Re: [time-nuts] Question on GPS and reference standards

Not knowing all the particulars and requirements, I may be off base, but instead of spending money trying to frequency stabilize a 20+ year old radio (HF-80), wouldn't it make more sense to spend it on a modern, inexpensive HF rig? You can even get a TCXO option for some rigs. This should be stable

Re: [time-nuts] Question on GPS and reference standards

A conjugate regenerative divider will have asinewave output. It only requires a mixer an amplifier or two and a couple of bandpass filters. It will have lower phase noise than all(?) alternative techniques. Bruce Tom Van Baak wrote: A good question for the group... /tvb Hi: I have both a

A good question for the group... /tvb Hi: I have both a GPS Frequency standard (Trimble Thunder Bolt) which outputs the 10 MHz reference and also the 1 PPS signal. In addition, I have a Collins AEU unit which has a 10 MHz Rubidium reference inside. Both units work well and produce a very accura
