[Elecraft] K2 power and receive strength low on 17m only

[Robin Bayer]

I obtained a well built plain K2 that has normal power out and receive on
all bands except 17m.
On 17m power is very low at .1watt and power control has no effect. I hear
a clean signal on my other receiver but faint.
On receive the K2 does receive but signals are 9 to 10 s-units down.
As an aside, the filters need alignment.
I have just started reading the manual and am interested in being able to
maintain this my dream HF rig.
