<p class=MsoPlainText>Hi Bruce/Roland,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>The PennyWhistle has arrived and is built and complete. It
is a very nice easy to build kit. I really like the quality of the parts as
well as the design. I do have a low pass filter which is good for 50 watts.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Another question, looking back at Roland's statement "<span
style='background:yellow;mso-highlight:yellow'>TX-RX commutation of the antenna</span>".
Can I safely infer that I shouldn't be receiving any signal back through the PennyWhistle?
Everything is working with the exception of the SoftRock received signal when
going through the PennyWhistle. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I'm thinking if I dig through the documentation on HPSDR
I'll find the receive and transmit antenna are two different antenna or something
like the use of a duplexer is needed.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks,<o:p></o:p></p>

<p class=MsoPlainText>> Hi Dave,<o:p></o:p></p>
<p class=MsoPlainText>> You can use Pennywhistle with any QRP rig, but you
need to send it a PTT<o:p></o:p></p>
<p class=MsoPlainText>> signal. I am using one with my SDR-Cube project, and
<span style='background:yellow;mso-highlight:yellow'>I needed also to put<o:p></o:p></span></p>
<p class=MsoPlainText><span style='background:yellow;mso-highlight:yellow'>>
relays for the TX-RX commutation of the antenna</span>.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Dave,<o:p></o:p></p>
<p class=MsoPlainText>Also remember you will need to add your own low-pass
filter(s) to the output<o:p></o:p></p>
<p class=MsoPlainText>of Pennywhistle, to insure sufficient harmonic
suppression on the band(s)<o:p></o:p></p>
<p class=MsoPlainText>you intend to operate.<o:p></o:p></p>
