Hello Chris, Do all of your transponders have such issue or only some special transponders? Could you list the parameters for them? for example, dvb-s or dvb-s2 type, frequency, symbol rate. The dvbsky.net firmware "dvb-fe-ds3103.fw" is version 3.7. Annti uses the firmware "dvb-demod-m88ds3103.fw", which is version 3.B. But we test both firmwares work well. You can change one to the other's file name for check.
