This whole RTL-SDR thing is fascinating. Now on to figuring out getting the APCO25 decoding working. I have downloaded cygwin and am on this page RTL-SDR Tutorial: Decoding Digital Voice (P25) with DSD - rtl-sdr.com
reading the instructions. This will be a fun challenge for me. I don't like having to use virtual audio cable, I thought it would be a lot easier for instance, not having the audio go through another process in order to decipher the APCO xmissions but gee whiz what does one expect using a 12 dollar TV dongle as an SDR! If anyone's interested I used "dealextreme" website to order the dongle. It did not take long to get here and was in a package direct from China.
I also need to enclose the stick into a box, and finagle a proper antenna and connexion for it as well. This is the fun of radio- including figuring out this whole "system". Very daunting, very tedious, but that is the nature of the hobby sometimes.
I figured- before this "RTL-SDR" craze came out, that this whole TV stick as SDR was a possibility but not having engineering or electronic or programming smarts making it happen was beyond my ken. I'm impressed with the software programs and wow what genius, you know? It's just so fascinating.
Welp, between doing some major home improvements (carpet removal and other crummy stuff) I will figure out this whole RTL SDR mess. It will take time but the learning is really half the fun. Most of the talk on this forum is Greek to me but little by little I will have it figured out somewhat.
Thanks for your response
