That post was a direct result of this morning's conversation with Hans (QRP-Labs).?

He has implemented some of the features, but not all.? We discussed methods and

other possible testing approaches.? That conversation was relative to the QSX

transceiver and what it might include.?

Use of a two-line display is limited but if a USB link to an attached PC the display

capability can be increased significantly.? Of course there are other small display

technologies that can be employed as well.?

Computer based testing can be simple or complex.? Faster processors allow more

testing in near real-time, but a lot can still be accomplished with the AVR/Arduino

boards.? Faster processors also allow some DSP-like signal analysis.

Good evening Arv

Hans (QRPLabs) did this with the QCX which includes his own test functions.

• Built-in test signal generator and alignment tools to complete simple set-up adjustments
• Built-in test equipment: voltmeter, RF power meter, frequency counter, signal generator

With the use of the Teensy 3.6 (Jack & Al W8TEE) or STM32 Nucleo microcontrollers, we have enough memory and ports to perform all these settings and tests embedded in a transceiver.

This project on Instructables shows how to build your own "Component Tester".

While it is complete in its own right, it could also be the basis for even more advanced

equipment.

Some of the ideas could possibly be incorporated into Arduino/Raduino controlled

transceivers as built-in test functions.
