December 30, 2017:  Mark:  Thanks for teaching me the fine art of troubleshooting!  Hope you and Paula had a wonderful Christmas and are looking forward to retirement in the new year!  Shane Toven, Laramie, Wyoming.

December 29, 2017:  Mark:  Just learned you have retired!!  Congratulations on an engineering life well lived.  I enjoyed your father’s book.  It was easy to see where you got your skills and sense of humor.  You truly rounded out the next generation from him.  It also seemed your father perhaps put some of his career ahead of family and that is where I so respect you and Paula for being a team but also having fun in life.  Best wishes to you and Paula and being released from the duty of having to fix things all the time.  Thank you for the advice and guidance through the years.  Dan Houg, Chief Engineer of KAXE/KBXE Radio Grand Rapids, Minnesota.

December 29, 2017:  Mark, Before we close our doors on the last business day of the year, I just wanted to take the time to wish you and Paula the best in your well earned retirement.  Even though we only had an opportunity to work together in person one time back in the 1980's on the Nautel and C-Quam installation at KFYR, Bismarck, I am still impressed by the level of professionalism you brought to the field of Broadcast Engineering.  I have not met another contract engineer in the past 30 years that could even come close.  Again, best of luck.  Jeff Bliss, KWGO in Minot, North Dakota.

December 27, 2017:  Hi, Mark..  Congratulations on your retirement.  Thanks for your Tech Tips.  Best regards, Jack Ondracek, RDI Radio in Bremerton, Washington.

December 20, 2017:  Hello Mark, just wanted you to know that I truly am pleased to have learned about your father's book and been able to read his story, an extraordinary one as you certainly recognize.  Marlin Taylor, Washington, D.C.
