ATU Port Expander
he ATU Port Expander is a device that attaches to a Multus Basic or Proficio transceiver’s ATU port, interprets band data sent to it and selects a corresponding output port for the activation of relays (or other devices) such as a low pass filter relay(s). It also provides a separate output port for the activation of a two port remote antenna switch such as the MFJ-4712 (via a bias tee). Each output port is capable of sinking 350ma and has a maximum input voltage of 50V. The ATU Port Expander is well suited for driving inductive loads (relays).

Features:
*Compatible with ATU port of the Basic and Proficio transceivers.
*Six output ports (50V maximum voltage, 350ma per port).
*Separate antenna switch port.
*Port selection configuration via selection jumpers.

The ATU Port Expander is sold as a kit and contains SMT devices. A bare bones option is available that provides the PCB, programmed microprocessor and socket. A bill of material is available on our support forum.

SMSG (S Meter Signal Generator)
The SMSG (S Meter Signal Generator) is device that generates a selectable S9 or S4 signal in one of 4 selectable bands. The SMSG is useful for calibrating the S Meter of any receiver or transceiver. It is particularly useful for calibrating the S Meter of a SDR application such as HDSDR or GSDR and others.

Specifications: Output Impedance: 50
Output Level: S4:1.6uV (-103dBm), S9:50uV (-73dBm)
Amplitude Accuracy: S4: +/- 3dB, S9: +/- 3dB
Output Frequency: 80M (3.686MHz) +/- 30ppm
40M (7.040MHz) +/- 50ppm
30M (10.116MHz) +/- 30ppm
20M (14.070MHz) +/- 30ppm

The SMSG is sold as a kit and contains SMD devices. It is easy to build and will take about 2 hours for an experienced builder.

UIA (USB Isolation Adapter)
The UIA (USB Isolation Adapter) is a USB 2.0 (Full Speed, Low Speed) compliant device that provides complete isolation of a down stream USB device from the up stream host computer. Ground loops are eliminated. Host computer or device generated common mode noise and RF induced noise is significantly reduced or eliminated. It also provides 5000Vrms isolation between the host computer and the down stream device. Also 8KV of ESD protection is provided. The UIA provides these benefits using a number technologies.

1) An Analog Devices ADuM4160™ USB Digital Isolator provides USB isolation.
2) RF chokes are implemented on all voltage supply lines.
3) Separate ground planes have been implemented for both the up stream and down stream.
4) Power for the up stream and down stream devices are completely separated and independent.
5) 8KV ESD protection devices are attached to the USB data lines.

The UIA works with any 2.0 USB Full Speed or Low Speed device. It is the solution for USB connections that suffer with ground loop or noise problems.


The UIA is sold as a kit and contains SMT devices.

IQBD (IQ Balance Detector)
The IQBD (IQ Balance Detector) is a device to aid in determining the correct balance of the IQ audio signal sent to a Multus SDR, LLC. transceiver. Most transceivers (including the Proficio) that implement Tayloe mixers to generate the transmitted RF signal may need small adjustments to the balance of the two channel I/Q audio signal provided to the transceiver. If the I/Q signals are too far out of balance, an image signal is produced in the transmitted RF signal. MSCC configures a default set of I/Q values for each transceiver version.  The default values set the I/Q balance well within the limits for spurious radiation. However due to minor variations in assembly of the transceiver, the I/Q balance may not be optimal. With I/Q calibration, the image signal can be reduced to well below 60db below carrier.

Determining the strength of the image signal is often performed by listening to the transmitted signal on a second receiver or transceiver. The IQBD eliminates the need for a second receiver or transceiver.

The IQBD also serves as a general purpose 50Ω dummy load.  Maximum input power is 10 watts.

Features:
  1. Highly sensitive to IQ out of balance conditions.
  2. LED IQ balance visual indicator.
  3. Audio IQ balance output indicator.
  4. 10W maximum input power.
  5. Powered 13.8V supply or 4 CR2032 Button Cell Batteries (supplied).

The IQBD is sold as a kit and contains SMT devices.

MFC (Multi Function Controller)
The MFC (Multi Function Controller) is an optional accessory for the Proficio Transceiver.  It provides a more transitional method to operate the transceiver.  The MFC is easy to build and install. 
Features include:

  • 16x2 Display.  Displays frequency, switch function, operating mode, frequency step and transmit On/Off.
  • Three function switches.
  • Multi function tuning knob.  The knob may be configured to change frequency, volume or RIT offset. 
  • Tuning knob push button switch.  The tune knob has an internal switch that may be configure to control one of the various available functions.
  • Twelve operating functions.  A function may be assigned to any of the four control switches. The currently implemented functions are:
  • Frequency step,PTT On/Off ,TUNE On/Off,MODE Selection,RIT On/Off, Band Selection, Frequency/Volume control, CW Bandwidth, High Pass Filter Selection, RIT Tuning, Favorites Selection and No Function.
  • Individual connection for PTT.  This is convenient for attaching a foot activated PTT switch or other type of switch for activating PTT.

NOTE: The MFC is compatible with Proficio PCB versions 5.x, 4.x and REV C (with a minor wire change).

NOTE: This product contains the MFC components only. The enclosure may be obtained online from a number of suppliers.  Listed below are the part numbers for ordering the enclosure from Digi-Key or Mouser.  The approximate cost is $45.74 (plus shipping).
