Re: receiver overload

The stock uBitx provides a DC path to ground.
During receive, that would be K3-12,14, K1-12,14, L1,2,3,4,  and T2.

Don's AGC fix adds AC coupling, there is no DC path:

Perhaps a 1k resistor from antenna to ground is in order there.

I'm sure it happens. But not consistently. You need wind and something

charge why doesn't the rig itself do it, at least with an unbalanced
feed?
