All outputs will be asymmetrical; reduce the Post Amp slider to compensate for the extra needed headroom.

Thanks for the answer.
Would it be possible/make sense to only make the transmitter output asymmetrical so that the LQ / NO is unaffected? (monitoring etc.)

Maybe renaming the FM soundcard ouput the 'transmitter soundcard ouput' and being able to switch between AM transmitter or FM transmitter might be an option? If you are considering implementing more AM features like a NRSC filter or pre-emphasis, this might make sense?

Would be interesting to hear the AM users opinions on this...

I would say add a separate AM Output.

Red output bars are not fixed. It still happens sometimes.

Right now the AM support is kinda limited, for example in the US if you want to use 75 us pre-emphasis you need to enable FM processing as well (!). I will probably fix this and make it more logical later, for now the feature is available for the (probably very few?) AM stations that can use it.

Thanks to NRSC AM bandwidth was compromised. Old AM could sound amazing!!

Wow. Turns out that all the Jack issues I was having were caused by a corrupt Linux install... I re-installed it last night and now everything starts up as it should!

I know Linux comes in several flavors.Would any of you mind sharing what versions you're using. Kinda got my interest stirred up here.

New Linux GUI version, now with Jack support. No parameters needed!

ONLY FOR TESTING, this version is not at all suitable to do actual processing, I just want to know if it works properly (sound comes out, no hiccups).

Notes:
- jackd must be running (use qjackctl to see what's happening - you should see it connect there).
- Only normal input and normal output work, for now.
- Because I'm not sure if I'm doing everything correctly yet I'm adding a soft beep tone to the input.
- FM presets don't work and output silence - I don't know why yet. Use default settings (no processing) or generic or web presets.
- Program closes after 60 seconds!
- Latency is hardcoded to be 250 ms.


Testing this in a VMware environment is giving pretty bad results (some weird things happen with the Windows sound drivers in combination with VMware as soon as I start jackd; after killing this Windows driver everything works fine but I can't hear anything), I need to do a native install on another pc for proper testing.
