Well after observing the standard for a while there is a 1hz or so fluctuation at 10 mc's, much more like it.
I reckon this can be reduced also.
Heres a design mod I came up with for the receiver, I'm allready using this circuit, the stuff bottom right I think might be usefull for removing some of the am from the carrier which might be causing my drift, I'm thinking apply the received audio to a dual gate fet on the fron end, instead of the single gate fet I'm using, and implement a sort of high speed agc, the capacitive coupling is going to create a time shift so total cancellation isnt going to happen but I'm expecting a good reduction in modulation.
