18 Νοε 2024 · It is not possible to receive digital TV audio with a scanner or AM/FM receiver. Before the transition from analog to digital TV in 2009, audio from analog TV stations could be received in wideband FM (WFM) mode.

8 Οκτ 2023 · I'm looking for a chart or other information that shows what the step sizes are in the different frequency ranges. I usually scan by 5khz steps in the 140, 150 & 160 ranges and 12.5khz for anything above 400 mhz. I'm probably missing some frequencies when I'm not scanning with the proper steps.
TV signals are broadcast on radio waves which typically operate below 1Ghz for TV aerial services and around 12Ghz for satellite TV services. But what does this mean? An Alternative current (AC) waveform you may already be familiar with.
29 Οκτ 2024 · As a basic definition, scanning involves listening (and, at times, looking) on frequencies just below, above and around the standard FM and TV broadcast bands. There are numerous services that use this spectrum - from police and fire, to the guy that picks up your garbage and lots in between.
A guide to selecting Radio Scanners; divides both new and used radio scanners into 6 categories, based on their specifications and features - e.g. analog trunking scanners, digital trunking scanners, etc; provides specifications on each model
28 Νοε 2008 · Currently, in order to simultaneously have an analog and digital signal, stations are actually operating on two different TV "channels". Once the analog transmitters are turned off, they have a choice of keeping their new digital frequencies, or going back to their original analog frequencies (as long as they aren't above Ch. 51).
19 Φεβ 2007 · Most TV antennas are of a log-periodic design to cover 54 to 220 MHz on VHF and 470 to 790 or so on UHF. There is no reason they won't work for scanners. You will lose as much as 15-20 db, especially on the higher frequencies, by having the antenna horizontal instead of vertical which will noticeably affect weak signals.
