Congrats indeed!!

Seconding Rick's comment below -- AM towers make REAL lousy RX antennas. They catch ALL* the front-end-pulverizing noise on 160/80.

"Been there, done that..." well, OK, not the dxpedition part. But I have occasionally at night "borrowed" a few AM "Daytime-Only" auth'd stations' towers for the Ham Jones. Great fun QRP!!!! ;)

* that is, all the noise in their pattern, which admittedly might be more narrow in some elevation angles than the average amateur Inverted-L....

Congratulations on your adventure.

In the past, I have seen some of these AM tower efforts
ruined by lousy receive conditions.  I suggest you
get an advance team out to the site to check
out the noise level etc. and maybe put up some
temporary beverages, loops, whatever and LISTEN
on them.  Use WWV and WWVH on 2.5 MHz as a beacon.

Others can comment on whether 240 feet is too high.
