[Elecraft] K2 Antenna Tuner Question

[Bill KB9IV]

Happy Holidays!  I have a question about the K2 internal antenna
tuner.........Is the tuner for the TX
side only?  I have a G5RV 80-10 meters that has 4:1 to 5:1 with manual
tuners, the internal tuner
loads at a Fantastic 1:1.3 or less all bands even 160.
My observation is this...it's seems to load the TX side excellent but
doesn't improve the receive at
all even at a 1:1 match.....is this to be expected?  I swear the tuner would
load a #4 nail

Thanks in Advance all
