Igor, Minus 10C is about plus 14F, which is well below freezing. I would think that was adequate for a good test of output at cold temps. The experience that I cited about an early rig not operating for several minutes was at about minus 30C or colder. It may have been pre-vfo days, and could

It may be better to use an RF sensing switch or mechanical tie rather than software. Any latency via software could damage or destroy your gear. SW controlled switches in my view need to be tightly integrated to prevent potential damage. Sent from my iPad > On Sep 24, 2016, at 7:20 AM,

To answer the battery question. The battery was at about 11.5-12 volts and did not show noticeable voltage sag when transmitting (SSB). Note that all measurements (power and voltage) were taken using the internal meters in the cold K3. 73 Bill AE6JV On 10/6/16 at 10:43 AM,

It’s not particularly difficult to calibrate the filter. Since I built a kit KX3, I already had an anti-static mat, and also had an XG3 signal generator. You don’t need the signal generator, but it made things easy. The filter comes with an small wire loop and pigtail that permits you to

The block diagram you linked to is for hardware only; it is not a software functional block diagram. If you are interested specifically in the noise reduction, the source code for the K2's NR is open source. I imagine Lyle would have adopted a similar sort of approach for KX3/K3. 73, Matt VK2RQ
