The TRX is able to run digital modes and the capability to contact Amateur radio using FT8, FT4, JT65, WSPR and RTTY (Some other modes should be tested). This not a DSB transceiver but a sideband TRX (USB for instance).

2022年4月26日 · The TRX is able to run digital modes and the capability to contact Amateur radio using FT8, FT4, JT65, WSPR and RTTY (Some other modes should be tested). This not a DSB transceiver but a sideband TRX (USB for instance).

In TX mode the signal from the microphone (in SSB mode), from the CW tone generator (in CW mode), or from line-in connector (in FT8 mode), is amplified by the feedback audio amplifier, Q6 and Q7. Further, the modulation signal goes to the DSB (Double Side Band) modulator, made with TR3 transformer and two BAT54 Schottky diodes.

It performs DDC / DUC conversion (digital frequency shift down or up the spectrum) - by analogy with a direct conversion receiver. The I and Q quadrature signals from the conversions are fed to the STM32 microprocessor. It filters, (de) modulates and outputs audio to an audio codec / USB. It also handles the entire user interface.

2019年3月24日 · Adam Rong BD6CR has designed a simple DSB Transceiver for FT8. Crystals are available for 7.074 MHz. and 14.070 MHz (which can be “pulled” with a trimmer to 14.074 MHz). Using only 4 Transistors, 2 IC’s, 3 Toroids, 5 Diodes/LED’s and a handful of resistors and capacitors this one watt wonder will get you on the air in no time.

2023年9月24日 · DL2MAN posted a video with detailed instructions for setting up the (tr)uSDX for FT8 using WSJT-X. Since the (tr)uSDX supports CAT control through it’s USB connector and it has 3.5mm audio in and out jacks, you can use it with a PC for digital modes.

2021年9月26日 · It’s fairly simple, just load AM\CW\SSB Si4735 compatible SDR transceiver firmware into the Teensy micro-controller instead of the FT8 SDR firmware. You will probably also want to add a rotary ...

* This TX is including FSK Capabilities compliant with FT8, WSPR , Rtty and many more * CAT is available for Digital mode * No Rotary encoder since the TRX is controlled by CAT and dedicated for DIgital modes

ADX MINI can work in 11 bands in digital modes optimized HF transceiver that can cover 160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 10m, 12m and also covers four of the most popular digital modes, FT8, FT4, JS8 and WSPR.

Stand-alone FT8 multiband skimmer running directly in WEB-888 or TRX-DUO SDR With today's powerful CPUs built right into the SDR, you can run FT8 decoding without the need for a PC. This option saves considerable money by consuming much less power.
