This is a small adapter board to use an HC-05 or HC-06 bluetooth serial adapter for a Yaesu FT-100, FT-857, or FT-897. The circuit is exactly the same as the one for the FT-817, just a slightly different mounting method for the LED and Mini-DIN 8 connector. SJ1 is used to provide V+ to the adapter to enable AT command mode on an HC-05. R1-R3 are identical values, and are used to convert the 5v TTL signal from the rig to the 3.3v signal expected by the bluetooth adapter. R4 is the current limiting resistor for using an HC-06, R5 is the current limiting resistor for the status LED for an HC-05. R4/R5 may be omited if you do not desire having a status LED. The voltage regulator is a AMS1117-3.3v or LM1117 3.3v regulator. This board is designed to go straight off the back of the radio and not interfere with any other ports. This board WILL NOT fit on the FT-817 when it is standing on it’s back feet, although otherwise it will work. When ordering this board, order it in the 2oz, or it may not fit between the connector’s pins.

This is a small adapter board to use an HC-05 or HC-06 bluetooth serial adapter for rig control of a Yaesu FT-817. SJ1 is used to provide V+ to the adapter to enable AT command mode on an HC-05. R1-R3 are identical values, and are used to convert the 5v TTL signal from the 817 to the 3.3v signal expected by the bluetooth adapter. R4 is the current limiting resistor for using an HC-06, R5 is the current limiting resistor for the status LED for an HC-05. R4/R5 may be omited if you do not desire having a status LED. The voltage regulator is a AMS1117-3.3v or LM1117 3.3v regulator. This board is designed to be able to be left on the radio, even when it is standing on the back end, and not interfere with any other ports. Please note that the FT-817 leaves the port powered at all times, so it may be advisable to leave the LED off if concerned about power consumption. The bluetooth adapter itself is rated to consume 10mA while actively paired, and 30mA while disconnected, according to the datasheets I have seen.

This is an LED indicator board that is designed to go on top of the breakout board I previously designed.

This board is to break out the single connector on the CAT-1000 repeater controller to two discrete radio ports. Both ports are wired the same, with pins 1, 6, 8, and 9 as ground, 2 for PL in, 3 for PTT out, 4 for TX Audio, 5 for RX audio, and 7 for COR. For those with both a RLC CLUB Deluxe II repeater controller, this is the same pinout. This was simply put onto a board to ensure all connections are properly made, and reduce the likelyhood of them coming loose in operation. The schematic for this board may be downloaded here
I have also designed an indicator board that may optionally be stacked on top of this one to provide diagnostic LEDs for the status of the digital lines on the two radio ports.
