When I plug in the 13.8V PS the radio shows 13.8V for only 1 second and
drops to 10.4V. Eneloop batteries all OK 1.29V individually. Running a 4
hour charging cycle it turns off when voltage reached and shows the
dropped voltage. When batteries removed the voltage shown on display 13.8V.

ARRL may initiate changing that law. Proud hams could drive that change.
With current LDMOS devices lots of money can be saved with one stage

Heil Proset is great with K3 and KX3 both. Different settings but each
sounds excellent. You may not like Proset on portable, it is large for
that, use a small, light computer headset with electret element if you
prefer VOX. I use a small Panasonic that requires more mic gain than
than Proset.

Found an impressive HF PA, HVLA700Q, looks ideal for QRP rigs like
K3/10, KX3 as requires only 10W drive for 700W output. They give
attractive 5 year guarantee. Is it a silent PA, any experience? Would be
nice having a dBA noise specification with max. power of the factory
built PAs.
Firmware works OK, I set the wrong AGC not the one is for cw. Thank you
for support.

You're right: even if the filters don't have matched offsets, you can use
diversity mode.
But the main and sub synthesizer frequencies will usually be separated by a
