![]() ![]() If you do, you are probably listening to a very weak signal, have some interference, have a bad discriminator tap, or have iproper settings in SDR software.Īs for encryption muting on DMR, NXDN or anything other than P25, I don't know whether either application supports the muting of encryption for anything other than P25. So it's entirely possible that once in a while, on a P25 signal, you might hear a few blurbs of encrypted audio. If you ever hear encrypted audio, it isn't because DSDPlus isn't doing it's job - it's because the required information was not able to be decoded that tells DSDPlus that what follows is encrypted traffic. On DSDPlus there is P25 encryption muting. On some others there are, but it's broken. On some versions of DSD, there is no P25 encryption muting. Hearing encrypted audio may be useful at times, but as a general rule it is a nuisance and that is why the "mute" option is available. Why? Because there is no reason to listen to encrypted audio, especially if there is never a hope of that encrypted audio being decrypted. The term "muted" is used because DSD (and DSDPlus) both attempt to mute encrypted audio. If you're hearing audio that sounds like it's encrypted with moments where you're hearing clear audio, then the audio being transmitted was clear all along and what really was happening is that you were getting a bad decode. In fact, it would not be possible for the code to do this without some sort of input from the user even if the application supported decryption. The functionality does not exist in the code. Neither DSD or DSDPlus will decrypt encrypted audio. Just to avoid any confusion anyone might have: Then I simply re-run DSDPlus using new options. If I want to change options, I hit ESC and am then dropped back to the Command Prompt. * I type dsdplus -f1 -O NUL -v4 (or whatever I want for switches) and hit enter Įxample: My DSDPlus binary is called dsdplus.exe. You might want to consider opening a command prompt, navigating to the directory where dsdplus.exe exists (if yours DSDPlus is still named dsd.exe, you should change it - it's not DSD), and then run DSDPlus from the command line. If you can, you must have some magical version of DSD that I've never used. I have to cry foul and suggest that you are not correct when you state that you can run DSD and change invert / mode / etc while the application is running. The only way I know to invert polarity or change from one decode option to another is to do it from the command line, while the program is not running. As far as I know, there is no behavior of DSD that can be changed while it is currently running. ![]() If you can change operation of DSD after the program has been executed and is running, I am not familiar with that functionality. If you expect DSDPlus to behave exactly like DSD, you should not expect that. The author of DSD / contributors to DSD and the author of DSDPlus are different people. ![]() I've never had it happen, but at least one person in the forums has.ĭSDPlus should never be confused with DSD. If you hit CTRL-C, you might end up with a. Please read the the thread and the dsdplus.txt text file.ĮSC is the proper way to exit the program if you want to make sure that any recorded audio. ![]() In fact, just a bit further up in this thread (in the last day or two) I believe this was discussed. If you were to read dsdplus.txt, you'll see that CTRL-C and ESC do not do the same thing. Which has the same result as pressing the "ESC" key. I CANNOT get to a command line to make any changes because DSD Plus will not accept any keyboard entries except so far "CTRL C". I can change from a NXDN 4800 baud search to a 9600 baud search and do positive and negative searches. When my "regular" dsd.exe" is executing, from the keyboard I can change from a positive to an inverted MOTOTRBO mode search. Out of curiosity I thought I would try DSD Plus never expecting the problems I am encountering. "dsd.exe" defaults to MOTOTRBO and P25 Phase 1 decoding. Using my R7000 receiver with a Win7 OS HD sound card and using the same antenna input, I can receive farther distant state trs sites because that dsd configuration is more sensitive that my digital scanners. and use it frequently in logging and identifying MOTOTRBO signals plus some P25 Phase 1 signals from more distant sites on the Virginia state trs. I configured my "regular" DSD software/hardware configuration almost 2 years and am familiar with commands, switches, etc. ![]()
