Make sure the KPA3A is enabled in the CONFIG menu. 73, Brian, K0DTJ __ 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

Re: [Elecraft] Fldigi and K3S

The K3S sound card should show up as a USB CODEC. In FLDIGI under Configure: Soundcard menu select the Audio tab and then Devices. Check PortAudio and make sure both Capture and Playback show USB Audio Codec. I use VOX to trigger transmit and have found I have turn the VOX Gain up from its SSB

Oops, that should have been Line OUT gain. Brian, K0DTJ On 4/16/2017 18:19, Brian Hunt wrote: Don't see a problem with making minor adjustments of the Line In gain during the first transmission. When I adjust the level using the WSJT TUNE button I usually see the wild fluctuations mentioned

Re: [Elecraft] K3 on JT-65, ALC varies widely

Don't see a problem with making minor adjustments of the Line In gain during the first transmission. When I adjust the level using the WSJT TUNE button I usually see the wild fluctuations mentioned. A small "tweak" to the gain will set right. 73, Brian, K0DTJ

Re: [Elecraft] CW net

Marv - Sorry you couldn't hear the net tonight. There were two QNIs: myself and Dale, K6PJV, both from near San Francisco. You are probably too close to the NCS in OR but if you can hear either of us, we can relay you in. Maybe some day condx will improve. 73, Brian, K0DTJ > On Apr 23, 2017,

Re: [Elecraft] fw upgrade

You want the latest production release. All previous changes are included in the latest version. Be sure to load all parts of the update: MCU, FP, and DSP. They all work together. You must also do a TX Gain Cal after the update. GL! Brian, K0DTJ

Re: [Elecraft] [K3] AGC White Paper

I noticed that your AGC curves were made with the RF gain full max. I rarely operate that way. I usually turn the RF gain down to where the noise peaks are barely kicking the S-meter. By doing so, is it fair to say I'm moving the curve to the right? I.e, a higher signal amplitude before the

Re: [Elecraft] Question about my KX2

Most 9:1 designs are UNUNs - unbalanced to unbalanced. For feeding a window line fed doublet, you definitely want a BALUN - balanced to unbalanced. The doublet / window line is a balanced system. The output connector on the KX2 is unbalanced. If you are using an UNUN in this setup you you may

Re: [Elecraft] Missing first piece of dash or dot when sending CW with K3S USB input with Wintest.

It's possible that Windows 10 is powering down the hub that the device is connected to. In the Windows 10 Settings dialog click on devices and scroll all the way down to the bottom and select Device Manager. Then click on USB controllers to open and view all the hubs. Double click on each

Re: [Elecraft] Elecraft@mailman.qth.net

Is the RF gain all the way up (-0)? Preamp ON? Is the CWT cursor blinking with the received CW? Make sure the filter is centered on the PITCH tone (indicated by the *. Use the SPT to tune the signal. Just a few thoughts. Hope it helps. 73, Brian, K0DTJ > On Jul 17, 2017, at 08:38, Tom

Re: [Elecraft] K3 Speaker question

Hi Gene, Your reply below begs the question: How do you have the Bose speakers hooked up? The manual page 20 (Rev D6) says when you plug in external speakers it cuts off the internal speaker. They are referring to the SPKRS 3.5mm jack on the rear of the K3. If the Bose speakers are using

Re: [Elecraft] K3 P3 and KAT500

As far as I know ARES members only operate within the amateur band allocations. Your K3 should cover what you need as is. Maybe you are thinking about MARS - Military Affiliate Radio System who do operate outside of the amateur band allocations. For that you will need the radio software mod

Re: [Elecraft] K3: Odd ALC behavior

I spent some quality time with my K3, FLDIGI and an oscilloscope today. I had the same problem as described. Looking at my USB soundcard output to the K3, the amplitude of the audio from FLDIGI in TUNE mode was rock solid. Looking at the MON output from the K3, the level oscillated in time
