VHF DSC Radio Check
I just installed a Standard Horizon HX850S handheld VHF radio (with GPS) as
a backup for our 25 watt fixed VHF. I checked out the VHF transmit and receive function with a couple of radio check calls to local boaters and reception was 5 by 5. (Actually the reception was better than that on my fixed VHF). Additionally, I wanted to check the DSC functionality of the radio by placing a ROUTINE call to the local Coast Guard's MMSI number. However, after transmitting the signal, there was no "acknowledgement" for 5 minutes and I then cancelled the call. Tried it again later with a routine transmission to the "Rescue 21" MMSI number - again no acknowledgement. I was transmitting on the HI setting (6 watts) and was in sight of the local CG building - so the transmission "should have" triggered the automatic response. The HX850S is brand new out of a sealed box so I doubt it is defective... but one never knows. I really would like to be sure that I can rely on the unit for a distress call - but of course I won't know that until I am in an distress situation and push "the red button"! Any ideas or suggestions on how to check the DSC funtionality? |
