An organisation I volunteer for is in the process of replacing their current radio systems with a new one. I was only ever in the OTC, but secretly found some of the signals stuff quite interesting. I'm looking for a bit of advice on where I can find literature on how we can make the most of our new system. I've not got all the details yet, but it's on the UHF band and has the capability for using both analogue and digital. Within the digital capabilities I believe we can have anywhere between 32 and 160 channels. There are also GPS units built in to the radios to provide real-time updates of the radio whereabouts to the base unit - as well as the capability for the base unit to control the mobile units (turn mic off/on etc). Now, to me digital sounds like a fecking nightmare, but only because I remember staff complaining about BOWMAN a few years ago and I'm not normally keen on the "high-tech" solution. Then again, better than the 349s which couldn't communicate further than we could shout... So, what I think I need to know is how to make the most of the ranges on the base unit, repeaters and handheld units - through use of antenna, placement and anything else that might be useful. The radios have to perform decently as two way radios through heavy woodland with medium to steep relief, which I know is not ideal. I'm really rather a novice at this, but no-one else within the area has specific signals knowledge, so I thought I'd try and pick up some info the help out.
