Sunspots - Saturday January 16th 2021

Solar flux is 73 and the SSN 13. A=3 and K=2.

E-field probes

There is a common myth that VLF, LF and MF antennas have to be big. Whilst this is true for radiated TX antennas, this is absolutely not true on RX. 

In the past I have used E-field probes very successfully on 136kHz RX and good ones can be quite as good (or better) than large antennas and can work from VLF to 30MHz despite being very tiny. Typical ones are just a few cms long.

One of mine, used taped to the window, is shown in the photo. Normally they are placed outdoors away from noise sources. They work because as antennas get smaller the signal level falls, but so does the noise. At low frequencies external noise usually dominates.

Winter promise - NOT amateur radio

January can be a miserable time of the year: days are short and cold and the evenings are dark and long. Everywhere looks dead.

However there is a promise of better days ahead. Soon it will be the daffodils, which are around until late spring.

Already snowdrops are pushing up and coming into flower. Promise. 

Then the buds start to appear and you sense stirrings......

2m FT8 QRP (Friday)

It is now 1125z and I have been on 2m FT8 for about 10 minutes. So far, my 2.5W to the big-wheel has been spotted by 11 stations on TX and 1 station spotted on RX.

UPDATE 1225z: 12 stations have spotted my QRP on TX and 14 stations in 4 countries spotted here on RX. 1 QSO.

UPDATE 1630z:  24 stations in 5 countries has spotted me so far today on 2m QRP TX with 2 QSOs.

UPDATE 1826z:  27 stations in 6 countries have spotted my 2m FT8 QRP so far today.

2m FT8 QRP (Thursday evening)

Last evening I was on 2m FT8 using 2.5W and the big-wheel omni antenna. Although as usual I was spotted in EI and GI, not a single station was spotted here on RX. I am pretty sure all was working here. Odd.

This was on Messenger from Steve G1KQH although I have no idea where it originated. 

OFCOM report

 OFCOM has published a report on emerging technologies. See the OFCOM website for more details.

ICOM IC-705

These QRP radios are now widely available in Europe. The price is still high and, if like the IC-7300, will not drop unless they face real competition. 

The nearest competition is the Yaesu FTDX10, but this is not a 5/10W radio and does not have 2m and 70cm, but does have an ATU and 4m.

Art with Ed - NOT amateur radio

Previously I mentioned the YouTube video made by my grandson Edward who is 11 years old. The collage shows some of the pages.
