ULA Atlas V Launches GPS IIF-10 for the U.S. Air Force > The United Launch Alliance Atlas V rocket lifted off at 11:36 a.m. EDT. This is the 10th of the final 12 satellites in block II. Best of luck for a good insertion and deployment which should be happening right now. Cheers, John K5IT

>From Frank Mantlik 10/27 Bridgeport, Seaside Park - No sign of the previously-reported Western Kingbird this morning. I scoped the power plant from the park road near the white anchor, and was joined by Mike Resch and Laura Carberry. There were 2 EASTERN PHOEBES near the pipes where the kingbird had been seen yesterday.

• Monday 4/10, 6:30pm, Keystone Running Store (200 E. High St, Pottstown): Group run!

>From Steve Spector, 10/14/18, Silver Sands SP, from a fixed location along north-east edge of marsh, many sparrows including 2 Vesper, 4 White-crowned (one adult), Lincoln's, Field, and female Purple Finch.  charsjs@sbcglobal.net

No rarities of any sort have been reported except for one of the continuing Yellow-throated Warblers that has visited the visitor centre feeders this morning. Neither the Summer Tanager nor the Western Kingbird have been reported today.

Possible problems might be that a 10MHz squarewave is simply too 'slow' to be transmitted by an SFP, which expects 1.25Gb/s 8/10 encoded data. Another interesting question would be how much jitter/noise such a setup would add? Regards, Paul Boven.

Maybe $1 vs. $10 or about that. (don't say "10X" say "$9 more") The DDS does about the same thing is a PIC except that at each cycle it picks an entry from a sine wave table. I don't know if they interpolate or just use the nearest value.

What would be nice is if a cheap "box" could be found - ideally (for 10 MHz) BNC in/out and fiber connector with a wall wart for power. Maybe this a good idea for a TAPR project if someone was willing to do the design (!)
