These are screening estimates from public FCC and Census data, not a filing-grade engineering study. Mark uses his existing tower with a mast to about 30 ft, and Aaron a radiation center of about 72 ft.

- Mark: 89.9 non-directional at 99 W, about 30 ft on the existing tower with a mast.
- Aaron: 89.3 non-directional at 95 W, about 72 ft on the existing tower. Aaron is also the control point.
- No showings needed. Neither site sits inside a second- or third-adjacent station's protected contour on these channels.
- Confirmed: off-air reception and no expected Twin Lakes tower problem, per Chris.
- Still needed: a localism bylaw amendment, site assurance letters and antenna quotes.

Site Checks
Mark on 89.9: Clear
- Closest stations at the planned 99 W: WMBI 6.6 km and WUWM 7.7 km. Every other station clears by more than 25 km.
- Channel 6: 99 W clears the Milwaukee low-power permit by about 0.37 km.
- IF: exempt under 100 W.
- FAA: no notice appears to be required. Confirm with the FAA notice tool.
- RF exposure: 15% of the public limit at ground level, worst case.
- WLCB: 6.27 km away, inside the 10-mile limit, with the required contour overlap.
- Off-air reception of WLCB is confirmed.
Aaron on 89.3: Clear
- WBSD clears by 0.37 km at 95 W. WTHX clears by 9.4 km and WOKL by 12.3 km.
- IF: exempt under 100 W.
- FAA: no notice appears to be required. Confirm with the FAA notice tool.
- RF exposure: 8% of the public limit at ground level, worst case.
- Off-air reception of WLCB is confirmed.
WLCB Move Zones
Screening areas within 11.2 km of the WLCB transmitter. No specific site is confirmed in either zone.

Control Point
- Aaron holds the Barix and EAS equipment, with audio arriving from the studio over the internet.
- Barix units send lossless audio over a wireless link to WLCB. Internet for WLCB can share that link.
- RDS stays at the WLCB transmitter.
- Both translators receive WLCB off the air, including the one at Aaron's.
- Path is 6.15 km with a ridge about 3.3 km out. 5 GHz is preferred; 900 MHz is the fallback if trees block it.
Open Items
- Send the bylaw amendment to the board by November 6 and adopt it by November 16.
- Fill in the board residence list for the localism exhibit.
- Antenna quotes, then antenna make and model for both applications.
- Written site assurance for both sites.
- Confirm the local public notice method.
- Wireless path check from tower height, including trees.
