Brian McGinness, N3OC Contest Operating – M/S and M/2

Multi-single and Multi-two Operating Definitions Multi-single: One run radio & one multiplier radio Multiple operators OK to use packet Multi-two: Two run radios (no multiplier radio) Multiple Operators OK to use packet

Multi-single and Multi-two Operating Benefits Less operators than multi/multi Less equipment – easy to convert a single-op station Excellent training ground for new contesters Opportunity to always have a fresh operator on

Multi-single and Multi-two Operating Know the Rules – Multi/Single CQ Contests One run station with 10 minute QSY rule Multiplier station OK on one other band Packet spotting permitted Logs violating the above reclassified as multi/multi

Multi-single and Multi-two Operating Know the Rules – Multi-single ARRL HF Contests One run station limited to 6 band changes per hour No multiplier station allowed Packet spotting permitted Logs violating the above reclassified as multi/multi

Multi-single and Multi-two Operating Know the Rules – Multi/two CQWW & CQWW WPX Two run stations, no multiplier station allowed Maximum of 8 band changes per hour Packet spotting permitted Log must indicate which transmitter made the QSO Logs violating the above reclassified as multi/multi

Multi-single and Multi-two Operating Know the Rules – Multi/two ARRL HF Contests Two run stations limited to 6 band changes per hour Unused band changes can’t be given to other station No multiplier station allowed Packet spotting permitted Logs violating the above reclassified as multi/multi

Multi-single and Multi-two Operating Station Equipment Splitting a tribander stack for multi/two operation on two high bands using the AUX relay

Multi-single and Multi-two Operating Station Equipment Remote antenna switch, such as the WX0B six-pack

Multi-single and Multi-two Operating Station Equipment Bandpass filters will probably be needed

Multi-single and Multi-two Operating Operating Strategy – Multi/single Very similar to single op assisted but with addition of multiplier radio Run on the highest open band Don’t miss any multipliers on your two bands! Take advantage of fresh operators

Multi-single and Multi-two Operating Operating Strategy – Multi/single Consider the use of an additional interlocked radio on the run band

Multi-single and Multi-two Operating Operating Strategy – Multi/two Run on the highest two open bands Split the tribander stack until 10/15 are done Consider the use of two interlocked radios on the run bands Take advantage of fresh operators
