[AMRadio] SB-10 Modification (was DX-100B on Phone - bad audio distortion / oscillation)

[Mike Sawyer]

Rick, (et al),
    Maybe I was asleep, did your DX-100 have the actual Heath modification 
installed? Mine has the switch installed although it remains fixed in the 
AM/CW position, (for good reason!) The 'spot' switch also served as a way to 
tweak and peak your driving circuits. You could tune the drive section 
before 'throwing the plate switch' (in old buzzard vernacular).
Also, if you have a SB-10 a good meter, I would be intersted in the meter. 
The SB-10 I have is intact except for the meter. I though I read somewhere 
that you can easily modify them SB-10 into a phasing rig. That would be 
interesting!
