Later I bought an operator assist radio phone, I kinda liked that. $28. a month if I did not have out of area roaming charges.
The handheld walkie talkie had a 60 - 80 mile range, with the optional booster in the truck, and sitting on a hill - over 200 miles was "possible" ...
Days long gone....
I am curious the frequency band?
It can be assumed a HT is 2w maybe up to 5w but that signal stuffed through a horrible dubber duck antenna but the tower side will have a good antenna and a nice on band LNA at the antenna before sending the signal to the actual receiver. Since we get diminishing returns form EEIRP especially when compensating for crap antenna I am guessing anywhere form 50-200w at the truck, though I once saw an ambulance with a 1500w power amp at ~150mhz, the thing would blow out the fire station PBX if the radio was keyed inside the station(I recall ~3m from antenna to PBX).
I love the topic and hope I get a response but I feel like I am derailing the thread.
