Thanks Dave. I agree. I have one version that simply spits out up to 100 pulse periods to a serial port. Then it's easy to see everything at a glance. The period between packets is easy to locate, etc,,.

Even fiddled with one version that actually printed out working PBP code to reproduce the data packets, adjust for various carrier frequency, etc. Was fun. Just cut & paste and viola...;o)

That sounds like a pretty nifty PC app you wrote a while back.
