Message Date From Subject 1298 2008-01-03 19:10:30 Clark Fishman Hycas I have not put the Hycas together yet but I am speculating that a single stage with 3 or 4 J310's (each with it's on source resistor) in parallel and maybe a 2N5109 or 2N3866 in place of the 2N3904 and suitably biased would have one hell of a good dynamic range. I'll try to take some measurements this week on both configurations

Check out my 9.000 MHz product detector and audio pcb. It has a four pole post IF xtal filter, usb/lsb/cw carrier oscillators, mute and sidetone circuits. A TDA2050 gives superb audio.
