Hi Ed,
Just remembered this post.
What other DDC/DUC radios have you compared against QSD/QSE?
I may be missing something here having compared Softrock/UHFSDR/SR63ng+Mobo etc. vs. HiQSDR,+Preselctor-PA/openHPSDR Hermes/HermesLite2.
DDC/DUC for me proved the winner instantly but after these many years I will put a SR63ng+Mobo-4.3.4 on the air in case I am proved wrong.

Hello Ravi,
Yes, the basic configuration as used in the Softrock, ie NOT DDC/ DUC, will put the IC7300 in its place where it belongs.
For interest, I regularly get reports from Scottie Globemaster SDR owners telling me about their experience.
Here is one example:
*"I have compared the GM with my IC-7300 . ( SSB and CW )*
**
*It is very significant different : The IC-7300 is like an noise-generator ...*
**
*Stations which can copied on the GM absolutly clear .... they are on the IC-7300 much , much more*
**
*in noise and weak . Ofcourse : Using the same antenna for compare ."*
He then goes on to say after comparing many other receivers :
*"The worst receiver by far ... with the worst signal-to-noise ratio is the IC-7300 !!!! "*
*
*
Not my words !
**

So forget about all these fantastic digital radios with their limited dynamic range,
stick with the 24 bit analog radios with solid Bandpass Filtering if you are interested in performance.
BTW, It is so refreshing to see Yeasu using an analog front end in their very latest SDR radio.
THERE MUST BE A REASON WHY.
LOL , as if they did not know !
Don't be caught up in the digital hipe !

Thanks Alan...
My RXTX 6.3 with Mobo 4.3 is successfully sorting to action...
What is more surprising is that the Softrick + Mobo combination is preforming better over 7300 under low signal conditions probably due to the BPF acting as preselector in RX mode aiding the reception &? that its what is missing in 7300...
Thanks again Alan...
