It is simple experimental receiver that was made on
two tubes- twin triodes. The receiver was tuned to 80- meter amateur
band. Schematic of the receiver is shown on Figure 1. Video of the receiver is: https://yadi.sk/i/BRXlyqr8evRf8
https://www.evernote.com/shard/s556/...0%BE%D1%81.amr It is usual DC Receiver with phase suppression of the
second side band. Book "Direct Conversation Technique
for Radio Amateurs" (Antentop 01-
2015, p. 88) gives information how to tune and adjust such receiver.
Figure 2 shows design of the
receiver. Receiver consumes current 4.3-mA. VFO consumes current
2 mA. Figure 3
shows the current. Figure 4 shows shape of the RF signal of the VFO.
Receiver could work fine with antenna in several meter length.
It is possible use players low ohmic
headphones turned on through transformer or high-ohmic
(2x 2000-Ohm) phones turned on to tube plate through capacitor
47.0-microF/16-V.
