Tropos are what got me Hooked on DXing!! I just love working TROPOS out of the Chicago area back in 1968 to 1970. It was the MOST EXCITEMENT I have had in Ham Radio!!!! I nailed 8 states on 2 meter AM, it was great!!! We don't get much in the way of TROPOs out here in Kalifornia, but we do get the wonderful DUCTs to Hawaii!!! I worked a station there on the BIG ISLAND that was louder than any local on 2 Meter SSB.
