No-tune antennas such as the BW all-band no-tune folded dipole
generally waste half the power
fed them in the termination resistor. However, you can get a good
all-band high-power
memory tuner for much, much less than what I would imagine that Alpha
tuner will cost,
and feed an all-band

Have you checked the setting of the K2 CAL TPA menu? It should read the

I don't think the finals are the problem. I would check Q3 for good
soldering and the value and soldering of R5 - make certain you used the

The soldering at U1 pin 5 should also be checked, and be certain U1 pin

If there was a marginal solder connection, it may have worked but with

Yes, investigate those components that I mentioned. If the temperature

Ok. I will do that. Anything is worth a try

If it is either the Heil Proset Ic or the Elecraft Proset K2/3, then you
need to turn bias on because it has an electret element.
If it has a dynamic element (often marked with an HC4 or HC5
designation), then no bias is required (and should not be turned on).
