Pete,
<DIV> </DIV>
<DIV>My amp got pretty hot during this process - I am wondering now if anything
is damaged. </DIV>
<DIV> </DIV>
<DIV>This obviously needs to be fixed - in the documentation. Maybe we
need to have an errata section where we accumulate these sort of items so no one
else has to experience it. Got out my infrared gun and was measuring temps
in the 120 degrees Fahrenheit range while the amp was just sitting there - so I
knew something was wrong. </DIV>
<DIV> </DIV>
<DIV>73's,</DIV>

Below is my e-mail from 11/21/2009. I was under the impression that the
documentation had been changed to correct the inconsistency back then but
apparently not.<BR><BR>Pete, N3EVL<BR><BR>"...***** High Performance Software

of the Pennywhistle Assembly and Operating Instructions document shows the
3-pin header numbers with 1 labeled as Bias Control and 2 labeled as ground.
<BR>This appears to be at odds with the schematic which shows 1 ground and 2
Bias Control. <BR><BR>Since tests with my ohm meter agree with the schematic,

<DIV>I did a search of e-mail that I have - not exhaustive by any means -
but has anyone noticed that the Bias Control and Ground Pin numbers are
reversed in the below diagram? (please see PennyWhistle connection
diagram in the pdf on the web-site)</DIV>
