Many oil field companies must use cell phones or nextel. There is some kind of oilfield fluid hauling company on a repeater in the El Reno, Geary area judging from the locations I hear. it is on 462.025.Im from el reno but im looking for all across oklahoma.
Ive got a few from when i traveled and reprogrammed radios for other companies but just wondering what any body had.
Most your oilfield companies wont have registered licenses plus i dont know how to get the tone once i get the freq.
Yes Halliburton was big into low band back then 47.440 was licensed to multiple locations in OK. The longer range of low band covered a lot of the hard to get to places better than higher freqs. 300 watts at 300 ft and a 110 watt mobile.Remember the old Halliburton Ford Crown VIctorias with the red and grey color scheme. They were based near 50 Penn Place and they all had the 9' quarter wave whip like was used on the old OHP vehicles. I'm sure it was VHF-low. Most oil developers at the time also had the VHF based mobile telephone systems. Remember, "Mobile Operator, this is 10159, please connect me to ....." Then came the trunk phone at $1.00 per minute. I joined the fray at 60 cents per minute and have never stopped.
Have you seen any 2 way antennas on their vehicles? That might give you an idea of a frequency range to check out.So, what's haliburton using now? I'm not far from their Burns Flat yard and I'd listen in if I knew the freq. I have several friends who used to work for them.
That base station is in Maysville and that dispatcher is the same fellow that's been on the radio for years.Back in the 80's many oil cos were on Lowband. Not so much any more they've gone elsewhere on the bands. However Shebester-Bechtel in the Lindsay area appears to still have a license for 47.520 and I heard some traffic on that frequency today.
