I have been using the WSJT modes since the JT65/JT9 days, until now on FT8, JS8 and I don't think I am doing too bad, given my compromise antenna. Since then, until now, I have not used the WSJT-X

I am well aware that ntp needs 3 or more sources of time. In the experiments with multiple GPS sources, there were also several network time sources defined so ntp always had at least 4 sources to

Hi Tom and Reino, the way the newer 77-bit payload protocols work with /P and /R callsign suffixes is not quite the same as standard callsigns, but has less restrictions that other

>I would much prefer to follow recommendations than risk misunderstanding. Also WSJT-X treat /P, /A etc as ’standard’ callsigns so no issue there. Hi Tom, Have you tested how /P, /M, /MM,

Karl Please remember Amateur Radio is world wide - so FCC rules may not apply and people should be advised to check their own licence wording. In the UK while it is not mandatory to send /P, /A etc

Hi Jim, The fundamental error here is using 2 clocks as reference, it doesn't matter that they are both GPS. NTP specifically requires 3 or more to arrive at correct time. But

Yes, that too. But as I observed in my response to Dana, a grid square provides far more information to others considering whether to work you and where to point their antenna than does any of those

Jim, I would not say it is a bad idea, it is a user choice. Complaining that that you can't add a gridsquare to your CQ calls if you are using a nonstandard callsign is a bad idea, as

No. But for the reasons Bill cited, doing so is a bad idea. 73, Jim K9YC

 Do the rules part 97 PROHIBIT using suffix? I kinda like seeing those suffizs because it offers addition information. Just my 2 cents worth.... Marion, K4GOK On Mon, 19 Jul 2021 14:05:09

Hi Bruce, simple answer, if you want weak signal efficiency then don't start with something like BAUDOT using FSK at 45.5 baud. Of course authors of soundcard RTTY decoders have explored and

Karl, modes like FT8, FT4, MSK144, Q65, and FST4, which all share the same basic source encoding rules, have a great deal of flexibility for nonstandard callsigns (by non-standard I

This has been well covered recently in this forum, almost to the point of becoming annoying. Please take note and pass the word to your ham friends. 1) FCC RULES PART 97 DOES NOT REQUIRE OR EVEN

Joe: I am completely agree with you! And in my unscientific means, it works well enough to keep your time for WSJT-X working. It may not be as accurate as a yottasecond (Ys or 10 to the 24th), but it

I have always been in awe over the signal processing and error correction techniques used in the assorted WSJT-x modes....and my curiosity compels me to ask... I wonder if any of these techniques

Yeah, sometimes there is a disconnect between the brain and the fingers... What it should have said is the propagation VELOCITY is about 250 meters per microsecond or 4 nanoseconds per meter. For
