Looks like KVNS will be a rather difficult challenge for me to hear as a sports formatted station, considering I'm less than 16 miles north of local co-channel ESPN affiliate XEPE. I have
heard KVNS as a not-so-oldies station previously one time when XEPE was off a year ago due to a local blackout, but had forgotten until
crainbebo recently reminded me of that fact.
BTW I personally consider music from artists like Dean Martin, Bobby Vinton, Leslie Gore, Beach Boys, Elvis Presley (his younger days), etc. - mostly 50s & 60s - to be "oldies", not 70s and newer, even though I wasn't even born till 1981. Guess that makes me young enough to be a grandson (maybe even great-grandson, although maybe I'm already taking it too far considering both my biological grandparents have passed away and otherwise would be in their 90s) to many of you veteran DXers?

So is there another source for oldies music (60s and earlier) on AM that's regularly receivable (preferably on top of its channel) in the San Diego area? I've occasionally heard a few things on some graveyard channels from the east (like Arizona I suspect), but you know how easy those channels are for hearing music.

As for CFZM, KCBS is often tougher to get around than XEPE. (KCBS's skywave strength here at night may often be comparable to that of, for example, the groundwave of
WSCR, WGN & WBBM in Milwaukee, CFZM in Buffalo, WBAP in Waco, or KOA in Colorado Springs. I haven't tried it with my cheap Coby pocket radios I have, but I wouldn't be surprised if it'd sometimes be strong enough to completely push aside splatter from local 2nd-adjacent 50kW 760 KFMB from less than 8 miles away.)
