Computer Boot Up Keys the K3S

[Irwin KD3TB]

When I boot up my computer it keys the K3s Radio. I seem to remember there
is a setting in the K3s Radio to prevent this?

Ahhh yes.  I had a similar problem very recently and the list solved it
for me.  I'll pass it on ...

Hold MENU for CONFIG
VFOB to PTT_KEY
VFOA to OFF-OFF
MENU

I think CONFIG-->TECH MD must be on.

If you use RTS and/or DTR to key your rig from a computer, you'll have
to set these back where they belong.

Yep, boot the computer before you turn on the radio.

Hi Irwin,

Here is the poop from firmware
MCU 5.33 / DSP 2.86 / FPF 1.23, 8-3-2015

* DIVERSITY WORKS WITH MISMATCHED MAIN/SUB RX FILTERS:  Diversity mode in the K3S (or a K3 with the KSYN3A installed) now works with any combination of main/sub RX crystal filters. They can have different bandwidths or offsets, and it's not necessary to have an equal number of filters in each receiver. Note: Matched filters are optimal for diversity, but non-matched filters will still perform well.

* PTT/KEY USE WITH THE USB PORT IMPROVED:  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. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on 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 PTT-KEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S.

* CANCELLING UNEXPECTED PTT-KEY ACTIVATION:  If an external source (usually a PC) activates PTT or KEY unexpectedly, you can cancel transmit by tapping the XMIT switch. This will show ERR KEY or ERR PTT on VFO B. Once the PTT or KEY source as been removed, transmit will be re-enabled. If the cause may be unneeded PTT-KEY activation via the USB port, go into the CONFIG:PTT-KEY menu entry and set the parameter to OFF-OFF.

Cheers,

Fred KE7X

Do you have it on vox mode, and perhaps the K3S sound card is set to default sound device  (and windows startup sound is triggering the Vox)?

 nothing new here  My K3 does this as well

the computers serial port will toggle the DTR and RTS several times
during the boot process.   some computers more or less.   My laptop
will hold it on until I launch  a program that accesses the port like
VSPE or a logging program.

the solution.  you could disable keying from the RTS or DTR in the
menues  but if you are using that to say send CW from your computer
that is a poor option.

My solution is this.  I either turn off the K3 when the computer boots
or hold the TX TEST  to disable transmit. untill the computer has
completed the boot.

See the firmware release notes.  There is a setting to help with this.
