After seeing the recent post by Drew about interference from AO-51 on 145.880 coming from a Louisville repeater, as the president of the ham club in Louisville, I forwarded the posting from Drew out to the membership.
Here is some info I received from some members: >I listened to the audio track. The call letters of the interfering signal is >KB4PTJ. >This repeater is located in Shelbyville, KY and operates on 444.050 >TX/449.050RX >with a PL of 91.5, and is associated with its companion repeater located in >Williamsburg, KY (also 444.050/PL >100.0) and linked via the Internet to several repeaters around the eastern US. >I know of one in Virginia and another >in New Jersey. > > >The owner is: Will Jones, a HVAC contractor who lives in the >Williamsburg/Corbin area. >He may well be interested that his repeater audio is interfering with the >AO-51 Satellite. >Will is very knowledgeable and would want to do right by the situation. My guess, is that since this is a 70cm repeater, the chances of it actually emitting on 145mhz are pretty slim. My bet is on a rouge cross-band repeater by someone who picked a 'clear frequency'. I have been monitoring the frequency and it seems quiet. If it comes up again we can organize a foxhunt to locate and educate the owner.
