<p>Looks nice. The coverage is 325 to 3800 MHz which is less than
some and more than others. It seems like all of these boards
require some sort of front end to turn them into a radio you
could use. This one is so high at it's bottom rx range that it
couldn't be used as a panadapter on an existing rig. <br>
</p>
<p>I guess I should figure out what all the letter combos mean fpga,
adc, fpgas and adcs</p>
<p>Actually I just rolled up a $100 bill and stuck it in my ear. It
seemed to improve my reception....<br>

Also a good "budget" board, with a lot of processing

<div class="gmail_default" style="font-family:tahoma,sans-serif">LimeSDR are
cheap sdr boards, but not very good. There is KiwiSDR
with fpga, adc and gps hardware, used by a network of
web receivers, but requires an sbc to be fully
functional. There are BladeRF boards, with powerful
fpgas and adcs. A bit pricey, but with a lot of sdr
power. There are also USRP boards - even more pricey,
but pretty much standard on the "budget" end of the
fpga+adc spectrum.</div>

<p class="MsoNormal">I came across an FPGA dev
system with transceiver modules by “Opal Kelly”.
It seems to be flexible for big designs and
somewhat cheaper I think than boards from
vendors such as HT Global. Is this something
advanced hams have used for SDR? The LimeSDR
tech support (0.00 so far) is turning me off
from thinking about investing in their product.
So was looking at alternatives for the future
that could grow. Just FYI. </p>
