Hey guys, I need your help on this one.
Me and my team are a water rescue and assistance group that operates out of our marina, but we are not affiliated with the Canadian Coast Gard (CCG), we operate with the city. We are equipped with HX210 standard horizon radios, and they have worked really well, until recently.
All of our radios are kept on Dual watch, our main channel is channel 71, and we dual watch channel 16 for emergency traffic and navigational warnings. However, I recently discovered what might be a bug, though Im not sure if its a feature or not. My and my colleague were talking on 71, but when he responded, my radio flipped to channel 16 and it was him talking. I advised him of the situation, still on 71, and he responded (on 71) that he didnt touch anything except his ptt. When I responded, my radio flipped to 16 and my collegue also heard my communication on channel 16, altrought I only touched my ptt and nothing else. I also made sure before transmitting that my radio was on channel 71, and nobody was talking on 16, wich was the case. Soon as I hit the ptt, it switched to 16.
I then grabbed a few radios and made some tests, transmiting on channel 71 with 2 radios. After 2 or 3 communication, one radio switched to 16. The other radio (wiched I turned off Dual watch), did not recive the message on 71, but the other radio on 16 (no DW) did. That radio (on 16) did no receive any communications prior to me talking. Plus, this was a rainy day with almost no boats on the water, channel 16 was very quiet.
Because these are handheld radios, I doubt the CCG ever heard anything, they also never responded and never contacted our marina to tell us to switch channels.
I find this very weird and a pretty big problem to the safety of all on the water using channel 16… anybody have an explanation or a way to fix this (besides turning off DW).
Thanks in advance !
