This allows the FUNcube to be physically separated from the computer (reducing RF ingress) and also takes some of the strain off of the USB connector. The FUNcube Dongle can be attached directly to the computer's USB port, but some operators have reported that it's better to use a short USB extension cable. Verify (again) the FCDPP demodulates signals.Download FCHid (called FCD+ Frequency Control Program v2.002).
#HOW TO USE JT65 INSTALL#
Read the user manual for the FUNcube Dongle Pro+ (FCDPP) and install the software according to directions. It helps to disable power saving options on the computer used to run the SDR. These instructions are written with the Windows 7 operating system in mind. It should, however, provide a good starting point.Ī reasonably fast computer is required, and modern multi-core processors should be fine. The configuration settings described below will likely need to be optimized if station hardware differs significantly from the above. If separate transmit and receive lines are not used, careful attention needs to be placed on protecting the FCDPP receiver from damage during transmit.
#HOW TO USE JT65 1080P#
Second 1080p monitor (optional, but recommended) Multi-Core CPU (MAP65 is more CPU intensive than WSJT) Traditional transceiver and WSJT9 software SDR (in this case, the FUNcube Dongle Pro+) A/B coaxial RF relay in shack (low-power) A/B coaxial RF relay at mast (high-power) I also found it helpful to add a dedicated coax relay to switch the input of the splitter to a 50-ohm dummy load during transmit this also helps to prevent spurious JT65B decodes. The FunCube Dongle Pro+ is connected directly to the output of the splitter, the other port goes directly to the analog radio.Īppropriate coax relays are controlled by a dedicated sequencer and protect the mast-mounted preamplifier and switch between the separate TX/RX lines. Mini-Circuits ZFSC 2-2 Power Splitter, 10-1000 MHz). Received signal is sent through a separate receive coax (75' of RG-8/U) to a hybrid splitter combiner (ie. For my 144 MHz EME, I use two M-Squared (M2) 2M7 antennas coupled with a M2 power divider, feeding an Advanced Receiver Research (ARR SP144VDG) GAsFet premplifier with +24dB gain. It assumes that the operator is already familiar with EME exchanges using the JT65B protocol, has experience with WSJT software, and has basic EME station hardware.Ī typical EME-capable station will have a mast-mounted preamplifier, sequencer, and separate transmit and receive lines.
#HOW TO USE JT65 HOW TO#
This article describes how to install a FUNcube Pro+ (FCDPP) software defined radio (SDR) into an exisiting EME station. This can be a great benefit to both small and large stations, since monitoring the entire spectrum simultaneously will tell you exactly where other EME stations (strong enough for your system to decode) are located. A software-defined receiver coupled with MAP65 software will allow the amateur radio EME (Earth-Moon-Earth) operator to visualize the entire EME sub-band at once.
