[Heathkit] Heathkit SB 220 and SB 201 amperage draws

[Steve Beveridge]

Hi Dave,

Yes, there is a problem with the SWR when the SB-200 is in-line.

Have a look at "Heathkit SB-200 Tuned Input Circuit Modification" by Tom
Boza - NE7X.

He's carried out an excellent analysis of the problem - and more
importantly, the fix - for the SB-200. Just a matter of changing a couple of
caps, as the mis-match isn't a problem on all freqs.

Cheers

e-copy.
