Re: [Elecraft] KX3 and JT65 (aka digital modes) ALC "problem"
I wish there was a way for when setting memories for use on psk31 or other data modes you could set power/mic/acl and have it save in the mem __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX3 and JT65 (aka digital modes) ALC "problem"
I have a SignaLink USB attached to my KX3. I jumpered the header IAW the directions on their web site. I did not turn off mic bias. It works fine. You are correct. DATA A does turn off compression and the equaliztion. There have been a few notes going around the last few days about PSK-31 and the KX3. Those notes are very informative and I suggest you do a review of them. They are applicable to all digital modes. I know I learned something that I had overlooked. 73, Barry K3NDM On 7/20/2013 11:55 AM, Stephen Selberg wrote: Hi Stephen, I used my kx3 for jt65 once when I first got it to see how it would work.
