I could, But the idea is that is plugs in at the front for the Audio connector and then lines up at the back to sit in the same foot print as the original LPF section. I will align the mounting holes

Actually I was asking about the BFR vs 3904... I didn't notice the BFR93W in there until you pointed it out. BFR106 vs the BFR93W, essentially the same thing in this application, the 106 has a higher

Also: 4. "change the resistors R26 and R46 to 220 ohms (from 470 ohms)" V5 diagram still has R46 at 470. 73

Hi Farhan. Great work. 3 Quick questions, I hope.... 1: How do you test your XTALS for the 11.0592mkhz SSB filter? Matching them? Tolerances? 2: I see you still have Audio running via M1 /M2 relay, sa

Spurs/Harmonics fixes for v4 based on v5 board design?
Hi All. I have a question relating to this. I am testing 11.0592 xtals for replacing the 12mhz and trying to match them. I have a xtal oscillator and feed that into a ham it up and a RTL SDR. Now as I
