This event takes place this coming Saturday May 10. Attached is a somewhat modified version (to make it easier to read when printed) of the Stations, times and frequencies listed at the ANNUAL ARMED FORCES DAY CROSSBAND TEST (10 May 2025) website - https://www.dodmars.org/mars-comex-information-website/armed-forces-day This is a fun and somewhat challenging event because we have to Listen to frequencies (MARS) we typically do not utilize habitually to hear what Amateur Radio Frequency each Station is monitoring in order to make contact. Then operate in “Split” mode (more information is below). And yes, many of you are very familiar with “Split”; however, many new Operators are not. This is called a CROSSBAND event because the Military Stations will be transmitting on Military Auxiliary Radio Service (MARS) frequencies and will announce what Ham frequency they are monitoring. The Ham objective is to set up your HF radio to Receive on the MARS frequency and listen for the announcement telling you what Ham frequency that Station is monitoring. Then transmit on that Ham frequency to contact that station to get on their Log Book. This event offers QSL Cards for Hams that make contacts with the Military Stations during this event (see that info at the bottom of the Word document). If you do not know how to operate “Split”, here is a link to a short 4-Minute YouTube video that explains how to configure an HF radio for Split Mode. In this case he explains specifically how to configure the ICOM IC-7300 for Split operations. However, most HF radios use virtually the same steps but obviously with different buttons to push. I highly advise you to ignore the “slightly off-frequency” trick he suggests for breaking pileups. IMHO, that is not good Operator Practice and the strategy just doesn’t make sense in the first place. - https://www.youtube.com/watch?v=C19DuR4ywxo&t=242s Let me know if you have any questions. If you have a Yaesu FT-991A, below my signature are the “Split” instructions that Jason (N5TXL) provided a couple of years ago for that radio. 73, Bob – KG5SQJ
