[Collins] Re: 51S-1 improvement

[David Knepper]

Don, in my humble opinion, there are very few hams using the 51S-1 for ham
use, so I would not put too much effort into this project.

Let's try floating this idea with the Collins mail list and see what
response you get and then you could gauge whether or not there is sufficient
interest to move ahead with the R/D.

OK, guys here is your chance to give Don your thoughts.

Thanks.
