The default is band A. “”indicates the current data band.Note:In Menu 601, the selection switches among A-BAND, B-BAND, TX:A-BAND RX:B-BAND, and RX:A-BAND TX:B-BAND.Select TX:A-BAND RX:B-BAND or RX:A-BAND TX:B-BAND ifAPRS networks which use two separate frequencies becomeavailable in the future.nPacket Transfer Rate The default APRS packet transfer rate set on the built-in TNC is 1200 bps which is the standard among thecurrent APRS networks. If APRS networks which use9600 bps transfer rate become available in the future,select “9600 bps”nDCD Sense You can also select the method for inhibiting the built-inTNC from transmitting. Select one of the two methods.The default is “D or Rxd Band”.[D or Rxd Band]:The TNC does not transmit when signalsare present on the data band () or RX data band ()[Both Band]:The TNC does not transmit when signals arepresent on band A or B.nTxdelay xDELAy>This function allows you to set a transmission delaytime between transmitting the APRS data andtransmitting a flag code prior to the APRS data.
