Re: Anderson PowerPole color scheme?
In fact, for any two-pin PowerPole, once you set the 'zero voltage' pin, there are eight possible orientations of the 'power' pin around it.
Only two of those orientations can use the roller pin for

Not sure if the resistors I mailed are not smaller than 1mm 0402. Hopefully the are the right size.

Wayne, you can't read RF with a DMM. You need to make an RF probe for the meter if you want to. Google "RF probe" for lots of schematics. The diode can be a silicon switching diode (1N914,

If you were actually reading 0.115 microFARADS, the cap is actually 11.5% large.

Re: Anderson PowerPole color scheme?
I cried when I saw the various colors being used. I have some fence chargers that use Black for plus 12 DC and white for ground similar to AC.
I have a large number of lipo batteries with XT60

Re: #qdx Passband AF filter

Thanks, Alan.
Something I hadn’t understood - that the low pass filters as well as the band pass filters are active during receive mode…
My audio and RF sweeps attached for reference… not sure
