STOP IT! DigiKeyer is a digital (RTTY) interface - NONE of the microHAM CW interfaces failed. All three of the microKEYER II units from TX5C are still working in the shacks of the team members who took them home. Yes, one DigiKeyer failed and the team has neither told us how or why nor returned the unit for evaluation. However, there were a lot of other, more serious, problems with that operation. By the way, VP6DX had a dozen microKEYER II interfaces - every one worked flawlessly. Several other major DXpeditions, including 3Y0X, have used microHAM interfaces exclusively without incident in very difficult environments. The one DigiKeyer failure at TX5C is the ONLY failure at any of the major DXpeditions that have used microHAM interfaces. 73, ...
