That is odd, because the Koss SB40 appears to be a Yamaha CM500 with a dynamic

“The modulator” means “the modulator code in the DSP” of course. If the
compression is done by RF limiting, I expect that is also done in the DSP.
The ALC you are describing is transmitter gain ALC. That is different from

oscillation is to have a slow
time constant on the sensor. That means that it just cannot respond quickly, so
overshoot will happen and will cause splatter. With audio ALC, the control loop
is an integrated whole and can be designed to be quick and stable.

Looks like the wall wart cannot provide the 2.5 A needed for transmit. The drop
to 10 V automatically triggers dropping to 5 W.

Are you sure your ladder line is 200-300 Ω? My calculations say that 12 AWG
conductors 12 inches apart makes 680 Ω line.

Nice analysis. For Eneloop Pro batteries, with 2550 mAh capacity,
that would be 21% of capacity for the clock plus 15% for self-discharge.
Of course, whenever the KX3 is connected to “shore power”, that is
used instead of the battery.

For rope into trees, arborist throw line is great. It is lightweight and

ies are low self-discharge, with 85%
of charge after one year of storage. High-capacity NiMH batteries (often 2700
mAh or higher) can have higher self-discharge rates.

I expect he meant “existed for the KX2/KX3”.
The Heathkit SB-230 is conduction-cooled with a beryllium oxide thermal link to
conduct heat away from the anode to the heat sink.

This is a fairly early model, serial number 29xx.
Any ideas other than sending it in for repair?

Silver oxide is a good conductor, but the tarnish we see is silver sulfide,
which is a semiconductor. That causes problems at low voltages.

I’m pretty sure the first homebrew project I ever made was a switched outlet
strip using utility boxes on a 1x3. Might be worth doing that again and adding
some good filtering.
