Repeaters

The Stutsmanville Repeater Complex, located North of Harbor Springs Michigan, is the home of four Ham Radio repeaters serving Northern Lower and Eastern Upper Michigan.

The view at the right is the main repeater room built by the Straits Area Amateur Radio Club and home to the W8GQN SAARC club repeater and the N8DNX UHF repeater and the W8CCE UHF D-Star repeater and gateway. The WB8DEL 220 repeater is located in the main transmitter room right next door. The W8GQN, N8DNX repeaters run on a common controller and share a 1.6 to 450 MHz remote base, weather radio, and IRLP node 4450. The W8CCE D-Star repeater is functionally separate but shares antennas with the N8NDX analog UHF repeater.

N8DNX Repeater – CCECPSCO RACES

The N8DNX UHF repeater is owned and operated by N8DNX and provides wide-area coverage. Using separate receive and transmitt antennas and a receive preamp up at the receive antenna, this system provides HT coverage upwards of 50 miles and mobile coverage for nearly 100 miles.

PL Tone Transmit 107.2, Receive 107.2 when necessary
Final Power 250 Watts
Repeater Vertex VXR-5000
Power Amplifier TPL
Receive Preamp Angle Linear High-Level Redundant Pair Preamp
Duplexer (none)
Transmit Line Shared with W8GQN repeater
Receive Line 550′ LMR-400
Transmit Antenna Sinclair 8 Bay Dipole array at 407′, HAAT 785′
Receive Antenna Sinclair 8 Bay Dipole array at 477′, HAAT 856′
Power to Antenna 55.9 Watts
ERP 444.2 Watts

W8CCE-B D-Star Repeater – CCECPSCO RACES

The W8CCE-B D-Star Repeater has now replaced the KO8P analog repeater. It uses the same transmission lines and antennas as its predecessor and therefore has similar coverage.

We are currently looking for a power amplifier for this repeater. Once that is in, we should have a good working model for a very high-profile D-Star system.

More information on this repeater is available at the following URL.

http://www.w8cce.org/dstar/index.html

Frequency 443.375 MHz +5 MHz offset
Final Power 20 Watts
Repeater Icom Dstar controller and VHF module
Power to Antenna 7.5 Watts
ERP 59.5 Watts

Controller

This controller is used by the W8GQN and N8DNX repeaters. Having these two systems tied together this way permits the use of most of the controller features and accessories from either one of them and linking between these systems as desired.

Controller Link Communications RLC-3
Port 1 N8DNX Repeater
Port 2 W8GQN Repeater
Port 3 HF Remote Base Radio
Port 4 VHF/UHF Remote Base Radio
Port 5 (unused)
Port 6 Weather Alert Radio
Port 7 IRLP Node Computer
Port 8 (unused)

Remote Base

This remote base system covers the 1.6 through 440 MHz Ham bands, all modes, as well as general coverage HF receive. Having this remote base attached directly to the same controller permits full HF, VHF, and UHF remote operations (where permitted) from all three repeaters. In addition, this configuration permits direct linking, as desired, to most other repeaters within aproximately a 100 mile radius.

HF Radio Kenwood TS-450S, 160-10 Meter Transceiver
VHF/UHF Radio Yaesu FT-736R, all bands from 50 Mhz to 450 MHz
HF Antenna Hy-Gain 18HT
6 Meter Antenna Single folded dipole at 50′
VHF/UHF Antenna Diamond X3200A

IRLP Node 4450

The IRLP node permits linking, via the Internet, to more than 1,000 other repeater and simplex radio systems around the world. More information about IRLP is available at http://www.irlp.net.

WB8DEL Repeater

The WB8DEL 224.560 repeater is also located at this site, but is very much separate from the other three repeaters. Del, who owns and operates this machine, maintains the broadcast systems here and at other sites. He also has an envious location for his repeater antenna right at the top of the tower, above the FM broadcast array. Needless to say, it covers the area very well — often outperforming the other repeaters at this site. He’s also taken his broadcast background to heart producing interesting ID announcements for this repeater Certainly a system to check out if you’re in the area with 220 equipment.
