Gareth, I would be interested in seeing your version using the intel encoder. I'm using a i7 10th generation processor in a MicroPC without room for a NVidia video card.

Anyone recognise these wideband signals? They have been showing up in the early mornings for the last week and fade away by noon. They look to be 60-80Khz wide. Wonder if they are some kind of Radar?

HF radars

Plenty of them about, all using different modulation types, repetition rates and bandwidths.

Radars located in Cyprus, China, Russia and Iran, are usually the ones most commonly heard.

Now find that when editing the 29mhz transverter BOM.xlsx prior to uploading to Digikey I mistakenly deleted the entry for K1 relay:- Omron G5V-2-H-DC12.

Looking at suppliers for this £3.00 item, all quote the postage of £10+.

I would be very grateful if there is anyone who has a surplus relay that they are willing to sell to me p&p incl.

Regards

Peter.

Many thanks for the ebay links Gareth and Mike, not sure why it did not show when I did a search but I've ordered it now.

Regards,

Peter.
