A few moments ago UA2FBW (1365km) was spotted on the 10FT8R RX with the indoor loop. The RX is on all day. It certainly works! His signal was strong.
UPDATE 1205z: 18 stations spotted on RX so far. The 10FT8R is obviously working on the small indoor loop antenna!
Years ago I was given a free copy of SPlan to enable me to draw circuit diagrams for GQRP SPRAT. I have no idea where this is! Buying SPlan 7.0 costs 49 Euros. which I do not want to pay.
Does anyone know of a free circuit diagram program that is easy to use please?
At the moment I have only one schematic to do (the 10FT8R).
I thought SPlan was on a CD.
I had a few problems getting the crystal pulled down enough, but a small inductor in series with the crystal did the trick. I shall tell you how I netted the crystal in another post.
So far, ES2AJ (1716km) has been spotted using just the indoor loop at -12dB S/N, which is strong. This means the "big rig" does not have to be tied up when monitoring 10m FT8.
In the end I started with my WISPY RX which I found. The sharp eyed may notice an unused oscillator buffer which can be removed from the board. A simple PCB could be made if this was ever a club project.
All being well, I shall publish the circuit over the weekend.
Years after a faulty computer system (Horizon) resulted in hundreds of sub-postmasters being prosecuted for fraud (some were imprisoned, went bankrupt or lost homes), some have had their convictions quashed.
I hope those in charge at the time are sent to prison. Why should so many innocent people suffer for the total ineptness of those in charge? Some sub-postmasters have died and some have lost marriages.
This was a cock-up on a monumental scale. You are not telling me someone at the top didn't smell a rat when so many were being convicted of fraud? At the very least this is gross incompetence. At worse, it was a cover-up.
Heads MUST roll!!
It is nearly finished, but I was unable to pull the 14.040MHz crystals low enough, so I shall have to modify the oscillator slightly when we get back, as we are going out this morning.
I can get within 700Hz with just capacitance in series, but I shall have to add a little inductance too. I was hoping to stick this RX on when out, but I shall have to wait. At least it oscillates!
The UK government amazes me by how totally STUPID it is at times!! It is only now that hotel quarantine is mandatory for travellers from India.
We have known about the problems in India for days and in the meantime lots of travellers have returned, potentially spreading deadly new variants to other adults and children who can spread it still further.
Why did we not impose an immediate ban on Indian flights or at the very least mandatory hotel quarantine, at least for now, as a precaution? This (in)action beggars belief. Some times I am flabbergasted by how stupid we can be!
