Firing up K3 attached to PC via USB

When firing up my PC with K3s attached and on, the K3s trips into transmit a
couple of times. Is that normal?

Yes, it's normal. There is a config parameter you can set to eliminate
this behavior.

I can't think of it at the moment, but someone on this list will surely
remember what it is.

Yeah, unfortunately it is. It's Windoze checking out the serial port
connection. You can avoid the problem by setting CONFIG:PTT/KEY to
OFF/OFF. I have one of the PF keys programmed to access that menu item
so I can set it up on the rare occasions I use computer keying (N1MM+).

No need to go into the Config menu. Put the 'Test' function on by holding
the Mode^ key. Start up the PC and no TX will occur.
Just don't forget to take the Test mode off again before calling that rare
DX - ask me how I know...

All,

The alternative is to switch on computer first, then your K3.

Of course you need to remember to do that, though ...

Go to CONFIG:PTT-KEY, tap the 1 key and set USB.SAFE.

Re: Firing up K3 attached to PC via USB

From the description of K3 firmware update dated 8-3-2015
MCU 5.33 / DSP 2.86 / FPF 1.23

PC applications can activate PTT and KEY at the K3S via the USB
port's RTS/DTR signals. However, initial setup of the rig's USB port
by the PC may cause pulsed or continuous activation of the transmitter.
This can happen if the computer is turned on after the K3S, or if the
USB cable is not connected.

The K3S now a "Safe" mode (the default) which disables PTT-KEY
transmit until the K3S receives a command via the USB port, such
as a read of the K3S VFO frequency.

To turn safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to
select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S
off/on.

Applications that use PTTKEY via USB but never send commands
to the K3S may require "UNSAFE" mode. In this case, unwanted
transmit can be avoided by turning the PC on before the K3S.
