Re: Predicting MW Intermod/Bleedthrough

Thanks for the sympathetic response.

If one eliminates modern DSP designs though, the age of the receiver isn't necessarily the determining factor. If you look at the list - for instance, my decades-old ATS-606 does not suffer from significant MW interference issues, but the brand-spanking-new Tecsun PL-880 does.
Puyallup, WA Ultralight TP's for 9-1

Gary DeBock
 

Hello All,
 
The new DX season started off with a bang here this morning as 738-Radio Polynesie somehow managed its best-ever audio here in the pedestrian DXing location of Puyallup. Although expectations were low for this first day of September (and the Asians seemed to live up to the low expectations), the signal from Tahiti was almost at ocean cliff strength-- quite a shocker.
 
A check of the band at the 1300 start time revealed only a collection of anemic Asian big guns with intermittent audio on 828, 972 and 1566. Knowing that the "K" index was high I checked for South Pacific propagation, and as usual only 738-Tahiti was showing any sign of life from south of the Equator. Around 1315 Tahiti started going on a romp with its French disco music, reaching an unprecedented level (for this location) around 1318. This might be partially related to the larger 15" FSL antenna being used here this season, but in any case the signal was almost worthy of a "Cliffhanger DXing" session.
 
The Asians never developed much energy here this morning, with only 1566-HLAZ reaching a fair level around 1305. There was a large collection of moderate Chinese carriers on 639, 936, 1017, 1323, 1377 and 1593 this morning but none of these could manage any audio. Overall it was strictly a 738-Tahiti show here this morning, and it will be interesting to know if some other DXers noticed its potent signal.
 
738   Radio Polynesie   Mahina, Tahiti   Strong French disco music at 1318; best signal ever heard here in Puyallup
 
73 and Good DX,

I lived in Kinnelon and Parsippany for a total of about 13 years, and in Glen Rock for about 6 months, so
I know what you're running into. There are just too many high power stations crammed into too small of
a geographic area, and withhigh ground conducivity coupled with marshland just to make things worse.

Some of what you're experiencing is likely externally generated. Mixing spurs can develop with the audio
from multiple stations showing up on a different frequency. No radio is immune to those since they act
like their own separate transmitters.

Overload on channel or on adjacent channels is a problem with portables because while the smaller
radios seem immune, that may be simply because they have too small a ferrite antenna to be
sensitive enough ( which means they aren't really good AM DX receivers in the first place ).

At the time I lived there ( 1969-82 ) the small portables of the day were largely inferior to the current DSP
chip designs, and the larger portables had decent nulling capability which could be used.

Bottom line, this is going to be an ongoing issue with portables.

I'm posting this to a couple of
radio-related groups in order to get a wider audience of
collective wisdom. I live in an area of northern New Jersey
that I've come to refer to as RF Alley because of the
concentration of powerful transmitter towers situated in
wetlands a few miles away. The most annoying result of this
proximity is rampant MW intermod and bleed-through on some,
but not all portable radios which can make for frustrating
bandscanning; especially on the upper end of the
band.
Like
many in these forums I've bought many portables over the
years; held on to many and sold or returned others because
of poor performance otherwise, or sometimes just because of
the MW intermod issue alone. I'm getting tired of
playing Russian Roulette with online purchases, and was
wondering how I might predict this propensity ahead of time
- but in spite of reading numerous online reviews before
purchase I often fail because others' experiences doe
not match mine. Can anyone see a predictive
design/architecture pattern here?

Would be fun to build... won't be perfect.... but...


I still have my first Japanese 9 transistor radio I had as a kid.... heard many a Beatle song with it. Unfortunately it got corroded over the years.... dial doesn't work anymore... a good candidate for a rebuild...

So this 2P3 may do for a stand in....

Good point!  So long as there are no SMD parts - my eyes are not good enough to work with SMD any more.  It looks to be a "proper" radio with alignable coils, discrete transistors, capacitor tuning and all.  The audio section looks as if it might be a chip, however.  Still, at the price, it could be worth a trial.

Cape Perpetua Ocean Cliff DXpedition-- Top Ten Signals from the South Pacific

Gary DeBock
 

Hello All,
 
Form August 24-26 another wild and wacky ocean cliff DXpedition was conducted from the Highway 101 turnoff on Cape Perpetua-- Oregon's highest ocean side cliff (2 miles south of Yachats). As expected, the weather was dicey, with gale-force winds making things interesting on the first and last days. This provided some training in surviving such harsh weather during future FSL-antenna-based DXpeditions on such highly exposed venues in the future.
 
To survive the harsh winds the 30 pound, 15" FSL antenna (and its 5' PVC base) were secured with three 175-lb. test plastic tie wraps strapped to the guard rail fence posts on the Highway 101 turnoff (photo posted at http://www.mediafire.com/view/a5rb2ul7s51id3a/Cape-Perpetua-Typhoon-Tie-Down.jpg ). Although this "Typhoon Tie Down" secured the antenna quite well, at one point the clipboard-mounted log took a 20 foot test flight past the guard rail into the green vegetation beyond.
 
In general the South Pacific DX was interesting during the three day trip, but extremely strong signals were rare compared to the 7-day "Rockwork 4" trip last month. Unlike Rockwork 4 the Cape Perpetua cliff has no special preference for New Zealand signals, and the Kiwi big guns on 567, 657 and 702 took major dives. One of the special Kiwi stars last month (702-Radio Live) was completely Dead at Cape Perpetua. On the other hand some Australian signals were noticeably improved, such as 792-4RN. Excellent Australian propagation on the last day also provided some wild DU mixes on some frequencies, such as 567, 639 and 891. A ten-minute fight between 5CK and 2HC on 639 kHz was especially memorable. Overall the ocean cliff DXpedition was another thrilling experience (in more ways than one). All the loggings below were made with a 7.5" loopstick Tecsun PL-380 Ultralight radio inductively coupled to a 15" FSL antenna. DU signals which pegged the PL-380's S/N display at the 25 maximum are identified with a double asterisk (**). 
 
**531  PI   Auckland, New Zealand  (5 kW)   Once again this Samoan-language Kiwi station set the pace as the strongest DU signal during
                   the DXpedition, with potent signals every morning. It occasionally had some competition from the 10 kW NHK1 station JOQG but 
                   had no trouble dispatching the Japanese after 1300 UTC
 
594  NZ's Rhema   Timaru/ Wanganui, New Zealand  (5 kW/ 2 kW)   Oddly enough this low-powered Kiwi network ruled over the Aussie big
                   gun 3WV on all three days. Here it is with typical Christian contemporary music at a good level // 684 on 8-25
 
603  Radio Waatea   Auckland, New Zealand  (5 kW)   The strongest of the Kiwi Maori language stations during this trip, although it wasn't quite
                   up to its typical Rockwork strength. It usually dispatched the Korean big gun HLSA around 1300 UTC daily
 
**639  5CK   Port Pirie, Australia  (10 kW)   The biggest surprise of the DXpedition, and a new logging. Not in the Grayland master log (but
                   heard by Nigel in Alberta), this ABC LR network station was noted at a potent level on 8-26, parallel to 891-5AN (which, according to
                   Paul Philbrook of South Australia, rules out the 1 kW LR network station in Mossman, which has a 30 minute time difference in LR
                   network programming). This ABC station was fighting it out with the Aussie commercial co-channel 2HC for a full 10 minute
                   period on 8-26-- one of the longest-running Aussie snarls I've ever heard
 
639  2HC   Coffs Harbour, Australia  (5 kW)   Commercial co-channel of 5CK occasionally had the upper hand during a wild snarl on 8-26 
                   but generally lost out to the South Australian ABC station. This MP3 has a mention of "Coffs Harbour" after a commercial at the :58
                   point (thanks very much to Sam Dellit of the ADXC and Ultralight radio group for deciphering this).
                   Full ten minute snarl of the 639 Australians 5CK and 2HC from 1335-1345 on 8-26, the last morning of the DXpedition (7 MB
 
**675  RNZ   Christchurch, New Zealand  (10  kW)   One of the rare Kiwi stations with better signals than during last month's Rockwork 4
                   trip, this was by far the strongest RNZ network performer during the DXpedition
 
684  NZ's Rhema   Gisborne, New Zealand  (5 kW)   Another Kiwi station with improved signals during this trip, with Christian contemporary
                   music at a good level // 594 at 1350 on 8-25. A rather anemic Rhema network ID is at the end of the recording    
 
**738  Radio Polynesie   Mahina, Tahiti  (20 kW)   Typical French disco music at a potent level at 1124 on 8-25, it usually had some KCBS
                   splatter to deal with (the San Francisco pest is a daytimer at Cape Perpetua, OR)
 
**792  4RN   Brisbane, Australia  (25 kW)   One of the strongest Aussie stations during the DXpedition, this RN network big gun was far more
                   potent than its 576 parallel. No sign of the Kiwi Radio Sport at all-- the opposite of the Rockwork 4 situation last month.

well, since this is a kit, you will probably be able to fix it.

Looks like a longer than usual ferrite rod on the antenna coil.
If this had a tuned(or even untuned) RF stage, this might perform quite well.

Hello Paul,
 
<<<   I would agree with others that the ABC station on 639 would most likely be 5CK at Port Pirie 10Kw, only about 200Km north of Adelaide and 5AN 891.
If it is the same programming as 5AN then it would be in South Australia or Northern Territory.
In the evening ABC run National programming but the SA/NT broadcast is delayed half an hour to compensate for the time zone so you will not hear parallel programming from the eastern states.    >>>
 
Well, that pretty much confirms the 639 ABC LR network logging as 5CK in Port Pirie, SA, Paul. All the other experts (including Sam Dellit) had said that 5CK was the probable identity (since the 1 kW transmitter in Mossman (Eastern Australia) doesn't seem to get out very well, even in Australia. Your information about the half hour delay in ABC LR network programming between the 891-5AN parallel signal and eastern Australia nails down the identity of my 639 ABC logging as 5CK in Port Pirie.
 
By the way, at 13,075 km (8,125 miles) this 639-5CK logging during the Cape Perpetua DXpedition breaks the current Ultralight radio worldwide 10 kW DX distance record set by Gary Deacon at Seefontein, South Africa on 3-18-2009 for his reception of 1660-WWRU in Elizabeth, NJ, USA at 12,455 km (7,739 miles). Before I get too excited about this, though, I'll need to keep in mind that Tony King of Greytown, NZ (the "Kiwi King" of X-band DX) has probably received other 10 kW DX stations at a farther distance on his PL-380 and tuned loops-- and just hasn't claimed credit for them :-)
 
<<<   I would like to know the path these signals are taking, as they really only have oceans to the south and it is quite a long overland haul to the east.   >>>
 
Me too, Paul. Many times 891-5AN has had a blistering signal on the USA west coast while all the eastern Australian stations were completely inaudible. There are definitely two different propagation paths involved!
 
73 and Thanks,
Gary DeBock (in Puyallup, WA, USA)

None of those cities are in the way on 720 kHz.  You would have to tune to the lower side of 720 kHz to avoid WOR HD New York interference though, but it could be done in the narrow 715 to 720 kHz open space between the 5 kHz limited WOR analog and the WOR HD digital signals.  650 kHz has WSRO Ashland (Boston) and CKGL Newfoundland co-channel in addition to 660 WFAN New York interference, and of course you would have to get by WMCA New York to receive 570 kHz, but 720 should be doable with an ultralight that has selectable bandwidths of 3, 2, and 1 kHz such as the Tecsun PL-380.  October and November have typically been the best for DX from high latitudes.

I have too many radio stations here in NJ lol. I might luck out if I was to get to the shore, either on the coast of NJ or possibly farther south.... possibly picking up a water path.
 
Oh well. Guess a trip to Maine is in order.

From DXpeds in Cappahayden (about 110 km South of St. John's) we heard them all over the years with Beverages. 720 was by far the easiest and in late fall could start skipping in several hours prior to sunset. The others were more difficult, and there was also one on 900. Best times for the others were typically near sunrise. Note that three of these are on TA channels and that by sunrise the TA's should have faded.

Quite a few DXers on Cape Cod got 720 a couple years ago. Note that CHTN had gone to FM and that they don't have serious QRM on 720 around sunset. Whether anyone tried for them with a ULR, I don't know, but suspect when it was in well, they could probably get it barefoot.

I'm quite sure that Sylvain Naud who lives north of Quebec City has them logged with his Bevs.

One of the most interesting catches of my 50 years of DXing was getting them from my WI DX Paradise spot 20 miles north of Milwaukee on a bluff 150 ft above Lake Michigan. The QRN issue, of course is WGN, but I phased two BOGs aimed about 30-35 degrees and was able to knock WGN down enough to have Greenland almost equal to it on peaks for nearly half an hour using my Drake R8B until it faded down. I'd probably had them in the mix previously, as I'd noted stuff that surely didn't sound Spanish (Canary Is. or a Mexican off the back end) nor Portugese a couple of times.

In that directions there's well over 100 miles of open water before any land, and while fresh water isn't as good as salt water for DX, I think there's still about 10 dB enhancement vs having no water.

Re: the other stns from Greenland. I don't know anyone who's logged any of them from the USA in recent history. 720 is in southwest Greenland and is the closest and has a water path. I do know that DXers visiting St. Anthony logged them daytime on a portable.
