For tests I use only command line tools: w_scan & dvb-fe-tool Tests: 1) w_scan on first front end then after 5-10 seconds w_scan on other 2) w_scan on second front end then after 5-10 seconds w_scan on first 3) "dvb-fe-tool -d DVBS" on first front end then after 5-10 seconds w_scan on second front end then after 5-10 seconds w_scan on first 4) "dvb-fe-tool -d DVBS" on second front end then after 5-10 seconds w_scan on first front end then after 5-10 seconds w_scan on second w_scan run on both front ends simultaneously. > Use only one DVB adapter, not both.
