Yes, this is available in general aviation by audio panels like the Garman 350c which offers what they call 3D audio. That allows you to set up different sources to appear to come from different locations or seats in the cabin. PS Engineering offers something in the PDA 360EX called IntelliAudio,

Re: [Elecraft] EFHW

On occasion I've run into RF in my KX3 when using a coax to feed random length antenna. The symptom was that the radio wouldn't transmit with anything other than trivial power, even though the tuner matched easily. A quick choke wound out of the coax helped a little, but the Elecraft BL2 stopped

Re: [Elecraft] USB devices disabled?

Specifically the error means that something plugged into the USB ports of the computer is exceeding the amount of power it should be drawing. There could be several reasons, including a short in the USB cable or a device that doesn't follow the protocol for getting more power from the port.

Re: [Elecraft] kx3 receiver versus K3s receiver

I'm not sure why you would think this is a problem, the "other side" signal is removed by the I/Q decoding technique, not by filtering. The filters do the job of roofing filters, reducing and removing near in strong signals -- from the IF signal that just happens now to be at baseband frequencies.

Re: [Elecraft] P3 "USB DEVICE REMOVED"

Re: [Elecraft] Sync AM and checking VFO accuracy using WWV

Depending on why you want the accuracy, I think you could improve things by building a phase comparator to "listen" to the radio output frequency against a local reference. That would allow you to get much closer than using your ears as a phase detector. That should get you accuracy of a few % of

That is a great idea Niel. The platform is getting used so much for all manner of things that used to need a "real computer" that it is a shame that it is not a first-class device. We can have a bunch of people "in-line" so that Elecraft doesn't run the risk of the guy leaving. A couple of NDAs,

Re: [Elecraft] Soon to be an Elecraft(er)!

Given my understanding of the roofing filter design in the KX3, I don't think there is any per-band adjustments to make. IIRC, the filter is an analog low-pass filter that operates after the direct down-conversion. If I'm wrong, then please set me straight. Especially because I'm considering

Re: [Elecraft] WSPR & Diversity RX

Hi. I don't think you can simply combine the two outputs. Any phase differences in the signals coming out of the two receivers will result in added canceling and/or adding of the signals. I can see two ways to go: 1. Two sound cards and some software that either understands the diversity.
