[Elecraft] K2: no more problems with 30 and 20m filter!

[Guido Tedeschi]

Hi Guys,
    I solved the problems with 30 and 20m filter.
It was the K4 relay that, for some reason, interacted negatively with L9
that it was impossible to tune.
After unsoldering K4 and checking the filter with a signal generator, a
50OHM load and an oscilloscope, I've seen that the filters tunes and works
fine on 30 and 20m.
The only issue is that it was impossible to remove K4 without breaking the
relay... :-(
I substituted K4 with one "stolen" from an unbuilt K160RX kit of a friend
and all works fine (Eric, when the owner of K160RX will order a rev. D
upgrade kit, please send also an OMRON G6HU-2...thanks!).
Now, after correcting some other building errors,  the basic K2 is finished,
aligned and it works very fine!
This evening, I will add, check and align the KSB2 and then I will return
his K2 to the owner.
Thanks to all for the suggestions
Ciao and 73
