[Elecraft] K3 / P3 - RS232 ???

[Cady, Fred]

Hi Hank,
That is a standard problem with RS232 ports when they have not been powered up before the K3. One solution is to go into your CW WGHT menu and tap the 4 key to select VOX AUTOOFF. This takes the K3 out of VOX mode when you turn the K3 off so when you turn it on again it can't be keyed, either by the internal keyer, the back panel KEY IN or the RTS/DTR signals (the culprits) in the RS232 interface. Then, after you power up the computer you can hold VOX to be able to send or transmit using VOX. The K3 will display VOX=OFF the first time you try to send without re-enabling VOX. I often program the power-on banner (using the K3 utility) to display VOX OFF.
Cheers and 73,
Fred
