WC8VOA Repeater News
The production model DR-1x with software revsion 1.00Z was installed on Feb. 8, 2015
The Fusion repeater is operating in automatic mode. It will transmit digital when it receives digital, and analog FM when it receives FM.
To avoid the digital "noise" when in FM mode, turn the tone/squelch of your unit on with a PL of 123.0. This tone is transmitted on FM mode only, so your receiver will not open the squelch when a digital transmission is in progress.
In this configuration, check the signal strength indicator before transmitting to insure that a digital QSO is not in progress.
Prices for Fusion transceivers is decreasing, and more operators are using the repeater.
Please do not key the repeater when a digital QSO is in progress.
In March 2014, the WCARA was offered the opportunity to participate in Yaesu's beta test of their DR-1 combination digital/analog repeater. This was something that we just could not pass up, and the repeater was installed shortly afterward.
The repeater is capable of both 2m and 440 mhz operation, although not simultaneously or as a crossband. It has been installed to operate on the WC8VOA repeater 145.390(-) frequency, with no tone required. It presently operates at 50w output, and is capable of both digital and analog FM operation. The digital mode utilizes C4FM protocol, which is an open source protocol.
Along with the repeater, the club received a dual band mobile FTR-400 digital/analog transceiver, and a dual band FT1DR handheld. These units are capable of both digital and analog transmissions, and include a GPS and ARPRS operation.
The repeater has several combinations of operating modes. Initially, it was installed to transmit analog FM, regardless of whether it received a digital or analog incoming signal.It is now in full automatic mode, which means that it will transmit digital when receiving digital, and analog FM when it receives analog FM.
In this mode, a transceiver set to receive analog FM will hear "noise" when the repeater is transmitting digital. To provide a method for FM users to exclude this noise, the repeater sends a 123.0 tone when transmitting FM. The user can set the tone squelch on their unit to this frequency, and their receiver will only respond to the FM transmission. A digital user will not hear the FM transmission.
The digital capabilities of this repeater are quite extensive. Aside from voice communiction, it can simultaneously transmit digital data files and/or pictures. Call groups can be established, along with unique digital identifiers.
The repeater is open, no tone required. Everyone is welcome to experiment with the repeater's capabilities. To find out all of the operationl capabilities, go to Yaesu's website and download the operating manuals.
