Bob,

 

You need to program your MMSI (an identifier you get when you register the 
radio). In Canada (and I bet in the US) in order to operate a DSC radio you are 
required to have the DSC endorsed radio operator’s licence. 

 

Without the MMSI your DSC function does not work - it is like a phone without 
an assigned number. If I recall correctly, it is illegal to use the radio 
without registering it and acquiring the MMSI number. And if you don’t program 
the MMSI, the radio would probably not work at all (it should prompt you 
constantly to enter that number).

 

In order to use the point to point transmission (not any of the Distress or 
Urgency calls) you have to know the other party’s MMSI. Preferably, you want to 
have it programmed into your radio (so you can select it, like from a 
“Contacts” list in your phone).

 

Ch. 70 is used SOLELY for digital handshake between the DSC radios. Using that 
channel for any conversations is prohibited. 

 

I am afraid that you won’t be able to make the DSC call to the passing barges 
unless you know their MMSI (or can look it up).

 

Good luck

Subject: Stus-List Testing DSC

 

Today I received my first grown-up radio, a Standard Horizon GX2200.

DSC looks like a very nice technology but I am wondering how to test/learn it 
without triggering a bunch of false alarms or general chaos.

I'm docked in a backwater, but there is occasional barge traffic that probably 
has AIS transmitters. 

I'd like to verify that my new radio can easily communicate (via channel 70?) 
with the barges as they pass by.

Maybe I need to read the fine manual again but am wondering if anyone else has 
done this exercise and if there are any tips or gotchas.

Many thanks in advance,

--Bob M
