ADX - arduino digital modes transceiver designed by Barb WB2CBA

I wish to thank Barb WB2CBA for his Kind permission to provide this kit and acknowledge and give full credit for his hard work for designing the ADX

PLEASE NOTE: THIS PRODUCT IS ONLY AVAILABLE TO LICENCED RADIO HAM OPERATORS If stock is depleted please check Jasonkits store !

I have now added another listing where you can order the filters separately. This requires a software update depending on the bands you are going to use it on.

You must include your Callsign when placing your order .

ADX is an Arduino based Digital Modes Transceiver Designed by WB2CBA Barb.

All credit goes to WB2CBA Barb for designing this excellent TRX.

ADX is abbreviation for Arduino Digital Xceiver.

ADX is a mono band (actually quad band) digital modes optimized HF transceiver that can cover four pre-programmed bands one band at a time! It can work on 80m,40m,30m,20m,17m,10m and 15m bands and also covers four of the most popular digital modes, FT8, FT4, JS8call and WSPR. No 12m and 10m bands as it stretches CD2003GP to it’s limits as it is designed for AM band reception. The receiver chip CD2003GP has a much better sensitivity results as it has an RF preamplifier section and a mixer built in.

The ADX is very easy to setup and tune and also operates together with a PC soundcard MIC input and speaker input and ready to operate on any digital modes Software.

The ADX consists of a PA Buffer and R.F output stage and a low pass filter for each band, an analogue chip radio section which consists of an R.F Pre-Amp and Mixer, a SI5351 VFO and an Arduino Nano . Audio Input and speaker output have filters to interface with the Nano.

The ADX has 4 leds for band and mode indication together with a TX Led and three front panel switches to navigate through the various modes.

Supported Bands are: 80m, 40m, 30m, 20m,17m, 15m, 10m

Software Version : 1.6 - added EEPROM protection and 10M band , CAT.

Calibration can be performed using the front panel buttons.

CAT support control trx from the software App

The TRX measures just 97 x 97 mm

Supplied as a kit with all board parts and 1x filter module kit for 20 Meters and 3 bare filter boards
