kNBR in tampa would be impossible for 2 reasons, 1) the spanish station in St Pete, 2) WPTF in Raleigh is directional to the south.
Also, Way too much spanish interference to ever dream of getting KFI in addition to WVLG in the villages even though their sinal is weak at night.
From where I am in North Tampa, the weak Spanish station from St. Pete goes away when I turn the radio to just the right position, aiming it in a northwest/southeast direction. That would almost put the station from Raleigh at the most unfavorable position for reception too, allowing for more to be heard coming from the northwest of where I am.
The same goes with the Spanish station on 640 which I can greatly reduce by facing the radio west northwest. The music station in the villages will come and go but it's easy to identify because of their music format. During the times when both the Spanish station and WVLG are at their weak cycles is still the opportunity to hear something else that could come in on the frequency.
This is the reason I DX with a directional AM receiver such as the Walkman, rather than one that takes in signals from all directions at once.
