[Elecraft] Elecraft K3 support

Dear Elecraft Friends, Up through last weekend I had been operating my K3 #820 with MCU 4.31 and DSP 2.72, firmware that dated from March 2011. I was content with my K3’s performance, and saw no reason to upgrade. But Reflector reports praising recent improvements in NR and NB operation

[Elecraft] OT: Quiet 12V-to-5V converter

Dear Elecraft list members, The recent thread on noisy switching power supplies leads me to a related question. My son n8fyk, who teaches radio astronomy, has set up a project with his students. They are using a 15m direct-conversion Radio Jove receiver in the field to monitor radio emissions

Re: [Elecraft] OT: Quiet 12V-to-5V converter

Thanks to all who responded to my query. At this point I plan to follow Jack Smith's excellent recommendation to build a DC-to-DC converter based on the LM-2591 chip and do my best with appropriate filtering to keep RFI from getting out of the box. I appreciate having the excellent resources

Re: [Elecraft] OT: Quiet 12V-to-5V converter

Thanks, Fred. The LMZ12001 does look attractive. The best solution may be for me to buy their LMZ12001EVAL/NOPB evaluation board. See http://www.national.com/pf/LM/LMZ12001.html#Boards I will, of course, add appropriate input and output filtering. 73, John, no8v - From: Fred Townsend

Hi Kevin, Jean and I had been in Kalamazoo and returned to Alma too late for me to check in to ECN/20. I tried for ECN/40 and think I heard you announce the net, but you were so buried in QRN that I could judge it was you only by the rhythm of your sending. I tried to respond, but am not sure

[Elecraft] KX2/KX3 built-in speakers

Dear KX2 or KX3 owners, If you own a KX2 or KX3, do you find that the built-in speakers produce sound of sufficient loudness and good intelligibility? I do not (yet) own one of these fine radios, so I must ask others for this information. Thank you and 73, John, no8v
