Re: Receiving computer detects and changes operating modem to match incoming message?
Larry - I believe what you're saying (forgive me, I'm still relatively new to NBEMS) is that the sweet spot and the high and low brackets on either side of it at 1500 for MT63-2KL adjust when the modem changes -- is that correct? (The High / Low brackets being the red, vertical lines on the waterfall.)
Assuming so - Yes - we
experienced that in the situation I mentioned at the start of
this topic. Both for the folks who received and me as the
person who sent a transmission with the wrong modem setting. In
fact when I corrected the modem to the right setting to
retransmit the message I had to manually go in and reset the
sweet spot back to 1500.
Our group decided the
moral of the story was this: if an NBEMS message is
accidentally transmitted on the wrong modem then everyone needs
to double check their modem and sweet spot settings and set them
back to MT63-2KL and 1500 before new traffic proceeds.

Another thing that get's overlooked is if your transmitted signal moves when you switch modes to outside of where thew receiving station would normally expect to see it with the RsID on. In these cases, setting the "Searches passband" check box would look in the entire audio passband for the signal. Also if you have the "Disables detector" check box set, it will disable the RsID after each successful decode and you will need to manually enable it again.
