There is a real gap in my knowledge as I have never once tried an SDR based receiver or transceiver. SDR dongles are very low cost, so I really have no excuse.

On the Southgate site I read news of a new SDR 5W transceiver.

A little while ago I decided it was time to get a little help with my CW. Whilst I can have a reasonable QSO whilst I’m sat in the shack I tend to make a complete hash of it when /p. The bottom line is that my head copying skills just aren’t there. To try and fix this I enrolled on the CW Academy course for the slightly less than novices (Intermediate). I had expected that I was slated for October but it seems that we’re starting on April 1st! Hope there’s no significance in that.

In this video I show a few things to test before adding an “On The Air” LED indicator to a Kenwood TS-50 ham radio transmitter. I tested for the best brightness of the LED and lowest current using a ganged restore test box I built. The LED was then mounted in my Kenwood MC-60 desktop microphone.

Speaking of 'everlasting', wimpy Solar Cycle 24 has been showing more energy in its death throws than it ever seemed to show during its peak.








It continues to blast earth with a never-ending series of coronal hole streams leading to periods of high signal absorption (particularly on the lower frequencies) and widespread auroras.

The present rip in the Sun's surface is the same one that caused major disruptions during the last solar rotation. Geomagnetic storming and propagation disruptions are forecast to begin around the 28th, with a proviso ... these ones could be even worse than last time as the wind's polarity at present is favorable to greater coupling with the Earth's magnetosphere, sending the Earth's Bz southward (negative) into auroral producing, prop-killing conditions.

Sometimes, though not normally, these events can produce periods of enhanced low frequency propagation, especially during the hours just before the event's commencement ... the best thing to do is just continue to operate normally and not assume the worst. I've been guilty of this in the past and being caught off guard, have missed some better than usual LF propagation.

 I'll keep my fingers crossed over the next few days and think positive ... Bz-wise!
