Are you working on a portable 10-GHz ham rig, or is this part of a a fixed installation? IMO, GPS clocks are a much better solution for most people than surplus rubidium standards that may require calibration and lamp replacement. Unless you actually need portability, you might look for an HP Z3801 or similar GPS-stabilized quartz standard. Pricing will probably be about the same as rubidium, or cheaper.
Also, make sure you really need the long-term stability of rubidium to begin with. If you multiply a HP 10811 OCXO to 10 GHz and leave it running, it will typically drift less than 1 Hz per day. Some people carry high-grade OCXOs in styrofoam coolers stuffed with insulation and sealed lead-acid batteries to serve as portable standards. At home, the "cooler" is left running on AC power. -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of [EMAIL PROTECTED] > Sent: Friday, November 10, 2006 10:10 AM > To: time-nuts@febo.com > Subject: [time-nuts] (no subject) > > > Hi, > > I'm a new list member.
