8640-jr VFO

Started assembling a 8640-jr VFO tonight. Should have done this a month ago but been rather busy with no-related bench stuff lately. Built and tested the +6 volt strip and now onto the oscillator and buffer stages.

Located and sorted the parts for the entire project…now just need to build it, then test and measure the three stages. This is for a T5W article that VE7BPO inspired a couple of months ago.

    Its for 80, 40 and 20 meters. The VFO develops a 20 meter signal and then dividers drop it down to 40 or 80 meters.
