Fldigi unable to change frequency of wfview with v2.03

Bugs
1

Brief summary of problem (put in title as well):
Fldigi has the ability to control the rig’s frequency through the RigCtld interface in wfview. This is an important function because you can move a CW or digital signal to the exact middle of the radio’s audio passband.

This works in wfview 2.01 but not in 2.03. Wfview can change the frequency in Fldigi with both 2.01 and 2.03, but you cannot change frequency from Fldigi with wfview 2.03. When you try to change the frequency in Fldigi either by clicking on the displayed digits or the QSY button to move signals to the middle of the audio passband, the frequency does not change.

This is with Fldigi 4.2.06 compiled from source. I have not changed the version of Fldigi during this testing.

Please let me know if you need more details or more info or screenshots from Fldigi and wfview settings.

Radio Model: Icom IC-7610
Connectivity (USB/Ethernet/Wifi/Other): USB

Tried to google it (Y/N/NA): NA

What I did:
Tried to change frequency in Fldigi.

Expected behavior:
Frequency should have changed.

Observed behavior:
Frequency did not change.

I haven’t tried fldigi with wfview v2+ other than the most basic of testing, so it is quite possible that I missed something. I will test and let you know.

Noticed that the branch “virtual-series-test” had been merged into master. I downloaded and installed this new master and fldigi can control the frequency of wfview again.

Just downloaded and installed 2.05 on Raspberry Pi 5 running Bookworm with all the latest updates. This issue has reoccurred. Fldigi can no longer control the frequency of wfview. Reverted to 2.04 and we do not see the problem.

I have just pushed a fix for this to master. For some reason, fldigi sends frequency as a double-precision floating point number (14070000.00000 for example) which was confusing the new parser. That should now work.

Thanks. I’ll rebuild shortly and let you know if this works better.

Bug fixed! Thank you so much. I use the QSY button in Fldigi all the time to center CW and digital signals in the exact middle of the audio passband. I love all the new features in v2 and I see even more in 2.05. Thank you and 73!

And version 2.x is wonderful with my IC-7610. I particularly love the features for ease of split and dual-watch operation and improved interaction between main and sub VFOs. Indespensible for chasing CW DX when operating split.
