Adrian M7EFO's FB SolderSmoke Direct Conversion Receiver


Adrian has completed a very FB direct conversion receiver.  Really nice work. It is especially pleasing to see that Adrian is a member of GQRP.  FB Adrian. SSB above, CW in the video below.  I think that China Radio International signal would be a good early target for your tinkering and mods.  We fought a similar battle against Radio Marti.

Did it!!! It Works.! Receives CW, SSB,FT8. Awesome. Thanks Bill. Thanks Dean. It was fun. Now for the tinkering and modifications.

CW too. As an added bonus it picks up China Radio International radio whether I like it or not.😄

Hello. I live in East Barnet a suburb of London, UK.

I work as an electronic technician and tech support for a small company. 

My rig is a Xeigu G90 with a home made dipole cut for 20 metres and 40 metres and run QRP at 5-10 watts, 5 watts FT8, I'll save the kilowatts for boiling the kettle!  I'm using an old PC server power supply. 

The shack computer is a Raspberry Pi3 Raspberry Pi400 (Stolen Borrowed from my daughtercheeky). I am surprised at how well my set up works. Sometimes.

I am a member of the GQRP club and have started building some kits and homebrew in the Manhattan style. 

Currently studying for my UK Intermediate licence with Bath Based Distance Learning.

  1. Thanks Bill. I'll put a link to the blog on my QRZ page. First mod will be a 10k pot before the BPF to see if I can knock out some of the shortwave at night. Not a problem during the day, so I've enjoyed playing with the PTO and picked up many stations UK and beyond.
