QDX on 17 and 15 m: Receiver

I got myself one of the marvellous digital transceivers from QRPLabs recently: The QDX - QRPLabs Digital Transceiver. It is set up with receiver bandpass filters and transmitter lowpass filters for 80, 40, 30, and 20 m. It has also been found that the 40 m filters work well for 60 m. 

The latest firmware, version 1_04, has a new "Band Configuration" screen where one may configure the list of supported bands. It is the intention that higher bands will eventually be supported.

I am not so interested in 80 m, so I wanted to see if I already now could get the receiver to work on 17 m and 15 m. With reference to the schematics, I modified the input filter's inductor, L12.

The multi-face Arduino GPS clock is inspired by the Clock Kit from QRPLabs. It is an open source project on GitHub, and it now has support for many more languages in the newly released versjon 1.4.0. As a language nerd myself, I love fiddling with multiple languages and character sets.

The local language option is for display of day name in case local time is shown. The default is English for local time. No matter the choice for local time, English is always used for UTC day name. Here are examples:
