A few quick thoughts. No fault on your part meant to be implied ...?
1) cabled correctly? QMX to transceiver input port of amplifier? Amp connected to antenna?
2) Amp set to the band you wish to transmit on if it's not one that can automatically sense the incoming frequency? If it can't then you'll like get a High SWR or Power protect condition on the QMX when you key or press 'tune' from DiGi software applications.?
3) can the amp/tuner handle the power coming out of the QMX? Likely in the 4-5 watts range??
4) I believe the QMX needs to be shutdown and restarted if a Power or SWR fault is detected.
Hope this helps

Hello Ron
I am reiewing your post from december. I have new kit built High Band QMX which will connect to my antenna normally, but show high SWR/protection if I place tuner of amplifier in the line. Works fine otherwise. You appear to have had a similar ?issue. Did you find an explaination/solution, l can¡¯t find one on this thread.Thanks for your help.
