Reduces or eliminates power line, computer and TV noise by cancelling it before it affects the receiver AGC circuits. Connects between your antenna and radio with a second antenna acting as a noise pickup. Controls adjust signal phase and magnitude from the two antennas to effect noise cancellation. It also can operate as an active antenna using a the noise antenna and noise gain control. And, it can be used as a diversity combiner to pick up enhance weak signals or null interfering signals. 11-16V DC 300 ma. Dim: 1.7"h x 6"w x 4.3"d; 2 lbs............ $209.99 DSP-599ZX Noise Filter Digital Signal Processing provides superior reduction of QRM and QRN. Examines and measures signal and noise correlation, dynamically filtering out undesired noise. Great for VHF/UHF weak signal and aurora work when it can provide a remarkable improvement in clarity to fluttery or distorted SSB signals. Filter settings are displayed on the LCD; Optical encoders for continuous tuning of filters; Data and bandpass filters with steep skirts and linear phase response for CW and RTTY; Bandwidth Range: 10 Hz to 600 Hz; Center frequencies 200-2150 Hz, wider filters allow easy tuning and listening to multiple CW signals; Data filters: RTTY, AMTOR, PacTOR, G-TOR , HF Packet, SSTV, WeFAX, SITOR and CLOVER; Test instrument mode provides audio sine wave generator, audio millivoltmeter and two-tone audio generator for maintenance and set-up of radio audio circuits........................................ $436.99 1275/1275M Sound Card Interface Connect between a transceiver and computer and operate PSK-31, packet, APRS, AMTOR, RTTY, SSTV, CW, HSCW, plus contest voice keying, contest memory keyer, etc. Internal jumpers set up for any radio. Includes AC power supply, all cables and a CD with a collection popular digital mode software. Use model 1275 for 8-pin round microphone plug or model 1275M for 8-pin modular plug (RJ-45)....... each $99.99 1279 Super Sound Card Interface Has all of the features of the MFJ-1275 above, plus: an Auxiliary input jack to switch the sound card to some other device. No more plugging and unplugging. Direct CW/FSK keying jack, headphone jack (use stereo headphones), also turns off external speaker. Plug in a footswitch or other for PTT switch when not using VOX. Plug and play, includes CD with a selection of digital mode software, RS-232 and audio cables, and AC power supply. Use model 1279 for 8-pin round microphone plug or model 1279M for 8-pin modular (RJ-45) microphone plug ........... each $129.99 1273B Sound Card Interface A basic plug-and-play interface for the digital modes. Has jacks for sound card, radio, speaker and RS-232 (no mic jack or switch). Includes RS-232, audio and mic cables and software. No external power needed. Use model 1273B for 8-pin round microphone plug, or model 1273BM for 8-pin modular (RJ-45) microphone plug. ea. $59.99 1272B TNC/Microphone Switch Switch between your TNC and 8-pin microphone by pushing a button. For microphones with 8-pin modular (RJ- 45) plug, use model 1272M ................................................... each $39.99 ARD-9800 Digital Voice and Image Interface Use your conventional SSB transceiver for Digital Voice, Data (3600 bps) and Images while maintaining analog capabilities. No modifications, simply plug it in to the microphone jack, operates with transceiver in SSB mode. An automatic voice signal detector recognizes received signal as analog or digital, automatically switching to the appropriate mode. Uses Open Digital Protocol which is permitted on US Ham bands. Built-in speaker and video output connector which allows external TV monitor viewing. Includes PTT hand microphone, cables and manual. Requires 10-16VDC. Dim: 3.94"w x 1.26"h x 6.14"d .............. $549.99 ARD-9000 Digital SSB Interface Like the ARD- 9800 it works with any existing SSB transceiver without modifications to operate digitally where background noise and static are virtually non-existant and SSB audio is near FM quality. Its Digital Voice only and does not include Data and Images like the ARD-9800; its also less expensive. However, the ARD-9000 and ARD-9800 are compatible with each other and both automatically detect digital signals and decode them while allowing analog signals to pass through. Easily shifts between digital and analog operation. Comes with PTT hand microphone, speaker cable, DC power cable, magnetic mount base and 8-pin microphone plug. Its ready to make the simple connection to your transceiver's microphone input and speaker output. Dim: 2.8"w x 1.3"h x 3.9"d...................... $339.99 Computer SOUND CARD to RIG Interfaces Connect the Sound Card in your Computer to your Rig and operate the Digital Modes: CW, RTTY, SSTV, PSK-31, packet, APRS, AMTOR, High Speed Meteor Scatter, others Digital Voice Interfaces 784B Deluxe Tunable DSP Audio Filter Can simultaneously eliminate heterodynes, reduce noise and interference in nearly any mode. Provides five tunable DSP filters, plus ten programmable filters. An Automatic Notch eliminates heterodynes and Adaptive Noise Reduction reduces fatigue. Highpass/lowpass and tunable bandpass filters combine to dig out weak and difficult signals. Uses 12 VDC or 110V with MFJ- 1312D. Dim: 9.5"w x 2.5"h x 6"d ........ $229.99 Noise Reduction See other DSP Noise Reduction devices by GAP and SGC shown elsewhere in this catalog. We accept I.M.P.A.C.
