Re: OCXO drift with U3S #u3s #ocxo

When I was using the plain old Si5351A synthesiser module (no GPS correction) I was getting drift reports of 0 or 1 - it was very stable. My U3S is in the aluminum case but I have a LM7805 voltage regulator on a little board with a large heat sink (converting 13.8V to 5V) which is probably keeping the heat very constant in the case.
