OK. I cleaned out my mini barn on the back part of my property. It now
looks like what I wanted when I had it build. I've got two shelves up
and I'm going to add six more throughout the area.
It is now primed and ready for me to bring some of my equipment out
there. I brought out the lasy susan table and my GE P780 and later
today I'm going to bring the DX398 out there. I have my Pop Comm / MT
mags - my killer rocking chair :-) - I've been having fun.
Even though I live in a pretty good area whereas there isn't much RFI
to deal with, I did notice a big difference just being roughly 70 ft.
away from the house.
OK - here is the question. With the GE and even the 398 I suppose. I
ran a length of 12 gauge to my AD DX Sloper with a alligator clip and
ran it back to the GE. My thinking was that I could couple that to
both of my radios that way, which I did with the GE already- along
with having my loop out there. Will this work? I noticed a big
difference out there, but I was only out there for maybe 45 minutes
and it was around 5pm - so I don't know if the radio came alive just
because I was away from everything or because I hooked up to the
antenna. Any comments would be appreciated.
Antenna overload will be your enemy. Figure a way to couple the energy
to the receivers without swamping the front-ends.
Gregg. I have to go with Dave on this. the 398 has a lose front-end, and
almost any bit of wire over 20 ft. will give you trouble. i would
say the less hash is your big winner. that sloper is a real keeper, but
I would try your set-up on a few desk tops. I believe you will see a
bigger difference, from the house out there. it's like going from a
random long wire, to a good loop. you really don't receive more, you
just "hear" more. a lot of those low signals have always been there,
but now they kind of jump out at you. sounds like a cool set up. is
your barn dry? if you keep your receivers there, ya gotta watch the
humidity. and don't forget the winter cold, ya don't want to kill
a good receiver. have fun.

I have used my DX-398 (Radiolabs mods) with my Alpha Delta DX-ULTRA
and a 60-foot wire outside, with lots of MW blowtorches nearby (like 2
- 50 kW stations within 2 miles on salt flats and another 5 miles away
or so, plus several others not far), and on SW anyway, it is no worse
than any other radio. They all get some level of images below 3.5
MHz, bit nothing serious above. If I got even ten miles away from
this crummy place, most of that would cease too.

The 398, for real signals, leaps ahead dramatically with an external
wire or active antenna. The built-in whip is too weak - because, as I
understand it, Sangean places a resistor either in series with the
darn thing, or across to the ground, either of which is a dumb idea
and both of which are bypassed by the external antenna socket(s) :-/

Bruce
Is that the Sangean ATS909? It has a real front end.

Dave, i believe he has the super 398. I'm not sure what all the mods
are from radiolabs. but, Bruce is not the first person to state this.
i guess they do something on the front end of this port. if it behaves
on the DX-ultra, it's doing great. i have one here in a tight inverted
V , and it works super.
