Sujet : [time-nuts] Trimble Thunderbolt- Frequency lock indicator
I use an early Thunderbolt as a 10 MHz external frequency standard for my
Elecraft K3 transceiver.I would like do add to it a simple indicator which
is activated when Thunderbolt's output frequency is locked.I someone aware
of a circut diagram of a such indicator? Any other options to indicated the
LOCK state?
Tom
