In this segment of the video, the main points discussed are:
– Charging batteries: The Uniden scanner uses rechargeable NiCad batteries that last around 4 hours, while the Nisaku scanner lasts around 12 hours on receive. The Uniden requires power banks or additional batteries for extended use.
– Channels and scan speed: The Uniden has 500 channels and cycles through 9 channels per second on scan, compared to the Nisaku with 256 channels scanning at a slower speed of around 3-4 channels per second.
– Coverage: The Uniden has wider coverage, including CP frequencies and low band VHF, civil airband, and military airband (in AM mode). The Nisaku also covers civil airband and FM broadcast band but not military airband in AM mode.
– Antennas: The Uniden comes with a wideband rubber duck antenna, while the Nisaku has a VHF and UHF dual-band antenna, making it more effective for specific frequency bands.
– Additional features: The Uniden has Close Call functionality, which automatically tunes to strong local transmissions, while the Nisaku lacks this feature. Both scanners are PC programmable, with free and paid versions of software available.
– Pricing and functionality: The Uniden is priced at around £50 and the Nisaku at around £40, with the price difference reflecting the features and functionality each scanner offers. The Nisaku is considered a good introduction to radio scanning at a slower rate than the Uniden.
Overall, the segment provides a comparison of the Uniden and Nisaku scanners in terms of battery life, channels, scan speed, coverage, antennas, additional features, pricing, and functionality, helping viewers make an informed decision on choosing a budget radio scanner.
