[Discuss-gnuradio] USRP / LFTX PTT

[Faschingbauer, Alexander]

Hello,

i want to connect a RF power amplifier (PA) to the USRP / LFTX board.
It is recommended to control the PA with an external signal to switch it from 
standby mode into transmit mode.

The amplifier has an input for PTT- control so i need a logic signal from the 
USRP / LFTX board which indicates transmitting.
(Fitting two signal levels together would not be a problem.)

Is there any output signal on the USRP / LFTX board which i can use for my 
application?


Thanks a lot!

Alex
