[Dstar] IC-91AD not transmitting while on the charger???!!!

[vk2vvv]

One further thing I stumbled across Susan, is this quote from the operators 
manual:-

Quote


". Up to 5 W (approx.) of maximum output power is provided
with the external DC power operation, however, when the

supplied voltage exceeds 14 V, the built-in protection circuit

activates to reduce the transmit output power to 0.5 W (approx.)."



It would pay to see what the voltage across the charging terminals is during 
charging.

Cheers again
