A total power radiometer (aka crystal video) is going to have a tough time in this sort of environment, unless you use very long averaging intervals and do some strong signal excision ___ 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.

[time-nuts] Detecting GPS and other jammers
We make & sell the jammer detectors as a part of our contraband cell phone detector products. The jammers are so common now flooding in that we have a stealth GPS tracker so that drivers of company trucks that have radios in them aren't aware of the fact that they are being monitored BUT if they find out we also sell the detectors. They aren't expensive either. www.CellBusted.com Robert L.
