Your friend is right on in his assessment of the knowledge and
education of today's amateur. <br>
I was fortunate enough to be raised on and educated in both analog
and digital RF techniques.<br>
I was there when the digital revolution, in both computing and
signal processing, happened but<br>
not everyone was that lucky. I'm putting off my purchase of a
100D until: 1) I can justify the cost<br>
or pick up a used one cheap, 2) Apache proves itself as a stable
company, and 3) I'm prepared <br>
to really dig in and understand and/or modify the DSP PC
software. I'm stuck in a very noisy area <br>
and want to implement an adaptive noise cancellation system using
the 2 RX on the 100D so that <br>
I may be active in the years to come with this waning sunspot
cycle. <br>

<div dir="ltr">I have a good friend (who will remain nameless
here) who sent me a rant after reading ongoing complaining about
the Apache radios. I thought his comments were excellent and I
am going to share them here with his personal information
expurgated. Take it for what you will. I am sure it will offend
some people. But, frankly, it needs to be said. So feel free to
flame ME because I thought it appropriate to post it.

<div style="font-family:arial,sans-serif;font-size:13px">There
is an interesting phenomenon going on and, if you think
back, we saw the same thing with Flex. A fair number of hams
ran out and bought 10s and 100s and 100Ds without reading
the specs, checking out the available software, and thinking
about what they planned to do with the radios once they got
them.</div>
<div style="font-family:arial,sans-serif;font-size:13px">Now
they have radios that don't do what they want or don't do it
as they want or they don't know <u>how</u> to make do what
they want and they are getting pissy and blaming either
Apache or the volunteer developers or both.</div>
<div style="font-family:arial,sans-serif;font-size:13px">This
isn't about what the radios will or won't do, should or
shouldn't do except to the extent that a prudent person
explores those questions before laying down the long green.</div>
<div style="font-family:arial,sans-serif;font-size:13px">Rednecks
have a saying about black bass: "If it makes noise and
flashes, they gotta have it." Sic semper hamicus. They want
bragging rights about having the latest and greatest (Hey,
lots cheaper than a 9000) but they know little or nothing
about SDR, even in concept, let alone down in the
mathematical weeds. Worse yet, some think they do. </div>
<div style="font-family:arial,sans-serif;font-size:13px">Now
they are stuck and need someone to blame. The fact that they
made ignorant, thoughtless purchase decisions seemingly
never enters their heads. I find myself wanting to scream:</div>
<div style="font-family:arial,sans-serif;font-size:13px">THIS
ISN'T AN EFFING TOASTER!!!</div>
<div style="font-family:arial,sans-serif;font-size:13px"> </div>
<div style="font-family:arial,sans-serif;font-size:13px">This
underscores an argument that I have made before. The FCC
exams are obsolete. The OPs who lament that newbies don't
know anything about radio have had the tables turned. Now it
evolves that they may be able to tell you all about grounded
grid triodes but they don't know jack shit about decimation
or the difference between DDS and DDC. Rather than asking
the examinee to calculate parallel inductance in a circuit
(that nowadays is packaged in a chip, anyway), they need to
begin asking if people understand, in at least a general
way, what an FFT is and why one would use it.</div>
