[Elecraft] K3 NB

[Ramon Tristani]

Great recording. Just had to follow your email and listen to the sound at the same time. I have had my K3 for over five years now (Serial No. 4416), a kit that I put together myself, without ever having any problems whatsoever. For questions, a simple call to Elecraft Customer Support has sufficed, a reply with instructions and solutions, if any, have arrived within minutes. I have had Kenwoods, Icoms, Yaesus, Galaxy, Collins, you name it, and never ever have I dealt with such a dedicated company whose products are worth every penny I have paid for. They have to be commended for the high standards of quality and outstanding customer support. I have been a ham since the early sixties. My comment is based on my own experience. In all those years I have never dealt with a company and products that even compare to Elecraft. I only hope they are here to stay. 

73,
Ramón E. Tristani Sr.

At 6.7seconds in, the noise blanker is switched on (set at dsp t2-6, IF narrow 3). At 21.4secs in, the mode is switched to cw - the audio tone remains the same, and the bandwidth changes to 900Hz.  At 30.5secs in, the APF is switched on until 56.4secs.  At 61.5secs we revert to usb mode and at 68.3secs, the noise blanker is turned off.]
