I hear MSHP aircraft on conventional analog 154.680 whenever they are in the Southwest Mo area.I live in N.W. Arkansas. I use a multi-band scanner base antenna in the attic and can receive MOSWIN from the Cassville tower (full scale) and Roaring River tower (3-4 bars) but the Pineville tower is usually not enough signal to lock (1-2 bars). I would have thought that Pineville would have been a reliable signal for me - not sure why not? I also have some kind of local interference that begins every day when it gets dark causing me to not be able to copy any MOSWIN until very early the next morning (can't figure out what is causing the desense). During that "blackout" time I have to rely on what VHF low band Troop D transmissions there are after dark. With all the new towers lately, VHF low band seems more reduced. I hear much more VHF low band Troop D at night than what I do during the day time now. During the day time, I hear some Troop D transmissions on VHF low band that I don't hear on MOSWIN on Cassville or Roaring River towers. I guess the Dispatchers must control when VHF low band transmissions are made instead of it being an automatic simulcast now. I sure miss the days of VHF low band only operations when there was a Carthage Troop D satellite headquaters on 42.12 MHz and where all Troop Headquaters used to run high power transmitters that you could hear all over the state as far as Kansas City. It seems like there was much more MP air units heard on VHF low band than what you hear now on MOSWIN. I also used to hear Willow Springs and Rolla Troops on VHF low band back in those days.
