A low cost, high current power supply for Amateur Radio utilising a Server PSU.

Design Interface (There are some that already exist, however most of this use ATX 6pin connectors or other less useful connectors - if you can actually find the designs)
Look into reducing EMI

Identify maximum voltage obtainable from supply.
- OVP cuts in at about 13.9v, however OVP protection will trip if a 1A load is suddenly attached by 13.75v.
Modify PSU to boost voltage 12v->13.8v (or as close as possible)
- This is possible using a resistor between the 12v sense-return pin and ground. 260Ohm resistor suggested.

Original PSU was going to be a Dell POWEREDGE 2950 Redundant Power Supply however upon testing this supply, voltage would not rise above 12.2v and would drop to unusable voltages under load.
