RIT control for the Collins KWM-2

If you are devoted to putting the great Collins rigs to work, and unless you are the proud owner of a 312B-5 second VFO, you'll definitely miss an RIT (receiver incremental tuning) control when using the KWM-2 on the air.

And when you are even trying to use a KWM-2 for CW, you probably wonder why you have to live with such a high 1.5 kHz sidetone frequency. Well, the KWM-2 is certainly not the best choice for a CW enthusiast, but if you insist - then there is a solution.

If you are not afraid of semiconductors (brrr...) and if you like to have a small construction project, you can solve the RIT and the CW sidetone problem in one step. And the good message is: it can be removed in case you want to have the rig in its original state again.

Here is the circuit diagram, you can also download it as pdf document.
