I’ve successfully worked DXCC on 30m

Stations worked on 30m

Over the last couple of months I’ve been concentrating on 30m using the dipole I installed late last year because I was keen to complete my 30m DXCC before the winter kicks in. Most of my contacts on 30m are using digital modes, either JT65, JT9 (remember them?) or FT8 and I knew that I’d […]

UTC clock for macOS

Menu Bar UTC

As radio amateurs, time is important to us and Coordinated Universal Time (UTC), often called Greenwich Mean Time (GMT) is the most important. We log our QSOs in UTC, (ideally) we give net times in UTC and our clocks need to be accurate to the second for data modes such as FT8, FT4, JT65, JT9 […]

QSO365 #2 is complete – A QSO per day in 2018

Top ten countries worked during QSO365 #2

To start with, I’ll post the basic statistics for the entire year of 2018 and then go into the background. QSOs made: 3789 Unique QSOs made: 2962 Average QSOs per day: 10.4 Days missed: 0 <- This is the most important statistic, it means that QSO365 #2 was a success. DXCC entities worked: 160 New […]

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 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 […]

JT9 – JT65 on steroids?

A few months ago I heard about a new data mode from Joe Taylor, K1JT called JT9.  I looked into it and even tried calling CQ a few times on 40m using it but with no replies and no sign of any activity.  I quickly gave it up as a bad job but before long […]
