Gary said: >The old HP141 will do it but even it has stability trouble with the 1.2 ghz rf head in it. < The oscillator that downconverts the first IF to 500MHz is about 1500MHz, and is free running. It's surprising that it manages the stability it does. One of these days, I'm going to do a PLL to stabilise it. 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
