Not quite true,certainly using the TX EQ even having a 2.8Khz filter to TX,you can make the TX bandwith narrower,as narrow as just 2.2Khz not to bother others in a contest enviroment and still sound very clear.

Lu -

One important thing to remember is that, while you're cranked down all
nice and narrow on RECEIVE, you're still transmitting through the 2.7
or 2.8 kHz filters, so your TRANSMITTED bandwidth is quite a bit wider
than your RECEIVING bandwidth...
