BF494 is used in receiver front end. The circuit provides enough gain. I had not used any turned circuit at collector of BF494 to make it compatible for multi band operation. No AGC is provided to keep the things simple. AGC voltage can be taken from pin 12 or pin 6 of MC1496 and applied to base of BF494 through a 100K resistor.
