      found out the message problem all has to do with deviation problems, I can
      talk to gillette but none of my stuff can get into sheridan where n7hri is
      and we are trying to work on this. the digi systems in sheridan are being
      ran by motorola radios and I cant seem to get the right deviation to drive
      the sound on them. there is only 2 stations that can drive them right.I'm
      using a maha rexon rl-112 that is fully open for all freq I don’t know about
      the type of cable, it has the mic input. it’s the same cable at byonics that’s
      the HT1C cable but without the power. you have this right about me getting
      batty. there is something intermittent issue. I was able to get your message
      on my gps. I don’t know what I'm doing here. I wish know more about solder
      and stuff, I'm just a dumb little truck driver out here in lonely wyoming
      lol.
