I commented earlier and neglected to say review the receiver performance as listed on the Sherwood Engineering site under Receiver Test Data.  It is sorted and presented as Narrow Spaced performance.

Limited time Labor Day Special - Free Shipping for all domestic S-BOX and Y-BOX orders

Bob Wilson, N6TV
 

All S-BOX and Y-BOX orders received by midnight Pacific Time on Labor Day ( 2018-09-04 07:00 UTC) will qualify for free domestic shipping via USPS Priority Mail.  Limit:  4 boxes per customer and as many cables as will fit in the same box.

International orders received by the deadline will qualify for discounted International USPS shipping (discounted by same dollar amount as equivalent domestic Priority Mail shipping).

The S-BOX and S-BOX-USB are passive serial port splitters that make it easy to connect multiple devices to any compatible transceiver with a serial port.  When connected through the S-BOX, every device can follow the transceiver frequency, automatically changing bands and/or retuning.  "Devices" include:
  1. Elecraft KPA500, KPA1500 amplifiers
  2. ACOM 2000A (with new RCU), 600S, and A1200S amplifiers
  3. SPE Expert amplifiers (all models)
  4. Elecraft KAT500 Tuner
  5. SteppIR SDA 100 and SDA 2000 antenna controllers
  6. Elecraft KRC2 band decoder
  7. Array Solutions RatMaster band decoder
  8. Hamation SM-8 ShackMaster band decoder
  9. 4O3A Interface Genius band decoder
  10. RFSpace SDR-IQ receiver
The S-BOX also includes four independent keying circuits to provide CW, FSK, and PTT to a transceiver via logging software.  A keying circuit can also be used to remotely power up an Elecraft K3, K3S, KPA500, or KPA1500 using RemoteHams RCForb.

The Y-BOX looks similar, but it is not the same as the S-BOX.  The main purpose of the Y-BOX is to eliminate a tangle of 15-pin Y-Cable connections when you have multiple devices that all need to connect to the K3/K3S 15-pin ACC port, including:
  1. KAT500 / KPA500 / KPA1500 AUX cable
  2. Top Ten Band Decoder
  3. FSK keying interface
  4. SO2R box
  5. Remote Rig Interface
The Y-BOX can replace the KPAK3AUX cable kit.  Using the Y-BOX instead of the cable, a K3 macro can power a KPA500 or KPA1500 on or off (this does not work an unmodified KPAK3AUX cable).  The Y-BOX also provides a very convenient way to connect the SteppIR Tuning Relay Interrupt option, which prevents damage to a SteppIR antenna from excessive power while it is tuning.

For photos, wiring details, and the order link, please visit the web sites below. Order any time before midnight PT Monday to receive free domestic USPS Priority Mail shipping:



Thanks, and Happy Labor Day!

Hank:

Well your question posted here is like getting into a bee hive and expecting to find honey.  You will get answers and opinions from many different operators. 

The nice thing about the K3S, in addition to its superior performance,  you can start with a basic radio and upgrade it to your own needs and preferences.  I moved to the K3S from a long history of another US made notable radio brand.  Up until I put the K3S on the desk, I felt that I owned and used a very good performance radio.   Well, I quickly found out the K3S is head and shoulders above the others in performance.   The receiver is super quiet.   The TX and RX audio is excellent.  And I found it to be a radio which I could configure exactly with options to my needs.   It is not loaded with whistles and bells that I don't need.   Thus I am no longer restricted to the "cookie cutter" radios of other brands and models.

With the K3S you won't need the interface for digital and RTTY modes thus eliminating equipment and cables and connectors.   It is handled by a single standard USB cable between the radio and computer.   And as you go to the digital modes, any TX EQ and compression is negated and the correct mode and input is automatically selected.   The values of your choice will be restored when you return to SSB.    Your AL-1200 will drive easily with the K3S.  And you can configure the K3S power output per band so the amp is correctly driven based on the band and drive requirement. 

As to customer support and forward thinking, the Elecraft K3 which is near 10 years old, can be upgraded in hardware to the performance of the current K3S.  With other brands, you'll be lucky to have support for a 10 year old radio,  much less the ability to upgrade the hardware in the future. 

The K3S manual is available for free download on the Elecraft site.  I suggest you download it, print it out and read it.  It discloses what the radio can do.   It is very easy to configure and easy to use.  Menus are simple and in English and not in meaningless acronyms.

With my station configuration, a K3S transceiver, KPA500 solid state amp, and KAT500 ATU, with 2 wire antennas and a 4 element 6M yagi, I can work 160M through 6M with touching anything but the VFO knob on the radio.   Everything precisely follows and in effect  my antenna system appears flat from 160M - 6M,  I run 500 watts just as though I had a 500 watt transceiver, any mode.  And I have only one cable between the radio and computer. 

Note what many to most of the DXpeditions are using for equipment.   There is a reason for that decision.   The Elecraft K3S can deal successfully with the worst of environment, both physical and electrical, and provide outstanding performance under difficult conditions.

KIO3B.   For very weak-signal data modes, the choice of sound cards, along with their various specs, becomes a very important element in the decode chain.  It will be interesting to see what the full specs are, for the card on the KIO3B main board.

Re: K3 upgrade

ve3ki
 

You won't have to use the old line in and line out cables, but you can continue to do so if you wish. If you do choose to remove those two cables and use the USB audio codec in the KIO3B instead, then in your digital mode software you will have to change the sound card settings to use the K3's USB audio codec instead of whatever sound card you were using before, for both transmit and receive.

You will also want to use that same USB connection for an unrelated function, namely radio control from your software. You can do away with any serial cable, KUSB or whatever else you might have been using for radio control, and instead use the virtual serial port that is set up by the driver for the K3's new USB adapter. In the K3's CONFIG menu, change the CONFIG:RS232 setting to USB to enable the USB serial adapter. You will need to change the COM port number in your software to match whatever COM port number Windows assigns to the new port (which you can find with the help of the Windows Device Manager).

The K3S Owner's manual (page 18) contains more information on using the KIO3B's USB port.

I just modified mine with the new synthesizer, KI03B, DVR, and TXCO and now looks and acts like my K3S's. Yep just use the USB for all of your digital modes. Makes thigs a lot simpler. If the factory is doing your mods it will be up to snuff and don't need to worry about that. Your settings for FT8 etc. shouldn't be too far off from what they are. I did all of mine myself and glad I did. I Use it primarily for Field Day but I wanted it to be the same as my other two K3S's.
