Re: [IRCA] [HCDX] CBU 690 Vancouver now at 25,000 Watts fulltime

[Nick Hall-Patch <nhp@xxxxxxxx>]

I don't know if the pattern has changed Neil, but Jon Pearkins was 
mentioning that they were moving to some sort of "modulation 
dependent carrier level" scheme.  This seems to mean that the carrier 
level drops as modulation level increases.  At the least, it means 
savings on the power bill, as even with speech you can see a 4dB 
variation in the carrier level.   (Half power is 3dB, so bet they 
collected some green dollars from the government for that modification as well)

I'll wait for a broadcast engineer to chime in, as I don't really 
know the metrics of defining total AM transmitter power, but CBU may 
have similar audio punch to their earlier higher power when 
presumably, the carrier was roaring away full bore even when the 
announcer was snoozing.

best wishes,
Nick
