Re: [Elecraft] KX3 RX I/Q testing
Thanks for the input I'm using the suggested iMic which does have a line input and a mic input. I'm beginning to believe that it really is that the radio is not working correctly. I'm going to reach out elecraft directly to see what I can do without sending the radio to them for the fact that I'm using it for my CWA class. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3 RX I/Q testing
iSDR does require a USB soundcard with a stereo mic input, like the Griffin. The easiest way to check if you are utilizing the stereo mic function in iSDR is to check your iPad screen while running it and see if you are getting 22 or 44 kHz. If it shows 22, you are only getting mono mic.

Re: [Elecraft] KX3 RX I/Q testing
Kevin, You are unlikely to hear anything from the headphones from that jack. Feed it into a soundcard and you should see something using a panadapter application like HDSDR or NaP3. The RX I/Q output is low level and broadband. It is not suitable for digital mode software like FlDigi. For that software, use the Phones jack. 73, Don W3FPR On 1/10/2019 12:24 AM, Kevin F. wrote: I did check that the RX I/Q was enabled and still hear nothing, on my computer, when plugged in to the RX I/Q port.

Re: [Elecraft] KX3 RX I/Q testing
The jack is 3/32 inch or 2.5 mm. Have you tried connecting the I/Q output to a computer and some SDR software that actually uses I/Q input? I don’t think you’ll hear much using phones. Scope should show the signal I would think. Be sure to push plug all the way into the hack. It is very stiff for the first several times.

Re: [Elecraft] KX3 RX I/Q testing
Kevin, The RX I/Q is at a low level, and is only usable for a panadapter like the KX3. It works for those applications because the signals are 90 degrees out of phase (which is what quadrature means). For Fldigi, and other soundcard data mode applications, use the Phones output to feed the soundcard Line In. 73, Don W3FPR On 1/5/2019 10:35 PM, Kevin F. wrote: Does anyone know how to test the RX I/Q signal is coming out of the radio correctly.

Re: [Elecraft] KX3 RX I/Q testing
The levels from the RX I/Q are very low, so you might not hear anything. Pages 26 and 27 in the manual talk about using that for computer-based SDR applications. Also, check the RX I/Q menu setting. If that is OFF, you won’t get any output from that jack. Finally, fldigi does not use I/Q signals for its waterfall. It uses the regular audio output from the PHONES jack. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jan 5, 2019, at 8:42 PM, Kevin F. wrote: > > Thanks for the prompt reply, I guess the question that I would like to answer > is, if I were to plug in to both sides of the RX I/Q port should I hear > anything at all?

Re: [Elecraft] KX3 RX I/Q testing
Kevin, The I/Q output is an analog two channel audio signal, but one of the signals is 90 degrees delayed from the other, hence in quadrature. If you plug the output of the I/Q port, one channel at a time into your computer mic input, you will hear a wideband audio signal. There will not be anything magic to hear. FLDIG wants the receiver's filtered audio to drive it. It develops what it needs from a mono audio input, either line or mic in. 73, Barry K3NDM -- Original Message -- From: "Kevin F."
