[Elecraft] Why Not Remove the Birdies Through a Firmware Update

hearing.

Before moving all of the Rx birdies using firmware, IMHO it would be wise to 
take a *comprehensive* look at the transmitter spurs as well, because in a 
TRANSCEIVER if there are Rx birdie problems present chances are that there 
could be some Tx spurs which need to be addressed. Unfortunately and 
obviously Tx spurs cannot simply be moved in frequency using firmware, but 
if a problem must be reduced in amplitude. Often one result of such work on 
a transceiver's Tx spurs is to reduce / eliminate some Rx birdies as well.
