This is for driving a 16 MHz microcontroller from a 10 MHz Rb/Cs/GPSDO. 10 MHz input is likely sine; 16 MHz output is 3v3 or 5v CMOS. > > Thanks, > /tvb I would square the sine (like HP single BJT or double BJT squarers), divide by 5 with any 74XX290 or xx390, then multiply by two three times using 74XX86 XORs with one input delayed by two inverters.

from Glenn Williams w/Env Sci class: 10/3 - Stonington, Barn Island -- PEREGRINE FALCON Slow day even for common birds, though there was a steady stream of Monarchs and a fair number of raptors.

I'll assume a good 10 MHz source has to match those specs. Comments? Thanks, Dario On Tue, Oct 3, 2017 at 10:49 AM, Vladimir Rytikov wrote: > Dario, > > 10 MHz signal input is meat to be freq reference. If a radio could tell > that 10 MHz is not 10 MHz - there was no need to feed it externally.

from John and Alec Marshall: 10/4 - Hammonassett SP -- immature TRICOLORED HERON at East Beach Marsh, PEREGRINE FALCON at East Beach, immature LITTLE BLUE HERON at the pools at the beginning of the moraine trail, AMERICAN BITTERN at the pond at Meigs Point, 3 WHITE-CROWNED SPARROWS behind the nature center.

From Jerry Connolly: 10/29/09 - AMERICAN BITTERN (2) from blind at marsh between the two parking lots behind the Nature Center, WILSON'S SNIPE west of gravel parking lot directly across from "Swan Pond", HUDSONIAN GODWIT south of gravel parking lot directly across from "Swan Pond" (beyond pavillion), NORTHERN GANNET The Audubon Shop 907 Boston Post Rd.

>From Greg Hanisek 9/10 New Haven, Lighthouse Point hawk watch Hey, anybody can hawk watch when there are hawks! Days like today take, what, lack anything better to do? Anyway, only 8 raptors to show for the effort - 5 Osprey, 1 N. Harrier (imm) and 2 Sharp--shinned Hakws.
