Amateur radio ⁽²⁵⁶⁾

One thing I've noticed is the screen required for these digital modes. I have a 22" 16:9 screen and I had a secondary 19" 4:3 one attached when I was writing my Ph.D. but it generated a load of RF hash. So now I just have the 22" and it's not big enough! Many shack photos show dual screens or even dual PCs and multiple screens and I can see why. Ok I have the MacBook for logging and other things, but the shack PC desperately needs more screen size and/or more screens. Something else to work on. Unfortunately the PC is a scrapper that has no HDMI output so I am limited to a DVI and a VGA screen. Hmmm... so I need a better PC too... I am just beginning to experiment with JT65 having set up WSJT-X recently and the screen is full.

So far I have totted up 19 countries - finally including the UK. I managed a BPSK63 QSO with a station just a few miles away, on 20m again as this is still my only HF antenna. I'm guessing this was ground wave. Funny, I've been interested in, and fiddling with radio for 40+ years and yet I am only now learning about propagation, helped in a large part to the two pieces in TX Factor. See http://www.txfilms.co.uk/txfactor/ - these are really good programmes.

I've seen several BPSK125 calls about 20m but missed them all - they are so fast that by the time I settle on one QSB has knobbled it. But tonight I managed a short QSO with the Falkland Islands no less!

Nice sunny Saturday here and I failed to get a reply in to several BPSK31 calls but then managed to reply to a CQ on MFSK16 - another new mode for me. MFKS16 is quite a 'fat' signal compared to the PSKs and I had to scrabble about for my printout of modes to see what it was. I tried Domino first to no avail, then found the red bars in fldigi just fitted MFKS16 and it decoded nicely, and an eQSL to boot.

I solved the drive issue... got a SignaLink USB box which has its own sound card built in. The box needs four wire jumpers installing inside and these are supplied, along with a diagram of where they need to go. The Allen key needed to open the box is also provided. This device plugs into the FT450D's Data socket and a USB on the PC - no audio leads needed. It was quite easy to set up except Linux is not supported officially and the sound setting instructions are for Windows. But, hey, you run Linux you are sort-of expected to know stuff, right? So I figured out what the sound card was called and found it in in Pulseaudio - it found it as PCM2904. My settings in the Pulseaudio volume control - so far so good - are: Playback - playback on PCM2904 - I set the level to 100%. I tried this at 50% but got no 'music' when listening via the ICR2; at 100% it 'sounds' fine, and obviously worked because I managed a QSO. Recording - capture from PCM2904 - again set to 100% Output devices - PCM2904 and 100% Input devices - PCM2904 and…
