[Elecraft] WSJT-X and K3S ALC

While mentioned earlier, the effort to set the correct audio level such that the ALC bargraph shows 4 bars solid and the 5th bar blinking has been a challenge to many.  I noted today that did happen after I changed a few things around at my station.  Further investigation concluded that the

Re: [Elecraft] [P3] P3TXMon Wattage/SWR

I suggest that you label the ends with extra labels close to the SO-239 jacks with "in" and "out" or something else meaningful to you before opening the box. A labeler does a nice job, but a Sharpie marker will be effective as well. 73, Don W3FPR On 8/27/2017 6:56 PM, Nr4c wrote: I

Re: [Elecraft] [K3] Notch filter vs JT65?

I agree with Jim, very strong signals will wash out a waterfall but have very little effect on decodes.  I have decoded extremely weak signals only a fewHz away from strong signals.  I leave filters at 2700hz and NEVER use anotch filter on any WSJT modes.  73, Dave N4DB On Sunday, August 27,

Re: [Elecraft] [K3] Notch filter vs JT65?

All very good advice. BUT - how close is he?  How much bandwidth is he occupying?  How many dB down at how many Hz from the center of his signal? AND VERY important -- K1JT has repeatedly advised to NOT to any filtering ahead of WSJT-X, because the phase shift associated with the filter

[Elecraft] OT - Notch filter vs JT65?

And he may be running a linear amplifier which is not tuned correctly.   I find frequently that hams really do not know how to tune a linear amplifier and operate it so it is "linear".  The result is splatter among other artifacts.    As they say, there's more that 's wrong than correct. 73

Re: [Elecraft] [K3] Notch filter vs JT65?

A couple of things to check. Be sure the Line Output from the radio is not set to high such that it is driven into distortion. Also check the computer CODEC gain isn't too high and it being driven into distortion. This is set in Windows Sound device Recording Level. Also make sure the ALC

Re: [Elecraft] [K3] Notch filter vs JT65?

He's really close - 2 miles. At that distance, any power would wipe out JT65. I'm venturing to guess it's DSP artifacts. The humps are too smooth and asymmetric to either side of the notch in the spectrum display. On Sun, Aug 27, 2017 at 8:00 AM, GRANT YOUNGMAN wrote: >

Re: [Elecraft] [P3] P3TXMon Wattage/SWR

The currently-shipping sensors are the same for the W2 and P3 TXMON. If you have an older W2 sensor (I'm not sure of the S/N cutoff date), it will work, but the bandwidth may be limited on the waveform display. It can be modified by changing several capacitors. I don't see modification

Re: [Elecraft] [K3] Notch filter vs JT65?

Rather than blame the K3, your sound card or “artifacts”, I’m going to stick my neck out and suggest he’s one of those guys that thinks everything works better when you crank the gain all the up … How far away from you is he? > On Aug 27, 2017, at 10:41 AM, Don Putnick

There's a local ham who is also on JT65. He shows up as a big red splatter on the waterfall. I used the K3's notch filter to remove him. He's gone but now there's big red splatter to either side of the notch on the waterfall and two wide peaks on the spectrum. K3, iMic soundcard, or JT65 signal

Bret, Yes, get a 2nd P3TXMON and get a switch to change the RJ-45 cable between the two sensors. The switch will likely be a manual one. 73, Don W3FPR On 8/27/2017 8:34 AM, MaverickNH wrote: And while I'm at it, is there a way to put a P3TXMON on both ANT1 and ANT2?

Yep - LOAD to Antenna. That's what I thought should be correct. So why I installed it backwards last August, I'll never know! I just reversed it. Numbers look spot on now. *And* I see the UPS I'm using appears to limit output if I exceed the power draw specification. I just installed the software
