We are planning a three day event in Asheboro, NC at Gray Owl with all the Radio-O formats, 80m, 2m, Sprint & FoxOring. The terrain at Gray Owl is very similar to Morrow Mountain where the US Champs are being held

**Note that while Sprint will interfeer with FoxO because they use the same frequencies it is not the other way around because the FoxO transmissions won’t reach the Sprint areas. That said, Sprint isn’t using 3.54 MHz, so there is a short 2.9 FoxO course using only those controls that can be done while the Sprint course is on.

80m: We will be using the OK2BWN 80m Transmitters at 3W which is likely the same transmitters that will be used at the Worlds. The course will fit on Letter size paper at 1:10,000 (5 foxes Streight Line=SL=5.9k Efective Length=EL=7.6; 4Foxes SL=4.1  EL=5.3; 3 foxes SL=3.1k EF=4k)

2m: We will use Charles’ 2m transmitters. Definitely these will be used for the US Champs. The course will fit on Letter size paper at 1:10,000 (5 foxes SL=5.8k EL=7.4k; 4 foxes SL=4.6  EL=6.1; 3 foxes SL=3.5k EF=4.4k) I have done my best to locate the transmitters where there will be multiple reflections so you can get good practice before the US Champs and Worlds.

Sprint: We will use OK2BWN 30mW transmitters on bamboo poles. The sprint will fit within the 300m exclusion zone for the other courses. The sprint is now a full 12 fox sprint, and is designed so it can be run as one full sprint SL=2.3k or each half separately. Slow SL=1.1k  Fast SL=1.2 The Sprint will run continuously from 3pm on Saturday until 11am on Sunday, so if you are staying over you can do the sprint as a night course. (The finish beacon and the spectator beacon are one in the same.)

FoxOring: (SL=5.5k EL-7k; Short SL=3.6 EL=4.8) Charles’ FoxO transmitters. Definitely these will be used for the US Champs. The course will fit on Letter size paper at 1:10,000. Since the Classic courses are all in the same area as the FoxO, I recommend that you do a classic course before you do the FoxO.
