You think that delay is something try EME. At least there you have a decent delay to get use to.

Note that speech able people who lose their hearing slowly also loose the ability to talk properly. If you are hard of hearing you might talk too loud; happens to me on occasion; its just your neural feedback loop doing "human ALC", as it were. For those who operate voice modes on satellites the time delay produced on monitoring your transmission with a full duplex station can get madding. The delay is caused mainly by RTLT (round trip light time) which is the time delay for the signal to travel round trip from the satellite. For HEO (high Earth orbiting) satellites the range gets to a point to experience significant delay in your voice monitored in the downlink Rx. On AO-10/13/40 it could be challenging to talk properly hearing your own voice delayed. I would sound like: hello-ello, how-ow, are-re, you-ou. Say that at a normal speaking rate and you will get the idea what it sounded like. Full duplex operation is quite useful in satellite operating: 1. Avoid talking on top of another station 2. Making frequency adjustment for Doppler 3. Verifying you have an adequate uplink into the system to be heard. Many learned to compensate (mentally disregarding their own voice - which is difficult), or turning down the Monitored audio level when transmitting.

There we agree ... where the monitor level is set to be usable in the headphones, it does not cause a feedback issue even if the speakers are turned on. However, if one is using low sensitivity headphones with the speakers turned up high *and* high mic gain, one can cause feedback or echo. Rather than insisting on a change in the way the K3/K3S operates, one would be better served to repair the issues in his own configuration! 73, ...
