I have been using low-band QMX with 50W amp for several months with 018 software. Today I uploaded the .027 firmware and that process went as normal, but afterward the QMX does not transmit. Tests look all OK (bias, SMPS voltages,supply 8.9V, Tx voltage 7.5) but on transmit 'T' the power is 0 or flickering 0.1W, but a valid 1.1 SWR (dummy load). The power meter on the dummy load does indicate a small output, about 100 mW.

I tried reloading the .018 firmware, but still no TX.? I tried a factory reset from the menu. Then I used the jumper to force bootloader reloaded .027 firmware, went through replacing settings and condition is still only tune level output.

I also have a high band QMX and I uploaded the .027 firmware to it a few days ago with no problems and have been using it successfully on 10 and 15 which has be quite open lately. This success led me to put the .027 firmware into the low-band rig.
