Hints and Tips
Using filter Digits In Selcall.
Where the DRC-1 is deployed on commercial (shared) radio frequencies, it is advisable to use
fixed digits as part of the selcall string. The fixed digits act as a filter for the decoding system.
For example, if the selcall pattern within the DRC-1 is set to ###**, then the DRC-1 will
decode any five digit string which is received as 3 digits of ID plus two status digits. If the
selcall string is set to 8##**, then, only strings which begin with an 8 will be decoded.
