For those folks using the Meinberg NTP app, there's an associated nice little utility called NTP Time Server Monitor that's also downloadable from the Meinberg website.
Its GUI shows all the details about the NTP servers in glorious colour so it's easy to see at a glance which ones are being used by the NTP client on the PC, and there's also the useful facility for showing in graphical form the PC clock's offset from 'real time' over a period of time which makes it very easy to see exactly how the PC's clock has drifted and been adjusted by the app. -- Martin G0HDB |

Re: #mainscreen Strongest Signal Possible
#mainscreen
It's a tricky one, Steve, I have a neighbour who uses 145MHz FM and, if we both try to use the same mode within a few kHz or so of each other, we interfere with each other. We are, probably, within the near field of each others antennas... Most, or even many, receivers that are used in the Amateur bands are not very good at rejecting strong signals that are very close to our own frequency. You only have to look at the IP3 performance figures, and even then the claimed performance levels are well outside what we all regularly have to put up with within the Amateur bands. So, your neighbour could be transmitting a signal inside the required transmitter limits, and your receiver is receiving inside the claimed IP3 limits, but in your real world your receiver is being overloaded by your neighbours transmitted signal. Transmitting the wrong grid is not, at least here in the UK, an offense against the regulations, so I doubt that the Canadian authorities will be very interested in investigating your neighbour for a wrong grid transmission. At times I see signals that I think are reflected by aircraft scatter, but they always tend to slope to the left or the right. Occasionally I see a signal with multiple images that do not move in frequency, these are sometimes stations with many 'wall-warts' plugged into multi-way sockets that input multiples of 50Hz (or 60Hz if you live in a country with that mains frequency) from the main signal. Try telling those people that they are transmitting multiple images across the band and see how far you get... Dave (G0DJA) |

The other day, I decoded a fellow @ +60dB ! I have two guys within 3 lies who regularly hit me with +25-28... The irony is that the +60dB guy was about 350 miles away. Turns out, he forgot to turn off his auto-band-changing, auto-tuning 1200 Watt linear from working SSB an hour earlier. I will say this, he had a really clean output! Wasn't splattering, just solid red. As for the wrong grid, I see a lot these folks that get in a hurry & fat-finger the keyboard. It's pretty funny to see folks who's QRZ page says they live on land, who's grid tracker report pops them up in the middle of the ocean; and not on a boat. Unfortunately, some don't provide an email address & you can't tell them. I wonder out loud here... how hard would it be to add 3 bits in order to warn of: clock(DT) too far off; grid not right; or QSY because they are getting hammered by another station... 73 - John - N7GHZ What is the strongest signal possible to receive on the Band Activity Window? I have a very close neighbor who refuses to answer messages and emails but his signal strength I saw today was a +28. I have tried notching him out but he still squeaks through with a +4 or 5 even notched. First time I ever saw AGC kicking in on FT8. |

As others have said, Meinburg is very good. I closed down my D4 and swapped over to NTP time settings. I can run the Meinburg software to keep track of what is happening, but if you follow the instructions at https://www.satsignal.eu/ntp/setup.html and then use the "CMD" line (press the Windows button and the letter "R" and press enter and at the prompt that comes up type "ntpq -pn" (make sure you put the space in between 'ntpq' and '-pn'...) and you should see something like this come up in a DOS window. C:\Users\Owner>ntpq -pn That tells you that your PC is now getting its time signal from the ntp servers and you can forget D4 or finding that your PC is driffting in time. Cheers - Dave (G0DJA) |

Not sure what else to do short of reporting since he is actually transmitting wrong grid. Not sure what his "game" or "intent" is? Steve VA3FLF |

Re: Receive reports??
Guys, In this case the OP has a IC-7300 where the ADC is in the RF chain. This radio has a check that the ADC is not being overdriven. If it is the RF gain should be lowered to prevent it. Hence why I suggested to apply the maximum RF gain that didn't overdrive the ADC and then control the overall gain using the two digital controls. 73 Phil GM3ZZA On 15 Mar 2021 16:56, Bill Somerville <g4wjs@...> wrote:

Actually you want to adjust the *ANALOG* audio level in the 7300.By “RF gain” being turned all of the way down I am assuming that you are using the controls on the 7300. If you are on a Windows computer, go into your sound settings, advanced tab. Select Microphone/USB audio codec. Right click on the icon to get into properties/levels and reduce the value there. You might want to center the RF/squelch control first. Reduce the level until the WSJTX incoming signal bar is where you want it.Hi Joel, In Windows Control Panel -> Recording -> Microphone (USB AUDIO CODEC) -> Levels right click on the slider and select (check) decibels. Now adjust the slider for 0 dB (or as close as possible without exceeding 0 dB). Now *in the IC-7300* Use SET MODE -> CONNECTORS -> ACC/USB AF Output Level to adjust the WSJTX "audio meter" to 30 - 40 dB with your antenna connect, RF gain at maximum, and the IC7300 tuned to a frequency with no signals (typically just above the "JTModes" frequencies, e.g. 14,084, 21084, etc. during the week). By adjusting ACC/USB AF Output with RF gain at maximum an no signals, you can use the RF Gain/attenuator to reduce the audio levels when there are very strong signals present. Reducing RF gain will reduce sensitivity to weak signals but they will probably not be able to be decoded anyway with strong signals due to overload of the DSP in the rig. 73, ... Joe, W4TV |

Re: Rigblaster Blue doesn't modulate/CW/RTTY/WSJT-X my Kenwood TS-2000X

Don, As I explained that I made an interface cable that connects directly to the ACCY jack instead of the mic jack. This then made it possible to regain the use of the mic jack. In a TS2K(X) setup there are four links of the TX audio chain, the Pwr slider in WSJT-X, the Sound Speakers slider, the TX audio pot on the Blaster and the level input setting in the TS2K(X) (menu 50B) when using the Rigblaster. A setting of 0 on menu 50B means no TX audio at this point. If the TX audio pot on the Blaster is fully CCW then no TX audio. At this point I do not know which would be better for this guy, the Blaster setup or something like a IC7300 with built-in CAT and audio CODEC. I can get him up and running on both setups. I have a black and white tutorial for getting WSJT-X to a IC7300 up and running in short order time. The reason for the adapter cable is that the mic gain setting could not be touched because it was one link in the WSJT-X TX audio chain. I use Icoms now for the reason of only needing one cable. I never tried the headphone jack on the Blaster, I used the TX MONI at the TS2K. Bruce N7XGR On Sun, Mar 14, 2021 at 10:30 PM Don Roden <donroden@...> wrote:

Re: IC-7300 rf output only on WSJT-X Tune

Checked on both my HF and 4M setups, hit tune and send a carrier, hit tune again go back to RX, enable TX and it transmits CQ or whatever msg is selected, no problems, strange it seems as though its only the IC-9700 setup which is affected ? Derek G8ECI

Hi All, I have had the same thing happen since I upgraded to the latest general release, I have three separate systems here, radios and PC's, it certainly does on my IC-9700 setup, will see if the HF 7610 and PC does it, as well as the 4M IC756, transverter and PC does it, all PC's are running WIN10, I thing with the latest updates, and the latest WSJT-X general release. All use HRD for logging (networked to log to on server the 7610 PC, i7 Processor & 16G Ram) with JTAlert as well. Will check this afternoon on the two other systems and report back. 73 Derek G8ECI

Re: Receive reports??

Thanks Phil. I'll go looking for those settings in the radio, but might have achieved something similar by following other advice to use Windows Advanced sound settings to reduce the Icom-supplied USB driver's output.
Coincidentally or not, the right setting there was also about one third of the available range, like your settings. |

Re: Receive reports??
wsjtx@...
Thanks Joel... that has addressed the issue with the receive thermometer nearly always being in the red.
You are correct, I was turning down the 7300's RF gain control to try to hold the thermometer down but having only marginal effect even when RF Gain was turned all the way down. Following your advice I dragged the slider back to just 30 - it was at 100 - and now even with the RF Gain set to full/normal I'm getting a green thermometer in the 70-75 range. Might this change reduce the disparity between my receive reports and the other guys'? We'll see soon. Thx again. For someone else who may read this later, Windows would not at first allow me to adjust the slider for WSJT-X. Once I rolled back WSJT-X's power to zero and hit the Tune button, the Windows Advanced sound settings window allowed me to adjust the slider even after I stopped tuning/transmitting. |

Re: Receive reports??

Thanks. Yes, msg #13890 advice has been followed. I'm using a USB interface rather than my computer's sound card (Icom 7300 to Icom-supplied USB driver on the computer). Following the #13890 advice the devices is at zero db when the slider is all the way to the right, as the advice says may be the case in some systems. It seems to be calibrated properly per those instructions.

Re: Receive reports??
wsjtx@...
Thanks, but it seems that my experience is the opposite of what you're speculating. Other stations are reporting me as if *I* was running QRO but I'm not - I'm usually running 22 watts off a wire dipole, 30% of the IC-7300's power. However the other stations often give me a MUCH higher signal report than I give them, so whether they're running QRO or not it's me and my wee chirping that is reported to be blowing them out of the water.
I've started to conclude that many operators are offended by that because I get a WHOLE lot of exchanges that end without completion after I report my (usually much lower) received signal report to them. |
