[Heath] SB-100 vs SB101/102

[Glen Zook]

Heath did have a modification kit for the SB-100 and HW-100 to add the CW filter capability.

It was noted in a recent post that the SB100 did not have the CW filter. 
Well, I have a SB-100 with such a filter which was actuated with the notorious 
lever actuator which usually breaks. On the front panel is small overlay panel 
which has the labeling for the filter. I don't know if this was a mod kit put 
out by Heath for late SB100s, a custom job or a prototype as I purchased this 
unit used. Several years ago I furnished a picture of this to the fellow that 
wrote a book on Heathkits and he included it as I remember.
 
I do know that Heath did put out a mod kit for the SB100 which made the 
best position of the driver/preselector to be nearly the same for both transmit 
and receive. The kit had a resistor, diode and maybe a capacitor. I did have 
(don't know if I still do) the manual for this mod.
