[Elecraft] Auto Notch Revisited.

[Johnny Siu]

Hello David,

I concur with your observation.  There are many areas that K3 are better than ic756 pro 3 but the NR, manual notch and auto notch of K3 have much rooms for improvement.

When there is a strong undesirable carrier next to a weak DX, in 756pro3, I can use manual notch to 'kill' the carrier and eliminate the pumping effect on AGC.

Every radio has its own merit.  We have to accept their weakness while we are enjoying their strength.

Anyway, I would like the NR of K3 will be as good as the NR of KX3.  At one time, I nearly sold the K3 and just kept the KX3.  On reflection, K3 is still a good contesting machine at desktop size, hence I still keep my K3.

Hello,
I find I must also agree with the complaints regarding notching...  I
just cam from a Icom 756 P3, and the notching was far superior to the
K3.
