Quick Q about radio signals in current climate

[NorthernRaider]

Thanks chaps I appreciate your information and advice, I dont want to sound negative or troublesome but the more I learn about radios and the various frequencies / systems the more I believe they wont be of any use to my group, They are just too limited and ineffective for practical use. At best on a clear day with line of site you still require LUCK to be on your side to be guarenteed any decent range from a handheld set, and in a normal urban or hilly, or wooded environment and / or day days with rain or low cloud their use is apparently even more limited.

I think RV points and couriers will be better suited to my own groups needs and the topograpghy in Co Durham.
