Dave,
Thanks for the info. Guess some of the guys do not have this problem.
Kind of surprises me. Could there have been a mod performed in later
versions of the FT1000MP? I use the Array Solutions SO2R box and wonder
if it could contribute to the problem too?
Last night nothing worked to get NA synched, had to exit NA and restart.
No problems after that.
Keep this problem in the back of your mind if you think there could be a
solution within NA. No hurry, but some of us would certainly your effort!

I think this problem is related to the communications protocol Yaesu
uses to talk to the radio. It's different (and IMO, inferior) to that
used by the other manufacturers.
The communication protocol varies between manufacturers, but most are
similar. The data packet starts with some sort of an ID byte, and
ends with a termination character. With this type of protocol, NA
knows the message has ended when it receives the termination
character. When this happens, it starts back at the beginning of the
buffer looking for the ID byte, parses the data based on the type of
packet indicated by the ID byte.
Yaesu uses no termination character. Instead, Yaesu's protocol exists
of five bytes for every data packet with the first byte as the ID
byte. The other characters can be anything, so there is no way to
detect the end of the packet other than by keeping track of the count
of received characters.
I've seen the problem Ray and others have described with my
FT-1000Ds. I think that when you turn the radio on or off with NA
running is that the program and the radio are getting out of synch.
I'm not sure of the exact mechanism for the problem. I did try to
account for errors which would upset the process by clearing the COM
receive buffer each time the radio is polled, but there must be
something I've overlooked.
EVERY time this has happened to me I would exit NA, then restart the
program and all would be well. (Note: you don't have to reboot) I'll
admit this is a little more awkward than Alt-F1 then Alt-F2 but it
works every time.

I am having a problem that occurs when I turn off my FT1000MP that is
interfaced to NA logging software. I keep the computer running since
it is my interface to Packet. Later, when I turn on the FT1000MP, the
software does not sync with the band & mode displayed on NA. The CAT
LED does flash as it should.
The only way I can get the two to sync is to press the ALT/F1 or
ALT/F2 (band up/down) a number of times, then it may sync. Pressing
the band / mode buttons on the radio does not do it.
Is there a command, procedure or other process that will get the
radio and software to sync? It is more likely to be an NA problem or
FT1000MP problem? Anyone else have this problem.
