Re: Operation under emergency conditions

Hi LU7DID,

If you really need to work at 5V, it is recommended to replace 78L05 by a LDO type 5V regulator.

For the TX amplifier, the output can be as low as 100-200mW if you power with 5V. You can test it.

Thanks,
Adam

Adam,
 
In a bare bones emergency situation to which extend the D4D works with a high capacity 5V pack as it's sole power supply? (assume connectors worked out properly).
 
¿Does the D4D work with less performance/power? ¿Works very degraded? ¿Doesn't work at all?
 
Thanks for your answer.
