I've seen (and have one from Midland) field strength meters that include a headphone jack for monitoring of AM signals (and for hum/noise on CW carrier). They are only a short whip, germanium diode, and a bypass cap across meter and phones. A pot is used to adjust the sensitivity, or just pull or push the whip in/out. Works great...
