Something comparable to a low-end commercial receiver, (perhaps no FM though) no audio amplifier section either. (Just pre-amp) Something very modular so you could experiment with filters and things along the stages. I tried to reply off list- but looks like you have an anti-spam address. Lots of people are building their own receivers- and many of them above average designs. I have posted this before, but here it is again for those that may have missed it: http://www.parelectronics.com/pics/w7zoi13jpg.jpg http://www.parelectronics.com/pics/w7zoi14.jpg http://www.parelectronics.com/pics/w7zoi15.jpg http://www.parelectronics.com/pics/W7ZOI11%20copy.jpg 5/2.5/.5 KHz homebrew xtal filters; selectable and defeatable AGC; tone; audio notch filter; preset BFO for USB/LSB/CW; AM detector; S meter Loosely based on W7ZOI Progressive RX from the late 1980's. Look also at Pete KE9OA's neat receiver on his site and many others. 73, That's bad-ass. Dale W4OP |
