Re: OT2m not functioning as digi
- Can the sample file "flutter.wav" be posted on the ftp site (my audio
processing ability prefers direct file input -- I don't know how to
capture the audio as shipped from here). Alternately a time parameter
of where it occurs in the original Milan wav file would do.
We have no issue with stamping out excessive Txdelay's!!! What is the
conversion factor from command parameter numbers to msec.?
Unfortunately, if this is the case I think it is, communicating with
the perpetrator is difficult if not impossible. Or are the long TXD's
and very, low deviation in different packets?

it's time to look at the more difficult stuff. You could breadboard the
2211 circuit and see if you can duplicate the OT2M performance you are
seeing or improve upon it. The subject is "not functioning as a digi"
but I take it you have a problem with decoding signals rather than a
problem with the digi settings. However, at risk of being told that it's
"easy stuff" what settings do you have in...
SMARTBCON (I know... it's supposed to be a digi)
WAYPOINTS (I know... you probably don't have a GPS connected)
What do these have to do with decoding? Probably nothing. Heck... you
could do a DISPlay and post all of your settings.

sigh. What an attitude! It's insulting to the other people on this list.
