some have asked about the timing of the onset of carrier (rather than full power output) and the rise time of the carrier after release of TxInh. There is a bit of jitter in the onset of carrier that changes the onset from about 2.5 ms to 4 ms. Rise time to 100% is about 5 ms. (wish I had one

; Elecraft@mailman.qth.net Subject: Re: [Elecraft] txinh timing?? Measured Thank you Mark. I was looking for this information. Well.. it is very slow indeed. I thought it is much faster. Could you possibly measure how long does it take for the signal to appear at the output after TX Inh set to low? 73

I've looked but can't find the spec on how long after after initiating TXINH is the K3 transmitter at zero power? (I'm working on an so2r interface which can take away an antenna from the low priority rig even if it was transmitting. ) It looks like the TXINH is a polled input and may be a bit
