[Wrtc] Hint for Ctrl-S Frequency Problem

[Bernd Och]

Hi,

I am testing the newest 3.0.1-wrtc from today.
I still have the Ctrl-S and Frequency Problem.

Here is the Setup:

Radio-A = FT-1000MP Mark V
Radio-B = FT-1000MP (old)

The 700 Hz problem is specifically related to the new Mark V !

On the old FT-1000MP it does not matter, what band or frequency
you are on - whenever you push a button to change the MODE from
LSB to USB or CW/U or CW/L or AM or FM or RTTY:

---> the frequency reading STAYS THE SAME all the time.

On the new FT-1000MP Mark V, when you are doing the same,

---> the frequency reading *CHANGES* with a different mode,
---> for example:
---> You start at reading 14.100.00 USB
---> You change from USB to LSB (and back): still 14.100.00 OK
---> You change from USB to CW/U: reading is 14.100.70
---> You change back from CW/U to USB: reading 14.100.00 OK
---> You change to CW/L: reading is 14.099.30
---> You change back from CW/L to USB: reading 14.100.00 OK


==============================================

==============================================

Examples:

Radio-A (Mark V) is on 14.200.00 USB
Radio-B (old   ) is on 21.200.00 USB  => Ctrl-S is OK

Radio-A (Mark V) is on 14.200.00 USB
Radio-B (old   ) is on  7.050.00 LSB  => Ctrl-S is OK

Radio-A (Mark V) is on 14.010.00 CW/U
Radio-B (old   ) is on  7.010.00 CW/U  => Ctrl-S is OK


Problems:
=========
Radio-A (Mark V) is on 14.200.00 USB
Radio-B (old   ) is on  7.010.00 CW/U  => Problem:

Press Ctrl-S:

Radio-A (Mark V) is now on  7.010.70 CW/U
Radio-B (old   ) is now on 14.200.00 USB

Press Ctrl-S one more time:

Radio-A (Mark V) is now on 14.199.30 USB
Radio-B (old   ) is now on  7.010.70 CW/U

Press Ctrl-S one more time again:

Radio-A (Mark V) is now on  7.011.40 CW/U
Radio-B (old   ) is now on 14.199.30 USB


Which means that the old FT-1000MP is taking over the
frequency correctly, while IMPORTING a frequency into
the new FT-1000MP Mark V either increases or deducts
700 Hz depending on the mode.

======================================================
A workaround could be creating a new radio scheme
"FT-1000MP Mark V", which is sending an additional
frequency correction by 700 Hz, if the "different mode
condition" is met...   :-(
======================================================

I have checked if you could change the FT-1000MP Mark V
behaviour by a menu setting, but failed so far.
On the other hand it is useless to just change the
DISPLAY OFFSET setting, because the frequency READINGS
are correct - related to the AF audio output...

Hope this helps...
