It appears that UTSource has the U4226B in stock under several manufacturers, including Atmel.

Thanks to another list memo, I got the basic manual. Got it fired up and while it does things, I think there's a problem. The S Meter is pinned all the way over to the right (very, very strong signal) and stays there no matter how I shield the antenna. And I never see any decoded bits. I hope the receiver chip (U4226B, unobtanium except from China) isn't shot. _______________________________________________ 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.
