** An aerial is always a good idea for a radio tuner.Describe what AM aerial you have now and what is wrong with your reception and if it is the same with all stations.
Also - how far are you from the transmitters ?

Careful Robby,
Philthy Phil, (a.k.a. Toaster Boi) - the all round crackpot and net-stalker is making an attempt to work out where you live. Any assumption that he is trying to be helpful is a smokescreen. if you don't believe me, then take a look over in aus.hi-fi and see for yourself.
BTW: Most hi-fi tuners have a pretty useless loopstick antenna which is part of the front-end tuning for the AM section. Unless you are a long way from the transmitters you should be getting reasonable AM reception. The orientation of the loopstick antenna will determine it's pick up sensitivity to a particular station. The user manual for your receiver should make mention of this. A length of wire connected to the AM antenna input should improve your reception.

Dank, free agent aint so free any more.. Ctrl K only works if you pay. I guess a few dollars is well worth it.
**What specific problems do you have?
You should know that for decades (since the widespread introduction of FM) most manufacturers have paid little attention to the design of the AM stages in their receivers. Using different antennae is kinda like shifting a deck chair on the Titanic. If AM is important to you, seek out an Audiosound (Australian made) or Allen Wright tuner. Both are capable of exceptional results. If you want to work within a budget and have some technical skills, seek out an Australian made car radio (AWA made many) from the 1960s. These are also capable of exceptional performance. Off to the wreckers and find an FC Holden.

part of the reason (apart from bandwidth) is a diode is used to take the sound off the IF for a sound detector, a diode is a non-linear device and that is were you get the problems like distortion
for better quality AM take a closer look at "am stereo" receiver even if "your" radio station does not boardcast in "am stereo" the mono sound will sound a lot better than a radio receiver made with just a (crappie) diode for the sound detector.
for more on "am stereo" plug it into google and do a bit of reading.
take my word for it I have made a "am stereo" using the Harris system, it will never sound as good as FM (well we know that already) bit it sound heaps better than a standard AM radio. From EA magazine many years ago, I believe Dick Smith had the kit, also Silicon Chip, (or was the Australian electronics magazine before that ETI)

** Diode AM detectors can produce very low distortion.Two tricks are used:
