Look in the owners manual for a section on receiver tuning. Not sure
about the R21, but newer Raymarines have a digital control of the
tuning right from the display. It sounds like your receiver tuning
has drifted off the transmitter.

My radar screen still reads the echoes, but the screen gradually became full of

from scanning and the squelch cannot filter it out on any channel. As soon as
the radar is "ready," my VHF starts scanning again. My open array antenna
spins, and even with the screen full of snow, I can still read the echoes.
Anyone know what's wrong and is it worth fixing. It a 12 year old Raytheon R21.
