Hi. While not a 'Please fix-it' question, I'm hoping that somebody in the communications field can offer advice. I've come across a fairly simple-to-construct electronics project for a 6 watt FM transmitter. If allowed, I plan to build two of these to use as outdoor / hiking walkie talkies on the BCB band 88-108 MHz. Approximately how far would 6 W transmit, and would I need a license, if even allowed on this frequency range? The text states 2m950mm wire antenna which I calculate at 3/4 wavelength. If portable, I plan to use 1/4 wavelength of 98 MHz, mentally calculate about 70-71 cm. Thanks, Clive.
I would strongly suggest that you investigate the rules about transmitting in that country. 88-108 in the US is reserved for commercial broadcasting (FM). Are you a US citizen? If so, I would recommend that you get your Amateur Radio license in the US which is usable in most other countries. Then you are legal. (But only in the frequencies for that country.)
Testimonial: "Thanks for the reply. Since posting, I've researched a bit further (RSA). It turns out these FM microphones at only a few mW range about 10ft. 6W _could_ reach 5Km or so, licence required, but ******* on FM-BCB."

plse contact a service team,

SOURCE: walkie talkie wont communicate
um if it dont transmit then take it apart if you know how to or
let me see it
i can fix eny walkie talkie
SOURCE: communication not good &battery cannot charge
If your area is big or has a lot of concrete, then you will need more then just a few cheap radios from thailand, Given range info from broshure is always meant above flat area - not inside building
SOURCE: Is Bell South walkie talkie compatiable with other
Some number their channels differently, but all FRS/GMRS radios operate in the same mode and will have at least some frequencies in common. Check the channel/frequency lists for both radios and you'll be able to talk to each other.
