Using the RTL-SDR as a transmitter

OK, this is very low power but it shows you what can be done. A QRPP transmitter or signal generator anywhere between 500MHz and 1.5GHz.

Good EU Es on 6m and 10m WSPR

Throughout the day, there was good Es on both 6m and 10m WSPR with plentiful EU exchanges of spots on both bands. So far, I have seen no evidence on WSPR of real Es DX outside Europe apart from spots by 4X1RF, although not today. See later post about 4X1RF spots.

Of course, I was not on last week.

Sunspots and 10m - June 21st 2015

Sunspot number is 84 today (K=1) and 10m is expected to remain "fair". Not that much F2 propagation, but with the prospect of Es to liven up both 10m and 6m.

Japanese goods should be cheaper!

The exchange rate (Sterling to Yen) has improved enormously in the last few years and was around 195 Yen to the UK Pound in recent days. Not long ago (2 years ago?) it was less than 130 Yen to the Pound. In real terms Japanese radios should be hugely less expensive based on the exchange rate alone becoming so much more favorable. These are not marginal changes they are huge.

Don't feel too sorry for the dealers. After all, they have to put fuel in their cars. If they struggled a few years ago they are not struggling any more! No, we the consumers are seen as easy fodder, to be milked. The dealers make big profits from early adopters who must have that shiny new radio whatever the cost. Once their greed has been satisfied, the price will drop to attract the rest of us.  I predict the Yaesu FT991 will soon drop in price. Just how much will depend on how much of the exchange rate change the dealers are prepared to pass on to us. One thing is certain, the UK dealers are doing well at the moment.

The FT817 is another story. All development costs were recovered in the first few years. As for LCD and other "supply issues" I just do not believe it. These radios have sold well worldwide for about 15 years and Yaesu has the buying power on anything. No, the true story is someone is making huge profits on this radio, and we the buying public are being taken for a ride.

When the Chinese take the amateur market seriously the Japanese suppliers and their dealers will have a rude awakening.

Jersey - NOT amateur radio

The plane we flew home in.
Well, I can recommend Jersey as a holiday destination. We had very good weather and a good hotel and room which helped. Staying in St Helier helped as the outstanding bus service was right on the doorstep. There was no need to hire a car as everywhere was accessible by the very regular bus service.

The island has small roads in the main, lovely villages, good beaches and a rugged coastline. The people were all kind and helpful. Currency is Sterling and English spoken. Most street names are French even though British since Norman times.

Overnight 6m and 10m WSPRing

Now back home again, I left my WSPR running on 6m and 10m. There was Es on both bands yesterday evening but overnight spots on 10m by local G4IKZ(18km) and on 6m spots exchanged with G0OQK (98km). No overnight Es seen here on either band.

Es on 10m and 6m WSPR

Since arriving home again after our week on Jersey I have been active on 10m and 6m WSPR. There is European Es on both bands. Now home again I shall return to normal WSPR patterns again.

Sunspots and 10m - June 19th 2015

Sunspot number has dropped to 82 (K=1) and 10m is expected to remain "fair".

GJ3XBM/P?

Maybe I should have packed my VX2 dual bander and been GJ3XBM/P? The view from the hotel bedroom is splendid and any local repeaters probably workable.

The tragedy of war - NOT amateur radio

This morning we are visiting the war tunnels made with slave labour when the Channel Is were occupied by the Germans in WW2. I am sure many Germans were pleased to be here rather than on the Eastern Front. Some were evil. The tragedy of war is that normal people are forced to do evil things. Most would rather just be normal civilians doing ordinary things. These days (different times) I am sure any visiting German people are made as welcome as we have been made by these kind people. UPDATE 1510z: Just been to see the tapestries to commemorate the years of occupation and pleased that reconciliation with the German people is high on the agenda. We live in peace.
