SoftRock SDR receiver with Kenwood TS-850s

Here is a report from Jack about use of a SoftRock SDR receiver kit working in tandem with his Kenwood TS-850s. Click on the thumbnail below for a larger view. Also included below are two Youtube video links. Thanks, Jack!

 

Good evening,

The CAT interface cable for my TS-850s came in today.  I also have finished a monoband SoftRock SDR for the Kenwood 8.830 MHz IF.  I used the PowerSDR/IQ software from here:

The software now works directly with some Kenwood radios and with the K3.  It can also link up with Ham Radio Deluxe (HRD).  Here are a couple of vides:

The software is superb.  By interfacing the $20 SoftRock to the TS-850s, I get the following:

• A pandapter
• The SDR receiver with an additional sub-receiver.  This includes DSP filters and noise reduction.
• The SDR is muted automatically when transmitting through the Kenwood.
• Software control of the combo as well as control via the radio knobs.
• Interconnection with HRD

This is an impressive and inexpensive combo.

Dual SDR Receivers

This is an earlier report from Jack about his success running dual SDR receivers controlled by a single PC. Click on the thumbnail for a larger view.

Good evening,
Last night I began running two SDRs: a general coverage unit connected to the Beverage antennas, and an IF unit connected to the TS-850S.  Each goes to a separate outboard sound card, but to the same PC.

The wrinkle was how to manage the audio going from the sound cards to the amplified sound system.  I decided to take a hint from W4BXI's approach to audio, and I hooked up a six channel Behringer mixer.  It works great!  It also looks like the PC will handle both SDRs okay.

Now if I can just get two monitors working like W4UOA...

Regards,
Jack
