*- 100hz Tone Encode is required to open the repeater. While Full Tone Encode/Decode is not required on your end, it is highly recommended if you plan on running only FM or don’t have your radio in Yaesu’s Automatic Mode Select (AMS).  C4FM does not use squelch tones, using full tone E/D, your radio will ignore the C4FM digital transmissions. If you don’t, you will hear the C4FM data noise on your receiver and it can be very annoying.

** C4FM is the digital mode that Yaesu has selected for their radios. Although Yaesu is the only big three to use this mode, it is not truly proprietary. Some Ham Radio Hotspots like OpenSPOT support C4FM. There are two modes, Voice Wide (VW) and Digital Narrow (DN). DN supports transmission of your voice, but also call sign and location data in the transmission. VW only supports voice and call sign. W7GRA support both modes via AMS.

W7GRA RF Receive Probability Model


Radio propagation estimate was done by using the Radio Mobile Software. Radio Mobile was developed by VE2DBE. The data that was used to generate this picture is may not be 100% accurate and some of it was a guess. But this should give you a ruff estimate of this repeaters coverage. Remember this map only shows signal quality of how you would receive signals from W7GRA. Your signal quality into the repeater maybe different depending on your antenna and power output of your radio.
