I have tested the Dittel / TQ KRT2 radio with LK8000 Ver. 6.3 c together with the OpenVario. I use the native Dittel KRT2 driver at 9600 baud / 8 bit and tested several serial ports, which behave in the same way. I have a bidirectional communication established and can see changes made at the KRT2 frontpanel appearing in LK8000 and vice versa. For most airfields which I select in LK8000, the frequencies are set correctly at the KRT2. For some airfields (e.g. Michelstadt, Frequency 123.650) LK initially displays the correct number, but KRT2 shows 123.135. After a while (approx. 5-10 seconds, sometimes after minutes) LK8000 displays the same frequency as the KRT2. Obviously LK reads back the frequency from KRT. It looks like there is an (unidirectional) transmission problem from LK to KRT under some circumstances. It could also be a hardware issue of the KRT2 (although brandnew). This strange behaviour seems to be reproducable. The same applies, if I enter a frequency digit-wise in LK8000. Examples:
LK8000 entered frequency -> KRT2 displayed frequency
122.700 -> 122.185
120.300 -> 120.040
120.400 -> 120.140
120.500 -> 120.240
120.600 -> 120.085
120.700 -> 120.185
120.800 -> 120.030
I configured the KRT with both, 8.33 / 25 kHz channel spacing and 25 kHz only, but no effect. I also erased the frequency list in the KRT2 to avoid any kind of suspicious interaction, but also no effect. Is there a possibility to create a logfile with the (native) communication? Any help of the experts would be highly appreciated! Thanks in advance...

Dieter

It is a known signed/unsigned problem already solved in 6.3f

Could this be anything to do with the fact that what you enter using 8.33 looks like a frequency, but isn't.

Hi Giancarlo,

Did you connect your KRT2 to the Oudi? How did you do that and what cable or connector are you using?

Best regards,
Rob
