[Elecraft] Just bought a K3/10. What upgrades should I get?

[Brian Hunt]

Oops. Sorry for the fat-finger spurious emission. 

Congrats on your acquisition!  My K3/100 is going on 7 years old and is about 500 units newer than yours. I have only the 400 Hz filter and it's all I seem to need. Like you I'm 95% CW op with some contesting and DX chasing. 

Some folks like the internal ATU but I don't have it since I use a resonant antenna or a remote ATU. 

I think the new synth improves weak signal receive. 

The biggest add I've done is the P3 and it has revolutionized the way I operate. It's hard to beat a picture of what's happening around you on the band. 

Good luck. I know you'll love the K3. 

73,
