Fellow time-nuts, I spent Easter leave to go on a road-trip, taking me by fellow time-nuts Björn and Poul-Henning, and naturally lots of other good friends. On my way out I lent Björn one of my HP5065A and a SR620. On my way back I looked at his measurements. One of the things which was

I have updated my GPSMonitor firmware project. Version 0.3.3 released last year allowed to display local time, by applying the time zone offset and the GPS offset (15 seconds at the time). However, GPS offset was hard coded, so it would require a reflash after a leap second. Version 0.3.4

Rich, That odd ball frequency works out for 1401.51 MHz for low side injection for L1 and high side injection for L2 with the same 173.91 MHz IF frequency. Neat trick for a combo L1/L2 receiver, huh? But the Jupiter T only works on L1. They had other models that did both L1 and L2.

Yes, a bias T is needed. The same is true for some hand-helds like the Garmin GPS-60CSx which also only put out 3V. 5V antennas like the Synergy VIC-100 have very low gain at 3V. 73, David N1HAC On 4/9/12 11:29 PM, lstosk...@cox.net wrote: How's the best way to run an older 5V antenna
