| Post subject: | USS Portland HYDRA System |
I forgot to post this last week when I was down at the port where the USS Portland was berthed for her commissioning ceremony. Here's the details on the HYDRA radio system on board: USS Portland (LPD-27) EDACS wide band System ID – 003 397.2625 LCN-3 397.6125 LCN-5 397.7625 LCN-6 399.1625 LCN-7 399.3125 LCN-8 399.5625 LCN-9 399.7625 LCN-10 Dockside security was using 395.2500, N293 and 398.6500, N293 for simplex communications. And a UHF air band beacon on 313.6250 MHz. It was a continuous AM carrier with Morse characters “A-I-A” being sent every 10 seconds. My assumption is since this vessel handles helicopters and tilt-rotor aircraft, a navigation/homing beacon to the ship would be a must. UPDATE - Just heard from a Navy vet that all ships have these UHF beacons. They normally don't leave them on in port. - CP |
