communication solution for a long and deep cave
« on: September 20, 2020, 09:21:41 am »
hi every one this is my firts post in this forum so if ım in wrong topic to ask this please guide me. we used pocket field phones https://cavephone.blogspot.com/  with cheap indoor telephone cable  for 3-4 for years in this cave and in our last activiy phone cable broke up. so we think to change the way we contact ı look for some heavy duty army cables but thay are expensive due to exchange rate .is there any low cost durable cables you can suggest?

and also ı wondered how is the performance of this sound powered phones for a 5km long 1300m deep cave?

ı also look for some cave radios but thay are so expencive too and dıy projetcs like nikola and heyphone are hard to build for me. ones someone told me that there is also cavelinks for rent ı look to their website but havent seen any think about that and also price (ı think they want me to mail them for there infos). and is there any cave radio list with prices on it ?
