Yabancılar, hele Amerikalılar eskileri de unutmuyorlar. Bizim hiç arayıp sormadığımız, nostalji diye gülüp geçtiğimiz o eski uzun, orta dalga...alıcıları araştırıyorlar. Yakınlarda
Joachim Rabe bana bir mail atmış, alıcıdaki bazı değerleri soruyor. alıcı öyle eski ki ben kaybetmişim. kaybolmuş, kendi arşivimde bile bulamıyorum.(site silinmeleri, kaldırılmaları sebebiyle)

husnu66tr@yahoo.com Dear Hüsnü, while searching for a high performance regen receiver circuit working in the NDB-band I found you schematics in yahoo's regenrx-group.
Especially your "Three transistor VLF-LW-MW" (seems to be from 2004) and "Receiver 13" (seems to be from 2008) attracted my attention.
However, I struggle a bit with your schematics and hope you would be able to help a bit.
For "receiver 13"
I miss information on the main tank coil and it's tap to the base of Q1 (9018). What would be a good starting value for the ratio of the two parts of the coil?
Is the 2uF C at the source of Q4 an electrolytic capacitor? If yes, which side would be the positive terminal?
Can you give directions on T1 (which Toroid, how many turns, winding style) and RFC1 (I miss component values here)
For "Three transistor VLF-LW-MW.."

There's an RFC between collector of Q3 and point "C". Is that the one where you recommend to use a 500 ohm miniature transformer primary?
Which one would you recommend to build as a DX receiver in the NDB-band?
Thank you very much in advance for your kind help.
