SignalSlinger is a 5-Watt Radio Orienteering transmitter for the 80m band.approprate for Classic, Sprint and FoxOring. It can be set out days in advance and transmit on a multi day schedule.

Detailed user and assembly instructions are in the SignalSlinger User Manual.

This kit includes all the parts listed in the Assembly Manual section of the User Manual, including the internal battery. The only additional things you will need to start using your SignalSlinger are:

• External 12v battery, one for each 'Slinger. For SignalSlinger to transmit, it must be connected to an external power source. A 12V LiIon battery pack is ideal. (Not included.)
• Antenna: It just so happens that we have a tuneable antenna for 'Slinger, the SignalStreamer 80m transmit antenna kit. (Not included.)
• Configuration cable: one is sufficient for configuring all your 'Slingers (Not included, but available in our store) It is important that you order our USB Configuration Cable because you can not configure your 'Slingers without one. You only need one to configure all your 'Slingers using either our free SerialSlinger program or a terminal program.

The internal battery keeps SignalSlinger's clock running for days without an external power source, so it can start transmitting at the preset time. An attached external battery, or configuration cable, will automatically charge the internal battery. Without the internal battery, a momentary disconnect from the external battery would lose the current time, preventing the transmitter from turning on at the preset time.

The SignalStreamer antenna kit (not included NOT YET availavle in our store) is 'Slinger's perfect match (no pun). You tune the signal by turning a variable inductor, until a set of LEDs reach maximum brightness. All the details are in the SignalStreamer User Manual.

To program 'Slinger, you connect the configuration cable (not included, but available in our store) between it and the USB port of a computer or smartphone. You only need one configuration cable to program all of your SignalSlingers. SerialSliger (Open Soruce) is the app that programs SignalSlinger it will download and install the latest updates, and will clone the appropriate settings into a set of SignalSlingers.

A null modem cable (not included) can be used to transfer event details from one 'Slinger to another without a computer or smart phone.
