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.

I seem to remember there is a setting in the K3s Radio to prevent this?
