That's because you are OLD and set in your ways.  Just admit it.  Smiley

Here is the list of my radios that I use for SWL in the order that I use them:

1. QS1R www.srl-llc.com
2. Perseus http://microtelecom.it/perseus/
3. Watkins Johnson WJ-8711 http://www.universal-radio.com/catalog/commrxvr/1500.html
4. National NC300 http://www.universal-radio.com/catalog/commrxvr/nc300.html
5. Collins 75A-4 http://www.wa3key.com/75a4.html
6. Hammarlund HQ-120 http://www.radiomuseum.org/r/hammarl_mf_crystal_hq_120_x.html
7. Hallicrafters SX-100 http://www.universal-radio.com/catalog/commrxvr/sx100.html

Honestly, I turn on the WJ, 75A-4, NC300, HQ-120, or SX-100 maybe once a year now.  It is painful to go back to using a radio with knobs after becoming used to the SDR software for the QS1R and Perseus.  The outstanding audio from the QS1R is why I use it the most.  I am an OLD misanthropic curmudgeon but I successfully have made the transition to SDR for SWL.  You can too if you keep an open mind.

Old yes, set in my ways not necessarily.
I like the full panorama display of SDR radios
and the receive performance on some is extraordinary.
But.....I'll buy an SDR radio when they put a few knobs on it!  Grin
And have the computer and display built in.
Not that much to ask for, is it?

The display could lay flat on top when not
in use, then fold up and slide forward for operating.
You could have the option of plugging in
a keyboard and mouse and operating "computer style"
....or using the knobs below the display,
or a combination of both.
Best of both worlds.  Grin

You could still use the mouse to click on Panorana display
to tune in a signal. VERY handy especially in contest.
Yet have the AF Gain, Mic Gain, and other
often used controls on knobs instead of
searching for one of those slider controls
all bunched together on the screen.

Just some ideas.......

I'd say by your response that you are more set in you ways than you realize.   Smiley If they integrate the computer and display into the radio then you are stuck with whatever the manufacturer used at the time.  With an external PC and monitor, you can upgrade the processing power as well as the screen size (or multiple screens) when you want and you are not tied to the decisions that the manufacturer made for you.  Most guys only want knobs because they have not spent any serious time with the SDR software.  Once you get used to it, a knob is the LAST thing that you want.  Knobs are seriously overrated (and limiting).

To KE5JPP - Jean, I'm considering the purchase of the QS1R DSP receiver. Could you give me your expert opinion on such thinks as performance, ease of install (software), computer horsepower required, flexability, ect.  Also have you compared the QS1R to other DSP radios(besides the Perseus) like the Win-radio Excalibur /Pro ? 

Thanks

Hi Bob, I also have a Perseus and I have used a friend of mine's Winradio Excalibur.  I dislike the Winradio software and Winradio is not quick to fix problems if at all.  The list I posted earlier in this topic shows my order of preference of the receivers.  There is some interesting stuff posted to the QS1R Wiki that compares different receivers that you might want to check out too to make a decision.

 Hi all. Any SWL who uses a computer to "listen" for him,





















 

 Hi all. Any SWL who uses a computer to "listen" {often when he is fast asleep},should be ashamed to call himself a radio amateur. Perseus is killing the hobby. Broadcast band "listeners" are now using that receiver to record,then they listen to its recordings,often days,weeks,or even months later,and have the nerve to report these as to magazines. Real DXing,can only be done in real time.That is skill,not listening to computer recordings. Roll Eyes

Hi Ken,
I am with you. I have owned 2 SDR-IQ's and find them interesting pieces of test gear, but I don't care for a receiver that has to have a separate computer to run it and no knobs.

That's where the Elecraft K3 comes in. It has superb sync detection and the P3 display is as good as the SDR displays- and no computer required. Now that the VGA card is out, I can see the display from across my lab.

I use a Microtelecom Perseus and WinRadio G33DDC Excalibur Pro.  However, if the station is in the clear, very weak and I want to actually recover enough audio to ID it, my EAC R390A and Sherwood SE3 combo win hands down, every time.

Young Padawans should value wisdom over marketing hype before making light of those who's life experience has brought the wisdom them to hold their tongue in public forum so as not to appear foolish.....
