West Mountain Radio has collaborated with N8XJK to bring back the popular TG Electronics Booster! This unit will help you get the most life out of your battery.
This model is an improvement on a design that has been widely used in Amateur radio for more than 15 years.
The N8XJK Super Booster was specially designed for use with a radio.
When the voltage from a battery drops, the Super Booster brings it up to a level that allows for optimal transmit. The output level can be set by a trimmer pot to any value up to 15V. The advantage of using the Super Booster is that a Lead Acid battery is rated in Amp-Hours for use down to 10.5V. However, radios require at least 11.7V to transmit. That results in over one-third of amp-hours in the battery cannot be used for transmit without a booster.
For example, when doing 100W SSB with a 74AH battery (car size) allows for 10 hours continuous transmit. When using the Super Booster, the result is at least 15 hours of continuous transmit. Even at the last amp-hour of the battery's life, there is 10.5V and at least 11.7V to the radio. Transmitters tend to be more efficient at higher voltages, therefore there is additional savings by using, for example, 14.5V.
The Booster Remote control/monitor unit is a compact remote head that monitors input/output voltage, as well as error conditions like over-voltage and over heating.
Super Booster readily accommodates the remote control or to connect units in parallel to achieve 80A or 120A.
