I worked as a Chief Engineer at two "graveyard frequency" stations.

The 1 KW limit non-directional is allowed only during daylight (dawn to dusk) hours.

So if you are a "graveyard" frequency fan, you are really listening to some low powered, non-directional AM stations at night.

Re: Inductance Meter(s) to measure 7.5 Longwave Loopstick Inductance - Where to get?

Steve McDonald
 

Steve, after a detailed look I'm not so sure that the DM 4070 will measure down to 2000 uh? The posted ranges for inductance are: 200 uh, 2 mh, 20 mh, 200 mh, 2h, and 20h. Do you know if the DM 4070 will in fact measure down to 2000 uh which is the range we need to measure the Inductance of 122 turns of Litz wire on a 7.5 inch Ferrite Rod?

no problem Jerry....2000uH = 2.0mH so you could easily measure this on the second or third range (2mH or 20mH)

Re: Not Beach Loggings, But...

Hi Michael,

Thanks for your question. In the American AM frequency allocation
system the "Graveyard" frequencies are 1230, 1240, 1340, 1400, 1450 and
1490 kHz. Stations on these frequencies are supposedly limited to 1 kW
power, and there are so many of them broadcasting on the same
frequencies that they typically mix with each other in a ghostly kind
of way every night here in North America.

Although it isn't my particular cup of tea, some DXers specialize on
listening to these Graveyard frequencies for hours on end, hoping that
a new logging will raise up out of the mush. Graveyard frequency
loggings from the USA tend to be particularly challenging for TA-DXers
in the UK and other parts of Europe, making them a prime DXing target
when conditions are good. If you check the peak season TA loggings of
UK DXers listed in Medium Wave Circle's MWN you will usually find
several USA Graveyard loggings, complete with the enthusiastic comments
of the DXers who have logged them.

To my knowledge nobody has accomplished this using an Ultralight radio
in Europe, although Allen Willie in Newfoundland has received a few
very distant Graveyarders using barefoot ULR's at his ideal location on
the Atlantic coast.

update

Paul V Birke PEng <nonlinear@...>
 

Dear Michael

have received the US Plastics container, a little big-I will keep this one the side for now

purchased two yellow 10 quart pails (US quart) with flat bottoms and slight angle

just contact glued  the two pails together after roughing up both surfaces

have received my second order of 100 * 20 * 3 mm bars from Lithuiania

have purchased double sided tape

the bars will be on a nice ~10 degree slop on each side

will use the Polodoroff winding method with Litz I have here so split contra winding as I originally proposed after finding this good patent

need to decide whether to start the bars right at the lip on the outer edges of the form or further  to close the large air gap between the two ferrite sleeve disposition of the bars


the rf magnetic flux lines may pop out a bit but this would be nice mechanically

I will decide that shortly

need to buy some small bubble bubble wrap to obtain teh ~ 5mm before winding

the Polydoroff winding will be resonated with a closed in variable cap  a fancy Yaesu tuning cap with multiple sections that will be connected in parallel

ends of the contral winding grounded and connected to ground side of variable cap
middle connection to the internal vanes of the variable cap


the pickup with be two turns each side of the centre joining area, again a contra winding

I may or may not use a special Dallas Lankford/Chris Trask   JFET follower -P and N channel

also will try with simply my Kaito 1103 placed inside the volume of the open pail

I think the double pail idea is good as is cheap and provides and sloped surface to grab a few more flux lines at the extremes


hoping at least all this makes sense to you

Hello Kirk,

Congratulations on your two new loggings of 1340-KRHC and 1340-KDTD
this morning on the SRF-T615! It's always amazing to hear what that tiny radio can pull in on the Graveyard frequencies-- just look what
Rob has done with it in Ontario. That Japanese-market model is an
Undertaker's dream!

The Graveyards are pretty dead here on the West Coast, though, and not
even the SRF-T615 can dig up many new loggings. Weaker signals get
buried under the morbid chatter of the West Coast locals, and Sunset
Skip dies out early with only the ocean to the west. TP-DXing provides
a quick resurrection of hobby excitement, though.

Hi Gang,

Gary, I really enjoyed the posting about MW DXing from the North
American ocean beaches! That's just a pipe-dream for us landlocked
DXers of Oklahoma. Of course I don't have any TA or TP loggings to
report this morning, but I did luck into TWO new stations in less than
an hour this morning after work, both on the productive frequency of
1340 khz!

1340, KRHC, Burnet, Texas, 1101 UTC, 7/1/11, tuned in to one of the
Texas News Newtworks w/ nx headlines. Hrd a quick call letter ID and
some talk, but soon lost to the station below. I called the station,
and they confirmed I was hearing them. ULR Sta #764.

1340, KDTD, Kansas City, KS, 1111 UTC, 7/1/11, Suddenly covered KRHC w/
back to back ranchera mx. All SS pgm'g w/ call ltr ID and "La Gran D"
slogans hrd (which sounds just like "La Grande" of course.) Been trying
for this one for around a year now. ULR Sta #765.

Wow, this was a nice surprise this morning for sure. My 4 day weekend
has certainly started on a positive note! Logged these stations on my
Sony T-615 rcvr w/ a SAT antenna. Incidentally, these stations were the
17th and 18th stations hrd on 1340 khz! I believe that's my most
productive freq out of them all.

Wishing good DX to all and 73!

A Midsummer AM-DXing Dream

Gary DeBock
 

Hello All,

If you are looking for Good Vibrations while DXing in the middle of
summer, why not consider becoming one of the Beach Boys? (the ocean
beach boys, that is). Wouldn't It Be Nice to forget about summer
static, and enjoy the Fun, Fun, Fun of long-range DX again?

Because of an AM-band propagation quirk in the middle of summer, North
American DXers who head for the ocean beaches during sunrise (on the
West Coast) or sunset (on the East Coast) have unusually good chances
of logging Trans-Equatorial DX from very long distances. Despite the
fact that the Northern Hemisphere is generally in the middle of its AM
propagation doldrums, the Southern Hemisphere is now in its peak winter
season-- and DXers on ocean coasts can tap into a great propagation
pipeline if they know where and when to listen.

DXers on the West Coast should head for the ocean beach well prior to
sunrise, and be completely set up prior to any trace of daylight (in
Washington or Oregon during July, this means being ready for action at
0430 local time). Bring your Ultralight radio with 1 kHz DSP
selectivity (PL-310, PL-380, PL-606 or D96L), or else bring a Murata
CFJ455K5 filter-modified E100 or SWP. Your odds of success will be
further enhanced if you can also bring any type of gain antenna (simple
air-core tuned passive loop, Quantum Loop or other modest gain
antenna), and/ or set up your listening station on a cliff-side
location with the beach directly below. Don't worry about needing huge
gain antennas-- the ocean beach propagation will usually provide more
than enough gain for simple Ultralight radios with modest loops to
receive strong signals from Australia, New Zealand and Tahiti.

What can you hope to receive during one of these mid-summer,
half-asleep beach runs? Well, on the West Coast you may feel like you
are in a dream as booming signals from the South Pacific show up on
your Ultralight radio for over an hour. You may have great signals from
the Pacific Islands (Tahiti, Fiji, Tonga), New Zealand, Australia or
any combination of these areas. Signal strengths can be astonishing--
last year in Lincoln City (OR) my modified PL-380 and 3' loop received
a startling combination of 738-Tahiti and 738-2NR (Grafton, Australia)
that maxed out my PL-380's S/N readout at 25
(http://www.mediafire.com/?eea954j14dmzalm ). Obscure 2.5 kw or 5 kw
stations from New Zealand or Australia may show up, or you may receive
a rare Pacific Island station. Or you may come away with practically
nothing, if propagation is poor-- it's all part of the challenge. Your
odds of great South Pacific DXing success increase if you can schedule
a beach trip for a few days, instead of trying your luck on just one
(early) morning.

Unlike Asiatic TP-DXing, you had better be extremely close to the salt
water (within about 500 feet) to have much chance of success, since for
some unknown reason the DU signals drop out very quickly over land
paths. Mark Connelly has enjoyed the East Coast version of
Trans-Equatorial DXing during summer sunsets on East Coast beaches
(with superior gain antennas), and has noticed the same salt water
beach effect. You need to be near the surf for the best odds. In
general, a few days of exciting T/E DXing will give you a head start on
the upcoming DX season, and may well provide your biggest DXing thrills
for the entire year!

73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)

Thanks to various members of the Ultralightdx group for responding to my post about SDR software for the new Alinco DX-R8T communications receiver. I am pleased to share that we have received several positive responses to the post. As a result, Carl Moreschi, N4PY, has indicated that he is willing to implement support for the DX-R8T in his popular Pegasus Plus SDR control software.

Stay tuned for more details and thanks to all who responded.

Hi Mark, thanks for the reply.

No, I'm not sure at all! :-)

It was a clear KLIF ID, so if KKLF is simulcasting, that is probably what I was hearing.

That sure makes more sense than hearing the 3rd harmonic of KLIF!

Thanks for the information!

Now to see if I can catch their KKLF ID!

Since the Alinco DX-R8T/E receiver has been discussed previously on the ultralightdx Yahoo group, I thought that the following might be of interest to the group.

********************************************************************************

Alinco offers third party Software Defined Radio (SDR) software for their new communications receiver, the DX-R8T/E. This software is called KG-SDR. It looks nice and is free, but it is also somewhat limited. There are other SDR applications out there that are more full featured, but few, if any, currently support the DX-R8T/E. This is in part, because the rig is quite new and also, in part, because Alinco isn't one of the "big three" thus making its addition to SDR software far from automatic.

Still, there are indications that the Alinco DX-R8T will be a popular receiver for hams and SWLers alike. Therefore, I've asked Carl Moreschi, N4PY, if he would be willing to implement support for the DX-R8T in his popular N4PY SDR control software. (See: www.n4py.com)

Happily, Carl has indicated that if someone besides me is interested in DX-R8T/E SDR support in his N4PY SDR control software, he will program support into his application. If this is something that you feel would be worthwhile to you, please respond to this post. I will relay this on to Carl.

A couple of cavaets:

1. I have no connection what-so-ever with Carl Moreschi or the N4PY SDR control software other than as an interested DX-R8T owner who would like his SDR software to support the radio.

2. Although I generally avoid doing so, to get the word out in this case, I am going to cross post this thread in a couple of other Yahoo related groups. Please excuse this if you come across the same posting elsewhere. i can assure you that I don't make a habit of doing this.

3. You are not making a commitment to buy. This is only to gauge if the interest is strong enough for Carl to invest one to two weeks work to add the DX-R8 to his software.
