TM 1-1520-240-10 3-2-4 3-2-6. Word-of-Day. The WOD programs the frequency hopping rate and pat- tern. Without it, the radio cannot function in the AJ mode. A WOD is made up of a maximum of six WOD segments plus a date code. The Have Quick II radios are capable of storing up to six WODs, thus allowing for multi-day use of the radio set. This technique is known as multiple word-of-day (MWOD) loading. The basic have QUICK radio allows loading a single WOD, in volatile memory. Four operating modes are used within the radio set to initiate various Have Quick (HQ) programing functions. They are accessed via preset 20 with the frequencies listed in Table 3-2-1. The functions are Operate/verify, MWOD load, MWOD erase, and Frequency Managed Training (FMT) frequency load. 1. Glide slope 2. Radar warning 3. HF ARC-220 antenna 4. VHF navigation 5.
