Re: [Elecraft] Specs KIO3-B internal sound card

Thanks Christopher, compared to high quality external devices SNR and THD+N is rather poor. And so is the dynamic range and the max. sampling rate of just 48KHz. Rather disappointing, to be honest. 73 Udo, DK5YA Am 20.09.2017 um 00:24 schrieb Christopher Hoover: The circuit is based on

[Elecraft] Specs KIO3-B internal sound card

Gentleman, I'm looking for specs of the internal sound device which is part of the KIO3B board but couldn't find any on the Elecraft web site. Anybody out there who's got detailed information? I.e.: Sample Rates Frequency Response Dynamic Range THD+N Noise EIN THD+N Outputs I'm just

[Elecraft] [K3s} VFO B Display Options

I seems I keep disabling my ability to display multiple types of information on rotation of VFO B on my K3S. I must be reading the manual wrong on how to enable as I can't seem to do it right. Help appreciated. Goes in my personal K3S FAQ index of things to remember that I forget! Bret/N4SRN

[Elecraft] [KPA1500] A/B antenna switch function

When the amplifier is *off* (from the front panel power control; mains AC on) what is the function of the A/B switch? Steve KZ1X __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net

[Elecraft] K3 VFO B display

I’ve recently noticed that when I when I switch bands on the K3, the VFO B display area briefly displays a small antenna symbol and the legend “KT500” next to it. I can’t find any reference to this behavior in the manuals and I’m curious. I don’t have the KAT500 (or KPA500) connected at

Re: [Elecraft] Sp3 a/b switch

Hi, Why would the amplifier be damaged from driving an open circuit? Transformerless solid state audio amplifiers typically are perfectly happy driving an open circuit. AB2TC - Knut Don Wilhelm wrote > Richard, > > If your K3 has all the audio amplifier mods installed, there should be > no

Re: [Elecraft] Sp3 a/b switch

Richard, If your K3 has all the audio amplifier mods installed, there should be no problem. If you have an early K3 without those mods, you could damage the speaker audio amplifier by driving it into an open or shorted load. Yes, the A/B switch will make the load to the K3 an open circuit

[Elecraft] Sp3 a/b switch

Hi I was wondering if there is a problem using the A/B switch on the SP3 as a on / off switch for audio from the k3. The k3 would be on. It seems like this would be ok but I am checking with the experts here. Thanks Richard __

Re: [Elecraft] Broken VFO B Encoder-menu access?

Many of the menu functions have program commands which address them, which can easily be typed into the command tester in the K3 Utility. Save the ones that you get working and need repeatedly in the Macro switches and assign them to K3 buttons. Once you get acquainted with that you might even far

Re: [Elecraft] Broken VFO B Encoder-menu access?

Chris, Yes, you can by creating Macros or by writing software to issue commands that will get you into the menu and change it. The K3/KX3 Programmers Reference can tell you how to do it. I do not recall that anyone has written software to do all of that, but there are some which do bits and

Hi Chris, You didn't mention which Elecraft product you're using. Check the Programmer's Reference for your product in order to see whether the menu parameter(s) in question can be set using a remote-control command (e.g., MN / MP). You should be able to execute the remote-control command from

I hardly dare to ask this question, but is there a way to access into the menu and change settings which is normally done by using VFO B. It will take 2-3 weeks until I get a replacement part. 73,Chris-OE5CSP -- View this message in context:

Re: [Elecraft] KX3 VFO B skipping

Tim, Sorry, but I do not have that information. You can get the replacements from Elecraft parts, but as far as alternatives (detented encoders), I have no idea. Since the controls are encoders rather than potentiometers, I think using something detented would not be the best thing. The

Re: [Elecraft] KX3 VFO B skipping

Hi Don, Do you have a manufacturer/part number for the encoders used in the KX3? That information doesn’t appear to be in the schematics. Based on personal preference, I’d like to replace at least some of the encoders in my unit with alternatives that that have detents as well as less

Re: [Elecraft] KX3 VFO B skipping

It is most likely that the encoder must be replaced to correct that behavior. The VFO B encoder is a thru-hole part and can be replaced if you have good de-soldering tools and work very carefully so you do not damage anything else around it or damage the board or the SMD parts that are in
