As for noise floor- take Pete's suggestion or take your K2 to your friends
house and compare signals there.

It is likely the noise comes from your house- switching power supplies in
consumer electronics, fan speed controls, dimmers, microwave ovens etc.

Put the K2 on battery power and turn offf the main breaker into the house.

I did that today - WOW! What a difference! Unplugging my PC and
turning off the SEC 1223 ps (leaving the K2 on SLA cells automatically)
made a HUGE difference! The PC was causing 90% of the noise.

My noise floor went from S7 to S4 and new stations just jumped
out of the air.

My friend still hears less band noise than me but only by 1-1.5db at
the most now.

Now, how do I solve the PC noise problem? I guess I could spend
a small fortune in ferrite snap on chokes but I doubt I would be able
to equal how quiet it is with the PC off. If that's so, I doubt I'll bother
- it's just too easy to turn off the PC during net time......

Would a laptop on batteries work without noise?
