Somewhere in my audio cassettes is an actual I'd from KORL when they were on 650. I need to find it before it turns to dust! G

Thanks for the nice bandscan from Honolulu! Quite a few call changes and frequency swaps from how I remember it. I too logged KORL here back in the day. 'Wish I were there right now. ms

> Mixing business with pleasure. Playing with the Kia Sedona rental car radio, while waiting for someone to come and meet me resulted in "expected" stations. Was amazed that the only other island AMer heard was from nearby Lihue, Kaui. I remember one time I was in Honolulu and could hear the West Coast stations during Hawaii daytime. Think car radios were better in those days, at least they had external antennas! Could be crappy Sedona AM section of the radio.

> Keep in mind this is not a scientific "bandscan", just what I heard sitting in my car at Ala Moana Park, Honolulu. No sign of KORL, wherever they are. I was trying to hear the calls, a nostalgic listen since it was my only Hawaiian station ever heard from Mainland, from New Jersey in the 60's and later from California in the 70's. Thought they were on some frequency, but did not hear them. The Star Advertiser newspaper did not list radio stations as they once did.

This is because the proximity of the windings pretty much ensures that each will 'see' the other and therefore the resulting patterns will be somewhat skewed and the nulls likely reduced.
