[Elecraft] K3: very quiet on CW

[Dale Parfitt]

I don't understand the term quiet in this instance because at HF our noise
floor is limited by manmade, atmospheric and galactic noise. If your noise
floor does not increase when you connect the antenna, something is likely
set very wrong.

Welcome to the K3 on CW!

Yes, it is that quiet!!  Try a KX3 it is even quieter!!!

This radio opened a new world for me on CW a few years ago.

Even though you don't have the CW filter, you can still utilize the filters
you have, and DSP filtering to narrow your bandwidth down to 50 Hz.

Your K3 is an amazing rig.

I have not used my K3 for CW, so I have no experience with it. So, a
couple of days ago I decided to give it a try, after all - winter is
coming.

When I switched to CW mode - things got deathly quiet. Quiet as in all
the background noise vanished - along with most of the signals. I could
see them unchanged on the P3 - but, had to turn up the audio gain to
hear them. With the audio gain up, I could hear everything that my other
rigs were hearing - except no background noise. Compared to my past
experience - this is not normal.

I am using a K3 set up for SSB and only having the 2.7. 2.1, and 6 kc
filters. Some ACG changes have been made to afford improved arm chair
copy on 75 and 40 meters.

My question: Have I been missing out on using the quietest CW rig ever
made or is there something wrong with my receiver? It just seems too quiet.

Thanks,
