[Premium-Rx] Diversity Reception

[john phillips]

The usual diversity method is two or more receivers. But apparently it can be done with one receiver by switching antennas. 

I refer to a construction article in CQ Anthology, The Best of CQ 1945-1952.
This booklet was published in 1958, and in it there is an article by  W . Roderic Bliss , W0SNH  who constructed a flip-flop circuit using 4 tubes
to switch the antennas depending on which one was supplying the strongest signal. There were two antenna inputs, one antenna output and an A.V.C. input.  
It worked quite well for him on AM, FM , and frequency shift keying but not CW .  The unit accepted a wide range of freqs. from 
3 to 30 megacycles.

A rather novel approach.
