[Elecraft] El-Cheapo signal source 7.3mhz

[dw]

I needed to make a Digi-Key order last week, so I added a little clock
osc to the order.

Digi-Key PN: X208-ND, 7.3728Mhz Clock oscillator $2.13
Dug up 3 470pF caps and a couple of 1uH chokes for a low pass on the
output.
Added small lm7085 regulator and put it into a small plastic box with 1
foot antenna wire sticking out.
Its rock solid from start-up.

I used it last night to check and reset my K2 BFO filters.

I know others really prefer the spectrogram software, and some day I
will try that but for now I'm really happy setting the K2 BFO filters
with the little signal generator.
