[Elecraft] Advice needed: Remote Station Enhancement

[ab2tc]

Hi Don and all,

Hear,hear, Don. The receivers should have the pullup resistor to whatever
the appropriate voltage needed (within reason) *and* a steering diode in
series with the input. This will prevent another device with a higher
voltage from feeding current back into the device which could damage
semiconductors. Without the steering diode all receivers must use the same
pullup voltage. Of course a single receiver is not a problem either.
