[Premium-Rx] Hello and what is the best receiver?

[Carcia, Francis A HS]

hi 
I think the SDR1000 software effort is very cool. These guys did a fine job
and I commend them.
But, I find it hard to believe their hardware performance claims. Ever since
the first QEX article I've had a number of emails with Youngblood. Again I
can't say enough praise for their software effort. Look at any modern mil
receiver like say the 95S1 or Cubic 3250 all have 1 stage of conversion with
a roofing filter then do base band conversion. Also I think a better
preselector is required for real performance say like the Cubic 3150
optional preselector. Then I'm talking real strapping performance.  fc

I'd have to second that motion, although I don't own the SDR-1000.  Have a
look at "gnu radio" on the web.  Great opensource mix of folks doing some
very nice coding for software radio.  Check our
http://www.gnu.org/software/gnuradio/
<http://www.gnu.org/software/gnuradio/>   It's not just Linux either,
although many if not most of the developers prefer that platform.  Why
re-invent the wheel?

Hi Adam,
 
Thanks for your friendly introduction to the group! It sounds like you have
a broad and interesting background in radio electronics and computers.
 
In my opinion, the Flex-Radio SDR-1000 sounds very close to the receiver
development effort you propose. After watching its progress for more than
two years, I made the plunge a couple of months ago and bought a
receive-only version. My intent is to see if the SDR-1000's excellent
close-in dynamic range/RF performance will translate into better tropical
bands reception and foreign  medium wave DXing for me. I have a blog about
the SDR-1000 you might like to read: www.sdr-1000.blogspot.com
<http://www.sdr-1000.blogspot.com> .  It is written strictly from this point
of view, as my radio interests are below 5 MHz, particularly Pacific and
Asian stations on medium wave and 90 meter band Indonesian / PNG local
broadcasters.
 
Anyway, I just wanted to make a mention of the SDR-1000, as it's possible
you may not want to "reinvent the wheel," but jump on board the SDR-1000's
open source development. Many enthusiasts are contributing to this unique
radio...I look forward to each new beta release of the software! There are
some neat features and improvements on the way for the next six-month plan,
such as expanding the 20 kHz panadapter display to 96 kHz width.

Hello Group,

First I would like to introduce myself, I am Adam Harriman. I am an amateur
extra - N4ZSM and I have been licensed since I was 14.  I feel lucky to have
a wife who also has a license KG4UGB.  We are located near Melbourne FL,
where the storms hit.  We used our VHF radios during the storm and were
grateful for being amateurs.

I am now working with someone who would like for me to develop a premium HF
receiver. This receiver will have special features which are not available
in current receivers but are not very interesting to this group. This forced
us into a custom design.  I am currently working on the feasibility stage.
There is no guarantee this effort will continue.  Since this is a premium
receiver group I think my questions are on topic, if I violate the rules
apologize. 

Since I am new to the list and I just may develop a next generation premium
receiver, I thought it would be wise to take a look at the list of the best
all time HF receivers and perhaps obtain some advise from the smartest most
knowledgeable folks on the subject. 

Mostly I wish to look at the design requirements and perhaps take a peek at
the implementation where possible.  Does this group have a list of the best
receivers? Feel free to send me your comments on the receivers you own.  I
desire to know which receiver is the hands down best.  If there is more than
one, I would like to know the list.  I want to take the list and review the
specifications for each unit and perhaps to some extent the implementation.
The goal is to make the next generation and make it affordable. During my
review I may compile a list of the specifications and provide some analysis.
