[Heathkit] Dx100 and 100B difference

[Bill Cromwell]

Hi Glen,

I snagged a copy of that information when you offered it here before. 
Thanks.

I don't really need to do SSB with my DX-100 but I am saying goodbye to 
my Apache because I think it would be easier to accommodate an SSB 
adapter on the DX-100 than to add 160 meters to the Apache. Maybe change 
the 11 meter coverage to 12 meters...nah.. I get nosebleeds if I go 
higher than 21.200!
