RX 20 - Initial Circuit

Hello :)

I had been QRL with college and did not find time to update this blog.

I quickly opened the BITX circuit diagram and made some quick changes (removing the TX RF/IF/AF amplifers) ....

Take a Look at the circuit here . It looks much simpler now doesnt it :)

There are several optional additions to the circuit such as a Automatic Gain Control, Digital Frequency Display and also a Active/Passive AF SSB respsone filter which will be added later on


More in the next installment :))

when ever you will get time, try to draw the diagram as block vice such as RX Amplifier, BFO, Modulator and so on. It would be helpful to all people even though they don't have much idea about electronics. It will simplify the diagram :)
