otoh - keeping LORAN working properly with precip static is not
easy...

The LORAN receivers that many of us have in our GA planes are based on
15-20 year old technology. Newer LORAN receivers utilize magnetic
field antennas and advanced DSP processing to greatly improve
reception and immunity to airborne static issues.

In my opinion, the leader in the LORAN industry is LOCUS in Madison
Wisconsin. Take a look at their website, they have many interesting
whitepapers on LORAN as a backup/compliment to GPS.
