Had a visit by a Northern Mockingbird. It flew out after about 10 minutes but may be back. Seemed to be after the holly berries. Seen at: 1805 Norfolk County Road 19 West RR3 Vanessa

Any idea on what would be a preferred (stable) device for a 10 MHz phase detector? I know that many use the 4046 (which has amongst others an XOR intetgrated) but what are the exact pros and cons of the different approaches compared to a (example) SOT-23 type 74HCT1G86? 73s Achim, DH2VA

I only have a really good 10 MHz OCXO crystal oscillator to distribute, so about -120 dBc at 10 Hz, -140 dBc/Hz at 100 Hz, - 150 dBc/Hz at 1KHz, and -155 dBc/Hz noise floor. No maser or cesium clock, living in the world of practical realities here.

compare 10 MHz standards.
