Well it doesn't make any sense but by using a LO of + or-150hz I do get a stable signal that at least allows me to get a sense of the stability of the carrier. I am not using the tracor d-msk-r to see this. In fact I need to relook at it may have an issue it does not seem to be doubling. A big change I made is to use a Krohn Hite 5910c arb gen that actually has an amazing stability all by itself. Have never had a manual for it. Though I see the b exists. Its set to 100 hz and putting out a nice clean sine wave. So the math is still nuts. Re-read the tracor documentation and they injected the LO 100 Hz low. So 24 Khz needs a LO of 23.9 Khz. The d-mask-r did not require any change to this setting. If NAA is transmitting 200 baud then I would expect the MSK carrier to be +/- 100 Hz. Not +/-50 Hz. Regards Paul.
