Rubidium frequency standard

10.0 MHz reference frequency standard to lock up the x-band radio. Tests show within 10 Hertz accuracy at 10368 MHz. We should have no problem find Paul's frequency. Warm up time to "lock lite" is about less than 5 minutes from cold start. This is a stand alone unit which Paul can also use for running his frequency counter time base when needed. It uses a linear 24 power supply for power and a small fan running at 8 volts keeps the air moving without making much noise.
