Depends on the repeater and the number of programmable memory locations that the manufacturer has provided, as part of the design. Also, older systems used CTCSS only. More modern systems can use CTCSS or DCS and the number of code possibilities and combinations for input and output is quite extensive.

Data supplied by our colleagues at RadioReference -

Common CTCSS code list: http://wiki.radioref..._Squelch_System

 

Common DCS code list: http://wiki.radioref...m/index.php/DCS

Thanks the reason i ask is that a local repeater (freq not listed due to privacy)has a total of 8 PL tones assigned is that going overboard just a bit?

And i think these are CTCSS tones they are using

Some repeater owners use several input and output tones or DCS codes for 'special purposes'.  Example - An owner allows 'travelers' to use the system.  However, the owner's FAMILY has a different access and output code so their family conversations are not necessarily heard by other users. There are also options built into some repeaters to set up a priority memory.  If a non priority conversation is taking place and the owner needs to use the repeater immediately, the owner's set of codes will stop the non priority conversation and allow the priority conversation to take place.  Most MOBILE radios are programmed to go into CSQ mode when the mic is removed from the mic holder, so this would tell the non priority users that the repeater is being used for a priority communication.

 

Each manufacturer has their own set of operating protocols and comparing features before buying equipment is always a good idea.

I'd also like to mention that a few manufacturers of communications equipment have introduced "non standard" CTCSS and DCS codes. This is 'sometimes' used by dealers to keep off-brand equipment from interacting with their own brand.

Our BridgeCom has 24 selectable tones, of course that depends on how you set it up.  Unfortunately we are unable to operate as ORI due to illegal operators using the travel tone, in our area.

CAN'T YOU IN THAT CASE DISCONNECT YOUR TRAVEL TONE AND ANNOUNCE TO THOSE ILLEGAL USERS THAT YOU'RE BENIG REPORTED TO THE FCC?

In theory, yes, but in addition to using the travel tone they are also operating in a non compliant mode. simplex on the repeater input frequency. To make an announcement to said illegal operators, requires shutting down the repeater and attaching mobile radio to the antenna and TX'ing on 467 or reversing the duplexor and running the repeater in reverse. I have made several announcements using 25 watt's. no response. So we have disabled the travel tone indefinitely.
