Hi, thanks for the hints and information. I will listen to the signal once with my K3. That seems to be the best way to check the hint. But I will also have a look at the connector plugs and power supply cables in my portable configuration. 73, Wolfgang DL2KI -- Sent from: http://elecraft.36

If you are getting an ERR PTT when you power on, then either the key (Paddle) is closed or the PTT in the microphone is stuck in the active position. Remove the hand key, paddles, any PTT switch or footswitch and microphone to see if the Error goes away. If things are then OK, plug each one

Re: [Elecraft] [K2] Interfacing a DTMF Pad

Phil, The only problem with a simple Y connection is that the mic will be 'live' when using the DTMF pad. If you need an attenuator, try a 100k in series with the cable and a 10k from the line to ground. Those values are high enough not to interfere with the mic. Adjust the value of the 100k

I don't have any experience with chirps, but I can add this bit. If you can hear the change, then the change can be seen on an FFT. At least that would give a sense of whether the shift is up or down, if it is difficult to tell by listening. An FFT could also be applied to the RF, but, as Victor

Generally a chirp would be due to an unstable power supply, resistance in the fuse holder, etc.. It can also be cause by poor decoupling/loading of the oscillator circuit, but in the case of a well-designed circuit like the K2, this would normally only arise with misplaced components or poor conne

A chirp can't be seen visually on an oscilloscope (well, maybe on a panadpter or spectrum analyzer if it is a very big one). A chirp is a change in frequency of the transmitted signal. It is not the same as a click, which is a wide signal caused by too-short rise and fall times of the keyed en
