Mic mod | uSDX+ | 8 Band SDR | SSB/CW QRP HAM Transceiver | Issue with Iambic paddle + MIC resolved

Problem description: 1) CW iambic mode works well when the Speaker-Mic plug remains disconnected. 2) To switch over to SSB, the mode has to be first changed to LSB/USB, before plugging-in the Speaker-Mic. 3) If the Speaker-Mic plug is plugged-in with iambic mode selected, the rig goes into continuous DIT transmission, and then hangs with TX keyed continuously. Solution: This video describes the mod/work-around - to enable trouble-free switching between CW iambic and SSB modes without the need to pull-out or plug-in any connector. Its's a two-step mod. The first mod is on the main uSDX board, and the second mod is on the supplied speaker-mic (that has an LED to indicate TX). If you are supplied with a different speaker/mic, then the second mod may not be necessary. #arduino #wb2cba #software defined radio #DL2MAN uSDR uSDX Plus V2 Review 10/15/17/20/30/40/60/80m 8 Band SDR All Mode HF SSB QRP Transceiver 4000mAh Battery
