A T-mobile hotspot is probably easiest. With 5G, I have measured speeds up to
700 megabits and typically around 300 megabits with the occasional dip to 100
megabits. $50 per month.

I seriously doubt this is an RF issue. TV is all digital and has no discrete
audio carrier. TV RF interference would sound like white noise. This sounds
more like an audio ground loop of some sort.

wayne,
After you have the K4 fully put to bed, for your next project you might want to
consider an amp that is directly driven by an I/Q stream. The amplifier will
be much more efficient (less power consumption) and you start out with less IMD
before any pre-distortion.

What is changing is the radiation pattern. As the frequency increases the
pattern becomes more sidelobes. Some of those sidelobes are bigger than the
main lobe and they radiate ‘somewhere’.

The K4 is a direct sampling radio. It has no IF. It samples directly to IQ
baseband and performs all filtering and processing in the digital domain. That
requires a very high speed ADC. In this case it is just above the Nyquist limit
for 6 meters. Getting a 16 bit converter that fast approaches
Using WWV as a reference for precision frequency calibration is a bad idea.
Propagation creates doppler effect. WWVB is better but still not perfect. A

Sounds like some internal RF feedback.

I think that this was covered. You don’t run a solid state unit into a
mismatch. The antenna tuner in effect takes the place of the output network
that existed with tube rigs.

I agree except that even at 500KW a 2:1 or greater is the norm with open wire
line.

I would disagree. Most high power commercial operations use non-resonant
mismatched antennas. Typically there is either a tuner at the antenna or open
wire is used.

With proper forethought, they can. Proper location of ‘buttons’ on the screen
and an overlay template could provide enough tactual feedback.

It is easy to run FT8 or other digital modes on a Raspberry PI. Very
inexpensive and very small.

I’ve read a lot of interesting ideas relating mostly to features. Here are some
cutting (or should I say bleeding) edge ideas.
The most radical would be to eliminate linear amplification on transmit.
Instead, go with a class E design and in DSP generate EER compatible signals.
This is how very
When I was in high school my first station was Collins S Line and a triband

This would be well suited for the use of SNMP.

I’ve been using touchscreens for 35 years. My experience is not what you
describe. Actually it is very much the opposite. Mechanical switches are the
least reliable.
