[hpsdr] Where to inject sub audible tone for repeater access into Janus card?

[joetorrey at cablelynx.com]

Thanks for all of the replies; I look forward to more discussions on this
as well as some help regarding software to make this happen. I have tested
the transmitter on two meters regarding repeater use and all works fine
but would like the option of PL tones also. I presently use the inbuilt
signal generator for receiver alignment - level and image rejection. I was
approaching this from a hardware standpoint but if possible software would
definitely be the best. Any pointers on where to look in the code would be
much appreciated.
