I enjoyed conversations with Mark about theory topics like the merits of trying to increase NXDN capacity by splitting the data stream, or overcoming the effects of modulation interference when using adjacent 6.25kHz frequencies. His extremely in-depth knowledge on these and many other product technologies made him an invaluable resource for me as a field integrator and in serving existing customers. I always found Mark to be dedicated and responsive, and would he happy to work alongside him in the future.
