Guys, My needs are pretty simple, i need to put the output frequency of my qrss beacons into a 100 hz sub band within my chosen band of operation - mostly 30 meters. The beacon puts out a morse id in the form of a 4 Hz square wave with a dot length of 3 secs or more. With a calibrated frequency counter accurate to 1 Hz this is a breeze. So a simple eyeball check is ok...though a simple logging capability would be handy so I can see how the output frequency varies with temperature. I am pretty sure I can do it all with a simple microcontroller and an LCD display plus a prescaler. Time to break out the Arduino..and cut some code...
FWIW QRSS is a weak signal mode, it is possible for signals < 100 mW to be received globally. My beacon uses a mere 3 transistors and a crystal plus a handful of passive components. It puts out 100 mW. 72/3 de Steve g0xar -- It is vain to do with more that which can be done with less. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
