I'm headin down to Cuero, TX this weekend. I'll be coming down from tn and was wandering what DPS freqs to listen to when I get into Houston and Victoria. I'll have a Pro-96, just in case there digital.
155.46 - Simplex Base to 154.68 mobile
159.21 - Usually the 155.46 base will be repeated here. Mobile is 154.665 or 154.695
155.445 - duplex. Mobile is 154.665 or 154.695
All six frequencies will take you statewide. Usually THP will also talk with the local SO on the respective county freq where they're assigned or in some cases have a TG assigned on the trunked systems.
There was some talk last week of the Corpus area having digital working. Check out the database under Dept of Public Safety for those freq's. The digital system is also 2 meter.
Last weekend there was good skip coming from south TX on 155.46. I was picking it up on my Alinco rig with a 1/4 wave antenna in the garage.
