[Scan-DC] Metro: DC Fire and EMS radio encryption blamed for failure in de - DC News FOX 5 DC WTTG

[Joel Kahn]

Not at all, the leaky line repeaters are used to carry all comms on the repaeted frequencies.  Since WMATA went to the TRS I do not know if they upgraded the repeated frequencies from 160s to 480s.  I know that when I rode the system in November, my scanner was picking up the OPs and MetroPD on the old 160 frequencies just fine, as was DCFD on 800Mhz system the entire time I was underground.

I would suspect, like has been mentioned here, that the 700MHz channels have not been added to the repeater equipment, not that the encryption, per se, was the culprit.  If it was the encrypted fireground channels, then they should still have been able to communicate on 01 and 02 that are not encrypted.  The radios did not work at all underground.

If that were the case, WMATA police and the train operators would not 
have been able to communicate with their dispatchers.
Nobody has claimed that problem occurred.
