Ahoj!
Hi Dave!

Receiver works very good, I use ferrite rod with MW/LW coils from old russian transistor radio, and audio (LF) choke from Wehrmacht.

Because I use coils for 500pF capacitor but I use 720pF, I can tune also NDB band (nondirectional beacons for airplanes) cca 600-200kHz or band under 150kHz: I can heard also 147kHz RTTY METEO from Germany and data transmission at 139 and 129kHz too!

Earphone: you can use 4kohm earphone, also crystal earphone. I use 2x75 ohm (150ohm mono) earphone AFR200 from Czechia (also 30y old...) with small 75R speakers: it is the best!!!

Best version is with 6F31 and 6H31!
