Dear Jim, IO90BR

Attention, Warning
Biases are current limited however avoid to use biases with short circuited antennas.
The FDM-S3 has two antenna biases, one for the HF-2 input and one for the VHF input. The supplied voltage is 5V (max 150mA). They are activated and deactivated via the FDM-SW2 software. Two leds on the front panel allow to check the biases status. Antennas biases can be managed through the Tuning Step tab of the Setup window of the FDM-SW2 software.

Protect the VHF input with a suitable value and voltage capacitor so as not to inject DC current into your antenna if no preamplifier placed just under the antenna

Bernard
Thanks for the warning, Bernard.

I only use SDR Console and never have cause to use the bias-T, so my risks of an accident are minimal, thankfully.
