[time-nuts] Ultralink WWVB receiver manuals?

[Tom Van Baak]

Congrats on your acquisition. The Ultralink WWVB receivers are very nice. It should still work -- it's an AM subcode (not carrier phase) receiver. If you have more questions let me know. These modules were the darling of precise time at the turn of the century; before mobile phones, before GPS was affordable. Ultralink discontinued the product line within a few years when the market for WWVB-based timing dried up.

Good question on the cable. If you don't see it in the manual let me know; I'll dig out my cable and have a look. Note the inner 4 of 6 pins are Vcc, TCO, AGC, gnd.
