A guy at work gave me his cobra 29 w/ front mic and wanted me to install an echo board and P+T. I opened it up and started adding the echo board and found that someone had added a 8.2K resister to the anode side of D-17. This is the diode that comes from the Deltatune.

What was this put in here for?

It did nothing for the power output or the modulation.
Is it to help with more or less adjustment of the delta tune? If so than why?:bdh:
This is just an AM radio so why even put in a deltatune is beyond me.

Anyone?
