I've just had a very pleasant off-topic interaction with Keith VE7GDH, and there's no way to take it off-list. Can we please have facebook-style ability to "pm" (private-message) - right-click-on-name

Re: BITX QSO Night, Comments
Couple of points, yes the Bitx is quieter, have heard dx that my FT1000

Re: Automatic RF Attenuation Mod for Bitx40
Jim first referenced that other circuitry in this post: ? ?/g/BITX20/message/31875 ( /g/BITX20/message/31875 )

That's the average time it takes for the hole or electron to get swallowed up.
You would have to take it down to

Jim,
for the PIN diode to work properly as a variable resistor, and not rectify the RF the so called carrier lifetime n(minority carriers ??)? is an important factor.
