Your point is well made. A number of commercially available external

I have to agree with you...
Not having the auto tuner in the Recieve path would be a REAL good reason
not to buy FlexRadio's internal tuner!!
I've used an ICOM AH-4 for years with several radios including the SDR1K.
(Built my own AH-4 controller.)
Also our club uses an external auto
And certainly for me...
I think us successful SDR1K owners long ago lost any manual labor naivety

Instead we tend enjoy it...

V1.10.4 is absolutely terrific in semi QSK mode!
Although I'd like to see another dozen or so ops weigh in on their

Hi Jerry,
I think QSK results are highly "processor," Windows version and
associated executing apps dependent.
With flexRadio we all have to be careful about the performance of our
computer when making high end performance statements. Performance
statements are meaningless with out a the defi

With at least a 3.0 Ghz machine, I'd say careful testing will show the 5K

Hi Tim,
As I work through the procedures for SDR1K calibration, I assume all

My SDR1K is sitting on 7.010. Nothing but noise. Keeping AGC-T

put the Preamp on Low the noise level jumps to -94dBm and when I put the

Hi all,
With interesting results, I spent some time this morning testing SVN 1917
machine utilization. My bit of testing lead me to believe that:
1. In transmit mode, performance is unchanged from ver 1.10.3
2. With high performance dual processors performance will be rock solid
for all modes.
