472KHz WSPR

I'd read around of people using Icom 706s, which apparently transmit a peep on 472KHz, and thought I'd polish the 756 ProIII and see what I could do. No possibility of transmitting - I haven't a NoV, and I suspect I don't have an antenna suitable.So I thought I'd try listening.

No preamp (the Icom Pre-Amp doesn't turn on in this frequency range) but connected it up to the usual LW. The tuner doesn't seem to do very much either, but there was a ripple of activity on the spectrum display

Started up WSPR, and left it for half an hour, and here's the result.

Much better than I expected. The received wisdom was that an external preamp is needed. Well, it would undoubtedly make a difference, but I'm hearing these two guys at about -13dB, so it's "comfortable" (for WSPR).

And a nice way to open playtime with 630metres.

JT9-1 success

I downloaded v0.5 of the JT9-1 experience from Joe Taylor's Website - you want WSJT-X - and it's a MUCH better experience. It all seems to work nicely.

I've tried it relatively low power (around 10W) on 160 metres, and have worked my way up to middle europe on it. The QSOs are reliable, it tunes well, and it's acquired some of the enhancements that HT65-HF has - the red and green bars, the click to continue the QSO. And it is MUCH more spectrum frugal than JT65 - and yes, it even gives positive reports sometimes

All good. I look forward to working you :-)
