Without the attenuation removed, it is a pretty dull performer on MW. I
would imagine you have not been able to detect even the easy TPs with it.
I can get the TIS stations at LAX and Barstow.

In other words you can't get any TP´s.


WTF is a TP?

Trans-Pacific reception.

Like San Diego?

I've never tried to get any stations from East Asia nor South America on
the MW. It seems that would be more a function of filters than MDS.

The MW term for Trans Pacific DX from the Western Hemisphere.

TPs are often heard from California, including NZ, Australia, Japan,
Siberia, etc., etc. You need selectivity to pry them out between the
domestic channels and sensitivity as the path is long. The ICOM does not do
it well without the mods.

The reciprocal would be true as well. Same for TA (Trans Atlantic).

But I'll bet you any tube radio from the '50s would have no problem. I
quit seriously DXing AM stations when I started working at them. I was
14 at the time.

Trans Pacifi DX site #1 http://www.qsl.net/n7ecj/

One station mentioned, "1475 MALAYSIA (Borneo) RTVM, Kota Kinabalu SEP 23
1145 - Noted only as a strong het on their normal off-frequency channel.
(Bryant-WA) " was, when I lived in Arizona, the indicator of deep pacific
DX potential. At 600 kw on a non-conventional channel, it came in well quite
frequently and when it was very readable, it meant there might be
opportunities for other TP stuff.

South America is fairly easy from SoCal on MW. The big Colombians below 1100
(Colombia breaks the band into high power (10 kw to 250 kw), medium and low
powers, with the low part of the band all composed of high power stations.
WRTVH has a fairly accurate list of HJs on MW, and I believe (although it is
in Spanish) the regulatory body (Ministerio de Comunicaciones) has a list
online.

Not enough selectivity to separate the 9 kHz channels from the Western
Hemisphere 10 kHz channels. And definitely not sensitive enough.

I could get XEROK at noon in Phoenix in my '56 Cadillac. I got WBZ on a
Zenith All-American 5 tube radio in my filthy bedroom in Scottsdale when
I was 12 or 13.

XELO (XEROK) was a 150 kw station; it had a better signal in some parts of
the Phoenix metro than a couple of the local stations.

I've got an issue of Broadcasting from the later 40's with a WBZ ad showing
mail pull from all the states. Noise levels were so low then, and the band
was amazingly less congested that this sort of reception was normal. And
nothing like the conditions and gear required today to get a TP or a TA.
