Who on earth is still using VHF radio in a world where countries are even getting rid of FM frequencies for ordinary radio broadcasts? And it cost 770 million shillings? Why didn't they advertise for a free used one? I know places with whole systems that were never taken out of the boxes when the mobile phone came! These contraptions do not work, are open to eavesdropping and in fact anybody with a handset can scan and detect your frequency (if he does not already know it). He can then simply interfere with it by pressing the handset on and placing it near a radio playing continuous music.
I would understand if they had used the money to pay Safaricom and other mobile companies to allow them dedicated lines to freely use their masts. One can make a lot of calls for 770 million!
However since it is a small area, they could have explored setting up a mobile phone network dedicated to them. Al though that makes it easy for poachers to sabotage.
