Either every day or every week, I hear radio tests on SPEN 1 and 2. Now, the signal on SPEN 1 comes in very clear, is in CSQ mode, and has no DTMF ANI (or any ANI at all) at the end of each transmission. I hear it simlucasted on SPEN 2. That simlucast comes in very weak, has a 131.8 Hz PL tone, and uses DTMF ANI at the end of each transmission. Now, why are these radio checks on SPEN 1 done in CSQ mode and why are they simlucasted on SPEN 2 (or it may just be the other way around)?
