You are not reading this correctly.
The power displayed on the meter is integrated power in the receive
filter, just as it should be. The computation is accurate to much more
than 0.1 dB irrespective of what the display is doing
See comments below.

This also gets back to click-tuning. To me click-tuning is perhaps the
most awkward feature of PowerSDR. Our brains expect things to stay in
place and not jump from one place to another. Right now when I use
click-tuning the entire display jumps to center

All,
Is the Flex 5000A S-meter calibrated to Collin standard, i.e., S-9 =
-73dbm and 6db per s-unit?
Thanks,

That isn't how the TX relays operate. it isn't a sequencer.
When you press (assert) PTT, the TX relays close immediately.
If there is a time delay value set, then RF is not transmitted until
the delay time period expires.
Example:
TX
It looks nice. The price isn't bad either. Too bad it doesn't support 6M.

that the processor is embedded in the K3 is irrelevant - it is still an
SDR. That said, the Flex radios offer a much nicer user interface and a
lot more potential for future upgrades. That's why I own a Flex 5000A
and a 1500, but not a K3.

The 5000A uses an LM4911MM for the headphone amp. It is configured as
an OCL (output capacitor-less) amp. The advantage is great
low-frequency response without the need for very large capacitors. The
disadvantage is DC on the output.

effective resolution? That still leaves us 3 bits short of the 5000A
ADC, which still means 18 dB less dynamic range.
Maybe I missed it in the PDF file, but I didn't see a dynamic range spec.
