Show cheapest and simplest regenerative receiver the novice la Is always on the lookout tor for a simp simple leland i and cheap receiving set let which Is efficient in operation here Is what la ht believed to be the best beat in this respect ever described for the receiver the following parts parta are required one one 23 plate variable condenser with vernier one 1 inch switch lever two contact points tho the usual vacuum tube and its accessories fill the rest of the bill with the usual amateur antenna this receiver will easily respond to transmitters operating on wavelengths wave lengths from li 1 it f 7 A r 3 by breaking the connection from rotor to stator stater any Varlo moter can be adjusted to this circuit the rotor coll coil functions as ai the tickler I 1 up op to and including 00 meters the accompanying sketch explains liow how it Is done first single connections are brought out from the cwb outside windings of the varlo mete so that they can be brought out to the two contact points the leads from the inside or rotor coll of the varl ometer are connected in the plate circuit of the vacuum tube thus converting it into a tickler coll coil regeneration Is controlled in the usual manner by adjusting the rotor coll coil for reception on the lower wavelengths wave lengths the switch h arm tit t placed on the contact point marked 1 and on contact point 2 for the higher waves this Is a good stunt slant and ad well worth trying radio news new |
