The results with this third (and final---I promise!) test were most interesting (NOTE: for comparative purposes, I have square-bracketed---[ ]---the changes observed at the very same time intervals in the FIRST test, at the end of each observation line). Here goes: (1) 5455.0-KHz (cold start)---[0.0-Khz]; (2) 5455.0-KHz (unchanged)---[0.0-KHz]; (3) 5454.3-KHz (downward drift of 700-Hz from cold start)---[500-Hz]; (4) 5453.7 KHz (downward drift of 1.3-KHz from cold start)---[1.0-KHz]; (5) 5453.2-KHz (downward drift of 1.8-KHz from cold start)---[1.2-KHz], and, (6) 5453.2-KHz (unchanged)---[0.0-KHz0 The end result in terms of PTO drift with the fan off was 1.8-KHz, versus 1.2-KHz with the fan on. Interesting! That's a difference of 600-Hz, or HALF of the drift experienced with the fan running!
Thanks for doing this test! It is about what I get on the R4B as well. The fan test is interesting I have thought about putting a fan on but never have. If I do it would be nice to have a nice quiet fan. Is there an advantage to a DC fan? It seems a AC fan might be easier to wire up? _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
