Hey all,
We are looking to buy a communication system for a newly formed rescue team.
I have seen some options:
1. Wireless: System Nicola Cave Radio, [Micro] HeyPhone and Cave link.
2. Wired phones
3. APRS relay
Our caves are not so deep (up to ~200m) and not so long (up to ~10 km) but the rock can be Limestone, Sandstone or salt.
Our considerations are:
1. Cost, unfortunately we don't have a lot of money.
2. Availability, we are looking for a device that can be purchased from the manufacturer or self-assembled but the diagrams and parts are available for purchase
3. Simplicity and reliability (a system that has proven itself in the field and not something experimental)
I would appreciate any advice based on your experience.
TIA
