Re: [wsjt-devel] Beacons / Non-synchronous Mode

Another option to consider if using a computer ( i.e. Raspberry Pi or other ) connected to the internet is to simply set up ntp or chrony for time keeping on that computer. NTP should keep your computer clock to within a few 10's of milliseconds - well within the needs of WSJT-X synchronous modes.

And not only that, there are legitimate users of WSJT-X that are not licensed amateru radio operators. For example SWL users and experimenters on ISM bands. Restricting something in the ways suggested just doesn't work, it just doesn't stop the abuse. You are supposed to have a driver's licence i

Indeed, pskreporter of course can not do anything with something it doesn't get. The dependency is of course on the client software and what it does. I did some more testing prompted by Reino's postings. FN25 VE3GHM does not get sent to pskreporter by WSJT-X, likewise nor does VE3GHM FN25. CQ VE

Hi Reino, Belt and suspenders - WSPR is the belt and would be the primary tracking source providing, location and encoded in the power field altitude in some transmsissions, and temperature in others; FT8 would be the suspenders as a secondary mode and just provide a position using a four characte

I will do some more testing, it could have been that my testing methodology was flawed. I will play around some more with your example. yes indeed, it is getting truncated. The FT8 encoding found in Jason's NT7S JTEncode Arduino library will encode free text but nothing else. and since my call is

Hi Pete, Short term yes, atmega328 long term doesn't matter so much i.e. samd21, stm32, teensy or whatever. The idea is to be able to provide a secondary mode to WSPR for a Pico Balloon tracker. WSPR works well as primary mode but the desire is to have a secondary mode as well - kind of a belt an

2020-01-01 Thread Graham c
I have been working through the code that does the encoding of standard messages in FT8 with a goal of creating a simplified version that can compiled and used on an atmega328 processor (i.e. Arduino). There is an Arduino library called JTEncode which includes FT8 but this only encodes free text m
