OK, I'll admit it.
I don't know what people are talking about when they say the E1 doesn't have
an AM antenna.
Doesn't it have a whip antenna.
What more could you want?
What the heck is a "ferrite rod antenna" anyway?
And what does it do differently than the whip?
Thanks all.

Yes.

An internal "ferrite rod" antenna inside.

It's a closed loop type antenna utilizing a high permeance core (the
ferrite) in order to take up less space.

And what does it do differently than the whip?

1. More convenient to use as you don't have to have the long whip
sticking out when you carry it around.

2. The whip is omnidirectional and the loop ferrite rod antenna has two
nulls in the pattern that you could use to null out a competing station
of local noise source, which could improve your reception.

3. The ferrite loop is less susceptible to pick up local noise sources
being sensitive to the magnetic field component whereas the whip is
sensitive to the electric field.

No problem Lenny.

#2 Should have been "competing station or local noise source."

The lack of a ferrite antenna in the E1 is a deal-breaker for me.
Monitoring Times reported that the dot matrix display generated too
much noise and made the implementation of a ferrite antenna
impractical. I'm hoping a future revision of the receiver might
include a ferrite rod.

There should be some way of wiring up a ferrite core antenna in an
exterior box. The thing could be rotated easily and kept a few feet away
from the display. A bit of wiring to the external antenna connection and
you've got everything.

The radio has an external antenna jack that you could use to connect a
small amplified loop antenna. Located a few feet away from the E1 so it
does not pick up the display noise you could point the loop by hand and
I would like that better than having to turn the radio itself in a
certain direction to null out a competing on-channel station or local
noise source. It's more more money and trouble though.

Hi Lenny:
Here are pictures of the insides of a Tecsun PL-200 radio. It's hosted on radiointel.com, a fun & useful site. In some of the pictures you will see tightly coiled copper wire around a bar (that's the ferrite). It's at the top of the radio, and would be on the left side if you're looking at the front.

So, how exactly do you use the nulls?
Does the ferrite rod move around inside the radio with a control?

Great pix, thanks Weatherall.
Does the Ferrite Rod only aid in AM broadcast reception, or does it also aid
SW reception?
