Re: VK4PP uBitx LPF BANK add-on Board
I interpret this measurement from Glenn:toggle quoted messageShow quoted text
"-32dB from one set of contacts to the other. (common terminal)"
as being from KT1 pin 14 to pin 16 as seen in the uBitx schematic.
Also, interpret his -39 and -41 dB numbers to be from one relay section to the other,
which I averaged as -40dB. For example, KT1 pin 12 to pin 5.
I now suspect those assumptions are incorrect, but the analysis could easily be adjusted to for any change to those two numbers.
