2685Re: [V4Protocol] V4 18.104.22.168 -- frequency bug with TS-590S
- Jan 2, 2012Thanks Ian I’ll take a look. Of course the control setup is for not intended to use memory frequencies since sets of the frequency (e.g. from the mini log) are always done using VFO A.Rick KN6KB
You may recall some time ago I suggested you use the "IF" CAT command
instead of the "FA" command to read the VFO frequency.
Well, with the TS-590S I have just stumbled across a situation where
"FA" definitely gives the wrong answer on the V4 frequency display. This
arises when you select a memory on the radio. The display frequency on
the radio changes to the stored frequency, *but "FA" does not change*.
For example, if the VFO was originally at 14.073, then you select 28.073
from a memory, the V4 frequency display remains at 14.073.
This is a bug. To fix it, you need to get the frequency with the "IF"
command instead of "FA". The "IF" command gives you the *displayed*
frequency, which is not necessarily the same as the VFO frequency. I had
to read the "PC Control Command Reference Guide" very carefully to
appreciate the difference.
Now I understand why Simon HB9DRV uses "IF" not "FA" in HRD.
I suspect the same bug will apply to other Kenwood radios as well.
