When I was trucking I used to keep the repeaters in the area I was going to or in in my 2M and latter 2M/440 rig. Most of the time they were dead. I made many contacts on 146.520MHz with locals and other travelers. I used to pick up the mic and ID every 10 or 15 minutes. I talked to allot of people that way. When I got my Yaesu FT-7800 it had 1000 memories channels so I also purchased the ARRL's Repeater Directory and programming software and when planning my next trip I could set the rig up to have all the repeaters on my route ready to go. I still worked more stations on 146.520. I had the CB too. There was so much trash (people) and garbage (noise) on that thing I kept the volume up in case somebody close wanted to warn me of impending doom (Accident, weather, Kojak with a Kodak etc.) but kept the RF Gain all the way down. I could only hear those who were very close.
