136kHz RX

As 10m and 6m were quiet, I have QSYed to 136kHz RX on WSPR and OPERA.

10m WSPR TX beacon now ON

The 10m 500mW WSPR beacon has now been turned on. This is on TX 100%, but the frequency is randomised. No spots yet.

UPDATE 1655z: No spots.

UPDATE 1835z: Still no spots, so QSYed to 136kHz RX.

6m MSK144 RX and 10m WSPR TX

Although I am on 6m MSK144 RX, I may well turn on the 10m WSPR TX beacon as conditions look quite promising. I can do this as I use a different antenna and the beacon does not need a PC.

UPDATE 1354z: No spots.

UPDATE 1650z: GM4FVM (428km) spotted very strongly (+10dB S/N) earlier this afternoon.

Sunspots - Thursday February 7th 2018

Solar flux is 77 today. Sunspot number is 20. A=4 and K=1. This is the highest sunspot number for some time.

Sydney Sussex Collee, Cambridge - NOT amateur radio

This is another view of Sydney Sussex college in Cambridge. I pass this every Tuesday and Wednesday. Cambridge is filled with ancient and beautiful buildings.

Commradio CTX-10 transceiver

Although shortly to be available in the USA, I am not sure if this will be available in Europe which needs CE approval. It is a very small 10W QRP radio that can be set at 1, 5 and 10W. In the USA it will sell for $999.

The CR1a receiver has been available for some time. There are quite a few YouTube videos of this.

136kHz WSPR RX and OPERA RX

At about 1920z I QSYed to 136kHz RX from 50.280MHz (6m) MSK144 RX.  As yet, no spots.

6m MSK144

Yet again, I am monitoring 6m MSK144 on 50.280MHz. Most days this produces spots from several European countries. The main propagation at this time of year is random meteor trail reflections. Signals are brief, but often strong.

UPDATE 0904z: No spots as yet.

UPDATE 1410z: S59SV (1280km) in Slovenia spotted strongly this lunchtime.

UPDATE 1615z: GM4FVM (428km) spotted strongly this afternoon.

UPDATE 1702z: No further 6m MSK144 spots since the GM.

Sunspots - Wednesday February 7th 2018

Solar flux is 75 today. Sunspot number is 17. A=5 and K=1.

Low cost advertising - NOT amateur radio

My wife reminds me that it is possible to advertise in the programme for the upcoming Cambridgeshire Choral Society (CCS) concert in early April. This programme is widely seen and rates are very reasonable indeed. £50 for a full page. £25 for half page. The booklet is A5.

Should you wish to advertise please contact me in the first instance. More details are on the CCS website. This is your chance to reach many for very little.
