Radio and rails...

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…

I had my first BPSK-63 QSO today. I like these modes, just set the rig to 14.070 and follow the matrix-like display... with no audio to annoy the wife. Mind you, as yet I have had no success having a CQ answered. I've sent plenty but currently the rather poor drive from the PC results in very little RF power. I hope to rectify that next week. There is a lot of RTTY about with the BARTG contest. Plenty of decodes but I've not joined in because I am not up to entering. Once the contest ends I'll have a good sniff for RTTY. Pity I don't have a nice old clattery Creed 7E to do it properly... but that is probably a step too far as I am still only a lodger in the spare room (aka study, aka shack) and may well be turfed out into the shed!

Typical. I tidied the setup today and got everything into a better position for working - as you see in the photo now. And now there are stripes of noise across the waterfall in fldigi - as you can also see in the photo! I've moved everything about again to try to cure it to no avail. Something has clearly moved nearer to something else and they don't get along. Grumble...
