2010 SSB variable step mod

--------------------------------------------------------------------------------

Preliminary experiment with 2010 SSB suggests the following combos to replace VT1 to allow a RIT control on SSB.



pot      fixed R
---      -------
5k         12k          wider adjustment range
2k         13.2k        less adjustment range

These are based on SSB reference of 1.8 volts. You will have to vary the fixed R if your SSB voltage is different.

More later when I get parts. VT1 is on an umbilical cable waiting.

Thanks to Ken Zichi, who several years ago passed along the general idea that a RIT mod was possible.
