[Elecraft] K2 / DSP

I have never had a K2 with a KDSP2 so I can’t make an informed comparison; but I can say that, having one in both of my K2s, the KAF2 makes the K2’s performance truly outstanding. As I understand it, having both was never possible – it was one or the other. Maybe someone can offer a

Re: [Elecraft] IMD and CW

Not in my experience as a broadcast engineer in the 1950's. Class C amplifiers, plate modulated, were the standard low distortion transmitters for decades, just as they were used in the best A.M. Ham rigs like the Johnson Kilowatt. But, as the big commercial stations came on the air running 50

Re: [Elecraft] IMD and CW

Re: [Elecraft] IMD and CW

I believe the K3/K3S use a raised sinusoid key shaping. It is a good compromise to reduce the bandwidth without excessive ringing/backwave. In the bad old days, CW key shaping was typically a simple R-C filter on the key line. That resulted in an exponential rise and fall, which resulted in

Re: [Elecraft] IMD and CW

The fact that the RF amplifier is running Class C should not be an issue if it is plate-modulated. Plate modulation is the "gold standard" because only the RF carrier is being amplified in the Class C stage. Beyond that its non-linearity is employed to mix the modulating signals with the RF

Re: [Elecraft] IMD and CW

Re: [Elecraft] K3 and WSJT-X 1.7

Is this when transmitting? If so, try setting Mode = "None" and Split Operation = "None" in the WSJT-X File -> Settings -> Radio tab. You may want to contact Elecraft Support to see if you can get access to the field test firmware (5.56). WSJT-X can (and often does) send the split or data

Re: [Elecraft] IMD and CW

Very interesting, Fred. It makes sense, though, that plate modulated class-C amplifiers aren't terribly linear. On the other hand, that kind of distortion probably doesn't affect WWV's mission. I wonder if the AM broadcast industry achieves lower distortion. Feedback comes to mind. 73,

Re: [Elecraft] IMD and CW

Not CW, and this probably won't work in 4X-land, but if you want to see the difference a Class-C amp makes, set your P3 span to about 6 KHz, and tune in WWV on its various frequencies. During the tone-on minutes, the 2.5 and 20 MHz signals will look as you expect an AM signal with a tone

Hi Mike, You can use the KY command to do that. Use the K3 Utility to program separate macros with: KY VE3WDM; KY 599 CA; KY TU; Write them to the K3. Then use the KPod buttons to send. You can't send an increasing number for a report although if you have a P3 with SVGA you could. 73,

For a CW signal, the nonlinearity of a typical power amplifier should have the effect of shortening the rise and fall times. That does indeed widen the transmitted bandwidth. But intuitively, it seems like the distortion would have to be really bad to shorten the rise/fall times by much.

Re: [Elecraft] KDSP2 discontinued??

Such things are probably doable, Kevin. But the market size issue is likely a major factor mitigating against such a development by Elecraft. If I were to build a second K2 after all these years, I'd sure want the KDSP2 in it; but that's not something I'm likely to do. My (partly) 17 year

You can connect the sdrplay to the IF out of the K3 and use Win4k3suite  or hdsdr to view the spectrum.  The Sdrplay would need to be tuned to 8.215MHz in HDSDR or it is tuned automatically in Win4k3.the SDRPLAY will provide 2mhz bandwidth in its most useful configuration but you can go to 8mhz
