620 and 1030 AM's off the air

S

Signal Geek

620 and 1030 AM in Puerto Nuevo, Mexico (southwest of Tijuana) have been off the air for weeks, if not months. Anyone know why? They share a tower site.
 
Bit of DX info just for fun, when 620 is operating, from our location here in the SFV, you can easily hear the Hanford/Fresno station
underneath all day. At night though it's all KTAR.

Perhaps the stations are transitioning to FM like so many Mexican AMs...

There are not any FM frequencies available along the border. To allow for the transition of about 80% of all Mexican AM stations, the government changed the rules on overlap and second adjacent frequency allocations in the same market, adopting the standard use in all the rest of Latin America.

However, along the border Mexico has to respect the terms of the joint agreement between them and the US so very few border AMs could move.
 
Speaking of 620AM and 1030AM according to radio-locator they are supposed to be directional antenna, but there's only a single antenna site at their location. Is the station transmits directional signal or non-directional signal?

While it is possible to slightly directionalize a single tower by tuning the guy wires or dropping a tuned wire vertically from a guy part way down, the distances and heights involved make anything but slight nudging of the signal possible.
