[Premium-Rx] Cubic R3030

[Mac]

Wow most interesting saga to follow,  as i also have a 3030A  I must now 
carry another legacy radio burden with me,  as well wonder how many 
times has my set been cycled and or is near or at the 15,000 mark ... 
damn it is never easy, the burden of owning old stuff ... mac/mc  
W5Merry Christmas
