It took me a while to find that its for the 14 -28 m c/s band. So does it work like this:
Mixer 6L7G and Osc 6J5G produce a 1600 k c/s IF and no amplification is used. The 6K7G is the detector and the 6K7 its BFO and are only coupled by physical proximity. The BFO 'beats' the IF to audio that is heard in the phones.
All this Ham stuff is an area I have never ventured into. Is there anything on the 14 -28 m c/s band these days? Wouldnt be too happy with HT + directly on the phones!
Looked through the rest of the Mag... Luv all the old ads
Interesting, thanks Gary
