PC-based DPL decoder software??

Post by Elroy Jetson »

Does anyone know of a PC-based software package that will decode and identify DPL codes out of an audio stream,
input to the PC via the line input on the sound card?

I've found some interesting and genuinely useful software that I use regularly on my test bench to assist in testing radios,
including software that will generate multiple tones at variable levels (PL tone plus audio tone, for example) and will also
work as a software spectrum analyzer, oscilloscope, and even an I/Q modulation monitor with constellation diagram
display. It does earn its keep when I'm doing in-depth performance checks on receivers and transmitters.

But, I have yet to find DPL decoding software. Has anyone heard of such a software package?

What radios do you own?: Motorola, Icom, Sunair (HF).

I would be a bit surprised if you do find something. Recovering the DPL signal, and getting it clean enough for decoding, would be quite a challenge for many sound cards. Doing so would require excellent low-frequency response and equally good S/N ratio.

The closest thing I've heard of is WinCTCSS, which does PL tones. When queried if he was considering adding DPL capability to the package, the program's author said it would be "very involved."

If you do find something, I would be curious to hear what it is.

Happy tweaking.
