Re: [Elecraft] Interfacing Ke with MFJ929?

I use a SGC auto tuner in a similar configuration. Tuner at ground level, 40 feet of window line straight up to feed point of 130 foot doublet. TUN PWR on the K3 is set to about 5 watts in the menu. Press and hold the XMIT (Tune) button on the K3 and it tunes. On Sun, Nov 6, 2016 at 7:05 PM George

Re: [Elecraft] JT65 ON THE KX2

What??? That isn’t in any spec or manual for the KX2. Why 42 seconds? The KX2 manual says this, on page 27: "5.0 watts or lower is recommended in all data modes. The KX2 will reduce power, if necessary, to maintain a safe operating temperature.”

Re: [Elecraft] Interfacing Ke with MFJ929?

In CONFIG menu, TUN PWR defaults to NOR, where tuning power follows the power knob. But TUN PWR can be pre-set to any other value, which it will produce whenever the "xmit" button is held. (I have mine set for 50 W since my SWR indicators are manual). You could use 5W or anything else. Is

Re: [Elecraft] JT65 ON THE KX2

Check manual for digital modes using DATA A submode. Watch power out as this mode has a 42 second 100% TX time. Sent from my iPhone ...nr4c. bill > On Nov 6, 2016, at 11:31 AM, Robert 'RC' Conley wrote: > > How is it accomplished? > > -- > May You Live Long and

Re: [Elecraft] Interfacing Ke with MFJ929?

I have a MFJ-927 which is probably the same circuit board in a different, water resistant box. It's powered over the coax with a bias-T. It's set up to automatically tune when it sees RF. I give it about 5 watts of "TUN PWR" and it finds a match, usually pretty easily. Sometimes it's. Little

[Elecraft] Interfacing Ke with MFJ929?

I wonder if anyone has interfaced a K3 with an MFJ-929, used as a remote tuner? One of my antennas is a doublet fed with 450 ohm ladder line. The ideal place for a tuner is at the base of the ladderline and I intend to experiment with a variety of baluns to see which work best on which bands.

[Elecraft] P3 - utility, a question

I have the latest version of the P3 utility as downloaded from the Elecraft website viz 1.16.3.15. I note that it enables the creation of only 16 macros (the P3 can store 50 macros), and furthermore those macros don't seem to be saved to the P3 itself (but clearly it is a useful way to test

Sri Jim: You must have misunderstood. You defined the rig as the 'load' so I used your definition. Perhaps that's the problem. Avoiding that terminology, if there is no reflected power at the rig, the SWR will be 1:1. Power can be "lost" in the antenna (hopefully radiated) or consumed in the

Re: [Elecraft] K3S USB audio questions

Hi, FWIW I've done this. I've increased the gain by 12 dB, i.e. two bits. Incidentally, the scaling on CONFIG:LIN OUT is linear - i.e. the output voltage is proportional to the number. So for +12 dB w.r.t. the default I've increased it from 10 to 40. Richard Lamont G4DYA On 06/11/16 16:48,

[Elecraft] KX2 alt MD

A small group of us in the Pacific NW operate voice and digimodes on the lower bands (40m, 80m) and we seem to be frequently shifting between voice and digimodes. It would be nice if a future firmware update removed the necessity of the alt MD feature and put the alternate mode access in the MODE

Re: [Elecraft] K3S USB audio questions

Hi, You make a good point for some digital modes. But you should be able to make up for most or all of these 3 bits by increasing the LINE OUT as it must surely be before the codec ADC but probably not before the K3's DSP DAC. It's a shame that they have to do it this way (back to back DAC/ADC,

Re: [Elecraft] TxMon and K3 (tuner bypassed) SWR missmatch

Line loss decreases the SWR measured at the source, not the load. In this case, thinking in terms of return loss makes this thought experiment easier. The line loss adds to the return loss of the load, increasing the input return loss by a factor of 2 X line loss (dB). Higher return loss =

Good Evening, The sun has been active this week. So active it made a lot of noise. However, after that calmed down signals were better than they had been in a while. DX kept popping up like the local chanterelles. While clearing out an acre of hillside I flushed a grouse. That is
