Longwave experiments with the PL-380 are going well. Yesterday I tried a variety of coils and parallel capacitors, and settled on a 2650-uH coil and no parallel capacitor. That gave the best results on two beacons that are steady here during the day. This 2650-uH coil tunes up to about 490 uH. BTW, based on dozens of experimental antennas and coils, the total minimum capacitance with an external coil or antenna connected through 2-3 inches of wire seems to be about 30 pF, and may be as high as 40 pF. This matches results obtained by Roy Dyball (where is Roy these days?). It also tells me that 240 uH is the best inductance for a MW antenna or inductor, assuming you want to tune the antenna/inductor across the band. This also matches Roy's results.

It appears that a long ferrite rod with lots of inductance picks up so much more signal, and the higher inductance causes higher voltages to be developed across the coil, even when it isn't resonant, that there is an apparent improvement over the stock antenna, which is pretty poor by any standards. On the low end of the band where the inductance does resonate, the improvement is breathtaking. Assuming you want to DX the full band up to 1700 kHz, it's worth adjusting the inductance to resonate the coil. While the larger coil does outperform the internal antenna, resonating it makes it even better, with only slightly less gain at the low end of the band. It all depends on what part of the band interests you. A really large inductance will tune from about 320-1230 kHz; above 1230 it may still outperform the stock internal antenna or even the stock rod rewound with Litz wire -- but you can do better at the high end if you're willing to give up 320-530 kHz. (A 7.5-inch rod with about 100 turns should do wonders on LW. A 60-turn winding is about right for MW, and you could mount a small switch to add another 40 turns, making the same antenna work on both bands!)

You can tell if the antenna is resonating by holding another portable near the antenna and tuning both radios to the same station. Then change frequencies on the one controlling the antenna and see how the signal strength varies on the second radio. Within a few kHz either way, signal strength should start to drop. If it doesn't change, you know the antenna is not resonating. The advantages of resonating the antenna are, even better signal strengths and better selectivity ahead of the radio, which can help a lot when you have adjacent flamethrowers.

After reworking my LW coil and matching the impedance to my three turn Hoop Loop, I hit LW again last night. Sunset was disappointing, but things started happening about 10:30 pm local time, 0230Z. Lowering the inductance of my coil perked up the high end of the band, to the extent that R Enciclopedia (530 kHz) was very strong. (Even though the coil doesn't resonate at 530. The coil reactance is 8825 ohms, vs 800 ohms for a 240-uH coil. The Stella Maris beacon on 526 kHz was also strong, but I noticed more splatter from Cuba than I get with a MW coil in place, because the larger coil doesn't resonate at 526 kHz, so selectivity is not as good.)

Switching back to LW I started tuning downward in frequency, and in a few minutes logged a new country, with PPA 450 kHz, Puerto Plata, Dominican Republic. http://kearman. com/images/ PPA-450.mp3 

Moving down to the broadcast section of the band (153-279 kHz), Radio Europa-183 in Germany was coming in well.

Algeria-252 was audible just before their sunrise, but not strong enough to log. Checking 531, the Algerian heterodyne against Cuba and RVC was weak, so propagation favored more N-S than E-W paths from here last night.

All of the Europeans come in at similar antenna directions. There is a lot of noise here on LW, and I'm hoping that moving the antenna outside will help. It's late in the season, but maybe a few more LW BC stations will fall into the log. Here's last night's log, times in UTC.

Puyallup, WA TP's for 4-4

Gary DeBock
 

Hello All,
 
After yesterday's unusual propagation to Korea here, this morning seemed equally mediocre to all Asian areas. It's tough to believe that nobody else has posted a TP report on the IRCA list today (I haven't received any here), but for those of you who slept in, you apparently didn't miss much.
 
1566-HLAZ and VOA-1575 had fair audio around 1325, and 1134 kHz had a fair mix of stations shortly thereafter (apparently JOQR and KBS). 1377-CNR1 was pretty anemic during the short listening period, and the 1476 kHz carrier barely registered a weak heterodyne on the modified ICF-2010. 1503-JOUK was down in the noise, rarely producing audio. No trace of any co-channels were observed on 1377 or 1575 kHz, and the low and mid-band "big guns" had a difficult time producing much audio. It was an easy decision to turn off everything around 1330, and wait for a better day :-)

Re: Ferrite rod request

Hi Paul,
 
If you find no other volunteers for this, I do have another shipment of these on order from Amidon (due to arrive next week), and would be happy to reserve one for you.
 
For you or anyone else interested in constructing a Slider coil for their E100, I do have several spare Slider coils (with the latest refinements) available here. These may either be used as a guide to assist in construction, or soldered directly into the E100 and used as a very effective DX antenna (in combination with the 7.5" Amidon type 61 ferrite bar).
 
Congratulations again on 500 stations logged!

An FM Ultralight Surprise

John Cereghin <jcereghin@...>
 

I just bagged a nice log with my Tecsun PL300WT barefoot:

101.5 WCFA-LP, Cape May NJ, 2240, jazz, call ID.  83 watts at 47 miles.  First time heard.

I was able to split this off from the usually dominant WKXW in Trenton NJ.  Some great tropo conditions tonight. 

And it just goes to show what an ultralight can do with FM tropo DXing.

Re: 500 at last

Paul Logan
 

Hi all,

many thanks Jim, Richard, Gary, and Robert, for all of your kind words regarding my latest UL milestone. It's a pleasure being part of this group.

Gary I have prety much exhausted barefoot possibilities at this point ( except for exceptional propagation conditions) - I think next winter I will concentrate on using loops - I'm envious of the monsters that inhabit your back yard btw.

Sadly my own neighbours are very close and already think I'm slightly unhinged so if they saw me tuning a 9 foot loop every dawn they might ask for a professional intervention of some sort!

Robert, I will send you some award applications soon. One will be for an upgrade on my Canadian provinces from 6 to 8 - I managed Alberta and BC last November barefoot - two particularly thrilling receptions of CKMX 1060 and CJVB 1470. Radio doesnt get much better than the sound of exotic signals out of palm sized radios!

regards to all and good dx

Re: PL-380 - tuning knob broke again :( (also a TP question)

Gary DeBock
 

Hi Stephen,
 
Out of twelve PL-380's that have passed through here (for myself and others), two have had tuning controls with binding rotation (requiring disassembly, adjustment and/or lubrication), but none have had the tuning control fail to the point of being unusable. For a rough-tuning PL-380, the usual culprit is a slightly crooked tuning control scraping the cabinet cutout slot, and the usual solution is to disassemble the radio, and physically push the control into a straight position. Occasionally, white lithium grease is useful to restore free rotation to the mechanical parts of a sticky ULR tuning control. Since your tuning control has already broken completely, I would suggest you notify Anon-co that you have received a defective radio, and ask for repair or replacement under the one-year warranty. 
 
  " Also, I have a TP/TA question. I think we all know that salt water is a major conductor of radio signals. I've also heard of people receiving TX AM stations in FL in the daytime, and vice versa, using only their portable radios' stock loopsticks, and have heard of reception of NYC AMs on beaches in SC. Also, from what I've heard, the 9' PVC loop can take a signal on a ULR from completely inaudible to total blocking/desense, massive overload, etc.
Ok... considering all those factors, and the fact that some TPs (and TAs) transmit with MUCH higher power than stations in the USA (several hundred kW to over a MW)... assuming you're using the 9' loop and a good, sensitive radio, not swamped by locals (L.A. DXers need not apply)....
is it possible, if you're on the beach facing the target station, to actually get the GROUNDWAVE signal from low-band (540 to maybe 810 kHz, possibly higher) high-power (250kW+) TP stations across the salt water?
Oh.... I should mention that DXing KNOM and KICY from the eastern tip of Russia/Siberia does NOT count! :D
(And what's Gary DeBock's best TA, TNP (trans-north-pole) or TE (trans-equator) catch so far? "
 
Stephen, DXers on ships can routinely receive high-powered AM stations across ocean paths around local noon at ranges over 1000 miles, during excellent winter conditions. ZNS1-1540 in the Bahamas has apparently been heard on Massachusetts beaches this way, and a New Zealand DXer told me that he could hear some Australian AM stations "across the ditch" around local noon, during great conditions. Of course a superior gain antenna always helps, but even with a 9' loop, it's highly unlikely that any TP will be heard on our west coast at local noon. Speaking of Alaska, I'm sure that the several of the Russians could be heard in the Aleutian Islands, with an outside chance of receiving the northern Japanese big guns (like 774-JOUB and 747-JOIB).
 
As far as my best TA catch so far on the 9' loop, all of the six TA's I've heard so far would be considered "big guns" on the east coast, and nothing special. Judging only by the number of mp3 listening "hits" on my Mediafire account :-) , the most popular would be 693-BBC and 756-DLF. The best T/E catch would probably be 1296-1ZH, a 2.5 kw Hamilton, New Zealand station heard on the 36" portable PVC Loop at Grayland, WA last August.

I've already ruled out several, like the PL-310, PL-360, PL-300WT, DT-400W, SRF-M37W, ICF-2010, etc, for various reasons, including not-as-good selectivity, no multiple bandwidths, severe soft mute, among other things. I really would prefer not to buy another radio at this time, though, but there are some issues that really need to be corrected, including the flimsy tuning knob, having some "blank" frequencies with a 45-50dBu noise floor when I'm not within 1/10 mile of a 50kW IBOC blowtorch (instead of the 15dBu typical in rural areas / faraday cages), still too much soft mute / audio pumping on fringe/borderline signals (especially annoying when listening to a station that has co-channel interference when the two stations' carrier frequencies aren't exactly synchronized), among other things.
> I really want to like this PL-380, though... the selectivity is, to put it mildly, amazing, except when faced with extremely strong signals. Even so, compared to my previous radio, a Panasonic RQ-SW20... well, it's NO comparison. (The RQ-SW20 is about as wide as the Sony SRF-M37W.) It's just that some stations that should be clearly listenable on this radio are pushed below the raised noise floor due to strong locals > 150-200 kHz away.

I've already ruled out several, like the PL-310, PL-360, PL-300WT, DT-400W, SRF-M37W, ICF-2010, etc, for various reasons, including not-as-good selectivity, no multiple bandwidths, severe soft mute, among other things. I really would prefer not to buy another radio at this time, though, but there are some issues that really need to be corrected, including the flimsy tuning knob, having some "blank" frequencies with a 45-50dBu noise floor when I'm not within 1/10 mile of a 50kW IBOC blowtorch (instead of the 15dBu typical in rural areas / faraday cages), still too much soft mute / audio pumping on fringe/borderline signals (especially annoying when listening to a station that has co-channel interference when the two stations' carrier frequencies aren't exactly synchronized), among other things.
I really want to like this PL-380, though... the selectivity is, to put it mildly, amazing, except when faced with extremely strong signals. Even so, compared to my previous radio, a Panasonic RQ-SW20... well, it's NO comparison. (The RQ-SW20 is about as wide as the Sony SRF-M37W.) It's just that some stations that should be clearly listenable on this radio are pushed below the raised noise floor due to strong locals > 150-200 kHz away.

Is it time to toss my PL-380 en la basura, or is there anything I can do? :(

Paul......CONGRATULATIONS on hitting # 500 from Europe!! Welcome to the 500 Club!!

As you're well aware...things start getting even tougher with each 100 you hear...but I wish you success in reaching 600 real soon!!

Don't forget to submit your Logs for the 500 Heard Award....and If I remember correctly 500 also gets you the MASTER ULR DX Award as well!!

I'm sure Gary needs the work and won't mind printing you up these 2 Well Deserved Awards!!

Good Show Paul.......

Hi Paul,
 
Congratulations on logging 1650-CJRS on your E100 with the Tecsun 9" loop, and finally receiving station #500! That is an amazing accomplishment from Northern Ireland, especially when you split up your DXing time with the FM band, and set all-time new FM-DXing distance records :-)
 
You certainly have great patience in chasing DX primarily with barefoot Ultralights, and only occasionally with external antenna help. The opposite is the case here, where lack of patience has resulted in some legendary AM-DXing loops (perhaps resulting in the neighbor's lack of patience?).
 
As Rob has mentioned, we would be only too thrilled to award you for your fine DXing accomplishments, if you are so inclined. Great job, and good luck on chasing the next hundred!
 
73, Gary DeBock (in Puyallup, WA, USA)
