General Information

This wiki will be used to compile information on the system that is unconfirmed, such as licensed frequencies around the service area of South and Central Texas. Some sites may actually belong to S&P System 68 which is geared more toward Metro San Antonio and Austin and the 35 corridor in between.

When searching for licenses, they may show up under BNS Enterprises, Inc (FRN 0023754229) or Nathan Sherman Enterprises, Inc. dba S & P Communications (FRN 0001690155). All sites swap between their two control channels systemwide between 12:50 and 1:15 AM nightly.

Although Nexedge 4800 systems have a user specified band plan, which can be frustrating for hobbyists, system 303 appears to have a fairly straight forward layout when seen side by side with it's sister system, S&P 68. Based off of somewhat extensive monitoring, the band plan so far is as follows:

Band Plan System 303
CH 000 451.01250 CH 321 453.01875 6.25 kHz
CH 322 460.65625 CH 924 464.41875 6.25 kHz
CH 925 454.00000 CH 980 454.68750 12.5 kHz
CH 981 464.42500 CH 1027 464.98750 12.5 kHz*
  • we can't be sure of the final bandplan line until we have confirmed what CH 999 is by hearing it on the air. It shows up as a CC on just about every DSD+ site monitoring session.

Sites

North Central San Antonio (1)

WQUD572

23000 NW Military Hwy

  • CH 012 451.08750 - Confirmed CC through monitoring
  • CH 015 451.10625 - Confirmed CC through monitoring
  • CH 018 451.12500 - Confirmed VC through monitoring

Unknown Location (2)

  • CH 118 451.75000 - Confirmed CC through DSD+ neighbor data(no longer in rotation)
  • CH 927 454.02500 - Confirmed CC through DSD+ neighbor data
  • CH 977 454.65000 - Confirmed CC through DSD+ neighbor data

This site is currently unknown as to where it resides. However, the only site licensed to BNS or S&P in the state with 451.7500 as a repeater is Robstown, Nueces County. That license is WPRU864. Other channels licensed at Robstown, all for NXDN, are:

  • 451.00625 (Not known to be in bandplan yet)
  • 451.01250 (CH 000)
  • 451.21250 (CH 032)
  • 451.26875 (CH 041)
  • 462.53750 (CH 623)
  • 462.73750 (CH 655)

These should be plugged in and monitored along with the two 454.xxx part 22 frequencies to confirm if Robstown is indeed site 2.
