[Elecraft] Simultaneous audio out digital out for K2 -- safe?

With my Alinco DX-70TH, I have become used to using the waterfall spectrum display to zero-beat CW signals. Just spin the tuning knob until the signal is sitting on the beat frequency, and you're tuned. I also like to use my ears to get a rough find on PSK and other digital signals. Both

Re: [Elecraft] Xtal Socket - a bit off topic

And if you take two FT-243 xtals and tape them upside down and back to back you can electrically switch between two crystals at a time and flip them over mechanically for a total of 4 frequencies (if there is headroom for the pins that will be sticking above the top of the crystal that is

RE: [Elecraft] Simultaneous audio out digital out for K2 -- safe?

Cathy, I don't know how much your soundcard would load down the speaker line (I would tend to believe not much), but you certainly should not hurt anything, so give it a try. If you want a separate audio output line for the soundcard, take a look at the K2 Fixed Audio Output article on my

Re: [Elecraft] Simultaneous audio out digital out for K2 -- safe?

I use a Y cable plugged into the headphone jack. Worth a try. 73 de NA8M John Both are these are very easy with that setup because I get audio out of the speaker *and* audio into the sound card at the same time. The K2 cuts off the speaker when I insert the cable into the ext speaker jack,

RE: [Elecraft] Trouble with PLL Cal K2 #5061

Pat, The frequency is the problem - the microprocessor is waiting to see a frequency near 12100 kHz. Go back and check the PLL range to see if the frequency is correct at the high end of the range. If PLL high is OK, then look carefully at the capacitors in the VFO Range Select area are correct

[Elecraft] Wider IF modification for SSB

I found a whitepaper written by K16WX that discusses various modifications to the K2 to widen the IF. I do a lot of digital mode operations. Widening the the IF would let me scan through a wider AF window. I have a very recent K2, complete just last month. If I understand the document, I

RE: [Elecraft] Wider IF modification for SSB

Rich, The 2.3 kHz wide filter that is detailed in that paper has since been incorporated into the KSB2, but is referred to as a 2.4 kHz filter (now the 'stock' width - the difference can be found in the measurement of filter width - John, KI6WX measured at -3dB and Elecraft measures at -6dB.

[Elecraft] Simultaneous audio out digital out for K2 -- safe?

Hi Cathy, I take the audio from the K2 headphone jack and feed it directly to the line-in jack on my sound card. By un-checking the Mute box on the soundcard control for line-in, I can hear the K2 on the computer speakers. Adjust the volume with the line-in slider and/or the volume control on

Re: [Elecraft] Solder?

Solder is a very subjective thing. The thing to do with any solder unfamiliar to you is use it on some cables, components, connectors and evaluate the quality of joints it makes with your soldering tools, skill, etc. You can see if it takes more or less heat than old solder you are familiar

Re: [Elecraft] Solder?

Thanks Stuart, After using the solder from Circuit Specialists for awhile on some test parts, I decided to trash it and just ordered some Kester 285. I'm confident I won't be disappointed. Thank you to all on the list for giving me good advice on this issue. 73, Spence W7CSW

[Elecraft] What a night

After I got home from dinner I worked my CW mentor for about an hour on 40 meters with my K2/100. That was fun. Then I got back to my NC2030 and got another stage debugged and working as per directions. Then I got on the computer and banged out a bit more of the Barnes-Hut algorithm I am
