Kansas City 2 St. Louis

Does anybody know what kind of activity and reception you get when driving from KC to St.Louis on I-70? And also south of St. Louis on I-55 south to Cape Girardeau. As far as Highway Patrol are concerned mainly. Just curious.

KC to Cape

Try the following dispatch channels:

42.380 Troop A (Lee's Summit)
42.120 Troop F (Jefferson City)
42.060 Troop B (Macon)
42.380 Troop C Rural (Kirkwood)
42.060 Troop C Metro (Kirkwood)
42.120 Troop C South (Kirkwood)
42.060 Troop E West (Poplar Bluff)

Good luck!

My 2 cents

Hi Mark,

I have very good luck monitoring the highway patrol. If you want to monitor them along the I -70 route then you also need the UHF frequencies that they operate also in addition to the above post.

There are several UHF Freqs that the Highway patrol units use. These frequencies can be found on this site. The highway Patrol extenders are also using the ham band at 148.000.

I use dedicated antennas for UHF and Lo-band and 800mhz and I have no problems monitoring anyone on the way to St. Louis.

Good coax with a proper receiving antenna is the key to sucessful monitoring period!

KC 2 ST Louis to Cape

Actually, the extender frequency is 148.600 (and it's not a ham frequency--it's on loan from the national guard) and HP is using in conjunction with a frequency sharing agreement.

Repeaters are beamed from the site on UHF to the respective Troop HQ, they are not omni-directional like most people think--and some, like the Odessa repeater, pipe audio back to the troop by telephone line. You might be able to hear the following on your trip for short durations while within the beamwidth:

Boonville (Troop F) 456.275 103.5 Hz
Mexico (Troop F) 456.525 103.5 Hz

Warrenton (Troop C) 456.575 151.4 Hz
Potosi (Troop C) 456.625 151.4 Hz
Knob Lick (Troop C) 456.175 151.4 Hz

Knob Lick (Troop E) 456.525 123.0 Hz

Remember, also, that Troop C is using horizontal polarization on their repeaters, so a vertical polarized mobile antenna will not work as well with cross-polarization loss . . .
