I have the pleasure to distribute the following freeware programs :



TRX-JUMA is a stand alone free software (freeware) for the JUMA TRX2 Transceiver. TRX-Juma is ditributed with the TRX-Manager's demo and requires the same runtime. Please download and install the TRX-Manager' demo and run TRX-Juma.exe (no registration required). Of course JUMA TRX2 is also fully supported by TRX-manager.

Basic instructions :

- Warning: firmware 1.07w Build 10 or later by Adran 5B4AIY required.
- Power on your JUMA TRX2 transceiver
- Config your JUMA TRX2 for RS232: JUMA TRX2 and VFO: A/B + Split
- Click first CONFIG to set up your computer (Port, Speed, Baud Rate)
- Click PWR to engage CAT Control (do not use PWR to power on the transceiver, this is not supported by the firmware)
- the behavior of the buttons may slightly differ from the JUMA TRX2's Front panel

The initial purpose of MATH4DSO was to communicate with an Agilent/Keysight X-Series oscilloscope and to calculate and display improved FFT spectrograms. Many functions have been added to use MATH4DSO as a control program for the oscilloscope itself. MATH4DSO can display the digitized signals and provides basic functions to control the oscilloscope from your computer; this part of the program may be improved in the future. More information...
