I should have credited the loop idea as you did, Paul. I don't know who it was, but thank you.
I would leave my translator on all the time if it weren't for my La Crosse -- whose reception would be ruined. In my system, BTW, a resonant tank precedes a FET amplifier, which provides the antenna current. I have found, as others have, that the frequency must be good to several Hertz. So I use a crystal controlled CMOS gate oscillator to generate the RF.

A loop in the basement as suggested by a time-nut. Radiations quite low depending on the floor of the house and walls its 100uv to 30 uv. Did resonate it with a cap that seemed to improve things. But no matter it works for what I need and the clocks are happy. I leave the simulator on all of the time now as no matter the time of the day or battery change the clocks lock in the 3 or so minutes. Since I don't own an official lacrosse no issue here though perhaps mid January I will pick one up cheap... Chuckle. If I do I guess l'll have to build a BPSK version. Oh hang on there thats what the de-psk-r is. Just add 60 KHz. Actually depending on the clocks cost as they get dropped maybe not a bad idea. Have fun with your system.
