[Elecraft] Burdick watch!

[Don Rasmussen]

Welcome back from vacation Wayne, looks like you drew
email watch for a while. Maybe it's just becuase
you're keeping an eye on the firmware release, but
refreshing to see the firmware programmer the CEOs
watching the list. ;-)

Using a Drake MS4 here (4 ohms), gives good punch on
CW, good fidelity on phone modes. 

Love the new K3 firmware!

We're working on all of these, Mike, along with the
DVR and additional 
subreceiver-related firmware.

I assume you're referring to SSB mode. Even though the
WIDTH control 
went to 6 kHz in SSB modes before, the DSP was
actually restricting the 
RX bandwidth to about 4 kHz. We'll revisit the
possibility of extending 
the upper passband in the future.

In AM modes, the WIDTH control now shows the *I.F.*
DSP bandwidth (up 
to 10 kHz), reflecting an AM RX passband that extends
up to about 5 
kHz.

Hz?

We actually do process signals down to this level, but
further 
improvement is possible. It's on "the list."
