  • Any radio that has an RJ45 modular telephone style connector
  • Any radio with RJ25 6 wire microphone connector with the purchase of an optional FT100 style 6 wire modular mic. cable
  • Any radio with 4 pin round microphone connector with the purchase of a optional 4 pin mic cable

Computer Interface

  • Supplied with both a standard DB9 RS232 serial cable and USB cable interface (supported for Mac (OS9,10), Linux, Windows (98SE - Windows 11)! May be used old or new computers with your choice of USB or RS232 DB9 serial

Built-in Rig Control

  • Built in rig control, RS232 to TTL interface tested with Icom and Yaesu; compatible with Ten Tec
  • Rig control is possible along with sound card PTT control and CW keying on a SINGLE serial port using Hamscope or MixW software
  • Rig control, FSK keying and sound operation is supported using two serial ports or when using two separate programs

True Keyed CW

  • Fully isolated CW keying output for direct keying of your rig's CW. This jack is for use with non-sound card software using serial DTR control.
  • Fully isolated FSK keying output for direct keying of your rig's FSK jack. This jack is for use with non-sound card software using serial TXD control

Maximum Mic/Keying/Audio Flexibility

  • Four ways to connect the receive audio from your radio: direct, mic jack, line out, speaker out. A radio speaker loop jack is included
  • Dual rear panel RCA PTT jacks provide for a foot switch, amplifier and sequencer
  • Front panel audio drive control allows setting the transmit audio from the computer to your radio without fumbling with your mouse
  • Your microphone may be bridged to computer as well as radio for on-the-fly digital recording
  • Transmit speech processing is done by looping mic. audio through the sound card using appropriate EQ and compression software. Voice Shaper by VE3NEA is an amazing free program for this
  • Plug in 2nd mic. jack allows instant automatic switch over to a headset mic. without unplugging your main mic
  • Both 1/4" and 1/8" front panel headphone jacks to monitor computer receive and transmit audio; no searching for adaptors. These connections facilitate using DSP receive audio software
  • Computer speaker PTT activated mute-on-transmit works with speech processing and for general sound card operation
  • PTT override and interrupt enables mic to override the computer or stop the computer program, perfect for contesting or SSTV operation
  • Front panel LED indicators show whether computer audio or mic. audio is routed to the radio
  • Front panel LED indicator shows if the computer audio is present at an adequate level for transmit or receive
  • Front panel LED indicators show PTT, CW and FSK activation status making it easy to check the operation of your software


  • Assembled in USA to IPC-610 manufacturing standards.
  • Printed circuit board uses FR4 material, double sided, plated through holes, solder mask over bare copper, silk screened
  • Enclosure: .062 aluminum, polyurethane painted, silk screen labeling front and back
  • 3M Bumpon™ protective feet and 3M™ adhesive pads are provided for mounting
  • Toggle switches: 50,000 make and break cycles, 2 amps 250 VAC
  • Stainless steel hardware throughout including PEM™ threaded mounting standoffs

The microphone audio is completely isolated from all other grounds. The three sound card audio signals are isolated using three audio transformers. The computer is isolated using, three DPDT relays, three opto-isolators and a isolating DC to DC converter. A high grade DC blocking capacitor is on the sound card to mic. output for use with radios that are designed for use with amplified or electret microphones.

The relays provide adequate current and voltage capability to switch tube rigs. The relays also provide automatic switching between sound card audio, transmit muting and our mic. override and mic. interrupt features.


Additional/Replacement DVD for RIGblaster Products

A DVD of the RIGblaster Software Collection is the standard media. If you are unable to use DVD media, you may request the software on a two (2) CD Set. When ordering online, in the comments section of the order form, type in "Request 2 CD Set". Alternately, the collection of software programs may be individually downloaded here.
