Re: [Elecraft] K3s - 80W on 160 - Resolved

2016-12-21 Thread John Kaufmann
I use a 6-foot run of 10 gauge cable between my power supply (the Astron RS-35M) and my K3S. With my Fluke DVM, I measured the voltage difference between the power supply output terminals and the Power Pole terminals inside the radio. The difference is only .03 or .04 volts under maximum current

I had the same issue with my K3S. I was seeing 80W maximum on 160 and it would not drive my AL1200 to full power (1500W). Redoing the power calibration did not fix the issue. Elecraft Tech Support told me that my K3S was within spec but that increasing the power supply voltage could yield m

My advice on Solar City is to avoid them at all costs. Their systems, manufactured by SolarEdge, generate horrendous broadband RF noise. One of my neighbors installed a Solar City system on his house and ever since, I've been plagued with extremely bad RF noise, especially on 6m, whenever I beam
