Re: Return of the Ultralight TP's

Gary,

That reminds me. I was looking up LW stations in WRTH. There are a bunch in Siberia, running about 100 kW. You'll be able to hear them. Not sure you can get enough wire onto a 7.5-inch rod and still have an effective antenna, but you might toss a toroid onto a PL-380 you've already hacked, and couple a loop into it. Make the winding 2700-3500 uH, measure the inductance of the loop (no tuning cap) and make another winding of the same inductance. Hook it up with speaker wire. LW BC is a lot of fun. Signals tend to remain steady for 30 minutes or more, and can be quite strong. Plus, you don't have as much interference from adjacent stations! The PL-380 works just as well at LW as MW, and I'd like to see more LW ULR activity.

Congrats on the loopstick loggings! Iran didn't give me enough audio last night, but I learned something. The night before, when Iran was stronger, I noticed WBZ-1030 in Boston was very loud about 30 minutes before my sunset. The path to Iran goes just off the New England coast. Last night, WBZ was buried under a Cuban, and never got very strong through the night. When WBZ is competing well against Cuba at my sunset I'll know it's a good night to look for the Mideast at their sunrise. I wonder if you've found similar pointers out there?

Analog radios borrow part of the ferrite rod for the local-oscillator (LO) inductor. You are tuning the radio with the antenna, by "pulling" the LO.  DSP radios digitally synthesize the LO; there are no tuned LO circuits. You could use a separate inductor for the LO, but that only moves another weak link into position, the front-end circuitry. Portables are designed to have gain commensurate with their antennas, and will "saturate" on strong signals.

DSP radios will overload too,. The effect is hard to discern from the usual splatter by adjacent stations. You can demonstrate it with some simple test equipment (two signal generators and calibrated attenuators). Where several strong signals are close together, the radio may sound noisy between stations, because of intermodulation . Shielding the radio in such a way that you can still read the meters (screen wire) or simply taking the radio farther away from the location, will eliminate those stations as possible causes of the problem. Location location location. This article  simply explains the causes.

This PDF  explains how ARRL  measures intermodulation distortion (IMD).  It's more easily done when you can disable AGC, but the article further explains what's happening in our radios in the presence of multiple strong signals. Intermodulation is the product of two or more  strong signals. If you can reduce the strength of one or more of them, you may eliminate the problem.

One of the most-effective ways to reduce the problem is to have as much selectivity as possible before any amplifying stages. That's one reason I persistently insist the antenna should resonate across the band. A higher-inductance but non-resonant antenna may increase indicated signal levels, but lead to IMD problems in areas where there are multiple strong, nearby stations. They might work great where there aren't many strong stations, but crash and burn in places where there are.

Thanks for the report. The distances of your DX reception always amazes me.

Here at my QTH, KGOW is a night-time pest. Despite being 804 km away, it usually owns 1560 from sunset to sunrise.

Hi Guys
 
A brief family holiday/dxpedition to the Steenbras River Mouth  and Betty's Bay  included the reception of two interesting stations from a South African perspective : 
 
1629 1755 AUSTRALIA 3ABN Busselton WA w EE religious programming including "Lift Him Up" at 1830 UTC - fair peaks. The most consistent of the WA X-band stations heard that evening on the 8th April (A personal/South African first).
 
The 400 watt signal was fairly consistent and made it through over a distance of 8 500 kilometres to Betty's Bay with surprising peaks.   A brief audio clip of the reception is available here 
 
1560 0344 U.S.A. KGOW Bellaire TX with a station id slogan as "15-60 The Game". Commercials aired at 0502 UTC included "Venom Energy Drink" and "The Matt Swanson School Of Golf" heard on the 9th April.
 
A recent nighttime power increase from 1 kw to 15 kw with a favourable nighttime antenna pattern would probably help explain the recent reception for the first time (over a distance of 13 936 kilometres).
 
Receiver : Sony SRF-M37V
 
Antenna : 60 metre BOG
 
3ABN Busselton WA 1629 Installation
 
The recent installation of 3ABN's first AM expanded band narrocaster just north of Busselton in Western Austalia provided an opportunity to post a brief article from a broadcasting perspective.  CoDirector Rosemary Malkiewycz kindly included some background info in a QSL reply.  The post includes some interesting pics of the set up and is available here

Hello Gary,
 
Congratulations again on your success during the DXpeditions to Steenbras River Mouth and Betty's Bay, with the very interesting descriptions provided by links.
 
Your reception of both 1629-3ABN and 1560-KGOW is amazing, and reminds us all of what a skilled DXer can accomplish with a simple ULR on an ocean beach. Thanks for sharing your DXing impressions with us, and good luck for more breakthrough loggings.

Return of the Ultralight TP's

Gary DeBock
 

Hello All,
 
It's certainly nothing to shout about, but after the dreary transoceanic conditions of the past week, four fairly healthy TP's showed up on the stand-alone 7.5" loopstick PL-380 this morning.
 
594-JOAK was the strongest of the group with NHK news at 1303, having a signal level approaching its fall strength. 747-JOIB was over and under the 750-KXL splatter around 1301 (mostly under), while both 1566-HLAZ and 1575-VOA Thailand had moderate audio around 1258.
 
These "big guns" will never win any prizes for rarity, but after the extended solar meltdowns, it's probably best to be thankful for what we have :-)

Re: Tecsun PL-360 3" Loopstick Testing

Hi Stephen,
 
All of the AM signal comparisons in the Shootout and Review articles are performed under daytime DX conditions, so that stable ground wave signals are used to judge relative sensitivity and selectivity between ULR models. Trying to compare unstable AM signals at night would be asking for trouble.
 
Fortunately here in Puyallup, WA there are no 50 kw locals, but we do have a Korean-language graveyard pest (1450-KSUH) about 2 miles from here, a 50 kw Tacoma slopper (KKOL-1300) about 6 miles away, and a 5 kw Spanish-language pest (1360-KKMO) about 8 miles away. But none of these really cause the PL-380 (on its 1 kHz DSP setting) to overload here, Stephen. At night, stations can easily be heard 10 kHz up and down from each of these stations-- so I'd agree with Scott that you probably have an issue with your individual PL-380.
 
All of the Si4734 DSP models typically have fairly good resistance to overload, in comparison to the earlier-design ULR's that preceded them. Most traditional Ultralights overload badly when inductively coupled to the 9' box loop here, but the Si4734 models are highly "crunch-resistant," and behave very well (even with the RF onslaught). With analog models like the SRF-59 and the R9012 you can actually tune the radio simply by tuning the 9' loop (when their distance is within 5 feet), but the DSP Ultralights typically receive only on their tuned frequency, no matter what frequency the huge loop selects.

Now, a quick reply to Gary's post, as I don't want to make two separate posts....

Any chance you could do daytime comparisons when the signals are more stable? Also, any chance that you could go to somewhere within a km or two of some of your 50kW locals and check the performance there? I'm about 6-10 miles away from a couple locals, and the RSSI readings when between channels are unacceptable at around 30-40 dBu. Inside a car in a rural area (where weaker signals would be attenuated on top of that), they read 15 dBu in between channels.
As for backyard space, I probably have about 40 feet (north-south) by 120 feet (east-west) or so of area where I could erect temporary antennas. Also I'm probably about 5 miles away from a commuter airport, and not exactly in the flight path of the international airport 15 miles to the west, so I do have a little bit of room to elevate an antenna. (I would be a bit wary of erecting a full-wavelength guyed tower for 153 kHz, though.)

Arrgh, I dumped it, but thanks. There was a lot of noise and her voice was monotonic and low in pitch. Just couldn't process it enough to get anything clear. It sure wasn't Portuguese, Arabic or French. Right after TOH there was some kind of gong, not very loud (their modulation seemed low and lacking high frequencies), like something that would separate news items or signal the beginning of a program. Sistan and Baluchestan province (the poorest and most undeveloped region in Iran, according to Wikipedia) has mostly Balochi speakers, and I'm wondering if that was the language, though it's the Iranian national network, so probably Farsi. I'm going to look for it earlier tonight, try to catch it at their sunrise.

Listening on 783 for Mauritania last night, at 0200Z I heard a woman speaking in a fairly low-pitched voice, with low modulation. It didn't have the cadence of French or Arabic, but I couldn't get anything out of the recording. Checking DX Atlas this morning, I saw that sunrise in Tehran was  at 0201Z! Checking WRTH I found a 100-kW station in Iranshahr, Iran, with SR about 0135Z, so it's possible that's what I heard. Never did hear Mauritania. The way conditions have been going it may be too late in the season for Iran, but you never know.

Re: Tecsun PL-360 3" Loopstick Testing

Well... right here just barefoot I am far enough away so that I'm not quite getting 50 dBu in between channels, but it is often touching 40 - 45 dBu. I don't have to boost it much to get 50 dBu, though - just using the SAT is sufficient for that. (By comparison, inside a car, which naturally attenuates signals somewhat, the barefoot reading in between channels is around 15 - 20 dBu.)

I took the liberty to do some comparison on several local frequencies an hour or two ago. Comparisons are: inside the car (barefoot) | outside (barefoot) | outside (with Select-A-Tenna). (Then there'll be one more noted farther down the post.) All were done between 10:15pm and 11:45pm using relatively stable local signals using 1 kHz bandwidth.

600 (KOGO): 47,25 | 63,25
690 (XEWW): 37,25 | 56,25
747 (off KFMB): 24,00 | 37,00
760 (KFMB): 58,25 | 63,25
774 (off KFMB): 19,00 | 39,00
800 (XESPN): 31,25 | 47,25
860 (XEMO): 33,25 | 51,25
895 (off KECR): 15,00 | 35,00
910 (KECR): 49,25 | 63,25
925 (off KECR): 15,00 | 35,00
1040 (KURS): 23,22 | 40,25
1116 (off KSDO): 22,00 | 37,00
1130 (KSDO): 50,25 | 63,25
1143 (off KSDO): 22,00 | 37,00
1170 (KCBQ): 44,25 | 60,25
1210 (KPRZ): 30,25 | 45,25
1240 (KNSN): 36,25 | 52,25
1270 (XEAZ): 27,25 | 43,23
1310 (XEC): 26,19 | 42,25
1360 (KLSD): 40,25 | 57,25
1420 (XEXX): 29,25 | 47,25
1470 (XERCN): 35,25 | 54,25
1550 (XEBG): 15,14 | 32-35,25
1630 (XEUT): 24,25 | 40,25
1700 (XEPE): 33,25 | 50,25

Then, I took the strongest one, 760 (KFMB), and gave the radio a bit of an extra boost to see what would happen. First, I used just the SAT tuned to 760, while tuning the PL-380 (using the push buttons as the tuning dial is broken). With only the SAT, I was getting 50 dBu in between channels from about 665 to 1015 kHz, and 49 dBu from about 545 to 1495 kHz. Also, the 2nd harmonic (1520) was reading 47,25 with just the SAT.

Then I put it to the ultimate (well, for what I had access to) test. I put the SAT and PL-380 up against a power pole - one of the ones with a ground wire running down it inside the narrow diameter cylindrical wood piece running up the height of the pole.
Now to give you a little idea of how much of a boost that is... back several years ago KCBQ, a local blowtorch pest, used to have their transmitter site a few miles closer, AND had a higher ERP toward me. When taking my previous radio (Panasonic RQ-SW20) barefoot on the road on which their transmitter property was (about 5 to 6 miles north of me), sure 1170 would splatter across a good portion of the band.
However... use the SAT and power pole outside my house several miles away from the transmitter.... and I could actually get the audio, while tuned ON the assigned frequency, to overdrive, something I couldn't do barefoot on the road right by their transmitter!

So... I did the SAT + Power Pole test on 760... and here's the results:
50dBu spread: 153kHz to almost 3000 kHz (yes, I checked the LW and SW bands)
harmonics: 2nd was 63dBu, 25dB S/N, 3rd couldn't be tuned (2280), 4th to 8th were 63dBu (but not 25dB S/N), 9th was about 57-60, 10th (7600 kHz) was about 62 dBu or so, and I didn't check any higher than that.


Now... for some RSSI readings I took a couple days ago in the early afternoon (2:00 to 3:45 pm) in my back yard. Most of them are barefoot, and I'll note SAT readings on some channels.

Well... turns out I listed more than just a few of my strongest stations. ;) As for demoing a G8, I actually had bought one before I bought the PL-380, and tested it... but right now I'm not sure I can find any notes I had made - I think I may have deleted them or something accidentally.

I think what I need is better Q AND better sensitivity. Originally, I was planning to use the radio inside my pants pocket (which is deeper than it is wide, hence the desire for a vertically-oriented radio), with headphones connected, while I was going around town either walking, taking the bus, on my bike (during which I'd only have the headphones on loosely), etc. A few stations I wanted to be able to listen to mid daytime were 560 KBLU Yuma (pest is 570 KLAC), 590 KTIE San Bernardino and 610 KAVL Lancaster (pest for both is now 600 KOGO's IBOC), 680 KNBR San Francisco (pest is 690 XEWW), 700 KWLW North Salt Lake City (pest is also 690 XEWW), 1110 KDIS Pasadena (pest is 1130 KSDO), 1180 KERN Wasco-Greenacres, which is near Bakersfield, CA (pest is 1170 KCBQ), 1580 KMIK Tempe, near Phoenix, AZ (pest is co-channel KBLA Santa Monica), among others. All of them were virtually completely undetectable - not even so much as a carrier (with the exception of KDIS, but ONLY if KSDO was off the air) on my previous barefoot radio, the Panasonic RQ-SW20, which I still have.

Also, with a good loop antenna (something comparable to or better than what Bruce Carter has used - he was able to get Chicago AMs from TX in the daytime), I was hoping to get daytime loggings of 750 KXL (pest is 760 KFMB), 820 WBAP (pest would be 820 XEVMS Mexicali), 850 KOA, 1000 KOMO (pest would be 1000 KCEO Vista), 1080 KRLD (pests would be 1070 KNX (and their IBOC) and 1090 XEPRS), 1160 KSL (pest would be 1170 KCBQ), 1190 KEX (pest would be KXMX Anaheim), just to name a few... and at night with a good loop I would like to be able to regularly bring in 650 KENI Anchorage, AK and WSM Nashville, TN (pest would be KFI), 660 WFAN New York (pest would be KTNN Window Rock, AZ), bring back 670 KBOI Boise (they changed their pattern - used to be a regular here before that, pest is now KIRN Simi Valley) and WSCR Chicago, 700 WLW Cincinnatti, 720 WGN Chicago (have logged them once, pest is usually KDWN Las Vegas), 750 KFQD Anchorage and WSB Atlanta, 760 WJR Detroit (pest is local KFMB), 770 WABC New York, 880 WCBS New York (pest is KRVN Lexington, NE), 1000 WMVP Chicago, 1500 (former WTOP) Washington, DC (I have heard KSTP St Paul once or twice), just to name a few.


Scott, what part of the country do you hail from? (I think Gary DeBock is in the Seattle area or somewhere south of there, but I'm not sure.) I'm basically about 10 or so miles east of San Diego, CA - basically south of El Cajon and east of La Mesa, within a mile or so of 32°45'40"N 116°56'50"W, which is on a school campus not very far from me. (Also I'm curious as to what typical daytime RSSI readings of stations (and in between) are where you are - I understand you got a PL-380, right? or was it a PL-310, PL-360, or PL-300WT/G8?)


Now, a quick reply to Gary's post, as I don't want to make two separate posts....

Any chance you could do daytime comparisons when the signals are more stable? Also, any chance that you could go to somewhere within a km or two of some of your 50kW locals and check the performance there? I'm about 6-10 miles away from a couple locals, and the RSSI readings when between channels are unacceptable at around 30-40 dBu. Inside a car in a rural area (where weaker signals would be attenuated on top of that), they read 15 dBu in between channels.
As for backyard space, I probably have about 40 feet (north-south) by 120 feet (east-west) or so of area where I could erect temporary antennas. Also I'm probably about 5 miles away from a commuter airport, and not exactly in the flight path of the international airport 15 miles to the west, so I do have a little bit of room to elevate an antenna. (I would be a bit wary of erecting a full-wavelength guyed tower for 153 kHz, though.)

Stephen,

I'm wondering if maybe there is something else wrong with your PL-380 besides the broken tuning knob. I really can't think of a reason why you are seeing 50 dBu in between channels. The PL-380 might de-sense in the presence of strong channels, but it shouldn't overload or distort, which is what could "fill-in" the gaps between channels. What are the RSSI readings on a few of your strongest stations?

Maybe you could demo a G8 at a local Radio Shack to see if you get similar behavior?

In any case, as long as you see a 50 dBu floor, an antenna with more signal strength will not be helpful. You need either better Q or better nulling.

Hi Stephen,
Thanks for your comments on the PL-360 experimentation.
In answer to your questions, I do plan to post comparison RSSI and S/N readings between the stock and custom PL-360 plug-in loopsticks (3" and 7.5") in an upcoming PL-360 review. After the 3" x 3/8" ferrite bar plug-in loopstick was completed last night, I did run some quick comparison tests with the stock PL-310 and PL-380 models on some relatively open AM night frequencies here (521-INE beacon, 1610-TIS mix, and 1700-Tijuana) to verify that the PL-360's AM performance (with the 3" loopstick) was significantly better than the stock Tecsun models. I think that this 3" loopstick design would also have good potential in the PL-380's battery compartment as a "stealth" antenna,
Maybe you have room to construct a twin coil in the batt compartment??

What would the construction of a twin coil look like??
