After a years work I am three logic devices from final testing a 5 MHz HP standard (5248L) slaved to GPS After many months I am now two types of devices, capacitors smd type, from getting your DDS boards running. With that setup I will have the stability you request. All things come to he who waits and also to he who works hard. Having started with nothing 15 months ago I will let you know when I am able to transmit to the standards needed. Larry VA3LK
