Frequently Asked Questions

AI
A regulated power supply maintains a constant output voltage regardless of changes in load or input voltage, which is critical for protecting sensitive radio electronics from over-voltage.
Check your radio's manual for the maximum current draw during transmission. It is generally advisable to choose a power supply with a capacity slightly higher than your radio's peak requirement to avoid overheating.
Electrical noise from a switching power supply can bleed into your audio or create interference on your frequency. Noise offset or filtering helps ensure a clean signal and clear reception.
