Thanks for your long explanation. In that case, then I think it must be due to the circuitry. The frequency distribution & bandwidth are the same for FRS & GMRS. Only the allowable power output is different. FRS channels are limited to 0.5W. GMRS channels can go beyond 0.5W, so maybe that has something to do with the way the circuit works on your sets. I previously tried on many other sets and I cannot find those difference.jwkong wrote:hi bro,
i have tried all the 22 channel in the FRS/GMRS radio.
from my testing all the channel is empty and clear of usage.
another funny thing is that using all 22 channel i have tested and found out that FRS channel 8 - 14 have a very big difference in terms of sound and clear voice.
when i am using all the GMRS channel 1-7 and 15-22 there is so many static.
this is why i feel very weird.
they say GMRS is longer... but my GMRS is worst than FRS.
The frequency difference is only 467MHZ and 462MHZ... not much difference in terms of disturbing other legal frequency cos the frq only varies in 5MHZ which is 1 wideband...
Anyone tested their FRS/GMRS walkie talkie before for longest and clearest channel?
Yes, there is a difference in terms of disturbing other legal frequency users. For example, if you go to different parts of Malaysia, you will hear some radio-telephone traffic on one or two of the channels. Different channels in different parts of the country. However, that was a few years ago. I think, as the country gets more wired, there will be less use of the radio-telephone channels.
