Re: [Elecraft] K3 - what power supply are you using?
I Bill, I'using a single 28A Difona ( http://www.difona.de/f_k_s.php?&language=en&ID=8a&geraet=netzteil) switching power supply for all my rigs and they all work very well. I have no doubt for a switching amp. 73 Giampiero / IW2ESL On Thu, Oct 11, 2012 at 1:09 PM, Bill wrote: > I am about to replace my 35 year old Astron 35 amp supply.

Re: [Elecraft] KX3 I/Q to soundcard isolation
I do connect KX3 I&Q directly into my MacBookPro stereo in-line without any additional isolation too and it works great without any problem at all running under a parallels desktop virtual machine. Is there any special reason to isolate this line ? 73, iw2esl / Giampiero Sent from my iPad On Oct 14, 2012, at 11:08 PM, Barry LaZar wrote: > Jeff, > I don't know what problem you're having, but I run without any > additional isolation with no problem.

Re: [Elecraft] KX3 I/Q to soundcard isolation
Do you have this flood of noise in any laptop power condition or only when operating while battery are charging and no noise when running with battery power alone ?
