#Cw decoder transceiver software with waterfall code
Hams who purchased it without the intent to learn Morse code will likely inadvertently do so as they continue to listen to the incoming signals, watching the decoding take place, as well as hearing and seeing their own messages being encoded into CW as they type.
With its built in touch screen setup guide, even a greenhorn technician class ham can easily get this rig on the air and making CW contacts in short order. The DMX-40 eliminates a ton of barriers for beginners to start learning CW while making real QSO’s on the air before actually knowing any Morse code at all. For many hams with limited time to play ham radio it’s a tough call between the arduous task of studying CW or immense fun of actually playing ham radio on the air. Non-retired ham radio operators may be very interested but have little time for CW practice between work and taking care of the family. Learning morse code can be an ominous task that deters many hams from even making the attempt. Most will also attribute it to the steady increase in popularity of digital modes such as the infamous FT8. This topic is highly debated but many hams agree that it’s in part due to the introduction of AM/SSB voice communication modes as well as the removal of the Morse code test requirement. The DMX-40 was designed in Sandpoint, Idaho by Eric Anderson, callsign AF7YQ.įor decades, CW communication usage has been in a constant state of decline when compared to other modes and the quantity of licensed hams. It also lets you encode by simply typing your message on the included USB keyboard. It accomplishes this with its built-in ability to decode Morse code without the need for any additional hardware or computer. Please try to ensure you meet the above suggestions and I'm sure that MRP40 will decode with excellent accuracy.The DMX-40 Morse Code Transceiver from PreppComm has the ability to get you on the air operating CW before you know a single character of Morse code. MRP40 works best when "fed" with signal and noise! When testing the MRP40 program don't hesitate to "feed" the program with weak noisy morse signals. To get best decoding result the green bar shouldfluctuate between 10% and 90% of total rangeĬonsequently please avoid overdriving yoursound card's audio input! On the left hand side of MRP40 Program window there is a display of incoming audio level. The AFC is not activated by right-mouse click into the upper window. The Built-in smart AFC (A utomatic Frequency Control ) tunes the signal exactly into the center of CW filter and follows "drifters" automatically.Įach time the recieve-frequency is changed by left-mouse click into upper window the AFC is activated for 4 secondes,- even the AFC Check- Box is in "OFF" state! You might considder to try MRP40 without using any additional (external) DSP. Nearby "interference" signalsare totally suppressed and cannot disturb the decoder. The built-in CW Filter is extremely selective, typical Bandwidth is 30Hz (dynamically adapted to speed) In some cases the decoding result is improved when you switch OFF the AGC of your Transceiver. MRP40 has a built-in Software AGC (Automatic Gain Control) which compensates for all kinds of fading and intermodulation. Tips 'n Tricks essential to get best decoding results with MRP40:
