Re: Mode L Transverter



When I was at Dayton, SSB said they did not plan to import any more of
these, and Down East told me their new design would not support operation at
1268 only 1296.  Does anyone know if this has changed?  Both outfits have
listed these on their web sites for a long time - apparently that does not
mean they are available.  In their defense these are small outfits and
updating their web site is probably not their top priority.

Please keep the list posted as to what you find, as many of us are looking!
