Dwight, Is this a K3/K3S when QSYing between modes? Do you have "Restore Filter Group on mode change" checked in Commander -> Config -> Filter Groups? 73, ... Joe, W4TV

What radio, Dwight? Lots of radios remember the settings per band. So, if you had a filter set narrow for a contest, the next time you QSY to that band, it would be narrow. If it is a radio

In Commander, how does one keep the Wide filter on when qsy'g? thank you 73 Dwight NS9I

JT9 (and JT65) are "updated" in WSJT-X improved. Updating seems to be primarily the automation of exchanges by the software. JT9 hears down to around -29. See:

I totally agree with you. I do not consider DXLab or for that matter , ay other application to be at fault. It is fairly obvious that it is RFI. I am trying what I can to eliminate it. Eventually I

Amidon doesn't make anything, they are a vendor selling stuff they don't know anything about. Fair-Rite is the manufacturer nearly all ferrite cores that are useful to hams, and they are the inventor

My designs are effective ONLY for insertion in MATCHED transmission lines in the range of 50-100 ohms. Any non-tunable device I know of that does anything useful is likely to fry in a poorly matched

Study and implement what's shown in the slides for my tutorial talk on grounding and bonding. You'll be chasing your tail until you do. http://k9yc.com/GroundingAndAudio.pdf 73, Jim K9YC

The *FIRST PLACE* for any common mode choke is at the feedpoint of the antenna. You want to minimize any RF on the outside of the feedline so it doesn't couple to any adjacent

TU VY much Joe and Gil! 73!

hello, I've also had heavy RFI problems in the past transmitting with high power, that caused the rotor interface (or maybe the USB port to which it was connected) to regularly crash and DXView to

+ AA6YQ comments below + As I explained the last time you brought this up, Gil, there is no practical way to determine exactly why WinWarbler fails when your RFI exceeds a certain value. Clearly your

There is only 1 WinWarbler until and unless I transmit on 20 Meters with > 300 W or so of output. With the TS590-SG or any other basic transceiver I have ever used I do not and never have had any RFI

I agree with Joe about coax chokes and getting the ladderline outside the house. I am wondering why there are TWO Winwarbler programs running at the same time? Gerry, WA9GON [email protected]>

Even if you go to a rooftop vertical (e.g. R-6000 or similar), install a high quality common mode choke ("line isolator") right at the antenna. The commercial antennas do not have sufficient

I have done the required calculations and meet the requirements. Nevertheless I tend to agree that it is the direct exposure you refer to. Come nicer weather I may switch to a different antenna that

ohhhhh, that would be a good one! I'd vote for that too. LOL 73,

If your problem is not uncontrolled common mode RFI, it is direct RF Exposure. If direct RF Exposure is causing your problems, you are probably in violation of part 97.13 (c). Have you

I’m still waiting for the “enable coffee pot on rare DX” interface ? 73, Ken, KJ9B Sent: Tuesday, March 4, 2025 9:30 AM To: [email protected] Subject: Re: [DXLab] Band spread One

One more question....is there anything your software won't do? :) take care 73,
