Fri 12/01/24 : fldigi bug

After compiling and installing the latest FLDIGI I found a bug - if the radio dial is moved while FLDIGI is running (with RigCAT control operating normally) I found FLDIGI crashes. This has never happened in previous versions. Fldigi should just track the changing rig VFO frequency, not crash!

I ran make uninstall and removed it and simply reinstalled the Debian packaged version 4.1.18, which runs perfectly well enough, without the new esoteric modes available in 4.2.03

Ran WSPR for around 24 hours and got lots of Spots - in the USA and Australia…

Tue 09/01/24 : 60m WPSR

Brrr… it's chilly in the shack. My first trip in during winter.

I've started WSPR-ing on 60m (WARC Channel) to see how the band is performing, and to generate some heat in the shack.

And at 2050 I've moved to 10m at 5W. I heard some USA stations on 10mFM earlier in the evening. The band might be open occasionally….?

Fri 17 Nov 2023

After a couple of months away from the shack - domestic issues kept me away, and now it's winter and cold - I decided to have a look on 60m Olivia this evening, since I can do this from the comfort of the house without shutting myself away in the cold shed - the outside temp. is 0C and there's frost on the ground.

I made a VNC connection to the shack PC and ran Fldigi - it's been quite a long time since I've played radio like this.

After one CQ call at 1747z I was answered by Alan M0AGJ in Doncaster, which was a big surprise.

We had a nice, short QSO - and I found that his initial reply to me had been at only 1 watt, although he quickly increased to 100W fearing 1W was too weak. I have a feeling 1W would have been ok.

At full power his S/N was always positive, up to 18dB at times.

Mon 10 July 2023

  • A catch up from yesterday to begin.
  • Two periods of activity today, early evening on 30m and 40m, and later on 60m and 30m.
  • Rig : 7200
  • Using full 100W today - condx. seem a bit variable, especially at this northern latitude.
  • Some Auroral sounding CW.
  • Not much activity on 30m, despite many RBN spots of my CQ calls.
  • Period 1
    • 30m QSO : F5POJ : RSt
    • 40m QSO : DL6LV/P : Hry, nr Keil. BVp. Short ~RC. Should look for him again for a longer chat.
  • Period 2
    • 60m QSO : G0IIK : Nigel, nr Heathrow, RCh. BVp me: “Vibroplex Presentation 1957”, him : “McElroy Bug 1940 same age as me, 82” Another nice chat w/ Nigel
    • 30m QSO : DL4ST : RSt
    • 30m QSO : IK2MMM/QRP : RSt “QSL only electronic” = LOTW confirmation
    • 30m QSP : M0RQD : Steve, Isle of Wight : SKh. RC. slow and pleasant “beginner” QSO - hope for many more and for Steve to find CW improves rapidly with use.

Finding many RBN reports from my CQ calls - as far as Australia and Hong Kong, but very often no replies. Will endeavour to reply to any/all CQ calls I hear.
