[Elecraft] Frequency reference for the K3 directly off a GPS

[Sverre Holm (LA3ZA)]

I've got some questions about the type of GPS module I'm using. It is a ublox
NEO-7M. The nice feature of this unit is that it has a programmable output
which nominally excites an LED at 1 pulse per second, but which also can be
programmed to 10 MHz. That output is not connected, so one needs to make a
connection to it oneself.
