Of all the SoundCard programs for the HAM Radio Digital
modes, we have found FLdigi to be the most versatile
and easy to use. The program is FREE, and supports the
digital modes supported by the BUXCOMM RASCAL’s.
Read the FLdigi Beginners guide then prepare FLDIGI (included on the Free CD) to set up the RASCAL Mk III interface.
Install FLdigi Install FLDIGI to a directory on your C: drive to a folder name: FLdigi or Place all files in this directory on your PC.
Then RUN (double click) on the FLdigi or WimPSK.EXE file).. CLICK on the “SETTINGS” icon, select “GENERAL setup” then
enter your call sign. Be sure the radio button under “SoundCard” by “Use Any Available” is checked. Under PTT Control, select
“NONE” Click OK. Again; under the SETTINGS icon, select Rx Level, set RxLevel & TxLevel sliders to 75% up/open. One of
the SELECT” boxes below a slider should be checked. Click OK Do not check MIC BOOST (ADVANCED) unless the Rx level is
very low. Do not use any PC built-in Microphone when running PSK31. We usually begin with WINpsk (also on the CD) for
a quick test and PSK31 setup, then we install, switch to, and use FLdigi. PLEASE before you begin, read the FLdigi
beginners guide.
NOTE: Transmit Indication is displayed within your PSK31 or other program software. In addition, when connected to your
transceiver, the radio transmit indicators will suffice. Receive and Transmit Audio Levels "TX Level" and "RX Level" are software
adjustable slider controls within your computer sound card driver software. This feature enables receive and transmit control to most
all radio Microphone and Data, Accessory ports. Be sure your transceiver microphone compression is OFF.
