[1000mp] RTTT tuning meter adjustment.

[W3JXP]

Hi All:
I set up my FT1000MP markV field last night for FSK rather than AFSK from 
the sound card. I'm using TrueTTy software and it's an easy setup. In the 
course of the testing I was getting reports of being slightly off frequency 
when I was tuning in a station. When your running FSK you must tune the 
receiver to the station, rather than just point and shoot on the waterfall 
display.
Anyway there is a simple adjustment of the RTTY tuning meter on page 85 of 
the manual. It uses the beep tone, which you set 2210Hz for 170Hz shift and 
has you adjust a pot under the trap door to light up the center arrow on the 
tuning display. It is a bit touchy to do, but in the end I got set up and 
the center arrow would stay light for as long as I could stand to listen to 
the tone.
But here is the oddity, if I shut off the tone with the menu command and 
turned it back on, the center arrow would not come back on. One would think 
it would but it doesn't. To get it back I have to adjust the pot all over 
again. In the end it may be the way it supposed to work so the question is 
has anyone else noticed this behavior?
