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

• Saturday May 10, 2025
  • 80m – 9am – 5pm
  • **FoxO – 9am – 5pm
  • Sprint – 3pm – til…
  • Pizza Dinner – 5pm
• Sunday, May 11, 2025
  • 2m – 9am – 5pm
  • Sprint – …from – 11am
  • **FoxO – 9am – 5pm
• Monday, May 12, 2025
  • FoxO – 9am – 5pm

**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)

80m Classic(Jiri Foxes)	80m Foxes	3.58 MHz	3 W	“MOx”
	80m Beacon	3.60 MHz	3 W	“MO”

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.

2m Classic (Charles Foxes)	2m Foxes	144.50 MHz	1 W	“MOx”
	2m Beacon	145.55 MHz	1 W	“MO”

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.)

Sprint (Jiri Foxes / Bamboo Poles)	Sprint (Slow)	3.52 MHz	30mW	“Mx”
	Spectator (Beacon)	3.60 MHz	30mW Orange stripes	“S”
	Fast Sprint	3.56 MHz	30mW Pink Stripes	“Ox”
	Beacon	3.60 MHz	3W	“MO”

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.

Foxoring (Charles Foxes)	Foxoring Foxes	3.52 MHz	10 mW	“MOx”
		3.54 MHz	10 mW	“MOy”
		3.56 MHz	10 mW	“MOz”
	Foxoring Beacon	3.60 MHz	3 W	“MOz”

Pizza Dinner: We will host a pizza dinner Saturday afternoon.

The Start and Finish for all the formats will be close to the house, registration and gathering area.

Camping and Hotels: Camping is available on our property as well as nearby comercial campgrounds. There are also a variety of Hotels in the area.

Location & Directions: 1725 Gray Owl Road, Asheboro, NC. (35.634843, -79.881873) There is a control on our mailbox at the intersection of Hopewell Friends and Gray Owl Road. Drive 1/4 mile on Gray Owl and take the first left turn onto our driveway. Drive 1/4 mile to the turnaround, turn around and park only on the right side (east side) of the driveway as you are heading back out. Do not drive on the grass at all! Do not park in the turnaround!

We are well into the peak of pollen season here in North Carolina, so clouds of the yellow stuff were blowing out of the trees and many runners emerged from the largely pine forest covered in it. But the temperatures were perfect for running, the forecasted rain held off, and the woods were still open […]

Half-Life Score-O

Join us for a Score-O event at the New Hope Overlook section of Jordan Lake on Sunday March 30. In this event, your goal is to collect as many points as possible within the allotted time. There is no set route—you can visit the controls in any order you choose.

REGISTRATION IS CLOSED

Special Twist: “Half-Life” Controls
Some controls on the course will be designated as “half-life” controls, meaning their point values will decrease over time. To maximize your score, visit these controls as quickly as possible. These will be denoted as “1/2” on the control description

Event Timing and Rules

• Map Handout starts at 10:00 and you can use as much time as you want to plan your route
• Start Time: Anytime after 10:00 AM (but you must finish by 2:00)
• Time Limit: You have 2 hours from your start time or until 2:00 PM, whichever comes first.
• Maps will be printed at 1:10000 on an 11×17 (tabloid) sheet. These can be folded in half to fit in a standard map cover

Late Penalty
If you return after your 2-hour limit or after 2:00 PM, you will be penalized 3 points per minute, beginning immediately after the deadline.

Control pickup will begin promptly at 2:00, and help with pickup would be appreciated.

Registration will close at 5pm Friday, March 28. 10am Saturday March 29

There is no entrance fee required at the park.

2M Radio-O

Alongside the regular score orienteering course, BOK is offering a 2m Classic radio orienteering course. This course is meant for experienced radio orienteers and beginner instruction will not be available.

The courses will open soon after 10am to keep time with the score-O and we need you to be done by 2pm so that pickup can begin.

This is a classic 2m course with the goal of making it as much like a championship course as the narrowness of New Hope Overlook allows. The exclusion zone will be 600m instead of the normal 750m, but all controls will be at least 450m from each other.

The courses as designed are

• Short – controls 2 3 5 with an effective length of 4.2km
• Medium – controls 2 3 4 5 with an effective length of 4.9km
• Long – controls 1 2 3 4 5 with a effective length of 6.3km

REGISTRATION IS CLOSED
