VISIT OUR Ebay STORE FOR MORE ITEM(S) AND OTHER INTERESTING ELECTRONIC PRODUCTS & COMPONENTS   ASM-600W AM C-QUAM STEREO MEDIUM WAVE TRANSMITTER ASM600W is a COMPLETE 19" RACK MOUNTED AM Stereo (Medium Wave) radio broadcasting transmitter, designed with the latest technology digital frequency synthesis (DDS), similar to a PLL but having better frequency stanility than any PLL, providing a crystal clear carrier signal! That offers a noise free, great audio quality up to even 15KHz (complies with AMAX receivers specifications)!   NO NEED FOR CRYSTAL CHANGE, THAT ADD COST TO SET IT ON FREQUENCY! With the DDS frequency programmable synthesizer (based at our ASMAX-1 AM Stereo unit), you don't have to worry about finding and pay extra money to order a specific crystal to set the transmitting frequency of your unit, This is NOT a part 15 AM trasnmitter!   TRANSMITTING FREQUENCY SELECTION MENU FROM DISPLAY! The LCD display will provide the working frequency of the transmitter and all other informations for the menu settings by using only four keys. With 1KHz frequency step selection covers both the 10KHz US and 9KHz EU AM channel spacing while gives the ability to "tune" inbetween of them (ie. for use with older NON digital radios) and by using only four keys you can set menu selectable options as, mono/stereo broadcasting, RF output ON/OFF, etc.  Frequency can be set anywhere inside the AM Medium Wave broadcast band from 530 to 1710KHz (and by request you can have the EU - HAM version that goes up to 2MHz) BROADCASTING TIMER MENU SETTINGS! A unique feature of our ASM-600W AM Transmitter is the user programmable BROADCASTING TIMER SETTING! No other AM unit has this capability! The special menu function is the "ON AIR" TIMER SETTING, with week day/hour/min for powering on & off the RF out. This special menu function can be set by you, to automatically turn on and off your broadcast at specific time on a day or week base! For example if you like to work only during the daytime and shut it down at nightime, you can do that by programming the  ON & OFF time and leave it unattented to work! Basic and user friendly installation! All you have to do is to connect L & R audio and you will send it wirelessly using ie. a whip antenna (see below for more info on antenna construction for Part-15 AM devices). The distance varies with surrounding conditions. The typical RF output PEP power is 600W at 50 Ohm, over the entire band. It is a BROADBAND DESIGN, so no variable caps or coil taps to adjust!   Reception can be on any regular AM MONO or AM STEREO RADIO and you can set easily without any hardware changes (ie. crystal removal) the working frequency anywhere from 530KHz to 1710KHz (special HAM model for 530-2000KHz covering the 160m band) with a step of 1KHz that covers both the US - AMERICAN 10KHz & International 9KHz AM broadcast channel spacing! NOTE: The absolute maximum output power is 680W Peak Envelope Power (P.E.P) is full power peaks with modulation signal at 100% level! The PEP is calculated as ~4 times the UNMODULATED CARRIER POWER on AM transmitters! ASM-600W has a Controller board with a Blue backlited 4x20 LCD and a keypad at the front panel, that offers the ability to easily set all the transmitter parameters, as is the SWR protection power level needed in case of an antenna failure! It has two independently adjustable audio inputs, for LEFTand RIGHT channels with modified 50usec or 75usec pre-emphasis and a 15KHz brick wall low-pass filtering (depending on country). You can change the broadcast frequency on the fly using incremental speed tuning. Just press the UP or DOWN button to go up or down the frequencies. After ENTER is pressed the DDS is re-programmed with the new transmission frequency. The power-on frequency and all other settings can be saved to the built-in non-volatile memory at the press of a key. The unit meets (but it is NOT CERTIFIED) all FCC requirements for AM transmitters of its output level. It has a LPF at he ouput that provides an excellent spectral purity with harmonics rejection better than -60dBc as can be seen in a Spectrum Analyser, out-of-band spurious output better than -70dBc. The accuracy of the lock-on frequency better than +/- 0.2Hz. You can manually turn the RF output on/off, or use the built-in real-time clock to set a daily or weekend schedule for automatic turning on/off the transmitter at a specific time. With this option, one can leave the unit at a remote site and have it operate only for the specified hours.A C-QUAM Stereo encoding system is built-in and provides crystal clear audio up to 15KHz and with a channel separation of more than 32dB. Optionally, this system can be de-activated via a menu selection in case you need to use the device as a standard Mono AM transmitter.The device works at 115 or 230V AC Disclaimer: Although this unit meets FCC requirements for AM transmitters, this does not mean it has been FCC certified.    S P E C I F I C A T I O N S   Frequency Range  530 - 1710KHz (2000KHz under request covering also the 160m HAM band) Min. Step 1 KHz Frequency Drift +/- 0.2Hz maximum. DDS Frequency Synthesizer (better stability than any PLL) RF Power Absolute max 680W PEP (adjustable) No tuning required!

Supply Voltage 120VAC or 230VAC Supply Current 11A  or 5.7A maximum     Harmonic test thru an inline 56db RF attenuation   NOTE: the Antenna connector is a Standard "N" Female For more info on it please do ask us... What about the ANTENNA for AM broadcasting? ASM-600W needs a good 50 Ohm ANTENNA CONSTRUCTION as is for all AM Transmitters The ASM600W will NOT work with a part-15 AM ANTENNA! as is an ISOTRON AM Antenna!    Each unit is FULLY ASSEMBLED, BOXED AND TESTED and comes with instructions. For more info you can ask us!   AM STEREO RECEIVERS Some of the receivers that are capable to decode AM CQUAM Stereo broadcast are the following: Carver TX11 series, Sony STJX220A, ST-JX520A, Sony SRF-A100, Sherwood TD130SB, Jc Penny -Technics MCS3050, Denon TU680, DENON TU-1500, Fanfare FTA100 P, TEAC T30, TEAC T60, METROSOUND AMS400, Kraco ETR-1084, Becker Grand Prix, AIWA CR-S8, AIWA HX-RX626, Yamaha T420A, Panasonic - Matsushita RX-FT53, Panasonic RX-DS15, Panasonic RX-ED57, Panasonic RF-HS70 (the only known digital PLL pocket size walkman type), Aiwa CR-DS805, Sony SRFA300, SRF-AX51V, MEDUCCI AMX-2000, Delco UX-1, Sherwood CRD180, Sansui TU-D99AMX, Sansui TU-S77AMX, Sony SRF 42A, Sony SRF-A1 Walkmans, SONY SRF-AX15, SONY SRF-42, Realistic TM-152, JVC RC-QS11, Pioneer F-D3, Pioneer KE-8003ZH, EUROVOX MCC-6701V,  SONY SRF-M100 (audio cassette size), Aiwa CSD-SR80, Aiwa CR-D60 and hundred other brands and models!   A unique way for receiving CQUAM AM STEREO is the SDR (Software Defined Radio) SoDiRa DE1103DRM that is also capable to receive DRM broadcasts!
