Hi Fred, I realize I'm pretty late in the thread but... if you are willing to experiment, you can check out my blog post here: http://www.aerodynes.fr/2014/01/08/kx3-gnuradio-spectrum-visualisations/ This uses GNURadio to do really nice looking IQ spectrum visualizations with the KX3.

Fred, Seems like I recently saw a lightning T-splitter which might work announced (related to the new iPhone with no headphone jack), by Belkin I believe. I wonder if that might be a solution to charging in such a situation. OTOH -- my iPad Mini battery seems to last a very long time.

Fred, one of the Apple lightning to USB adapters also contains a female Lightning connector that allows for charging/powering along with the USB interface. It is called the “Lightning Digital AV Adapter” I believe. 73 - Mike - K9JRI > On Sep 15, 2016, at 10:40 AM, Fred Moore

Re: [Elecraft] KX3 SDR MAC

Fred, If you have the PigRemote it will serve as the RS-232 connection from iSdr to the KX3. If you do not then then just set the frequency on iSdr to 0 (zero) kHz and the frequency you are tuned to will be at center screen and other signals will be displayed as plus or minus kHz. It works

Fred, what is your goal? The KX3 does not require any SDR software. Panadapter, try iSDR on the iPad. If you have a PigRemote it will even display the KX3's frequency. It connects to the I/Q jacks. Fill us in what functions you are looking for. Michael Blake k9...@mac.com > On Sep 14,

Re: [Elecraft] KX3 SDR

Did not mean to imply that the Raspbery Pi or BBB panadpater was anywhere close to the PX3, but that looking at the code could help with OP's original question. Built mine while waiting for PX3 and yes they are day and night re functionality and ease of use. I love my PX3 -- View this message

Re: [Elecraft] KX3 SDR

I built that one using a Raspberry Pi a couple of years ago, pre-PX3. Worked fine for what it is, but ergonomics are not even close to that of a PX3. 73, Phil W7OX On 7/28/16 4:58 AM, Bob N3MNT wrote: Also be aware that many PC's ( especially laptops) do not have stereo line -in jacks.

Sorry, I was thinking of the KX2 which always has the IF shift enabled. In a KX3, the center of the IQ stream is approximately the dial setting. I say approximately because some modes (AM, FM) or submodes (narrow SSB using Weaver demodulation) there may be some offset regardless of the

Re: [Elecraft] KX3 SDR

The signals at the IQ jack on the KX3 are analog, not digital. They are centered approximately 8 kHz away from the dial frequency as the KX3 uses an internal offset of 8 kHz. Depending on the firmware release and user settable options, that offset may be on either side of the center of the IQ

Hi Yes, well I have used those in the past, hence my confusion, when I see bandwith of a SDR at lets say 24Khz and I am sampling at 48Khz. Does that mean I am sampling the whole bandwith of 24Khz centered on freq X, or am I a sampling some point Y at +/- from the center frequency. I am trying to

Re: [Elecraft] KX3 SDR

If you are writing your own software, you will have to become proficient in Digital Signal Processing. The I and Q signals are simply baseband signals that are 90 degrees out of phase - by themselves, they will do nothing but audio signals, but with DSP processing, they can do most anything

Re: [Elecraft] [KX3] SDR transmitter issues?

Although it is not shown on the graph nor in the text, the ARRL report shows the noise in dBc/Hz, i.e. a bandwidth of 1 Hz. This must be adjusted to the appropriate bandwidth. Add 27 dB to get to 500 Hz and about 33 dB to get to a typical SSB bandwidth. And the worst noise is about -110
