Presently available ham radio sound card software, a RIGblaster, a radio and a computer is the easy and modern way to operate:

• A mic. equalizer/processor up to $250
• A rig control interface up to $130
• A multi mode TNC up to $550
• A contest Digital Voice Keyer up to $180
• A DSP receive filter up to $400
• A receive enhancer up to $170
• A DX beacon clock with receive up to $100
• An Internet remote base up to $ 65
• A sound card interface (of course) up to $140

• Supplied with RS232 and USB interface cables with USB support for Mac (OS9,10), Linux, Windows (98SE - Vista 64)!
• 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.
• Single serial port pass through for radios directly RS232 controlled (newer Yaesu and Kenwood).
• Rig control, FSK keying and sound operation is supported using two serial ports or when using two separate programs.
• 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.
• 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.
• Computer speaker PTT activated mute-on-transmit works with speech processing and for general sound card operation.
• Four ways to connect the receive audio from your radio: direct, mic jack, line out, speaker out. A radio speaker loop jack is included.
• Fully automatic operation; your mic. always works, your computer always works, no manual switching, no plugging or unplugging, ever.
• No extra manual selector switches needed, three DPDT relays for true automatic operation, unlike other sound card interfaces.
• Simpler operation than other brands, you never have to remember to push un-needed switches when operating.
• PTT override feature; your mic. can always override the computer, perfect for contesting or SSTV operation.
• PTT interrupt feature can stop a computer program, our innovation, specially designed for DVK and transmit speech processing.
• Complete with 8pin screw on and RJ45 radio mic. cable compatibility. 4pin screw on adaptor kit as an option.
• Automatic switching between your mic. and the computer; never a hot mic.
• A RIGblaster pro may be connected all the time, everything always works, no bypass switches required. However with the RIGblaster pro power switch in the "OFF" position the process switch must also be "OFF" for your microphone to work through the RIGblaster pro.
• On/Off switch. You mic. works normally with other functions disabled. Other RIGblaster use less than 0.1 watts and do not need an on/off switch.
• 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.
• 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.
• Front panel audio drive control allows setting the transmit audio from the computer to your radio without fumbling with your mouse.
• Dual rear panel RCA PTT jacks provide for a foot switch, amplifier and sequencer connections. This supports our PPT override and interrupt features.
• Total ground loop isolation using 3 shielded isolation transformers, 3 optoisolators, 3 relays and an isolating DC to DC converter.
• Power supply included, no charge. Your choice of 120 VAC or 230 VAC
• 12 VDC operation easily done without the included power supply. See our support page for the proper hookup.

• Supplied with RS232 and USB interface cables with USB support for Mac (OS9,10), Linux, Windows (98SE - Vista 64)!
• Fully automatic operation; your mic. always works, your computer always works, no manual switching, no plugging or unplugging.
• No extra manual switches needed, two DPDT relays for true automatic operation unlike other sound card interfaces.
• Simpler operation than the other brands, you never have to remember to push un-needed switches to make your station work.
• PTT override feature; your mic. can always override the computer, perfect for contesting or SSTV operation.
• PTT interrupt feature; your mic. can stop the computer program, our innovation.
• Complete with 8pin screw on and RJ45 radio mic. cable compatibility. 4pin screw on adaptor kit as an option.
• Automatic switching between your mic. and the computer; never a hot mic.
• You may always leave it connected, everything always works, no bypass switch required.
• In addition to the PTT keying circuit there is a fully isolated CW/FSK keying output for direct keying of your rig's CW or FSK jack for use with non-sound card software, no other interface has this.
• Input for control of this additional fully isolated CW/FSK keying circuit as well as the PTT circuit is jumper selectable between serial port leads RTS, DTR, and TXD.
• Default for this jumper block has RTS controlling the PTT circuit and DTR controlling the CW/FSK keying circuit.
• Internal diagnostic LEDs show at a glance what the serial port is doing with RTS, DTR and TXd, check if the other brand has this.
• Rear panel RCA PTT switch / foot switch jack that enables the PPT override and interrupt, another exclusive.
• Power supply included, no charge. Your choice of 120 VAC or 230 VAC
• 12 VDC operation easily done without the included power supply, an isolated power supply is good ground loop protection however.
