Default No Replies to my DX398 RCA dilema?

Anyone? I see all these other posts and I help when I can. I'd like to try this
new jack but have the same setup as I did the original external antenna jack.
Can someone tell me what I can put on that RCA as a permanent sleeve like I did
with the other and plug into and out of with?

I'd VERY much appreciate it.

Thanks,
DX

Here is my repost in case it didn't go through, at the bottom I will seperate
it and show you what Justice at RadioLabs said to do, it seems that there HAS
TO be an easier way. {?}
**************************************
That RCA jack on the back, Chris said would be so much better for sw than the
other external antenna jack.

With the original jack, so I didn't loosen the jack or board I went to the
Shack and bought a 'sleeve' so too speak that I could keep plugged into the
ext.antenna jack all the time and it had an end that accepted the end of my
sloper (homebrewed) which is a typical 1/8" plug. So when I listen, I plug into
my sleeve without any pressure whatsoever on the jack itself or the board by
it, when I'm done I unplug. But there is ALWAYS that one end (the sleeve I
knicknamed it) always plugged into the external antenna jack.

I went to the Shack looking for the same thing today (er...yesterday Wed.) and
I got (against my better judgement)a cat#274-387 it says Stereo to Mono Audio
Adapter *accepts 1/8"stereo phone plug/fits phono jack. I plugged the end of
my sloper, th 1/8" adapter into it ( the other end 'slid over' the RCA-not
into-like it should have IMO.

Bottom line: I couldn't hear hardly anything. I unplugged my antenna from it
and heard more from the adapter I just bought slid over the rca then before
with the antenna plugged into it.

Can some nice soul tell me exactly what to get from the Shack, maybe a cat#
would be great. Just looking at the RCA that was installed, it looks like (I've
never had an RCA jack) something physically goes 'into it.' Justice at
RadioLabs said how much better that jack would be, that I'd like to try it out,
but I went back to the tried and true 'sleeve' into the original exter.antenna
jack and everything was fine.

Any help would be GREATLY appreciated.

********************************************
Here is C.Justice reply just on the RCA external antenna jack add on they
install, the rest was snipped.
***********************************************
The antenna jack on the Super 909 mod is very simple. The tip is the signal
input, the shield is the receiver ground. If you are looking for an adapter to
go from the 1/8" stereo plug to an RCA connection, there is probably nothing
commercially available. The best thing to do is go down to the local RS,
purchase a RCA plug and a stereo jack. Wire the plug so that 2 wires go to the
tip and ground on the RCA. Next, wire the "ground" wire to the first connection
on the stereo jack (the barrel).... then wire the tip to the tip connection on
the other plug. This will be a custom adapter to go from your current antenna
connection to the RCA jack on the back of the 909.
************************
Hey group, is this the ONLY way to do what I did with the original external
antenna jack antenna that works 'perfectly'? He said this add-on jack is much
better for shortwave. {?}

I'd appreciate any help from someone.:-)

I'm not sure about your problem. On the 398, when you plug in the short
wave antenna into the 1/8 jack, the ferrite bar (AM) gets shorted out.
This site shows how to use a *stereo* jack to enable both medium wave
*and* short wave antennas on the 1/8 inch jack.

The RCA jack that you had put on the back must be for SW only.

I'm not sure if this helps. Let me know..

If I'm understnading you: Shack has an adapter whihc plugs into an RCA jack and
takes an F connector. To that Shack has an adapter that plugs into the F female
on the above adapter and takes a BNC connector.

Er, if you plug a mono phone plug into a stereo jack, it shorts one
of the contacts (the ring) to ground. (Most stero headphone outputs
need to have resistors in series to prevent this).

Tou're using a mono to stereo adapter, it splits the tip contact on
its plug into a tip and a ring contact in the socket. And then, using
the old plug, you're shorting everything.

Use a stero plug with the ring terminal not connected to anything on
your antenna.

I re read your post. Is it a MALE rca cable end you need? The outer ring
becomes the ground and the inside pin is the signal.

The RCA jack that you had put on the back must be for SW only.

I know Leopard (BTW it's for FM also) but on the 398/909 yahoo group someone
posted a link on th rat shack site, it was what I needed to make it work with
my existing antenna setup.

I don't like it (the adapter) as much as the other for the original antenna
jack, but Justice wasn't embellishing when he said it would be better (that RCA
jack and whatever he added to or bypassed with it) than the original.

I was hearing things on SW during the day, nothing really important or anything
that sticks out/particular freq. I just know that certain parts of the spectrum
were more 'alive' with the RCA jack antenna. I'll now be able to put up a
better bigger antenna without fear of overloading the front end of *having* to
back my gain down ALL THE TIME to hear something either durng the daytime or on
the 60 meter band with the static crashes that it s known for.

The adapter is cat#274-871 Mono-to-Mono Phone-to-phono Shielded Plug
Adapter/accepts1/8" mono mini phone plug/fits rca phono jack:$3.99 Gold Plated
Inline Adapter was the main name on the website.

I wished there was 'chord' with it except just a 'piece/adapter' but I guess I
can live with it, you can't see it anyhow.

As for the BCB I know that it 'says' it shuts off MW, but maybe I have the
right one or it was soldered backwards or whatever, but it works well on MW on
the wire. But that isn't a concern for me because if I use the 398 to DX and
log for qsl, the antenna and all that will be unplugged and sat on the lazy
susan table and I have the choice of two real nice performing loops, that's not
even countin the two rat shack loops I have.

So I have the BCB covered. Something I noticed and really like is that with the
new speaker and all the extra filtering and front end work etc. etc. I leave
the tone/voice set on 'music' now instead of 'news' which I ALWAYS kept it on,
even if I was listening to music on the VOT or some other middle eastern
station.

But the voices sound so much fuller and richer now even when in just talking,
that I'll leave it there. And guys, if you've never had a *Sky Blue* or *Ocean
Blue* LCD you just have too get it or change it over, it is incredible.

Before, I had to lean over to see or at night I had my mini-mag sitting next to
it, but now I can sit at the monitor and just turn my head. It is soooooooo
bright that I've read some people are using it for a nightlight, which I won't,
but that gives you an idea to the difference.

I am spoiled nown compared to the crapola green that most manufacturers are
staus quo with on their LCD's- why in the world wouldn't they put these in
instead-is it that much of a price difference.

As for my modded 398, the jury is still out, but first impressions have been
very nice and I'd recommend it if you have been thinking of going with CJustice
at RadioLabs.

Mark,
You're saying simply a 1/8" stereo plug to use soldering onto the end of my
long wire?

What difference would that make now, in that it's working fine and all?

I'm trying to remember what happened at the shack the day I went up there and
asked them for that, they didn't have it or something-or the guy gave me the
package and I didn't look.

Matter of fact, it had two of em' in the pack and I stapled it closed after I
used the one, this is what's on the end of my long wire now cat#274-288A Two
Conductor 1/8" shielded phone plugs.

That is 'exactly' what it says on the package, so I asked for stereo (the right
one) and nit knowing what it'd look like I trusted the guy I suppose, it's been
a while.

You're saying this is a 'mono' plug? I'll call the shack now and give them the
cat# and ask them or type it in their website, but it doesn't say stereo OR
mono on it. {?]

It has the tip, then just a tad of space then a black circle on it, if that
helps identify it. I'll look at the pic of the one link of the proper one and
compare it to this one I have here.

I found one on their website, but it doesn't have the *A* on the end of it. It
says "1/8 phone plug - 1/8 diameter shielded plug.

That looks like it and it says "comes in package of two"- like mine did.
