Re: How is the SNR internally measured? #WSPR #reception

To see the exact algorithm you will need to read and understand the source code. The program measures the average signal power over the full transmission. It measures the average noise power (per Hz

Re: Time Synchronization #Timesync

NetTime can be set to update at any desired interval. I did that years ago, think I chose one hour. FWIW, my $15 Casio wristwatch gains about an hour a year. 73, Jim K9YC

Re: Time Synchronization #Timesync

Ran a test using WSPR-2 tonight. Sure enough....just as Jim and Roger indicated previously, when I forced Dimension 4 to sync time, WSPR-2 did not decode that cycle. I did not realize that could

Re: Time Synchronization #Timesync

Been using various time sync options for a long time, including GPS/Trimball. Honestly, I’ve never had a problem with Dimension 4. But, the below info re: loss of decoding is interesting and

Re: Time Synchronization #Timesync

i have one of those gps pucks that runs on NMEATIME2 from Visualgps.net. Good guy to work with but it doesn't run on my WIN 7 machine. It did initially but then it gradually never synched

Re: Time Synchronization #Timesync

Not all PC clocks are that accurate and need frequent adjustments during the day. My work PC used to lose several seconds during the day and it was hit and miss if the clock was updated when booted

Re: Time Synchronization #Timesync

This theoretical observation misses the point that NetTime has kept me within 0.1 sec for almost 15 years. 73, Jim K9YC

Re: Time Synchronization #Timesync

Hi Martin, Yes, thanks. I replied to Tim that I did find that function in the Win/API, and as I explained, since the program that wrote that uses SNTP,works fine for me, I will leave at that. Thank

Re: Time Synchronization #Timesync

Definition of monotonic: The graph of a monotonic function shows that it is either always increasing or always decreasing. The rate that it does that can vary, speeding up or slowing down, but

Yes .. uninstall all the other versions, as the uninstall program does NOT touch the location where your settings and WSJT-X log are kept. Then reinstall WSJT-X. It will find the settings and

Dave, I've seen the option to use a GPS Rx in BktTimeSync, but have not used it. A bunch of us have used NMEATime2, which the author has stated is monotonic, and from all our tests, is quite

Re: Time Synchronization #Timesync

As you have noted, unless your clock is so bad that it is stepping all the time, you likely won't have an issue with SNTP. Myself, I use full NTP (actually, run my server as an NTP server, synced to

I did change the 64-bit DLL. The file on my machine was about 1MB smaller (9.x) and the one downloaded was larger (10.057 MB). After changing the DLL, restarted WSJT-x and everything worked fine.
