C-QUAM STEREO MEDIUM WAVE TRANSMITTER NO NEED FOR TUNING WHEN YOU 'RE CHANGING FREQUENCY! ASM60W is a CQUAM Stereo AM Medium Wave radio broadcasting transmitter, designed with the  latest technology direct digital frequency synthesis (DDS) similar to a PLL but having extremely better frequency stability than any PLL, providing a crystal clear, noise free carrier signal! That offers a great audio quality up to 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 of our ASM60W 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, as is with most other, older/used AM trasnmitters available at similar prices on Ebay!   ASM60W works either at AM MONO or AM STEREO and you can set easily without any hardware changes (ie. tuning capacitors) the working frequency anywhere from 530KHz to 1.71MHz!  Has an adjustable output power of 60W PEP (absolute maximum of 70W PEP @ 50 Ohm)! NOTE: The output power is Peak Envelope Power (P.E.P) and that is full power peaks with AM modulation signal at 100% level! The PEP is calculated as ~4 times the UNMODULATED CARRIER POWER on AM transmitters! RF OUTPUT CONNECTOR IS PL-259It has Low Pass Filters to assure that all harmonics are kept below 55dbc for any AM band frequency! The unit meets all requirements for AM transmitters for this power level. It has an excellent spectral purity with harmonics rejection better than -55dBc (even at lower end of band) as can be seen in a Spectrum Analyser. With an internal Forward & Reflected Power bridge connected to a panel meter (as is our FRQM-1 unit, also available at our Ebay listings) you have a reading of SWR and Output power! With this you can even work to adjust your antenna tuner.A complete LPAM C-QUAM Stereo transmitter!The ASM60W works at 115 or 230V AC.   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 1700KHz (and by request you can have the EU - HAM version that goes up to 1999KHz).   BROADCASTING TIMER MENU SETTINGS! A unique feature of our ASM60W AM STEREO Transmitter is the user programmable BROADCASTING TIMER SETTING! No other AM part-15 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 fully adjustable from 5W up to 60W (Note: 70W MAXIMUM) (at 50 Ohm), over the entire band. We have made it with 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 1700KHz (special HAM model for 530-1999KHz covering the 160m band) with a step of 1KHz that covers both the US - AMERICAN 10KHz & EU - International 9KHz AM broadcast channel spacing!   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 all the requirements for LPAM transmitters. It has an excellent spectral purity with harmonics rejection better than -55dBc (out of band) as can be seen in a Spectrum Analyser, out-of-band spurious output better than -80dBc, and 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 35dB. 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. Disclaimer: Although this unit meets technical 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  530KHz - 1.71MHz (covering all the AM broadcast band) Step & Freq drift 1KHz & max +/-0.2Hz (DDS w/TCXO Time base) Zout 50 Ohm RF Power Typ 60W (max 70W) PEP No tuning required!
