Mike, I would like to point out 2 things - first as others have indicated, a 33 ft. wire will be resonant somewhere near 20 meters - for 40 meters, it should be about twice that long, and if you do not have a tuner, it should be pruned to resonance because the KX1 will not perform well unless the antenna jack has something close to a 50 ohm resistive antenna connected to it.
I did get the impression that you connected one far end of your wire to a grounding rod - that is not what you should do - if you are trying to use a 1/4 wavelength counterpoise wire, the far end should be open, not grounded, and be aware that there will be a high RF voltage at the far end of this wire. Such a counterpoise wire becomes an integral part of the antenna system. If you feel you need anything grounded, ground the shell of the BNC connector on the KX1 with a short large conductor so as to create a low impedance ground path. 73, Don W3FPR > -----Original Message----- > > Please correct if this is wrong, I am trying to use my KX1 but > after reading the group emails, I may be doing this all wrong. > > For frequency 7118, I took a length of bare copper wire 33 feet > long, divided (that is cut it ) it in half, took one half to the > center of the BNC connector on the side of the radio and the > other half directly to the grounding rod attached to the house. > but from reading the emails on the group list it now appears I > need to have a insulated coax and I should not be connected > directly to the radio with the two bare copper wires..... > > Mike > -- No virus found in this outgoing message.
