1.install BOTH Virtual C 2015 runtime 32 AND 64 bit I 2. nstall GNU radio, msys, and wintelive as per instructions of curly boy 3.check for tetra channels with SDR sharp. If signal(s) is well above noise floor Wright down strongest channels on a paper. If signal is very low you need a proper antenna cut for the tetra frequencies in your area.If you need help with the UHF antenna check this http://www.changpuak.ch/electronics/lambda_4_gp.php. DON’T use excessive gain id SDR-sharp. Reason is with too much noise, program will not decode tetra traffic or decode partially due to the noise. Check with SDR how much gain is necessary without raising noise floor and write it down. 4 Reserve resources from your computer, that is switch off all unessasary processes ! VERY IMPORTANT, switch off antiviruses, windows wall, windows defender, wifi, google crash etc this will help to take an idea https://support.focusrite.com/hc/en-gb/articles/207546695-Optimising-your-PC-for-audio-on-Windows-8 5 Press control-alt-delete and again kill all unnecessary processes 6 Open wintelive_10channels.grc with GNU radio and DISABLE all 10 channels in the GNU graphic except one, that is you are left with ONE channel (press on each box and select “disable” 7. On the left of GNU grafic find “Variable ID:sdr-gain” box and replace 33 with the gain you found necessary from SDR sharp 8 Next to it is “Variable ID:sdr_ifgain” box replace the 20 with something accordingly to the sdr gain you inputted for exemple for sdr-_gain 18 sdr_ifgain gain should be 10 8 Execute the flow graph. Wait for everyhting to load and the graphic to start working 9 open msys and type” muxrec 1 ” . That is you are going to use ONLY one channel 10 open wintelive. Don’t use “allscan”, “bandscan” they work very poorly. Enter manually the frequency of your preference that you found from SDR-sharp and you wrote down on paper.. Press tune. Program should start to work. New frequencies will start to appear on the “Discovered frequencies” box 11 Check if you are having a lot of SDS messages. That means everything is OK. You should hear voice Now !!!! 12. if you are sick and tired of the litlle wav files download http://s000.tinyupload.com/?file_id=82874511767130783086 and replace wintelive exe with this, with the new new exe wav’s will not be written and program will not crash after shutting down SDS messages box. (program is not mine it’s from “holger”…)﻿
