assistance from comp.lang.tcl, copying pkgIndex.tcl to $(builddir)/.libs
prior to loading the test script allows the script to load the shared
library immediately after 'make' and before 'make install'.
Prefixed various TCL section target commands with either $(AM_V_GEN) or
$(AM_V_at) to conditionally silence the output of 'make'.
Remove execute bits for all test scripts and install them into
doc/examples.
Make sure check-py and check-tcl targets work.
Set a conditional for Python3 or Python2 and install/test the correct
script file.
Use Makefile variables instead of configure substitutions wherever
possible.
Generate tcltest.tcl at make time to insert installation library path
into the script so that tests pass.
