Weren't police bands (previously) right about there? My license lapsed a few years back, but if memory serves, some people would do some minor surgery on their 2m radios so they could tune in to police bands just above 2m. I assume police all use some fancy digital microwave comms now.
- tlrobinson 12y ago"some people would do some minor surgery on their 2m radios so they could tune in to police bands just above 2m" Probably, but you could also just buy a police scanner from Radio Shack, or even a $10 TV tuner that can be used as an SDR: http://sdr.osmocom.org/trac/wiki/rtl-sdr http://sdr.osmocom.org/trac/wiki/rtl-sdr In fact I think those cheap Boafeng radios will even transmit on those frequencies. Of course that would be highly illegal. "fancy digital microwave comms now" Microwave radios are only really used for point-to-point links, as the shorter wavelengths require line-of-sight. They are using digital trunking systems (https://en.wikipedia.org/wiki/Trunked_radio_system https://en.wikipedia.org/wiki/Trunked_radio_system), and encryption in some cases.
- Florin_Andrei 12y agoMy Yaesu FT-817 transceiver has continuous, gapless tuning from the bottom of long-wave radio to the top of UHF - at least on the receiving side. I'm pretty sure there's a simple hack to also make it transmit on any arbitrary frequency - but that's illegal, of course. http://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCatID=102&encProdID=06014CD0AFA0702B25B12AB4DC9C0D27&DivisionID=65&isArchived=0 http://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCat...
