[GPS_Standard] Bob AE6RV's PLL version

[Randy Allen]

Hello all,  I'm subscribed in digest mode, so this isn't threaded as it should be, but in response to Bob - AE6RV and his work to modify his standard to a PLL version, I just wanted to let Bob know that I'm very much interested in that work.

I just finished my Freq Standard based on Bert's stock code and using a Motorola Oncore VP GPS receiver and an HP-10811 dual-oven oscillator.  My goal is to also tinker with it and refine it over time.  I had a pretty poor GPS antenna location so I just put a timing antenna up on my anemometer mast 40 feet above the ground here to get above the urban building shadows.  Helped my accuracy quite a bit. (less jitter, now).

I'm currently working on Bert's UTC Station Clock but I'm writing my own code in ASM as that's my preferred "language" and using a PIC18F1320 vice the 1220 that Bert used.  That project will use a Motorola GT+ GPS Receiver.

So, some encouragement to Bob to let you know I'm watching and look forward to your releasing your designs when you feel they are ready.

Thanks also to Bert for some interesting projects.

73, Randy, N4TVC
