Simple SWL HF- VHF Receiver
Simple SWL HF- VHF Receiver: From the book "DX Reception"
(by Igor Grigorov (RK3ZK), Belgorod, 1994), pp.:76-
81.
Using only 4 cheap surplus transistors and 1 mixer SBL- 1 you can do a HF- VHF receiver that provides good reception on HF (12- 29- MHz) and ex- Soviet BC FM VHF- 61- 88 MHz. Receiver catches AM and FM with deviation more the 25 kHz. Such receiver allows very quickly to find a propagation on the spectrum of HF and VHF bands.
