The frequencies of the two receivers in the K3 are locked together for diversity by sending identical instructions to the two identical synthesizers which also share the same clock oscillator.
RF phase doesn't need to be coherent for diversity reception as implemented in the K3, because the two signals are only combined at audio frequency (usually between the operator's ears). There may be small difference in time delay (group delay) through the roofing filters in the two receivers but in practice this doesn't seem to be a problem. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:[email protected]] On Behalf Of >DaleJ >Sent: 18 January 2015 09:28 >To: [email protected] >Subject: [Elecraft] Diversity reception in the K3 > >Going beyond pushing a button, could someone explain how diversity >reception is accomplished in the K3?
