The Kenwood TS-590SG... a great value in an HF transceiver!  Perhaps you're thinking you might opt for a 590SG yourself.  

Incremental changes help performance and function to evolve.

■ An even higher performance receiver with superior adjacent dynamic range.
■ Advanced AGC control through digital signal processing from the IF stage.
■ Highly reliable TX outputs high-quality TX signal.
■ New morse code decoder. Scroll display on the 13-segment display unit.
Characters are shown in a dedicated window on ARCP-590G.
■ MULTI/CH knob (with push-switch) and RIT/XIT/CL key also configurable in
addition to existing PF A and PF B programmable functions.
■ New Split function (TS-990S-style) enabling quick configuration added in addition to the existing Split setting.
■ Transceiver equalizer configurable by mode.
■ FIL A/B configurable independently with VFO A/B (convenient during Split operation).
■ Front or rear PTT selectable for Data PTT.
■ Switching from HI CUT/LO CUT to WIDTH/SHIFT possible for reception bandwidth changing in SSB mode.
■ DRV connector switchable to antenna output function.  For hams wanting to integrate a pan adapter with their 590SG, this new cabability is perhaps the single most significant advancement over the original 590S.  More about this at https://www.sdrplay.com/. and https://www.youtube.com/watch?v=jX91TtOOGqQ .  The RSP1A is Sdrplay's newest improved entry-level SDR receiver.
■ Large display with superior visibility.  LED backlight color tone configurable in 10 steps from amber to green.
■ Speech processor independently configurable for microphone transmission and voice message transmission.
■ 20-step expansion of settings ranges including TX monitor and CW sidetone, etc.

Important note... New 590SG owners are urged to first study the operator's manual.  Also, you may want to become a member of the 590's user group at https://groups.yahoo.com/neo/groups/KenwoodTS-590/info as well as a frequent visitor to the 590 family resources website at http://www.g3nrw.net/TS-590/ .  

Here is KC5YR's suggested TS-590SG menu configuration if handling virtual tx audio via  the USB cable:  Other default settings as per pages 15 – 19 of the instruction manual except as noted below:

 

Menu number Description Default Current
27 Auto mode Off On
31/33 TX filter ssb/am low cut 300 100
32/34 TX filter ssb/am high cut 2700 2900
35 Speach processor effect (see note below) hard soft
36 TX equalizer (see note below) off Off
59 HF linear amp control relay (if applicable) off 3
67 & 68 Com speed 9600 115200
 69 Audio input line for data ACC2 USB
70 Audio source of send/ptt front rear
71 USB input audio level 4 3
 76 Data VOX off on
77 VOX delay 50 15

 

MIC -  Level 12 when routing outboard hardware processed analog audio to the 590SG.   This control is not applicable when handling virtual audio via the USB connection. 

Menus 36 and 37 are not applicable when using outboard processed transmit audio techniques to the rig as compression and EQing are integral to most outboard processing schemes.  

Hams who prefer using the 590SG's built-in TX EQ should install Kenwood's control software as discussed at http://www.kenwood.com/i/products/info/amateur/ts_590g/arcp590g_e.html which facilitates setting up this functionality.  

Use a type AB USB cable for hookup to the 590SG.   Windows should automatically install the necessary silicon labs driver.   Check Windows Device Manager to determine which port is designated for the UART and make certain that the 590 and ARCP-590 software is set up to reflect the correct port, baud rate (preferably 115200). 

It should be noted that this page is purposely aimed at ham's desiring to utilize their 590 for virtual audio handling as described elsewhere on this website by clicking Digital audio for the Kenwood 590SG .
