[Elecraft] Macro for K3/K3s and FT8?

[Dave Cole (NK7Z)]

Hi,
I have a short blog post on adding an external control keypad to the K3 at:

http://nk7z.net/adding-external-keypad-k3/

About halfway down is a link to the CP48_Master-Spreadsheet, which is a 
spreadsheet where I keep about 20 macros.

There is also Fred Cady's  book, "Elecraft Macro Programming", which in 
addition to being the best reference on Elecraft macros, has a lot of 
finished examples.


73s and thanks,
Dave

But also want to go back to a 2.4 kHz bandwidth.  I might also want to transmit outside the parameters of my RX passband, e.g. in this example, I might transmit tones from 800-850 Hz.
