Bill,

 

It definitely looks like it helps to set the polling frequency higher. I have set it to 30 seconds. The problem then comes much more seldom.

When it does it is often immediately after I double click on a station to answer a CQ call and seconds before the RTS line and hence the transmitter is even activated. So it definitely has nothing to do with RFI.

Now any computer has a few mV of noise on the comport lines. In my case only the RTS line is even connected.

So if it is noise that occasionally  triggers it this means that HAMLIB and / or WSJ-X (due to the way it has been integrated) is polling the com line for a radio that is not configured and not connected.

So this is definitely a bug. When Radio: None has been configured there should be no polling

Can you mention this to the HAMLIB people perhaps, or should I? How do I eventually contact them?

I will now try and install a couple of 100 nF capacitors from pins 2 and 3 to pin 5. I see on the oscilloscope that this attenuates the noise present. Its only a few mV and this is way below the threshold on an RS232 line so it could be pulses occurring now and then due to some WIN thingy and 100 nF may not be enough so I am dubious that this will help. But I think it should not be this way anyway.

This morning everything started up without problems and has worked for some QSOs without failing.

But just now, a few minutes after finishing a QSO on FT8, the POPUP window appears.

Rig Error: Do you want to configure the radio interface?

On pressing Details: it says: HAMLIB error: IO error while opening connection to the rig.

Pressing retry and it goes back to working normally.

There is only one COM port (COM1) ant it is used for PTT with RTS.

No rig connected and in setup rig is set to none.

Nothing connected to any of the USB ports.

The WSJT-X is V2.2.2.

On the old computer I was running 2.2.0. Setup the same. Only one COM port and nothing else connected.

I never had this, or any other, problem while using this.

Maybe I need to roll back to 2.2.0.

I seam to remember having read similar reports with regard to HAMLIB on the reflector after the release of 2.2.2.

Is the old versions available on Princeton and any special precautions if rolling back?

 

Any other suggestions?

Hi Svein,

that sounds like RFI problems, does it only happen during QSOs on one band? Does reducing your transmitter power improve the situation?

As you say nothing is connected to your PC USB ports I assume this is a real serial port, you could try some ferrite clip on chokes at the PC end of the serial cable, or maybe just re-routing the serial cable to the rig. What interface are you using for the RTS to PTT switching, and where does it draw power from?

There are some videos on the net on how to use a USB GPS. (BktTimeSync has a built in way to read a serial GPS in Windows which I have not tested). I would not go that way because the USB dongles rarely have the Pulse Per Second output. So you get time that is output in serial somewhat randomly once per second, and you don't really know when the second ends, which is barely good enough for WSJTx. You could use it but it is so much better to use a serial GPS which has a PPS output. However a PC is not really set up to take the PPS signal. It is a very short pulse and Windows isn't set up to do real time pulse reception. I've done it with both Arduino and Raspberry Pi. The Raspberry Pi is the better choice because it has networking and WiFi and being Linux it can run all the standard software for NTP that has been written and tested for so long so there is no software to write. I did it with the Arduino and made it a USB peripheral (the FDLog Clock) but I had to write software for that, and the Raspberry Pi is much easier and better in many ways. There are quite a few articles on making a Raspberry Pi NTP server on the network. The Pi Zero W makes a great server and is very low cost. It works better than Windows and is easier. Contact me by direct email if you want to see part of the article I'm working on, it is pretty well along.

This shows two local GPS module based NTP servers running on a Raspberry Pi vs cloudflare. A Raspberry Pi Zero W at ten dollars plus a cheap GPS module with PPS makes a simple and inexpensive NTP server for your local network. The other server here is a Pi 3B+ which also has a web server causing it to have slightly more jitter some of the time. The display (below) is from the Meinberg NTP monitor on a laptop which currently shows  well under 1 millisecond of offset and under 7 milliseconds of delay via two wireless hops (the Pi's and Laptop are all on Wireless).

Hi Amos,

if you are referring to the Meinberg NTP Client then you will have a tool called Quick NTP Status on the Windows start menu (hit the WIndows key and start typing Quick until you see it). It lists the servers selected for synchronization, if one is locked it will be prefixed with a '*', it may take a few minutes to synchronize, and a day or so to get really good sync. The last but one column (offset) is the difference between your clock and the server's clock, in milliseconds.

However I can't open more than one client listening at port 2237. Perhaps this is normal? I've read about multicasting on this group but only in passing.

Is it normal to have only one listener on a UDP port? Or is it a function of my network stack? In my case it's System.Net.Sockets in the .NET framework.

73 de Steve N6VL
Hi Steve,

first let me say that I think you have misunderstood client and server in this relationship. WSJT-X is the client and your application is the server. These are rather loose terms with UDP networking but I tend to think of the application listening on the well known port (2237 in this case) as the server. As with all normal client-server relationships there can be many clients but normally only one server per IP address and service port pair. This is similar to web servers for example, a server may run at an address on a well known port (port 80 for web servers), and any number of clients can request pages from that server.

With the WSJT-X UDP Message Protocol the situation is the same, any number of WSJT-X instances can talk to the same server. Each WSJT-X instance will communicate using its own unique IP address and service port pair (probably 127.0.0.1 and an ephemeral port in your case).

The WSJT-X UDP Message Protocol is also designed to allow multiple *servers* to interoperate with one or more WSJT-X instances by using the same service port, this is enabled by using multicast UDP. To use multicast UDP each server must join a pre-arranged multicast group address, say 239.255.0.0 for example. Each WSJT-X instance is then configured to send traffic to that multicast group address rather than the address of a single server. With multicast each message sent to a group address is delivered to each and every server that has joined that group.

If there are multiple servers joining a multicast group *and* they are running on the same host, and binding to the same service port; then they must all set the SO_REUSEADDR socket option before binding the port otherwise they will block other applications binding to the same port. Note that this is not a multicast requirement, just one that is needed for multiple applications running on the same host to bind the same service port.

I think that those softwares use NEMA 0183 ’sentences’ for time synchronization, not 1 s pulses. In that case almost any GPS receiver is fine. Accuracy is still more than adequate for FT8 and FT4 purposes.

Does the BU have the accurate time signal of GPS? How come VisualGPS does not mention any specific hardware?

Amos, you seem to want good but simple. I use the GlobalSat BU-353-S4 GPS puck and VisualGPS NMeatime2 software. The software is FREE for 30 days & then $20.48US so you can try it out and see if you like it. The puck is about 30.00US from Amazon. Easy set up once. Never have to tough it again

There are some videos on the net on how to use a USB GPS. (BktTimeSync has a built in way to read a serial GPS in Windows which I have not tested). I would not go that way because the USB dongles rarely have the Pulse Per Second output. So you get time that is output in serial somewhat randomly once per second, and you don't really know when the second ends, which is barely good enough for WSJTx. You could use it but it is so much better to use a serial GPS which has a PPS output. However a PC is not really set up to take the PPS signal. It is a very short pulse and Windows isn't set up to do real time pulse reception. I've done it with both Arduino and Raspberry Pi. The Raspberry Pi is the better choice because it has networking and WiFi and being Linux it can run all the standard software for NTP that has been written and tested for so long so there is no software to write. I did it with the Arduino and made it a USB peripheral (the FDLog Clock) but I had to write software for that, and the Raspberry Pi is much easier and better in many ways. There are quite a few articles on making a Raspberry Pi NTP server on the network. The Pi Zero W makes a great server and is very low cost. It works better than Windows and is easier. Contact me by direct email if you want to see part of the article I'm working on, it is pretty well along.

This shows two local GPS module based NTP servers running on a Raspberry Pi vs cloudflare. A Raspberry Pi Zero W at ten dollars plus a cheap GPS module with PPS makes a simple and inexpensive NTP server for your local network. The other server here is a Pi 3B+ which also has a web server causing it to have slightly more jitter some of the time. The display (below) is from the Meinberg NTP monitor on a laptop which currently shows  well under 1 millisecond of offset and under 7 milliseconds of delay via two wireless hops (the Pi's and Laptop are all on Wireless). I'm working on an article showing how to set this up.

Hi Amos,

if you are referring to the Meinberg NTP Client then you will have a tool called Quick NTP Status on the Windows start menu (hit the WIndows key and start typing Quick until you see it). It lists the servers selected for synchronization, if one is locked it will be prefixed with a '*', it may take a few minutes to synchronize, and a day or so to get really good sync. The last but one column (offset) is the difference between your clock and the server's clock, in milliseconds.

BktTimeSynv by IZ2BKT is free and will connect to your GPS puck OR a time server if internet is available. . Mine syncs time on PC startup and when I start Log4OM logger. It will use GPS if the time server isn’t available.

I've finally been able get my code to talk to WSJT-X through the UDP interface both directions! I'm using the default port of 2237 in Settings > Reporting.

However I can't open more than one client listening at port 2237. Perhaps this is normal? I've read about multicasting on this group but only in passing.

Is it normal to have only one listener on a UDP port? Or is it a function of my network stack? In my case it's System.Net.Sockets in the .NET framework.

Just now I worked 8 JA on 20m with a full 1 KW without problem. Then on the 9th QSO it pops up again. So high power, low power same problem. 
So RFI it is not. 
I found the install file for v2.2.0 on my old computer so I will try that later today.
Higher polling seamed to help some as it took longer for the problem to appear, but this is way to inconclusive.

Rig Error: Do you want to configure the radio interface?

On pressing Details: it says: HAMLIB error: IO error while opening connection to the rig.

Pressing retry and it goes back to working normally.

There is only one COM port (COM1) ant it is used for PTT with RTS.

No rig connected and in setup rig is set to none.

Nothing connected to any of the USB ports.

The WSJT-X is V2.2.2.

On the old computer I was running 2.2.0. Setup the same. Only one COM port and nothing else connected.

I never had this, or any other, problem while using this.

Maybe I need to roll back to 2.2.0.

I seam to remember having read similar reports with regard to HAMLIB on the reflector after the release of 2.2.2.

Is the old versions available on Princeton and any special precautions if rolling back?

 

Any other suggestions?

Hi Svein,

that sounds like RFI problems, does it only happen during QSOs on one band? Does reducing your transmitter power improve the situation?

As you say nothing is connected to your PC USB ports I assume this is a real serial port, you could try some ferrite clip on chokes at the PC end of the serial cable, or maybe just re-routing the serial cable to the rig. What interface are you using for the RTS to PTT switching, and where does it draw power from?

See below my NTP on Quick NTP Status

 

 

Offset  does vary between 70 and 300mSec. D4 did better but this one doesn’t fail. I did add 8 pools to the pool list.

I did remove D4 and did install NTP which is said to synchronize time too.

It does seem to run but I did not find any operators panel to see if it works properly.

Any help about  NTP/NTPD is welcome.

Hi Amos,

if you are referring to the Meinberg NTP Client then you will have a tool called Quick NTP Status on the Windows start menu (hit the WIndows key and start typing Quick until you see it). It lists the servers selected for synchronization, if one is locked it will be prefixed with a '*', it may take a few minutes to synchronize, and a day or so to get really good sync. The last but one column (offset) is the difference between your clock and the server's clock, in milliseconds.

Thanks Karl (for the direct link) & others who suggested the notepad++.

Works great. Found what I needed.

Now just have to split file in two.
