Hi The bandwidth of anything close to a Loran signal is a *lot* wider than any of the ham bands contemplated below 1 MHz.
There's the minor issue of getting the power company to put in a cable to the house for your 1 Mw (capital M not lower case M) transmitter. Even though it's pule, the RF power is way beyond the sub 1 W outputs currently contemplated on those bands. Signal to noise *does* matter. Bob On Oct 5, 2010, at 12:20 AM, J.
