I have a thunderbolt acquired from TAPR. Almost every time the number of satellites change, there is an abrupt change in the DAC voltage – as high as 1 mv, sometimes. See www.decampos.net\LH\LH1<http://www.decampos.net/LH/LH1>.png - a graph with time constant 200 and Damping 4. Using much higher values improve the situation, as can be seen in www.decampos.net\LH\LH2.png<http://www.decampos.net/LH/LH2.png>, time constant 1000 and damping 100 (note the change in the DAC scale), but the jumps are still present.
Is this normal, or I have a defective unit? The antenna is located in a window, with several buildings nearby, so the change in the number of satellites is frequent. -- ------------------------------------ gera...@decampos.net _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
