Re: Hamlib keying

[Thomas Beierlein]

Hi Christoph,

there were some request for that feature from time to time. Iirc the
last time someone told us there was some cwdaemon like program talking
to the rig via hamlib.

But anyway - your work looks promising. What most users will miss is
the ability to abort the message. It would be good to have a
solution for that problem before merging it in.

I did some search in historic versions of TLF (0.9.10, 0.9.38). The
code above is an ancient left over from former times. (Maybe original
author Rein was a BASIC fan - quite a lot of operations were done as
string manipulations). See it as just a weird coded table.

Having the speed settings as a table allows for a nonlinear stepping -
heavily used in 0.9.10, now only seen on both ends. A plain up/dwn 
by +/- 2wpm would loose that ability. 

Maybe we should extend here and allow the user to set its own speed
stepping. Any thoughts on that?

Hi Onno,
 
there is no way to disable selected bands, sorry.

You have three ways to handle the situation:

- Skip them by using the arrow key twice
- Switch the band on the radio - TLF will follow
- enter a frequency from the band to go into input field and press
  enter.

Can you prevent mode switching?

[Onno VK6FLAB]

When I change bands, TLF automatically changes the mode (CW/LSB/USB), even
if I don't want it to do that. Can I decouple the TLF mode from the radio
mode without losing rig control?

Specifically I want to leave TLF in CW mode, but have the radio in SSB
(LSB/USB per band as appropriate).

How do you disable bands?

[Onno Benschop]

My station is only capable of operating on a selected set of bands, I
cannot operate on 160m or 20m. How do I disable these bands, so my arrow
keys switch from 10m to 80m and from 40m to 15m?
