- NEW CONTROL COMMAND ("TM"): The TM command sets or reads the transmit metering mode on the LCD. TM0; sets the bar graph for SWR/RF, while TM1; sets the bar graph for CMP/ALC. The TX metering mode also determines what is read by the BG (bar graph read) command during transmit. With TM0 in effect, BG reads the power level. If TM1 is in effect, BG reads the ALC level.
