Another quite practical issue is setting the blinking frequency, as the pot on the oscillator seems too touchy. I set a signal generator to 20 GHz, which was fed from a GPS frequency reference. The output of the signal generator was then fed into the counter. Getting the counter to read within 100 Hz is extremely difficult, as the tuning control is too coarse. As I write the frequency counter is reading 83 Hz higher than 20 GHz. To be honest, that's "good enough" for what I am *practically* going to need. But I would like to do better if possible.
