2684V4 126.96.36.199 -- frequency bug with TS-590S
- Jan 2, 2012Rick
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.
