Radiogram Precedences and Handling Instructions
All messages handled by Amateur Radio should contain precedences -- that is, an evaluation of each message's importance, made by the originating station. A precedence is an "order of handling." There are four precedences in the Radiogram message form: Emergency, Priority (P), Welfare (W) and Routine (R), in that order of handling. When and as they appear on a net or any other kind of circuit, messages will be handled in this order.
EMERGENCY - Any message having life and death urgency to any person or group of persons, which is transmitted by Amateur Radio in the absence of regular commercial facilities. This includes official messages of welfare agencies during emergencies requesting supplies, materials or instructions vital to relief to stricken populace in emergency areas. During normal times, it will be very rare. On CW, RTTY, AMTOR and packet this designation will always be spelled out. When in doubt, do not use this designation.
PRIORITY (P) - Use abbreviation P on CW, RTTY, AMTOR and packet. This classification is for important messages having a specific time limit, official messages not covered in the emergency category, press dispatches and emergency-related traffic not of the utmost urgency.
WELFARE (W) - This classification, abbreviated as W on CW, RTTY, AMTOR and packet, refers to either an inquiry as to the health and welfare of an individual in the disaster area or an advisory from the disaster area that indicates all is well. Welfare traffic is handled only after all emergency and priority traffic is cleared. The Red Cross equivalent to an incoming Welfare message is DWI (Disaster Welfare Inquiry)
ROUTINE (R) - Most traffic in normal times will bear this designation. In disaster situations, traffic labeled Routine (R on CW, RTTY, AMTOR and packet) should be handled last, or not at all when circuits are busy with higher-precedence traffic.
The precedence will follow, but is not a part of the message number. For example, a message may begin with NR 207 R on CW, "Number Two Zero Seven, Routine" on phone.
Handling instructions (HX) are less used but quite useful in handling messages. They serve to convey any special instructions to handling and delivering operators. This "prosign," when used, is inserted in the message preamble between the precedence and the station of origin. Its use is optional with the originating stations, but once inserted is mandatory with all relaying stations.
The following definitions apply:
HXA - (Followed by number) Collect landline delivery authorized by addressee within X miles. (If no number, authorization is unlimited.)
HXB - (Followed by number) Cancel message if not delivered within X hours of filing time; service originating station.
HXC - Report date and time of delivery (TOD) to the originating station.
HXD - Report to originating station the identity of station from which received, plus date and time. Report identity of station to which relayed, plus date and time, or if delivered report date, time and method of delivery.
HXE - Delivering station get reply from addressee, originate message back.
HXF - (Followed by number.) Hold delivery until...(specific date).
HXG - Delivery by mail or landline toll call not required. If toll or other expense involved, cancel message and service originating station. Example: NR 207 R HXA50 W4MLE 12...(etc.).
If more than one HX prosign is used, they can be combined if no numbers are to be inserted, otherwise the HX should be repeated thus: NR 207 R HXAC W4MLE...(etc.). On phone, use phonetics for the letter or letters following the HX, to ensure accuracy.
