Re: Tell me your favorite uBitx mods

I agree with many of your points, very specifically, the AGC. I tried listening in with my uBitx once I got the case wired up, and then promptly had my ears blown off by a nearby static pop or something. I haven't listened to it since, and won't until I get some form of AGC, hopefully RF-derived... I am very touchy about my hearing, as it's sensitive and you only get one set of years (I wore earplugs all new years this year... hope yours was quieter). I need to figure out the proper AGC scheme that is best, it should be reasonably easy to do.
Down the line, but a quick note: Panel space is the biggest premium I'm dealing with. The display alone takes up 3.2" of front panel space. Either one has to create a mezzanine board to 'stack' buttons/encoders/etc vertically, or you start going to the back panel, the side panels, etc.
1) Already covered above
2) Already in my schematic (I use a BY-1)
3) Already in my schematic
4) S-meter would have to be derived from the AGC, but I see no reason it couldn't be. I've added in an analog pin.
4b) I have one 'undefined' front panel button. I'd like to have more if possible... I might add in an extra MCP23S17 to expand my IO's... (I'm nearly full on the leonardo)
5) Not sure how to implement this one, but if you've got a rough schematic to point me to of your modifications, I can probably include it. Depends on how the wires would need to go to the PCB below, or if it's something that can just be put inline with the microphone. Could do a microphone amplifier I suppose... This is probably the lowest priority out of the things listed for me.
6) It's easy enough to pipe the TX line out to a relay. I'll consider it based on panel space.
7) Yep, already in the schematic. For now I'll probably stick to linear / non-phase detector method, but it probably wouldn't be hard to modify for a phase detector. Just would need to focus on how to do it on the cheap instead of using an AD8307 or 8302 (Which are like $10-25 at digikey).
