Terrible compared to some, yes - but in practical use, they're OK. Most of the issues are not really relevant here. If he has programmed in frequencies and is not hearing anything, it will be basic.
1. It could be faulty, but that would be rare.
2. The frequencies entered may not be in use.
3. They may be legitimate frequencies, but he is simply too far away.
4. The frequencies may simply have little or no traffic.
5. they have been entered incorrectly.
Split frequencies are sometimes entered the wrong way around - so your radio is listening to the mobiles, NOT, the base.
Range is so often misunderstood.
If I enter a frequency for my own repeater, in my home it works fine. in my office, half a mile away, it's very, very weak. The office is in the harbour, surrounded on three sides by buildings. My office can hear the airfield 8 miles away! Just geography and topology.
I'm a Brit, so your zip code in google earth shows a very rural area. Small towns with lots of countryside between them. If i look at a 10 mile circle and move it around, lots of places have nobody in them!
Silly question, but what kinds of frequencies are you entering and how far away from you are they?
