Converts the 12-pin Molex pico-blade connector to the 4-pin individual power detector board format. 5V to 3.3V regulator on this board to prevent voltage drop to couplers (35 mA each).

DC board pinout for RF from DUTs to connect to Power detector board for Output power from DUTs.

Donkey Bounce Shield

NOT YET TESTED Onboard Raspberry Pi power supply, three MAX31850 Thermocouple Digitizers, one DS18S20 and an Alert Buzzer. Board is designed with Kicad. Check Github for the KiCad design files.

Project: https://github.com/rfrht/FT991A-PAT

This project is a remix of OE2DOR’s perfect and neatly crafted FT-991A Panadapter board.

The final objective is to actually embed a RTL-SDR inside a FT-991 (or FT-991A), without drilling holes, external cables, connectors or whatsoever: The FT-991A sports a USB hub (which feeds the sound card and the CAT interface). By replacing the existing 2-port USB hub chip with a 4-port variant (same SMD footprint and compatible pinout), the SDR will be installed in the radio, and it will be exposed to the computer via the existing USB port, conveniently routed through the radio’s USB hub. So, plug the radio’s USB port and the computer will see three devices: the virtual sound card, the CAT port and the SDR.

This fork adds on-board latch control, by using a AND gate with two inputs that controls a RF switch: The IF signal is only connected to the SDR if both signals (on my project, a SDR GPIO signal and the RX9 signal from radio’s Main Unit) are present. Otherwise, the SDR is left isolated to the ground and no signal is tapped.

BOM

1.1 Changelog:

• Added indicators for the chips and header to make the pcb easier to assemble

• Added indicator for LED positioning

• Reduced pcb height by 0.3mm

• Fixed positioning of cartridge reader guide holes

• Renamed IC1 and IC3 to make more sense

1.2 Changelog:

• Reduced pcb height by 1.4mm

• Relocated componetnts to fit within the new size

• Modified footprint for cart reader

• Replaced the crystal (ECS-60-32-5PXDN-TR) with FQ1045A-6.000 to as this component is only 1.7mm tall instead of 4.3mm
