This is the third in a series of videos on diagnosing and debugging problems with the transmit chain on my homebrew sBitx transceiver. On this multi-band transceiver only one low pass filter should be in the circuit at a time. In the last video I demontrated with LEDs that more than one relay was being engergized. But sometimes the more you work on a rig, the more problems you cause or find. This video shows the next step in the debugging process and a couple of side trips along the way.
More details on the sBitx rig and this problem on my blog:
