Frequency Standard

I was recently given a populated project board by Steve G0YXA. I boxed up the Howes XM1, frequency standard and recallibrated it.

The circuit is pretty simple.

The GQRP group have the HOWES project documentation and Tony/G4WIF will supply it upon request you you want to have a go at building one.

It makes the callibration of a homebrew RX dial so simple. I also used it to zero beat a homebrew TX to confirm the TX frequency.
