Good Evening,    Once again the two bands were quite different.  Twenty meters had a steady roar of QRN with a little slow QSB.  Forty meters was not as strong as last week and had two rates of QSB.  Slow and steady waves like on twenty meters but a fast warble too.  Fast enough to cut

Hi John, The K3/K3S "RF Gain" control doesn't control any RF stage at all... It actually controls the gain of the 8.215 MHz IF amplifier immediately following the 8.215 MHz roofing filters which then controls the 8.215 MHz IF signal level feeding the 2nd mixer. See the K3 RF Board

A strong suggestion from a network engineer. Major NTP servers like time.nist.gov are the most accurate clocks, but they aren't meant for everyone to use -- that's just too much traffic and latency hurts their accuracy if they're abused. A huge number of highly dedicated time-geeks run over
