The idea is that while transmitting at high power (say 50W or 100W), the voltage that the radio sees can easily drop below 11.7V because of the voltage drop. This is totally fine for the battery, but many radios need at least 11.7V to function properly. | The idea is that while transmitting at high power (say 50W or 100W), the voltage that the radio sees can easily drop below 11.7V because of the voltage drop.

- | * When connecting the Booster for the first time (with no load on it), I noticed that the voltage of the battery side distribution block dropped very quickly for a very brief moment, which was enough to reboot the Packet and Echolink computers as well as the modem. I'm not sure why that happens but I tried it a few times and it happened every time. As such, I would suggest having everything turned off before connecting it. Once connected, there was no other issues. | + | * When connecting the Booster for the first time (with no load on it), I noticed that the voltage of the battery side distribution block dropped very quickly for a very brief moment, which was enough to reboot the Packet and Echolink computers as well as the modem. |
- | * I initially had the output voltage of the Booster set to 14V, and using the batteries, everything worked as expected. | + | |
- | * When transmitting an HF AM carrier at 100W and a short 440 FM carrier at 50W, the 13.3V output dropped to 13.2V while the input of 12.4 V dropped to 11.4V. | + | < |
