I want to build a vcocxo, I have built a satisfactory voltage trimmed xtal osc, now I need to put the xtal in an oven.
I have a very old but serviceable cathodeon oven, the connections to the xtal would mean having leadout wires to the board, 1 to 2", do I run 2 wires direct back to the 'hc00 chip oscillator or should I twist them?.
I'dve liked to have put the 'hc and everything in the oven but it wont fit, I'm not totally sure theres any benefit as the laoding caps and the varactor diodes being outside the oven will be subject to temp changes and thermal drift still might be an issue.
