I dont think very many services use 2-ways in there trucks like (haliburton, schlumberger...), but i know most your tank trucks and companies like that use them.
Schlumberger just went to 2-ways in oklahoma about 3 years ago
Hmmm they must have gone another route for a while maybe cellphone's or nextel type things. Must have not worked out that well especially if they are in remote rural areas.
Back in the 1980's they used 47.68 some. What is Schlumberger using now freq wise?
