I've heard a couple of pretty good ideas for audible pan adapters.  However, 
I'm not convinced that any audible pan adapter will be significantly easier 
to use than the current scan function.  You scan the band, and as soon as 
you hear a signal, you hit a key, F2 by default, and that pauses the scan, 
and you'll be very close to the signal you want.  Since there are usually a 
limited number of braille cells, 40 in my case, the braille pan adapter 
doesn't land you exactly where you want to be anyway.

With the audio pan adapter, you're still having to essentially linearly scan 
in some direction, as opposed to getting a panaramic view, which you can get 
with a tactile line.

In fact, there is one advantage of the scan over the pan adapter, which is 
that you might, with the scan, be able to distinguish an amateur 
transmission from a birdy, for example.

Jim,
Just a thought about a possible means of doing an audible pan adapter.

If you have stereo sound out capabilities, you could present a tone whose
relative pitch representes signal strength and whose stereo position
represents frequency.  it could scan rather quickly left to right in how
ever many stereo positions you think practical.  It could have this
automatic scan function or a key controlled manual scan position, and
duplicate the usual pan adapter ability to stop the scan and put the radio
on the represented frequency.

Just how I'd approach it.
Ain't it nice of me to give you more work with which I can't help <GRIN>
73s and much respect for your work on this project.
