UI needs more options like ppm correction entry #8
Description
Basically I love it. Running on a Raspberry Pi 3 the biggest hassle was figuring out how to use the default built-in audio device (./qtcsdr --rpitx --alsa default). But I have 3 RTL2832 dongles, each with a sticker on it giving the PPM correction to bring it on frequency. With nbfm this is critical, probably with SSB too. Even a config or rc file with a place to change it would help, it doesn't need to be done often. Squelch level? The standard options that the rtl-sdr suite has.
