Gentlemen: Transatlantic test beacons need to be very stable so that the listeners over there that have the equipment can use very narrow bandwidths. Spectran may be popular but it will only go down

The notion of excellent transmitter frequency stability is critical, but so also is the necessity of having fully automated receiving systems to take advantage of the fully automated transmitting sys

What is needed is a suitable very narrow bandwidth receiver design to go with the DDS effort we are making over here with the AD9835 DDS device. I am also prepared to share in the Transmitter effort

I have only the greatest respect for Peter and his views, and I certainly don't want to begin any new and unproductive controversies on the reflector, nor to dredge up any old ones. However, it seems

I think that Andy's (G4JNT) approach to go to milli-Hz bandwidth will be very usefull in exploring the limits of what we can do with our small antennas and 1 Watt ERP limit. It may also give us some
