User-selected frequency is shown at spectrogram by short red line. maximal deviation from last user-selected frequency. Second number is global deviation in hertzs, i.e. maximal deviation from current frequency. The first number is local deviation in hertzs, i.e. The numbers to the left of the AFC button determines the limits of AFC. The ' AFC' button (auto frequency control) adjusts the long red line (working frequency) to the closest peak frequency. To move a visible part of spectrogram to left or right drag it by mouse with Alt key pressed. ' Alt-7' hotkeys change frequency scale of spectrogram. To change the TX marker position, click on the desired frequency by right mouse button (or by left mouse button with 'Ctrl' key pressed). It is used to help with zero-beat tuning. The short thick black line is the marker of TX frequency.

To change the working frequency, click on the desired frequency (probably a peak). Ruler under this window shows frequencies of sound spectrum.The vertical red line in the top window shows the working frequency of the filter. In the top window the current spectrum of a signal (blue line) and a peak detector of spectral components (green line) is shown. The working area of the program is divided into three windows, the sizes of which can be changed by the user by dragging the borders. Special version for Windows Mobile exists. It is a software morse decoder that really work!

No additional hardware required you need only receiver and computer with a sound card. It can work as narrow-band sound DSP-filter also.

Simple software to handle devices connected to LPT portĪ program to decode morse code (CW) via sound card to text. A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club

To go this way, you’ll need something like the K1EL WKUSB-SMT CW Keyer ().Cluster monitor. In addition, some logging programs, such as N3FJP’s AC Log (), allow you to send CW via a keyer connected to the computer via a serial port or USB port. Another reason is that I’ve had problems with MFJ products in the past and don’t usually recommend them. I have built several K1EL kits, and they are well-designed and well-made. Having said that, I just googled “CW keyboard” and came up with the following: It’s not that I have anything against computer-generated code, but I think sending manually is more fun. Last night I passed my Technician and General exams!!! One question, where would I look to find equipment to send CW with my computer / keyboard?Ĭongratulations on getting your ticket! I don’t do CW by keyboard, and I’d really encourage you to try sending by hand before just jumping onto the keyboard. I just wanted to thank you for your instruction and advise.
