Seen on a recent amateur radio post

 This appeared recently just below the signature. It made me laugh! 😊

OFCOM and EMF

OFCOM has announced some changes to licence conditions. I think these are about EMF. They are sending revised licences to those affected. See the OFCOM website for more details.

10FT8R - continued experiments

This morning, I am again on 10m FT8 RX with the tiny indoor loop. Late yesterday, I removed the last AF stage, but spotted no stations. There were lots of spikes and I am not sure what they were. Later, I shall stick the last audio stage back again to see if this was important.

UPDATE 1010z: Something is wrong. On the 10FT8R RX no spots, yet when I went back to the FT817ND spots right away. Some spots were strong. I must be doing something stupid. More investigation needed.

UPDATE 1206z:  9 spots so far.

UPDATE 1411z: I have put back the final audio stage on the 10FT8R RX and the spikes have gone (no idea why) and I am spotting lots of stations again with this little RX connected to my indoor loop. At the moment this is the RX being used on 10m FT8 RX. So far, since reconnecting it, 20 stations spotted.

South Devon - NOT amateur radio

This is a another photo of where I come from in South Devon. In the distance are Dartmoor and Cornwall. 

Sunspots - Tuesday May 18th 2021

 Solar flux is 75 and the SSN 11. A=6 and K=3.

10FT8R RX - even simpler?

At present, I am experimenting to see if I can omit the last audio stage. There seems to be plenty of spare audio. Being a DSB design, it is inherently 3dB down in sensitivity, but that has not been an issue hitherto.

Oscar 100

Every few weeks I try to give an update on activity levels on the narrowband transponder on Oscar 100 using the on-line SDR at Goonhilly Down. I looked twice last evening at times that would have been European Sunday evenings. 

My impression was that activity levels were quite low with plenty of space.

10m FT8 grabber

One of the things now possible on my new web pages is embedding. This has allowed me to add a grabber, so you can see what I am doing on PSKreporter maps. I think you can change the menus. Certainly I can. At the time of writing, I am looking at the last few hours on 10m FT8 RX.

Breakfast? - NOT amateur radio

This has appeared on social media several times. 

As much as I like the occasional fry-up, even I would struggle! 

Some would be very much against this.

Ivermectin - NOT amateur radio

Ivermectin seems to have anti-viral properties against Covid-19 in helping to prevent serious illness. 

Some governments (Goa in India and Ireland) are recommending this very low cost drug as a prophylactic. I regularly watch the YouTube channel of Dr John Campbell and he is puzzled why this is not being widely recommended. He always gives the source of his data. I recommend you check this out. 

Always seek the medical advice of your own doctor!
