Info pawer 5 v qlg1 external

GIUSEPPE #74681 Hello everyone, I have a problem with the PTT output of the qcx mini for 20 meters, it does not give me the 5 volts to power the qlg1.? I would like to know if it is possible to use a 5v power supplied by an external power supply to make the wspr beacon work.? thank you and have a nice day. 73 IU8EUN Giuseppe

I have 2 QLG-1's and a QLG-2 and use external power (not supplied by my QRP Labs equipment) on them all. For the QLG-1 units I use a 7805 voltage regulator IC to step down externally supplied 12 volts to 5V.? --Al WD4AH
