Hallo

TS 2000 users known very well how irritating is internal bird on 436.798 MHz. It is makes impossible(*) to operate AO27 at AOS, has to wait close to LOS or forced to use preamp that is questionable in urban area. I tried today to make QSO on AO27 just after AOS. I was listening in AM mode arround internal bird and did QSO with OE6MDF.A few seconds after AO27 was off (packet).

* - try listening in amplitude modulation arround internal bird :)
