Q90 is the one that would fry if the antenna was hooked up and a nearby QRO station was operating.
Or a nearby electrical storm was operating.
Q13 of the Bitx40 often blow in this way.
The back-to-back diode fix of the Bitx40 is not such a good idea on the uBitx because
the uBitx is wideband up to the 45mhz filter, and the diodes can distort all that incoming RF.
We don't hear much about Q90 blowing on the uBitx,
likely because the diodes in the first mixer conduct before there's real trouble.
Here's an old thread on this: https://groups.io/g/BITX20/topic/7715656
