10MHz/1MHz Calibrator/ Marker generator.<br />
By John R L Walker ZL3IB<br />
A simple frequency standard can be a useful accessory in the ham shack.<br />
Similarly the ability to include some sort of frequency marker into a spectrum<br />
analyser displayed is very helpful and this can be done using an external<br />
signal source. However an internal marker is handy so I constructed a very simple 10MHz/1MHz<br />
marker generator. This used a 10 MHz crystal salvaged from an old computer and in my unit produces<br />
a 'comb' of peaks on my spectrum analyser to over 350 MHz.<br />
