I have assembled a circuit of the work-in-progress "Interactive Frequency Reader" and weighted it: about 90 grams without the CAT cable to the FT-817.
This weight includes the circuitry, the 16x2 LCD and the 4x4 matrix keyboard.
Must not forget to add the enclosure weight too!
The assembled circuit confirms that the hardware design has reached a stable version, as well as basic firmware functions. Now I have to think of a user friendly, menu driven?, interface.
