Then you are a lucky fellow, Ed. My VFO NR=ON is not nearly so effective and neither can I advance the AF gain to 40 without horrible distortion - my usual audio gain runs around 20 and the artefact is clearly audible at that level.
I guess this suggests some considerable variation between units. You are fortunate. 73, John VK7JB >>VFO NR=ON silenced VFO tuning noise on 28-MHz. I had to increase AF gain to 40 to listen and there may be a hint of it there with no antenna connected. NO way I will operate with Volume set this high. Typical AF Gain = 18 to 20 (using amplified computer speakers). 73, Ed - KL7UW ______________________________________________________________ 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
