<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>***** High Performance Software Defined Radio Discussion List
*****<BR><BR>Hello folks,<BR><BR>I've been reading along the list for a while.
I stumbled upon hpsdr by chance when I wondered what TAPR was up to these
days. Doing google searches, youtube searches, I saw some of the different
things people do with software defined radio.<BR><BR>I have been seriously
considering putting something together and thought I would ask a few
questions. I would first like to ask if an OpenHPSDR rig would be suitable as
a primary radio?</FONT></DIV>

<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>The long answer is "YES"! I had the benefit of starting with HPSDR back
when just OZY and </FONT></DIV>

a PA module from</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>a discarded FT-747 (found in a trash can!). I integrated this with
the SDR-1000 to attain 100W</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>out and the low pass filters and tx/rx were included.</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>You can find deals on failed radios and rescue the PA and even if it is
smoked, repair is very</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>inexpensive. </FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>I have since progressed through the evolution of the HPSDR to the point
now that I still run</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>the same HF PA but with all the TAPR or NT supplied boards. I have a
separate system that I</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>use for a VHF/UHF IF system and .5 w is more than enough to drive
28 Mhz to 144/xxxx </FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>transverters. The only drawback to my main HF system is the fact
that the HF amp is only</FONT></DIV>
<DIV>good to 30 Mhz. My plan is to switch at the .5 w level to Pennywhistle
and drive a 3cx-800</DIV>
<DIV>amp on 6 meters.</DIV>

<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2><BR>Also, and I feel really silly for asking this. I noticed the
Mercury and Penelope boards each have their respective antenna connections.
Growing up in the age of fancy Japanese transceivers, I was wondering how
people hooked up to the same antenna?</FONT></DIV>

<DIV>Just consider them separate transmitter and receiver and add your own T/R
relay. Very simple</DIV>
<DIV>at low levels. NT Electronics sells a T/R switch with or without a 6
meter preamp. There are so</DIV>
<DIV>many options available it is hard to include them all.</DIV>

<DIV>****<BR><BR>I have many more questions, but wording them in a language
that a human can decipher tends to be a bit tricky. I started writing this
several hours ago, walked away, came back and hacked it to pieces.</DIV>

<DIV> </DIV>
<DIV>Please continue to ask questions about this exciting venture. It may
sound overwhelming at first,</DIV>
<DIV>but after a while it will start to make sense. I have worked with many
different configurations of</DIV>
<DIV>the HPSDR project and I do use it as my primary radio on HF & 432 Mhz
& 1296 Mhz EME.</DIV>
