193 - DTV - The P25 Killer ?

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

In today’s podcast, I am going to talk about P25 digital technologies on the UHF T-band and how this decision has caused many problems for P25 Trunked Systems.

👉 What You Need To Know

• In the early 1970s, the FCC permitted eleven major cities of the US to use 470 to 512 MHz as additional public safety frequencies, and these were part of the UHF T band.
• The original UHF band was just 450 to 470 MHz
• UHF-T band was reserved for two-way radio around a 50 mile radius from each city.
• Issues arise when we have E-Skip and Tropo Ducting in the UHF spectrum.
• Digital TV from out of the market is causing problems on the digital spectrum in the UHF T band.
