Re: Where did the modulation go . . .

Thank you Stuart!


With your input I pulled off the text, saved it to a file, changed owner & group, and made it executable. That left only to correct 'plughw' error on approx line 246.


It seems to run now:


pi@compass:~ $ ./measure_deviate.sh.2 -f 1000 -c din6 -l 180

Using tone: 1000 (wave file name: 1000hzsin.wav) for duration 180 & connector: din6 using gpio: 23


=== Found existing wav file: 1000hzsin.wav and tone length is not default 30 seconds.

May want to delete existing wavefile 1000hzsin.wav to create a different tone duration


If using devcal from Svxlink make sure devcal line has -f1000

Using PTT GPIO 23 with tone of 1000 Hz

Now, if only we could figure out why my UDRC quit running . . . 

I still hear nothing but the right port does key.
