Many have been good signals but have been unable to work more than a few strong stations because of noise pick-up on the transmit antenna. With a good antenna, you will not need a great amount of power, so it is best not to spend too much time n the Tx (except to make it 'bomb- proof' so it does not fail when presented with an odd load impedance). The time saved can then be spent on constructing a loop antenna that can be located away from the operating position. This can be used to null out any unexpected local QRM. Remember to de-tune the Tx antenna (eg disconnect the earth) when using the Rx antenna. An alternative receive antenna is the EWE. Looking forward to adding LX to my log. 73 de Mike, G3XDV ===============
