[amsat-bb] Repeater interference on AO-92

[nathanjwhite]

A couple of weeks ago we identified 2 stations overheard on AO-92 with apparent Boston area QTH (Waltham and Harvard) but still no indication of a repeater.AMSAT has a recording of the pass.

Cool, it’s challenging because the length of passes aren’t much longer than the interval to ID. It’s frustrating but perseverance pays off.

>> AMSAT can only sort it out with the help from users, they have no magic wand. Through a process of elimination the region the offender is located in can be narrowed down by figuring out a common footprint. Continued monitoring can also reveal a repeater or user ID. This process has been used in the past to track down offenders. Keep listening and forward any call signs you hear, AMSAT will definitely reach out to them. Also, recordings help.
