 This driver supports the HP 58503A Time and Frequency Reference Receiver
-and HP Z3801A GPS Receiver. They use HP SmartClock (TM) to implement an

+Two-unit pairs of these are sometimes known as a KS-24361.
+
+These receivers are very old designs, dating from around 1990, so
+their GPS receiver stages are not very sensitive by modern
+standards. On the other hand, lots of them are available cheap,
+because they used to be standard kit on cell towers and were surplused
+off in the thousands.

 the receiver. The receiver responds with a timecode string of ASCII
