Re: K4 Features and current K3+

I can not use the digital modes because I need to switch to Upper SB after the last
electron has been sent in the digital mode and the reverse. Call is instant break in
between USB voice and digital M110 A
This could be a deal breaker on a K4 purchase.

Re: K4 Features and current K3+

Jag försökte kasta om GPIO_IN_LOW="gpio18" till GPIO_IN_HIGH="gpio18"
men det blev ingen skillnad så det verka inte vara svxlik som bråkar.

Å andra sidan är spänningarna rätt...

Re: K4 Features and current K3+

In reply to this post by Ralph S

I don't understand the problem. When the K3 is set for Digital A, it
sets USB and uses the Line Input. To switch from LSB to a digital mode,
all you need is to change the Mode (the rocker switch). Elecraft radios
can be set to remember settings by Mode, so when you switch, you return
to your last used settings. I use VOX for all digital modes and voice,
which further simplifies things.
