[Elecraft] Brief tutorial on solid state amps (KPA 1500)?

There must be some sweet spot of knowledge that could be briefly reviewed to help those of us who have never owned or considered a solid state amp and are old school and not EE.. I just sold my pair of 4-1000's (clean, linear, hot, noisy, beautiful to own) and now just have the KPA 500. So I am cur

Re: [Elecraft] The K2 sure is a nice sounding radio

The key to a "good sounding K2" is proper alignment of the IF filters. While the filter settings mentioned in the manual will produce workable filters, the best filter alignment can be done using Spectrogram (or other audio Spectrum Analyzer) and a broadband noise generator. That will optimize

Re: [Elecraft] Kx2 battery.

The battery pack should arrive about 30% charged. Our recommendation is that you charge the pack fully before using it. You'll know that the pack is fully charged when the green LED on the charger is glowing. 73, Matt Zilmer, W6NIA KX2 Program Manager On 4/24/2017 11:36 AM, Evan brendel w
