[OKDXA] More Questions from a nu-be

Thu, 22 Aug 2002 17:51:28 -0500

Thanks Coy. I ordered a manual for the SB-220 from W7FG.
>From the information I have gathered, their was a kit available from
Heathkit to add 10 meters to the 221s.
Basically was SB-220 parts that included the wafer switches and the tuned
input and output coil's .

The only parts available for this mod today are the wafer switches from
Harbach.

The 10 and 15 meter coils are said to be the same for the 220.
This seems likely because the 15 meter coil is the 11 meter sealed filter on
the 221.
the manual should clear all of this up.

I am not in much of a hurry to get done, besides tinkering is half the fun.
