[Elecraft] K3: Latest Beta FW - Vox, TX Gate and Notch observations in ss

[Luis V. Romero]

Yup, that's true, but I can show you my transmitted waveform and tell you
that I don’t extend very far from 2.3-2.6KHz wide ever...  My audio goes no
lower than 180Hz and no higher than 2750Hz if my former TV station's
Spectrum Analyzer is correctly calibrated.

But of course you're right!  Maybe these guys should get K3's?  <grin>

Lu -

One important thing to remember is that, while you're cranked down all nice
and narrow on RECEIVE, you're still transmitting through the 2.7 or 2.8 kHz
filters, so your TRANSMITTED bandwidth is quite a bit wider than your
RECEIVING bandwidth...
