I operate 2m-eme with JT65 and will be very interested to see if I can see improvement with the new synth.
I'm guessing not unless you see some direct (tropo) signals.
JT-65, like all weak-signal modes, greatly benefits from low phase-noise in a receiver (typically from the LO).
On HF JT65 and JT9 as well as 6M tropo, the improved phase noise should be significant doe to the lower reciprocal mixing ... the strong signals in the passband will not raise the noise floor as much. 73, ... Joe, W4TV On 2015-02-13 5:53 PM, Edward R Cole wrote:

Nor will I part with my sub-rcvr as its integral to my dual-polarity adaptive reception using JT65. I use diversity reception with receivers connected to different polarities. The sw that provides adaptive reception is MAP65. 73, Ed - KL7UW From: "Doug Turnbull" <[email protected]> To: "'Richard Thorpe'" <[email protected]>, "'Elecraft List'" <[email protected]> Subject: Re: [Elecraft] KSYN3A Message-ID: <685CC641927645DDA5FFB8A3A5128C80@DOUG1> Content-Type: text/plain; charset="us-ascii" Dear OMs, In no way would I part with my sub-receiver. ======snip======= A few interesting questions have been asked - is there any advantage for JT-65 with the new board? =====snip======== 73 Doug EI2CN 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
