<p>All:</p>
<p>I have been asking a bunch of questions lately, and wanted to
share what I've learned -- before I ask one more question!</p>
<p>1. I asked about low output from Penny. My Icom microphones
need 8V of bias; I've learned that the board provides 2.5 volts.
Now that I know this, I can easily provide. I have studied the
Penny schematic and verified that if the bias jumper is <i>removed</i>
then no damage will occur from externally applied bias.</p>
<p>2. I have been provided a great algorithm for adjusting power
amplifier gains, much easier than my 2 wattmeter plan: Run the
two-tone test into a dummy load, and adjust gain to achieve 50W
indicated on a wattmeter -- that's 100W PEP.</p>
<p>Thanks to <i>everyone </i>who has responded to my questions.</p>
<p>I have one more:</p>
<p>I'm running PowerSDRmRx on Windows7 Home Premium. When I
double-click the application, I get the winders security, "Do you
really want to allow the following program from an unknown
publisher to make changes to this computer?" If I select "yes",
it runs. How do I make this winders nonsense go away? I have
already done, <i>right-click ==> properties ==> Security ==>
allow system, administrators and my user account</i> full
access. Still, I get the nag! Any way to make it go away??</p>
<p>Thanks & 73,</p>
<p>Jim</p>
