I have an Icom pcr100 fed through a switch by three different antennas - a discone and two long wires each pointed in different directions. Reception seems to be of the same poor quality no matter which atenna I switch to. Local AM and FM stations sound garbled and shortwave is a tough catch no matter where I tune. I know there are lots of factors affecting the shortwave reception but, again, if I do catch something, shortwave reception sounds the same off of all three antennas. I connected long wire directly to the pcr100 and FM reception is fine, AM is okay and I get more shortwave than with any of the three outdoor antennas and this wire is just running across the floor of my basement not really even stretched out very much. I've checked the integrity of the switch and the wire between the switch and the pcr100 with an ohm meter. Its a good quality switch bought a few years ago from a friend in the "business". Because of lots of rain, I haven't gotten outside to look at the connectors on the three outdoor antennas but the chances of all three being funky are slim. I also use the discone for another scanner without a problem. Any ideas?
