ICOM IC7300

It still surprises me that the price of the IC7300 has not dropped. I guess the dealers are playing "chicken" to see who blinks first. If people are happy to buy at the current figure they have no incentive to drop the price. Meanwhile, they all make lots of profit.

10m WSPR TX

As usual, I am on 10m WSPR TX (500mW), although no-one has yet spotted me.

UPDATE 1400z: Two 10m WSPR spots so far today with DG7RJ (916km) the best DX report so far. I assume this is Es.

UPDATE 2202z: With late DX (Es?) spots from EA, I and DL I decided to leave the 10m WSPR beacon running overnight. I have gone QRT on 6m FT8 RX.

6m FT8

As well as G3PXT, I am spotting Germany and Slovenia on 6m FT8. These could be Es or random MS. For random MS, the 15 second periods must help. There was slow QSB on G3PXT (79km), so I think this was tropo.

UPDATE 0942z: G4VXE (136km) now being spotted, although no further non-G DX spotted.

UPDATE 1358z: S51AT (1250km) is the best DX spotted so far on 6m today, with 5 countries spotted on 6m FT8 so far today.

UPDATE 1545z: 9A4ZM (1292km) in Croatia brings the total to 6 countries spotted so far today on 6m FT8.

Sunspots - Wednesday September 6th 2017

Solar flux is 122 as is the sunspot number. These are massive figures this late in the cycle. A=12 and K=2.

Es on 10m and 6m

Although I was away at my son's for a few days, I went on 10m WSPR TX and 6m FT8 RX on my return. There was Es on both bands.

2m UKAC activity contest (September)

A reminder that tonight is the RSGB's 2m activity contest. It runs from 8pm to 10.30pm UK clock time.

UPDATE 2050z: Although I was only of for about 15-20 minutes, best DX was M1MLM/P (181km) in the Peak District. As usual, I was using 5W QRP to my big-wheel 2m Omni.

Sunspots - Tuesday September 5th 2017

The solar activity is incredible for this part of the cycle. Solar flux is 144 and sunspot number is 122 (incredible). A=18 and K=2.

Low noise VLF pre-amp

In recent days there has been quite a lot of work on different VLF frequencies (as low as 970Hz) by amateurs trying to receive carriers and short messages at great range, including from Germany to the UK. In a recent posting DG4RBF gave details of his latest pre-amp. I have no idea if it does the job. The text is in German, so you have to translate if you want it in English. Use Google translate?
