At 6:30PM EST I was scanning the UHF frequencies for activity on the GMRS frequencies because as of lately there seems to be an increase in traffic. I have my scanner set to low and high limits at 462.5625 up to 467.7125. After a couple of minutes I kept locking up on a carrier at 463.100. I decided to monitor that particular frequency and in time heard a man's voice giving a call sign. I was not familiar with this frequency so I looked it up online and found it to be for the International Frequency Coordination for Disaster Responders.
Upon further investigation I found that this is apparently the main frequency used by the United Nations. Apparently each country has their own set of 3 frequencies pairs (3 on VHF for distance and 3 on UHF for penetration through buildings). The call sign used was either JD3USA or JDBUSA.
It sounded like a standard radio check but I had know idea that frequency was even in use.
Has anyone else heard similar call signs on this frequency???
It was heard from Southeast PA.
