The GPS reference we used was engineered by N6GN specifically for members of our 2 meter WSPR study group listed on http://www.qsl.net/kp4md/144_mhz_wspr.htm That discussion thread can be followed at https://groups.google.com/forum/#!topic/2-meter-wspr/-hDK071K1iM
A ready made solution to produce a 116 MHz local oscillator locked to a 10 MHz GPS disciplined reference is N5AC's VHF ApolLO at http://www.n5ac.com/blog/products-page/apollo-synthesizers/vhf-apollo-assembled-tested/ Carol KP4MD On Tue, Jul 2, 2013 at 3:50 AM, David G4DMP <da...@g4dmp.fsnet.co.uk> wrote: > Hello Carol - > > Thank you so much for your msg on the Elecraft reflector; I found your > slide show most interesting. > > I use my XV144 with a K2.
