I have a Ten Tec Hercules II amp I'm not using and I was thinking about trying it with my KX3.
I know the KX3 has a KEY OUT available on the ACC2 jack (I did purchase the ACC2 Module). From what I've read, Ten Tec amps will work with a non-Ten Tec transceiver without the full keying loop if there is a short delay (4-8 msec?) between the transceiver's KEY OUT closure and the application of RF. My question: Is there any delay built into the KX3 between KEY OUT closure and transmitting RF? I've read about the 8 msec+ adjustable TX Delay for the K3 but couldn't find any references to TX Delay and the KX3. I know there's a CW Delay setting in the KX3 menu, but that controls the time it takes the KX3 to switch back to receive after key-up. I'm not hoping for full QSK, but slow QSK/semi-break in would be nice. Thanks, John Pfeifer WL7M |

John,
In the absence of any other information, I would say that there is some delay between KeyOut going active and the onset of RF. I do not know the numbers, but in the K3 it is adjustable, and in the K2 it was between 12 and 15 ms. I expect the KX3 to be in that 12 to 15 ms range too. Validation of my guesses will have to come from more authoritative sources, but I can safely say there will be some delay in the onset of RF - I just don't know the numbers, but I believe your 4 to 8 ms will be within the "safe" region. 73, Don W3FPR On 11/27/2012 2:36 PM, WL7M wrote: > I have a Ten Tec Hercules II amp I'm not using and I was thinking about > trying it with my KX3. > > I know the KX3 has a KEY OUT available on the ACC2 jack (I did purchase the > ACC2 Module).
