[Elecraft] K2/100 - low power 15m only

[aj4tf]

Using a 50 ohm dummy load. 
In tune mode, with KPA100 bypassed (power control to 10W out),  power out is
OK on all bands (~10W).  

When the KPA100 is engaged, all bands have full power output except 15m (21
MHz)... it tracks up to about 50W and peaks there.  The other bands on the
LPF in the KPA100 (10m and 12m) are OK, getting around 95W out at 100W
setting.   

Confirmed with external wattmeter,  it agrees with K2's power reading in
tune mode.

I haven't opened the case up yet,  this one has me scratching my head... any
ideas out there?
