Re: [Elecraft] KX2 on JT65 & JT9 ??

I ran extensive frequency drift measurements on the KX3 in 2014, purchasing an aftermarket heat sink for my KX3. After running the temperature compensation procedure I reported: I re-ran the JT65 testing sequences to measure frequency drift after temperature compensation was done.

Wayne/et al: I run JT9 and JT65 with my KX3 often on 160 and 80...I had the temperature compensation performed at the factory when I purchased the rig and I utilize a cooling fan when running the JT modes or running a freq during a contest; I loaded Dimension 4 s/w for extra time stability. No

Wayne I would imagine a bit of cooling on the KX2 end plate will help also? Heat sink... Happy to see it is within limits for WSJT modes without freezing it!! Hi hi Dan VA3MA > On May 29, 2016, at 11:35 PM, Wayne Burdick wrote: > > I'm glad it's working. But just in case,

I'm glad it's working. But just in case, we will also be providing an optional extended temperature compensation procedure for the KX2. 73, Wayne > On 2016-05-29, at 22:37, Luke wrote: > > Hmm, not sure why it cut out my message. Here's what I wrote: > > I've used my KX2

Re: [Elecraft] KX2 on JT65 & JT9 ??

The moon bounces around and causes some pretty good doppler. Good thing that JT65-HF also has AFC built in. http://www.packetradio.com/pdfzips/jt65-hf-setup.pdf *AFC enables automatic frequency control and will attempt to follow a signal that exhibits drift. Its original intent is to compensate

Re: [Elecraft] KX2 on JT65 & JT9 ??

Dan Issues with not being able to communicate with JT65 have nothing to do with frequency stability. It has to do with just not being heard. :) Like all other digital modes, you require Transmit and Receive Audio and a PTT line. I would be very very very surprised that a KX2 can't handle

Re: [Elecraft] KX2 on JT65 & JT9 ??

I don't believe that JT65 frequency stability at HF frequencies will be an issue. The documents say that the JT65 bandwidth is pretty generous. I've run JT65 on my Softrock without issue. Mike va3mw On Sun, May 29, 2016 at 3:46 PM, Phil Wheeler wrote: > One of the eham
