[Elecraft] 160m alignment

[Graham Knox]

Gents,
             I'm having difficulty getting decent power output across
the whole of the 160m band, I can tune up the bandpass filter to get 15
watts at any point on the band but  the level drops very quickly as I
tune either side of the peaked frequency.As an example If I peak up at
1900Khz I have under 2 watts output at the band edges and a
corresponding  loss of receive sensitivity.The performance on 80m is up
to spec. so I am guessing that this excludes a problem with L3 or L4.
Yes I've checked the component values & soldering to no avail so am
looking to the list for inspiration.

        Thanks, Graham  G4cpd
