I've developed a small interface board for the HAMWARe controller AT-502, AT-515 and AT-651B. This interface boards supports RS232 and CI-V communications and can be directly mounted into the controller chassis.

You may have seen my build version of the M0UKD sensor keyer and the Bamatech sensor head.

As you can see in this post, I've used a simple slide switch to control the power for the sensor keyer. This was a little bit annoying, as you must always check, whether you've turned of the power, when you leave the shack.

As power consumption is not really a big issue - the keyer draws about 2.5mA from two AA-cells. Based on the capacity of an average Energizer Classic AA battery of 1.200mA you will get an on-time of about 300h.

Since many months I've had the idea, to add an electronic switch to the keyer, so it switch of automatically after 15 minutes of idle time.

The Nextion display needs the content defined in the file PowerMeter.HMI. You can either upload it with the Nextion editor via a serial link to the display or you can copy the TFT file to an SD card and put this into the socket on the Nextion display.

I've updated the the display control files to the current Nextion Editor 1.62:

Die Orignal-Firmware des Steuergeräts des HAMWARE Tuners AT-502 hat eine Funktion eingebaut, welche an Hand eines gesendeten Trägers versucht die aktuelle Arbeitsfrequenz zu ermitteln und den dazu passenden Speicher auszuwählen.

Dies funktioniert bei CW relativ gut, im SSB Betrieb ist dieses Verfahren nicht optimal. Der größte Nachteil meiner Ansicht nach ist aber, dass man zuerst einer Träger senden muss, damit die Frequenz eingestellt wird.
