Bee friendly - NOT amateur radio
OFCOM and EMF
Although in the UK OFCOM is consulting, it is likely that it will make safeguarding the public from harmful EMF a condition of our licence.
What this means is that if were ever investigated, we may have to prove we are safeguarding the public.
With very low power, this is very unlikely to be a problem. However, with full legal limits and big beams this could be a problem, although antenna height may well help. There are spreadsheets on the RSGB and OFCOM websites to help. Many are awaiting the final rules.
The bottom line will be that if you cannot show proof e.g. a printed out spreadsheet with results for your station, you could be closed down. Forearmed is forewarned.
See the OFCOM website for more details.
Covid-19 saliva test - NOT amateur radio
Since trials were carried out some months ago, it has gone very quiet on this. Putting swabs up noses and down throats can be distressing for some. Just spitting down a tube would be far easier, and quicker.
I am also puzzled that vitamin D and zinc supplements are not ever mentioned. Vitamin D supplements are very low cost and have strong evidence of effectiveness. I have never, ever, heard vitamin D supplements mentioned ever. Why not? If this is a "quick win" why are we not encouraged to take these? I know of several friends who are taking these.
UHF/VHF scatter
Recent QRP FT8 operations on 2m and 70cm have got me thinking. On the face of it, aircraft and tropo scatter might actually be better on 70cm than 2m.
Certainly for aircraft scatter, the smaller wavelength at 70cm might mean better scattering. I am no expert and may well be wrong. By my argument 23cm might be better still!
Certainly, path losses would be higher on 70cm, but antenna gain at each end can be easier as you go up in frequency.
What are your views?
2m FT8 QRP (V) Thursday
As an experiment, I am on 2.5W FT8 on 2m, but using the V2000 vertical antenna instead of the big-wheel horizontal. This will mean weaker reports locally as most stations will be horizontally polarised, but I would expect less difference on more distant stations spotting me. Indeed, I am weaker on the grabber at G0LRD.
So far, at 1032z, I have been spotted by 6 stations on TX with the furthermost G4TRA (185km). 2 stations spotted on RX.
UPDATE 1115z: 5 stations spotted on 2m FT8 RX with the furthermost being G4BNM (222km).
UPDATE 1312z: I am puzzled. Although I have been spotted by 6 stations on QRP TX, I have spotted 16 stations on 2m FT8 RX with the furthermost PE1KWE (307km), which is far more stations than normal. It is almost as if vertical is better!
UPDATE 1358z: 20 stations spotted on 2m FT8 RX with the furthermost GI6ATZ (479km).
UPDATE 1458z: 27 stations spotted on RX and 8 stations have spotted my QRP on TX. 2 QSOs.
UPDATE 1916z: 35 stations spotted on RX. 14 stations have spotted my QRP mostly at "tropo" ranges rather than aircraft scatter or troposcatter.
UPDATE 2222z. QRT now. 38 stations spotted on RX.

Oscar 100 narrowband activity
Every few weeks I look at the web SDR at Goonhilly in Cornwall to assess the activity level on the narrowband transponder of this geosynchronous satellite. My latest look was just after lunchtime in Europe. My "peek" suggests activity levels are still low even after 2 years.
I guess getting a signal though this geosynchronous satellite is too hard for most "black box" operators. Even if someone sold a special Oscar 100 transceiver they would still have to point the dish, which would be too hard!
I believe BATC is also streaming TV activity through Oscar 100, but I have not yet looked.
Village - NOT amateur radio
The village has grown a lot since we came in 1975, but it still feels like a village.
