Megler 147.180 Repeater Voting Receiver System

147.180   +600 kHz    82.5 Hz   Cape D Receiver
147.180   +600 kHz    82.5 Hz   Naselle Receiver
147.180   +600 kHz    82.5 Hz   Megler Repeater
147.180   +600 kHz    82.5 Hz   Warrenton Receiver
It is not uncommon in the Discovery Coast area for repeaters to have "dead" spots, pockets where a user has problems reaching the repeater receiver. In order to extend the coverage of the 147.180 Megler repeater, three remote receivers, in addition to the receiver at the repeater site, are employed. The user still receives the repeater directly, but their input signal may be picked up by a more favorably placed receiver. The receivers all listen on the Megler input frequency and 82.5 Hz PL tone. Receiver selection is accomplished with a Voting System that evaluates the signal quality of all the receivers. The best signal is routed to the transmitter.

The Cape "D" receiver overlooks Cape Disappointment State Park from 300 feet, providing hand held coverage in the park, as well as Ilwaco and Seaview.

The Warrenton receiver is located in downtown Warrenton, and fills Hightway 101 along the north shore of the River and the back side of Astoria.

The remote receiver at the 2000-foot Naselle site,  enhances coverage to the north on Hwy 101 and east on Hwy 30.


North Cove 145.310 Repeater

In addition, there is a second remote receiver at the Naselle site that works with the North Cove repeater. To use this receiver, transmit a 114.8 Hz PL tone (instead of the usual 118.8 Hz tone) while tued to the 145.310 North Cove repeater.
Why can I hear the repeater but I can't work it cleanly?

Many repeaters run higher power than a typical user, so the signal you hear is stronger than the signal you are generating. Add to this the fact that typically, a repeater receiver is hearing your transmission through a duplexer and filters that absorb some of your signal, and it's easy to see that your signal at the repeater is weaker than the signal you are hearing from the machine. This is particularly true if you are using a low power hand held.

Since most repeaters use CTCSS ("PL") tones, it is important that the tone arrive cleanly at the receiver. In areas of "multipath" the signal may become distorted, causing the PL tone to be mutilated enough that the decoder can't recognize it as a valid tone, and drops out.

The answer is multiple receivers, so you always have at least one that receives you loud and clear.
