INTRODUCTION The MFJ-9200 is a bold new addition to MFJ's legendary QRP transceiver line, delivering unmatched 6-band CW performance in a compact pocket-sized package. QRP radios have always been small in size, but thanks to direct-digital synthesis and microprocessor technology, the MFJ-9200 represents a quantum leap over traditional designs with an unprecedented number of features at an affordable price. The MFJ-9200 covers 80 through 15 Meters with computer-modeled plug-in filter modules that yield no-compromise receiver performance and QRP+ transmit power on every band. There's also built-in iambic keying with a manual-key sensor, a programmable CQ message, and seamless QSK T/R switching. DDS frequency control delivers rock-solid VFO stability, precise 100-Hz readout, and eight memory channels per band. Plus, you get a choice of three main-dial tuning rates and RIT with 10-Hz tuning resolution. Other features include selectable IF-bandwidth for monitoring SSB or CW, a 20-dB front-end attenuator for overload protection, and a switched backlight for the LCD display. There’s also plenty of receiver overlap for monitoring time signals and international short wave broadcasting. The MFJ-9200 runs on any power source between 8 and 15 VDC and draws 40 mA on receive with the display backlight turned off -- perfect for prolonged off-the-grid adventures. Best of all, the MFJ-9200 is the smallest and lightest backpack transceiver currently available. In order to take full advantage of the MFJ-9200’s many operating features, please read this manual carefully before attempting to set up and operate your QRP station. The MFJ-9200’s microprocessor controls are surprisingly simple and intuitive to operate with only a minimum of familiarization. Nevertheless, as with any electronic device, failing to follow the prescribed set-up and operating instructions could result in permanent damage. Once you become familiar with basic setup and operating procedures, feel free to use the Quick Menu in the back of the manual as a refresher. Important Warning: Before attempting to operate your MFJ-9200 on air, please read through the entire manual. Failing to adhere to prescribed setup and operating recommendations could result in permanent damage to your radio!

DO NOT connect the MFJ-9200 to a source exceeding 15 VDC or permanent damage may result. Power Connection: Use a standard 2.1-mm concentric power plug with plus (+) connected to the center and ground (-) connected to the outer sleeve. The MFJ-9200 has a built-in series diode to protect against accidental reverse-polarity connection, but we also strongly recommend fusing the plus (+) lead of your power source at 2-A to provide over-current protection in the event of an accidental short or component failure. + _ 2-A Fuse 2.1-mm Plug Antenna: The antenna jack accepts a standard BNC male connector or BNC-to-UHF adapter, as required. Connect any coax-fed resonant antennas with SWR measuring under 2:1 directly to the radio. Antennas exhibiting higher SWR or using balanced feeders should be matched to 50-Ohm unbalanced line using an external antenna tuner (ATU). Never intentionally transmit into high-SWR loads, as extreme mismatch may cause the radio to emit out-of-band signals exceeding FCC guidelines. A prolonged high-SWR condition may also damage internal components. Headphones: Use any 8 to 32-Ohm stereo headset outfitted with a 3.5-mm stereo plug. Note that the radio’s audio output circuit is not wired to accept monaural plugs. Connecting phones or a speaker wired with a monaural plug will shunt the audio signal to ground. To obtain monaural output, use a 3.5-mm stereo plug and leave the ring disconnected. Stereo Phones Sleeve Right Left Ground Ring Tip Audio NC Ground Monaural Phones Sleeve Ring Tip Paddle or Straight-key Wiring: Configure paddles with a 3.5-mm stereo plug. Connect the dot contact to the tip, dash contact to the ring, and ground to the sleeve. Configure manual keys using a monaural plug with the contactor connected to the tip. If using a stereo plug with a manual key, connect both the ring and sleeve to ground. Paddles Sleeve Dot Dash Ground Manual Key - Monaural Plug Sleeve Ring Contactor Tip Ground Manual Key - Stereo Plug Sleeve Ring Contactor Tip Ground Ground Tip TRANSCEIVER OPERATION Installing Band Modules: Prior to powering up, identify and install the filter module for the band you intend to use. The band is marked on the filter pc board. To access plug-in headers for the module, remove the two knurled screws securing the radio’s case and slide off the back. Antenna Antenna Module Header Module Screw Standoff Module Header Band Label Band Module The band-module headers are located directly below the BNC antenna connector. Line up the module and install it component-side down, as shown. Fasten in place using the module retention screw and reinstall the case. Note that the retention screw should always be used to ensure firm seating and good grounding. Also, note that a filter module must be installed for the DDS to recognize a band of operation. Key Detection: The MFJ-9200 features a key-detection circuit. The sensing circuit initializes each time the radio is powered up. If paddles are connected or if no key is installed, the keyer initializes in Automatic Mode and sends the letter A in code. If a straight key is installed when the radio is powered up, the keyer senses Manual Mode and sends the letter M. Important Note: The radio’s default is Automatic Mode. If a manual key is plugged in after the radio is powered up, the radio will transmit a continuous string of dashes until the key is unplugged or the radio is rebooted. This condition occurs because the keyer misinterprets the manual key’s monaural plug as a ring-to-sleeve contact closure. To correct it, simply switch the power off and turn it back on again to re-initialize the keyer. Power On: After connecting a power source, antenna, headphones and key, you’re ready to begin. It may prove helpful to have your radio set up and connected to a dummy load when going through this portion of the manual so you can check out each function without causing on-air interference. Using the POWER switch located on the front panel, power up the radio and set VOLUME for a comfortable listening level. Boot Screen: During power-up, the LCD screen displays the selected band. Example: [Band-20m]. Also, the keyer side-tone sends the letter A or M in code to identify the type of key that is plugged in. Operating Screen: After two seconds, the boot screen switches to an operating screen that displays the following information: (1.) Upper-left: Shows IF bandwidth [CW] or [LSB]/[USB] (depends on band in use). Every four seconds, this readout momentarily switches to show power supply voltage. Example: [12.6]. (2.) Upper-right: Shows VFO status. A [V] means the tunable VFO is active and [M] indicates the Memory Mode is selected (see MEM-VFO). The adjacent number [1-8] shows the current memory channel. When power is applied, the radio comes up in Memory Mode [M]. (3.) Lower Line: Shows the radio’s active operating frequency for the VFO or memory channel. Resolution is normally 100-Hz, but diverts to 10-Hz when the RIT is activated. Band Error: If no filter module has been installed, the display will flash [BAND-???] to alert you that a module needs to be installed. Transmit Error: If the transmitter is keyed while the VFO is tuned outside the amateur band, the top line of the display flashes [TX ERROR] and transmission is blocked. Push-Button Controls: Front-panel switches control most transceiver functions. There are five red pushbuttons plus a momentary push-in switch built into the TUNE knob. Four switches activate more than one function and require two types of user input. The primary switch-input is a momentary press. The secondary switch-input is a two-second press and hold. The manual instructions are “tap” for a short input and “depress” for a long input. MEM-VFO Switch: To toggle between VFO and MEMORY, tap the MEM-VFO switch. In Memory mode, [M] is displayed and the TUNE knob is used to scroll through the channels. The radio normally boots up in memory mode. In VFO mode, [V] appears on the display and the TUNE knob changes operating frequency. Note that the number of the most recently selected memory channel [1-8] is displayed in both the VFO and Memory modes (many synthesized radios and HTs use a similar VFO/Memory setup). To load a VFO Frequency into Memory (VFOÆMem): [ ] Tap MEM-VFO to [M] and rotate TUNE to select a desired memory channel [1-8]. [ ] Tap MEM-VFO to [V] and rotate TUNE for the exact frequency you wish to store. [ ] Depress MEM-VFO to move the VFO frequency into memory. [Save] confirms completion. To retrieve a Frequency from Memory (MemÆVFO): [ ] Tap MEM-VFO to [M] and rotate TUNE to select the memory channel you wish to recall [1-8]. [ ] Tap MEM-VFO to [V] to transfer it into VFO mode. You may now tune up or down the band. [ ] To update the original stored frequency with a new frequency, depress MEM-VFO. [Save] will flash on the display to confirm completion. If you don’t save a new frequency, the original entry will be retained in memory. TUNE Switch: The TUNE knob has a momentary press-down switch for selecting tuning steps. [ ] To toggle between 100-Hz and 1-kHz tuning steps, tap TUNE. The frequency display momentarily underlines the tuning increment you select [ _ ]. [ ] To select 100-kHz tuning steps for rapid QSY between band segments, depress the TUNE knob. After shifting band segments, depress TUNE again to restore normal finetuning. RIT-MODE Switch: Activates RIT function, plus controls bandwidth and sideband selection. [ ] To use incremental tuning, tap RIT to toggle it on and off. When active, the frequency display shifts to 10-Hz resolution and a dash symbol [-] appears to the right of the last digit. The dash symbol [-] signifies zero RIT shift. Rotate TUNE clockwise to move above zero-shift and note that an up-arrow [↑] appears on display. When tuning below zero shift, [↓] appears. To restore zero-shift, tune opposite the arrow until the dash reappears [-]. The normal RIT tuning step is 10 Hz. [ ] To select bandwidth, depress MODE to toggle between narrow [CW] and wide [LSB or USB]. The processor selects the appropriate sideband designation, depending on the band. ATT Switch: Tap to toggle the attenuator on or off. Receive attenuation is approximately 20 dB. BL Switch: Tap to toggle the display’s backlight on or off. Off conserves power when operating on batteries. CALL Switch: Initiates an automatic CQ. Also selects several keyer setup functions. Keyer setup functions require connecting a set of paddles to the radio. [ ] Call CQ: Tap CALL. The keyer will automatically transmit a complete CQ sequence, inserting the call letters that have been programmed into memory. [ ] Adjust Keyer Speed: Depress and hold CALL until you hear the letter S played back in code. Release CALL, and within five seconds, press and hold the DOT paddle to increase speed or press and hold the DASH paddle to decrease speed. The sidetone provides audible feedback as the speed changes. When a comfortable rate is found, tap CALL once to exit. The letter E confirms completion of the programming sequence. [ ] Enter Your Call into CQ Memory: Depress and hold CALL until you hear the letter I (which will follow S by a few seconds). When you hear I, release the CALL button and send your call letters in normal fashion using the paddles. When finished, tap CALL once to exit. [ ] Test Carrier: Depress and hold CALL until you hear the letter T (follows S and I). When you hear T, release the CALL button and press the DASH paddle to initiate a continuous carrier. Press the DOT paddle to turn it off. To escape from Transmit Carrier mode, tap the CALL button. The letter E will confirm your exit. The Test Carrier function allows you to lock the key down when using paddles to take SWR readings or make tuner adjustments. TRANSCEIVER CARE AND MAINTENANCE The MFJ-9200 has no internal “user” adjustment and is designed to be maintenance free. To preserve the finish, avoid using harsh chemical cleaners on the cabinet or on plastic parts. When backpacking or boating, keep the radio dry by sealing it in a Baggie or Pelican case during transport. If it should become wet, remove the back of the case and allow all circuitry to dry out for an extended period before powering up. Do not power up if you observe condensation in the LCD window, and avoid heating at high temperature to accelerate drying. Better to seal it in a container with a desiccant capsule to draw the moisture out at room temperature. TECHNICAL ASSISTANCE If you have a problem with your radio, first check all external plugs and cables for shorts or opens and confirm that your antenna is working properly with low SWR. Also, check the operating voltage of the power supply or battery pack and review the radio’s various functions to confirm that you haven't inadvertently reset a critical operating parameter. If the problem persists, you may call MFJ Technical Services at 662-323-0549 or the MFJ Factory at 662-323-5869.
