Hi all,
Over the past two days I’ve been deluged with requests for our K3S vs. IC7300

my subsequent offer to send out the chart, which we normally use for in-house
training purposes.

Wayne,
How much resolution is available (how many bits per sample) in the
typical modern A/D converter used in an IC-7300 or Flex?

I believe the Flex to be 16 bits and the Icom to be 14 bits, but if anyone has
data to the the contrary, feel free to post it.
Even the most expensive 16-bit A-to-D converters, operating at RF sampling
rates, can exhibit nonlinearity or even non-monotonicity in their lowest-order
bits. The usua

Gary, K7EMF, caught an error in my paragraph below. I had used ‘dB’ when I
meant ‘dBm’ (dB relative to 1 milliwatt). Now corrected.
