I am just curious how many miles you can listen to KHXD 93.1 on a car radio from the transmitter? :-\

10 WATT RADIO STATIONS

I am assuming you are asking about KHDX, the Hendrix College station in Conway instead of KHXD.
Anyway, I havn't listened to that station in a while, but it had OK coverage in the city, but once you got just beyond the city limits, the signal was starting to kick in and out. To say the least, it is very limited.
I usually tune into KHDX when driving into Conway. The range depends upon tropo enhancement which works against KHDX as KZLE 93.1 Batesville is heard in southern Conway (exit 129 on I-40). Sometimes I've heard KHDX north of Conway but usually just to the top of the hill on US65 then KZLE "takes over". Pretty much from exit 127 (US 64--Oak St) to a mile north of exit 125 (US 65/Skyline Dr) on 40 is the "commute range" of KHDX.
The actual KHDX transmitter power is eight watts with the antenna at 18 meters HAAT. A construction permit is for a taller antenna height (28 meters) but a power reduction to five watts.

How did KHDX come to be? And why only 10 watts? I realize that prior to the mid-1980s, schools were granted 10 watt Class D FM licenses. But wasn't this only on non-commercial frequencies? If anyone has the history on how KHDX ended up with 10 watts on 93.1, I'd love to hear it!
BTW, at my location in West Conway, 93.1 is a mix of KHDX and KZLE. Neither station can be received clearly. I'm about a mile SW of the new 124 exit off of I-40.

Don't have a great deal of information on this, but when I was a student at UCA in the mid-70's, KHDX was located down around 91.9 or so...can't remember exactly. I suspect they were forced to move when stations like KUCA received power increases in the early to mid 1980's.
I suspect part of the reason for staying at 10 watts is a lack of commitment from the school to seek a power increase. Just my opinion.
I would guess the reason they've stayed at 10 watts is because a class D license has never been automatically eligible for an upgrade. If a class D wants to become a full-power station, the frequency becomes subject to auction or comparative hearing if in the non-comm band or pre-1996. Class D stations also don't have the same spacing requirements that full-power, and even the new low power FM's, have to follow. Given that there's a 92.7 and a 93.3 not too far away, I highly doubt there'd be any way 93.1 could be licensed today.
By the way, I remember a case a few years ago in New England where a college or high school station in the non-comm band wanted to upgrade from a class D to a full-power signal and lost the comparative hearing to a religious broadcaster. So, they were left with no license whatsoever after spending a lot of money on technical studies to prove their signal could be allocated as a full-power stick. Hendrix may or may not have a huge commitment to the station. You'd know that better than I would, but I'm sure they don't want a repeat of the New England fiasco!

Good points....

Class D stations are indeed only non-commercial. Initially they were all indeed in reserved spectrum below 92. Around 1980-ish, they stopped issuing new ones & expected the existing ones to move to the commercial band. (or upgrade to 100 watts or more, becoming Class A)
