Yes, back in the 70's, Yes, I am long in the tooth. One of my friends up north was just getting on the air EME and he had a SUBSTANTIAL station and antenna and started calling, " Hello, hello" and someone answered! he kept it up and then started to listen to the returned signal then he said, " I think I am talking to myself". He recorded it and we all laughed at one on the early West Coast VHF conferences. Those were the days my friends..... Mel, K6KBE

The RTLT is approx 2.5 seconds. But voice is rarely used and emestations rarely operate in Duplex. Of course one can receive yourown reflected signal for a short duration; that is called receiving yourecho. 73, Ed - KL7UW At 03:13 PM 4/9/2017, Mel Farrer wrote: You think that delay issomething try EME. At least there you have a decent delay to getuse 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 itwere. 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. Iwould sound like: hello-ello, how-ow, are-re, you-ou. Say that at anormal 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 beheard. 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 inthe headphones, it does not cause a feedback issue even if the speakers are turned on. However, if one is using low sensitivityheadphones with the speakers turned up high *and* high mic gain, one can cause feedback or echo. Rather than insisting on a change in the waythe K3/K3S operates, one would be better served to repair the issues in his own configuration! 73, ...
