Accurate time keeping on an Apple Mac running macOS Big Sur for FT8, FT4 and WSPR

ChronyControl

2023 update – This still works with macOS Sonoma and Apple Silicon. I’ve been using Apple computers for many years now and even though I’ve made a couple of previous blog posts about keeping the clock accurate on a Mac, those methods have never really been needed and I posted them as a sort of […]

If you use WSJT-X for FT8/WSPR/JTx etc, you should upgrade to V2.0.0 as soon as possible

WSJT-X version 2.0.0 has been released and everyone who uses this software for any data modes should update as soon as possible.  This new version is NOT compatible with previous versions so everyone is encouraged to upgrade to 2.0.0 as soon as possible. New features in WSJT-X 2.0.0 Compound and nonstandard callsigns are automatically recognized […]

Accurate time keeping on an Apple Mac running macOS Mojave

When running data modes such as the very popular FT8, it’s important to keep your computer clock accurate because if it’s more than a couple of seconds out then you won’t be able to decode anyone, they won’t be able to decode you and you won’t make any QSOs.  There are a number of utilities […]

Accurate time keeping on an Apple Mac or Raspberry Pi for WSPR/JT65/JT9/FT8

If you use any of the data modes for QSOs such as JT65, JT9, or FT8 or if you operate using WSPR then you’ll know how important it is that your computer clock is accurate.  Anything more than a couple of seconds out and you won’t decode anything and nobody will decode your signal. On […]

What can be achieved in twelve hours of 20m JT65/JT9?

WSPR is great, I enjoy running WSPR and seeing how far I can transmit using very low power but there are a couple of drawbacks.  I appreciate this will sound as though I’m knocking WSPR but trust me, I’m really not. Firstly, it’s not a QSO mode.  I accept that many years ago, some QSOs were […]

JT65A, working DX with low power

Over the last few months I’ve mentioned JT65, or to be more precise, JT65A a lot and it’s fair to say that I’ve had a lot of QSOs using it.  In fact, at the moment it’s probably my favourite mode of operation.  I explained about how a contact is made using JT65 in this blog […]
