Ok. You want to know what full QSK is? Full QSK is when you can hear
EVERYTHING that is on your frequency INCLUDING YOURSELF. Speed is NOT a
factor. Speed could be INFINITE and you would still hear EVERYTHING.|
Now the trick is how to accomplish this. To hear everything, you would need a separate receiver and transmitter. The receiver must be connected to it's antenna at ALL times and be able to receive other signals WHILE YOU ARE TRANSMITTING! To avoid overloading your receiver you have three choices:
1. Invent a new kind of receiver.
2. Run very low, QRP, power.
3. Locate the RX and TX antennas some distance apart. (Like 100 miles)!
Keep in mind the choice number 3 requires a means of compensating for delays in the system.
That is FULL QSK. It is FULL DUPLEX.
FULL DUPLEX (as in telephones) IS DESIRABLE WITH ANY MODE OF COMMUNICATIONS, not just CW.
That is the goal to strive for. Ask yourself if you would prefer a home telephone with anything less than this. Yes there are lots, in fact the vast majority, of CW operators who do not use what little QSK ability they have. They claim to be bothered by background noise and at times it bothers me too such as during summertime conditions on 80m. When the going gets rough, I just turn down the RF gain a bit and things quite down nicely. I never induce delay or go SEMI-BKIn as they call it. I'll probably never reach the goal of full duplex but will do my best.
To those that haven't learned the art of conversational CW, there is always hope. Next time you have a qso with another station just try asking him a question without ending the question with BK or a long call exchange. Just end it with a ? and STOP and wait. See what happens. Eventually he will wake up and realize he needs to do something like answer the question!
In our next article we will discuss the qualities of a good QSK rig.
Hope this helps.73
