I see that the Sangean Cl-100 has the ability to block specific types of alerts that may not be relevant to your specific area. Unfortunately, the Cl-100 has to be plugged in all the time or you will go through batteries like candy.
1) For the Cl-100, if you go through the trouble to block some alert types, then remove the batteries and power, do all your settings get lost, or are they saved? This radio may still be on my list of possibilities if this is possible. If I have to redo all my settings every time I get the radio out for camping, that will be a pain.
2) I really like the portable radio as well, (DT-800). Unfortunately, for that radio, I don't think it is possible to block certain types of alerts. All you can do is turn the alerts off. If we are camping, I would want wildfire alerts active, but not some other types of alerts. Is there a portable weather radio out there that does allow selective alert blocking?
