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

It's a simple text file (XML formatted), so notepad is good to edit. My suggest is to use notepad+ with XML plugin, It helps to show a friendly view. Pietro Pietro (mobile)

Hi Jim, "If one assumes the velocity factor of a USB cable is about 80%, that means about 250 microseconds of propagation delay per meter." Let's see... the speed of light is 3 x 10^8 m/s, so the

Thanks Jim. As I suspected, there was much I didn’t understand. One good point is that the new USB3 cable is much better quality than the old one. As part of my military service I was a

Which GPSDO did you settle on Jim? I have a BG9 clone and a Bodnar. The BG9 osc has drifted beyond where it can be corrected but I'm still using the NMEA for position only. Bob -

In my testing I have tried various combinations of multiple receivers and I do NOT recommend attaching more than one reference clock, i.e. a GPS, to a machine. NTP will work with more than one, but I

One enhancement that might help in this situation is to build a call queue that allows multiple callers to be stacked and worked either sequentially or from a pick list by the operator. The progress

Paul, you need to set up the audio input and output for WSJT-X in "Settings->Audio". If you are on Windows 10 then you may need to allow WSJT-X to use microphone devices in teh Camera and Microphone

I am using a Lenovo Core i3 10 Gen running HRD and WSJT-X to a Rigblaster Advanced and a KX3. It works perfectly with an old HP Laptop. However, using the same settings on my Lenovo Laptop the HRD
