What is the "official" position w.r.t. solutions that provide only simplex operation where the operator cannot listen to his own signal when transmitting?
In my experience with older high-orbit satellites it is really required to be able to listen back while talking, even when it can cause annoying problems due to the path delay (stuttering or slow talking), so when doing anything but calling one would turn down the volume on the receive a bit while talking.
However, with equipment that is inherently unable to receive while transmitting, it will be very difficult to judge if the signal is above the beacon, if the LEILA2 system is acting on it, and (when the station is not perfectly calibrated) if one is transmitting over someone else.
I think it would be recommendable to always have the capability to receive while transmitting in the transverter design ("full duplex" operation), and maybe this should be stated in the operating recommendations?
I understand the attraction of having a simplex transverter that could e.g. be used with a single FT-817 to form a portable station, but IMHO it will be very limiting to have no possibility to monitor one's own signal.
