Since both radios have the same identity, when some other vessel request a position from your vessel with the MMSI you have entered into the two radios on your vessel, both radios will receive the message and try to respond. Typically you can choose the method of replying to be automatic or manual, If your vessel has two DSC
radios, I would not set both radios to automatically reply to position poll
If you poll
the position of your own vessel with one of the radios on your vessel, the other radios on your vessel should reply. An MMSI identifies a vessel, not a radio.
Exactly how the particular radios you have will operate in the situation of receiving a position poll request from another radio with the same MMSI will be hard to predict. Perhaps you can call the manufacturer of the radios and ask their advice. Standard-Horizon generally has excellent customer support for their radio products.
