When my QRP cq calls don't get any acknowledgement, I just take a look on the Reverse Beacon Network and almost always find that some of the automatic receivers connected to that have indeed heard my rather feeble outputs. When I say feeble - I am not talking about my QRP-Labs kits, but mostly about my rather poor antennas. My main QTH? in a district which is a conservation area and I have to try to operate with low level, invisible antennas, made out of thin wire - usually about 28 or 26 swg. It is surprising how well these can work. My next project will be an end fed half wave with a 49:1 transformer. I think I can throw a 30 meter end fed over the roof and operate it on 40 and 20 meters. We will see how it does next week.
