Again it's hard to limit this to 10. Any advice on Sabine's Gull? Golden-winged Warbler Kentucky Cape May Bay Breasted Olive-sided Flycatcher Clay-colored Sparrow White-faced Ibis Painted Bunting Phalaropes Sabine's Gull

>From Steve Spector, 10/11/13, 3:00-3:30 PM, 4 Vesper Sparrows at western edge of the sparrow lanes; also on ground in groundhog field (south side of sparrow lanes)--be careful walking there.   charsjs@sbcglobal.net

After getting to the bottom I found a locked 10 Mhz signal on U206 pin 1 somewhat of a sine wave but compressed top and bottom at 5 V and pin 2 a squared up version. Pin 1 goes off to several transistors. Also I have not looked at the rest of u206. So good or bad a tracking 10 Mhz exists. Not so easy to get to frankly. Regards Paul WB8TSL

However it is a useful concept for purposes of explanation that you do not need the 1 pps to lock up the 10 MHz VCXO - which was my main point. The Tbolt block diagram in the manual Figure 5-10 shows the 10 MHz VCXO output going to the receiver and also to the output. The 1 pps comes from the "cpu and support" circuit.

That comes to about 1 GB of raw data.
