Hi,

Actually more precisely there is no audio input to codec (A/D converter in your rig or PC, USB codec or whatever happens change audio into digital format for wsjt-x).

Hi,

Do you hear the signals from your rig speaker or from PC speaker? If latter Windows has connected your rig to the PC speakers!

Bill,

Thanks for your reply. I have checked the following and confirmed as indicated. This has to

be an audio problem but I have been unable to find it. Windows 10 is not my friend.

1: USB CODEC always selected under “Settings  - Mode”

2: Getting 30 to 40 on thermometer lower left side screen.

3: checked all connections  computer to Signalink to radio. All appear to be ok.

4: RX level on Signal ink set at about 60 degrees.

5: USB DATA selected on radio, Use DATA plug on back of radio to Signalink.

6: Control sent to 0 db.

7: Microphone Privacy setting set to ON.

 

NOTE: I live in a Veterans Home. Last week we had 2 staff and 3 Veterans test positive for

the COVID-19 Virus and we are confined to our rooms. I did test negative but they are testing us

every day now.   I am not sure when I will be able to get to my station for any testing with the radio.

Always complications 😊

Thanks for your help. If you have more suggestions I will appreciate them.

Hi Dick,

using a SignaLink USB interface the USB Audio Codec devices are the correct devices to select for the WSJT-X "Settings->Audio" input and output devices. If you are not getting any indication of Rx audio input on the thermometer style meter at the bottom left of the WSJT-X main window; then something fundamental is wrong with your audio hook up. Check you connections between the SignaLink USB and your rig. Check you have the Rx level control turned up on the interface. Check you have the rig in USB-DATA mode. Check in the USB Audio Codec recording device properties in Windows that the master level control is set to 0 dB (right-click the slider and select decibels if it is not reading in dB). Check you have allowed WSJT-X to access microphones in the Windows Camera and Microphone Privacy settings.

Once you have Rx audio getting to WSJT-X then set the thermometer style indicator to 30 dB on quite band background noise using the Rx level control on the SignaLink USB interface. Then you can move on to setting up Tx audio.73 Bill

Hi Hugo,

I suspect that MS have no interest in building an NTP time server network large and robust enough to support their millions of Desktop users. Although MS do publish how to configure win32tm for high accuracy I think that they intend that only for use by network administrators within corporate networks where they have local servers providing NTP services along with AD, Exchange, file servers etc.. The configuration requires manual adjustment of a few registry values and should only be undertaken if you are comfortable doing them. You are much better off using Meinberg NTP Client which will give extremely accurate results from a basic default installation, and it allows selection of pool.ntp.org NTP server pools for reference very easily. Note that pool.ntp.org servers are mostly provided by the community, members are monitored for availability and accuracy, and they are provided for resaonable use without restrictions.

Your displayed time anomalies sound like there may be something loading your system excessively on regular basis that is causing screen updates to be stalled. That is something you should investigate further, it may well also be disrupting decoding of signals.

Ron,

while your information about the automatic operation of the Dimension 4 time synchronization utility is correct it is only a basic solution to this problem. You comment illustrates that as it is an SNTP time service client and as such only adjusts the PC time by periodically brute-force stepping of the clock. For many applications that is OK and if your PC keeps reasonably good time without any synchronization you may never see any issue. This is not the case for all users. There are full NTP implementations that will adjust the rate of the PC clock by characterizing it compared to a reference time servers known to be accurate. As such it is possible for an NTP implementation to guarantee that, after any start up adjustments, the clock is monotonic, which means there are no backward or forwards steps over clock ticks and every tick happens in their implicit order. A monotonic clock is important for real-time audio applications like WSJT-X since discontinuities introduced into sample streams, ultimately caused by clock adjustments, are likely to disrupt decoding of signals.

The net effect of the above is that we no longer recommend SNTP time synchronization tools. No doubt many users of Dimension 4 and other SNTP tools will say that they have no issues and will continue to use them, perhaps not knowing or caring that occasional failures to decode a receive period may have been due to a time step.

On Windows we have verified that the free Meinberg NTP Client, and, a low cost sync tool that can easily use a GPS time source NmeaTime2, are able to characterize an discipline a Windows PC clock without steps (with some caveats). On other platforms a suitable NTP implementation is usually installed and enabled by default if Internet time synchronization is enabled. Note that the Windows Internet Time sync tool w32tm is a full NTP implementation but by default is configured to only check time at large intervals which causes it to make steps. Configured with default settings w32tm is effectively a low accuracy SNTP tool.

On May 22 this year I contributed this to the Group about the PC clock setting program «Dimension 4»:

 

In Dimension 4 you MUST open (run) the program, choose «Settings», and answer «yes», to let the program make time changes in your PC.

 

If not, Dimension 4 will not adjust your PC time clock. This procedure has to be done every time the PC is started or restarted – else it may not adjust your PC clock.

 

Then check if the time is within +/- 1 second of correct time by RELOADING for instance www.time.is

 

If the PC time is not good enough, right click the Dimension 4 icon on the PC’s lower right command line, and select «Syncronize now». After some seconds (at least some 10 seconds on my PC), RELOAD www.time.is again, and check if the PC’s clock has changed to an acceptable time. If still not good, repeat this procedure, until the PC clock’s time is acceptable.

 

I have used Dimension 4 this way for many years, without problems.

Testing conditions:
* The distance between TX and RX was about 10 meters
This does seem close, if both were connected to dummy loads there would still be ample signal pickup.

Result of FST4W-300:
* On 7.0388MHz + 1536Hz: undecodable
* On 10.1389MHz + 1536Hz: undecodable
Frequency drift of FT-891?
With a recommended maximum of 0.56Hz for -300 this is quite possible.

The HF+ is quite stable in the short term when warmed up. Using software like Spectrum Lab you can monitor frequency very precisely.

I am not convinced there is any need to use FST4W on the higher frequencies but there may be times that there is an advantage.
