Jara "Krysatec" ("Rat") from Czechia - EM84 Radio
I'm sending you some pictures of my constructions and also schematics and picures of my receiver with one tube EM84 magic eye!
Receiver works good with nearby stations, but I've heard also stations from other counries in Europe (in the day, but in night it is better, I hear stations also from Near East, because in NE are stations with EIRP 1-2MW too... /Saudi Arabia etc/)
Here is only one triode and audio is worse than with dual magic eye EM83/EMM801. But receiver is not for DXing...
I tested two version: with ferrite rod and fixed positive feedback and with air core coils with variable feedback. This is better.
You can use crystal earphone or 4k Ohm earphone, but it work also with my old "czech made" earphone with 2x75R speakers!

Very nice Jara. I like the variometer type coil that you updated your receiver with. I hope to make my EM84 receiver soon.
