Hi Herb (KV4FZ), You said "but the 50 turns is going to be a chore"
The only problem I find with winding a core with many turns is keeping track of the number of turns. What I do to solve the counting problem is that I take a zoomed in picture showing all the windings (using my smart phone camera, or one of my dedicated digital cameras), and this allows me to easily count how many turns are really on the core (versus what I thought I counted as I wound the core). Take the picture so the core fills up almost the entire camera screen, then when you view the picture you can zoom in even more (as needed) as you move around the core counting turns. I then add or remove turns as necessary for the desired number of turns. 50 turns are easy to count using this method. I just counted 103 turns on a T68-6 core using this method (wire size 30 awg = 0.010" diameter), and it took less than 2 minutes to count. I now often watch TV while winding cores since real time counting is no longer a critical task. 73, Don (wd8dsb) _________________ Topband Reflector Archives - http://www.contesting.com/_topband
