Interesting project! Did you try the DT-880's Narrow FM bandwidth setting for improved selectivity?

That's actually works nicely. I do that in my radios and also in my
old car that I drive only on special occasions. From my experience, it
actually prolongs battery life

Re: FM DXing - Sangean PR-D18 vs CCRadio-2E - Simple Side-by-Side Test

Jorge Garzón
 

Hi Johnny, 
Both Sangean, PR-D18 and PR-D19 are excellent performers on FM and very good on MW (AM). The bigger one with two speakers offers a deep and rich sound that fill a room, but because of that is a battery eater, so better use an AC/DC adaptor. Battery life when connecting earphones is much longer then.

Both models have identical performance on both bands despite the size, and both are out of UL and Small Portable categories, strictly speaking. 

As 'Sangeans' their features come into the scene: Very good sensitivity and reliable selectivity. Surprisingly here sensitivity on FM is brilliant and beats easily the CC pocket, being even slightly better than the DT-800. Also selectivity is better than the Sangean average as they offer an useful narrow/wide filter position and 100/50 kHz steps. It is a pity that the whip reaches just 67 cm unfolded and undoubtely with a longer one (100/115 cm), signals would be even better. 

I tested Sangean PR-D19 on MW with excellent results and some of the videos I made can be found in my Yotube channel. I recorded one about its FM performance Vs a big TECSUN S-8800. That was one of the first clips I recorded and my poor skills as a cameraman are noticeable there but I wanted to test both receivers with a close FM txer and two more, a low-powered and one afar.

Have in mind that the TECSUN telescopic reaches 100 cm and PR-D19 reaches just 67 cm. The price of the bigger radio multiplies by three Sangean's. And even more important, I discovered here that even switching off a receiver, the unfolded whip interacts with the unit being tested, so telescopic antennas must be keep apart to avoid a coupling effect. 


¡ Buen DX!

I have to admit that this little radio, while ever so slightly bigger that the true UL definition (very close though), has EXCELLENT FM reception!
 
I would say that in my recent (very non-professional) tests between the PR-D18 and the CCRadio-2E, the PR-D18 was very equal to the CCrane, with each radio sometimes hearing a few things that the other could not.  

The Sangean definitely was as good as the R-108.
 
Reminder:  This test was only performed on the FM band as this was my target!!!
 
Costs:
  • Sangean PR-D18 - $50-ish USD
  • CCRadio-2E - $160-ish USD

WNJC 1360 Summertime High-Octane DX Tests

Les Rayburn
 



The Courtesy Program Committee (CPC) of the NRC & IRCA is pleased to announce that WNJC 1360 kHz in Washington Township, New Jersey will be conducting maintenance tests on their automation systems and other equipment during the summer, resulting in some opportunities for DX’ers to log this station. 

Chief Engineer Duke Hamann sent the following notice regarding the summer schedule: 

JUNE SCHEDULE

Nightly for the entire month. June 1-June 30th starting at Midnight EDT (0400 UTC) for one hour. The Burke Controller will be programmed to switch to daytime pattern and power during that hour. Daytime power is 5,000 watts. 

The test material will consist of a brief voice announcement, followed by nothing but Morse Code ID’s at 800 hz, 900 hz, and 1,000 hz. Most of the CW will be high speed at 25 WPM. 

There will also be plenty of sweep tones, 1,000 hz long duration tones, and off hook sound effects. No music, voice, or other distractions. Similar to the KCUP test earlier this year, it should provide the optimum chance to cut through the summer static. 

WNJC AM Coverage Map

JULY SCHEDULE 

July 1st through 7th. Midnight EDT (0400 UTC) to 5 AM EDT (0900 UTC) “Hybrid” DX Test. Test will be daytime power, 5kw but into an omnidirectional pattern. 

Test material will be limited to CW only at 800 hz, 900 hz, and 1,000 hz along with simultaneous transmission of FT-8 computer mode transmissions. 

FT8 is used by amateur radio operators to communicate over long distances at very low power levels. Receiving it is even easier, and can literally be done by putting a microphone from your computer close to your receiver’s speaker. Using FT8 WNJC was received nationwide and in several countries last year. How to get started, try these tutorials or search Google for “Getting Started in FT8.” 


July 4th Special Test. On July 4th WNJC will conduct a special Independence Day event starting at 8 PM EDT (00:00 UTC) until 6 AM EDT (1000 UTC). 

Test material will consist of voice ID’s, jingles, Morse Code IDs, sweep tones, along with special patriotic music and sound effects. 

To assist in keeping DX’ers informed of last minute changes and to better track receptions of the station during it’s maintenance, CE Hamann has created a Facebook group: 

WNJC DX Test Facebook Group:


QSL INFORMATION

QSL’s for the June tests and July 1-7 Tests will be handled by the Courtesy Program Committee of the NRC/IRCA. Our QSL requirements are very specific: 

  • All requests must be submitted via e-mail to: les@...
  • QSL requests must include a recording of the best two minutes of your reception in either .MP3, .WAV, or .MP4 video. No written reports will be accepted for verification. 
  • Requests must be received by August 1st. 
  • Only one QSL per DX’er regardless of how many times you receive the test (s). 
  • If you use a remote SDR or receiver to log the test, we will honor only one QSL per DX’er. No multiple QSL requests. You must clearly state the location of the receiver that you used to receive the station. 

The July 4th Special Test QSL requests will be processed directly by John “Duke” Hamann, Chief Engineer of WNJC. The requirements are: 

  • All requests must be submitted via e-mail to: duxpond.kc2dux@...
  • Only one QSL per DX’er. You may apply for the July 4th Special QSL even if you have already received the test earlier.

Notes: A early afternoon session during my daily walk. Signals were down on normal with nothing being received at anything better than an “average” signal level. 3GG on 531kHz was only logged at a weak signal level. 3WV on 594kHz was also only logged at weak signal level, this was surprising for a 50kw station, the other two 50kw stations hit average signal levels.

Re: Additional on CCrane Skywave SSB reception of NOAA weather radio frequencies . . . probably for radio nerds only.

Mark Roberts
 

162.55 was indeed the first weather-band channel, with 162.40 as an alternate. I have a Zenith Royal 92 "Weather Commander" AM/FM radio from 1968 (American-made, probably in Chicago) and it can tune that frequency on the radio. Reception of that particular frequency was crystal-controlled. Still works though it's definitely NOT an ultralight, not with 6 "C" batteries!


On Sun, May 2, 2021 at 4:16 AM Paul Blundell <tanger32au@...> wrote:
I did read to the end and thought it was interesting about the difference between the numbering of the channels.

With regard to the NOAA weather radio reception of the CCrane Skywave SSB, here's some info that I posted Radio Reference that might prove useful for anyone for whom NOAA weather radio is a high priority.

As a friend put it: "This is stuff only a radio nerd would chase down."

What follows is a compilation from various posts in the thread:

Perhaps I am the only guy on planet earth with a "kinda" interest in DXing NOAA weather radio, but there you have it, but we'll get to the interesting part in just a moment.

Today I find myself in Sodus, NY, in the western part of the state, near the shores of Lake Ontario. Rochester, NY, is a bit further to the Southwest. I have with me the following: an Icom V80 with a sharply tuned (I think) commercial antenna that works great on my home repeater (146.94) in Troy, NY; a Uniden BC125AT with a Diamond 77 antenna, and a CCrane Skywave SSB. All receive the NOAA weather channels.

Early this AM, I checked www.wunderground.com for weather in the Sodus area. Snow is expected overnight. So I grab the Uniden 125AT, activate the weather scan function, and find that it receives NOAA weather radio channels 1, 2, and 3, and the audio sound great through my headphones. I try stepping through the weather radio channels on my Icom V80 and find that it receives channels 1, 2, and 3 but with just a wee bit of static in the background. I try switching the antennas between the 125AT and the V80, and there is no appreciable difference.

Now, here's the interesting part: I try the same trick on the CCrane Skywave SSB with its telescoping whip fully extended, and it receives weather channel 1 just fine with excellent audio through the headphones. But channel 2 is way down in the soup, a hair above "barely audible." I try waving the Skywave around, point the whip antenna in different directions and orientations to see if I can improve the signal. I succeed only in nulling it out. Weather radio channel 3 is not audible at all, but channel 4 is coming in well, and so is channel 7 . . . and the other two radios were not receiving channels 4 and 7 at all.

Frankly, I don't know what to make of this. To be clear, I was able to hear that forecast that I needed to hear -- for Wayne County, NY -- on all three radios. But why would there be such a stark difference between the CCrane Skywave SSB and the other two radios?

The V80 and the 125AT "agree" with each; both are receiving NOAA weather radio channels 1, 2, 3. The CCrane Skywave SSB appears to be the anomaly, receiving channels 1, 2 (barely), and 4 and 7, which the V80 and 125AT did not receive.

I just checked, and the NOAA weather radio frequencies occupy a fairly narrow spread: each channel represents one of seven frequencies between 162.400 MHz to 162.550 MHz.

All three tested in my lap at the same location and then tested in another room within inches of each other. I turned one radio on, checked the channels it could receive, turned it off, then tested the next radio, etc. Same results in both cases.

Then one of the respondents to the thread posted: "Did you check the actual frequencies received on the radios? Some radios number the channels from lowest to highest frequency and others use the NOAA assigned channel numbers."

I responded:

Hmmmm. Interesting idea.

Modern Survival Blog -- https://modernsurvivalblog.com/weather-preparedness/noaa-weather-radio-channel-list/ -- reveals that NOAA weather channels may displayed in two different ways, depending upon the manufacturer: chronological or in increasing frequency order.

The Uniden displays Channel numbers and frequencies, so: Ch. 1, 162.550; Ch. 2. 162.400; Ch. 3 162.475. The Icom V80 lists only channel numbers, but no frequencies. However, it receives the same channels as the Uniden.

This appears to be the chronological sequence – the sequence to which the radio frequencies were allocated over time to the service. This ordered sequence is used by (some) weather radio manufacturers.

1=162.550 Mhz
2=162.400 Mhz
3=162.475 Mhz
4=162.425 Mhz
5=162.450 Mhz
6=162.500 Mhz
7=162.525 Mhz

The CCrane Skywave SSB lists only channel numbers. BUT, if it follows the weather radio channels in increasing frequency --

1=162.400 Mhz
2=162.425 Mhz
3=162.450 Mhz
4=162.475 Mhz
5=162.500 Mhz
6=162.525 Mhz
7=162.550 Mhz

Then the CCrane receives Ch1, 162.400 (which is Ch. 2 on the other two radios); Ch 2, 162.425 faintly (Ch. 4 on the other radios), Ch 4, 162.475 (Ch. 3 on Uniden and Icom), and Ch 7, 162.550 (which would be Ch. 1 on the other two radios).

So all three radios are receiving the same frequencies, but with different channel numbers assigned to them . . . and the CCrane appears to be a hair more sensitive, also receiving the 162.425 channel very faintly.

As Inspector Clouseau would say: "The case is sol-ved."

Finally, if you have read this all the way to the end, one might make that case that you have tested positive for being a radio nerd.

Cheers, Jock



Re: Improving Pocket UL FM reception

Hi Jorge,

What a great test!  I read the whole article with great interest, because I am going to test the same thing!

I just ordered a plug in extendable antenna (two days ago) and a set of "Rabbit Ears" to test in this same manner.

I love the idea of the splitter as I was not sure if this would work or not, but was concerned about strain.

Very cool!

Re: Good source for 18650 batteries?

vbifyz
 

My PL-880 started draining batteries while off recently. Before this began, the battery would stay charged for months if not used. Now there is 15mA constant discharge current. The worst part is that it doesn't stop when the voltage is below 3V, killing the cell. I had to throw away 2 cells before I realized what's wrong.
As for the source of 18650 cells, the best source for me is tested cells from discarded laptop batteries.

Re: Sangean DT-800 vs Sihuadon R-108 vs CCRadio 2E

gary_thorburn
 

Yes, FM on the Sangean DT-800 is very good. Two comments about the DT-800 AM:
1) Soft Mute on the DT-800 can be completely disabled by a simple menu setting! Very worthwhile.
2) On my unit, in AM, the LCD display makes some hash noise when playing thru the speaker. But I hear none of that when using headphones.

Just to say my xhdata d808 has the same issue so must be a common fault. I wouldn't mind getting the digitech but at almost twice the price with the new annoying 20% vat added on everything bought outside the UK it puts me off somewhat!

Thanks, Jay (and all). I have suspected that for some time. However, I keep reading the glowing reviews of the XHDATA which do not mention this problem at all. When I change out batteries, I do see variations in battery life, but not enough to really solve the problem. I bought my two units about three months apart, from the same reseller in Israel. It's possible that reseller had a bad batch, but it doesn't add up for me.

While a very good radio (AM and FM), the rapid discharging (2 to 3 weeks at most) is very frustrating and I'm about ready to junk the radios. I also have the Digitech AR-1780 (also two units), which is almost the same radio except that it uses ordinary AA cells, and neither unit has the rapid discharging problem.

Beware of battery draining while the radio is off. I have had two radios which did this and in both cases the radios were defective...replacements cured the issue. The test is to take the battery out of the radio and see if it still discharges.

This seems a more likely scenario than several batteries which self discharge on their own,

FWIW.

Re: Sangean HDR-14 UL HD AM/FM Radio - What do you think?

Mark Roberts
 

Hola, Jorge -
The situation in the United States is not one that would indicate that HD is the future of radio. In the San Francisco Bay Area, one of our two National Public Radio stations has turned it off. The commercial FM stations running HD have been abandoning their HD-2 channels. The all-sports stations on FM (we have two of those) have turned it off - the time delay makes it difficult for listeners to bring their radios to the ballpark or stadium to hear the play-by-play of the action that's in front of them. There are still a couple of interesting formats on HD-2 stations, but in other cities, HD-2 channels seem to be used primarily for AM simulcasts. No AM HD here - the nearest is in Sacramento (about 130 km away). The Federal Communications Commission has authorized digital-only AM stations, but that's a relatively new development. The big commercial chains (Audacy, iHeartRadio, Bonneville, Cumulus) are the ones who've kept HD alive. As for receivers, many new cars can receive HD signals. However, that's not widely promoted. I bought a car two years ago; the "infotainment system" can receive HD but it was turned off by default. I had to go through the menus to find the setting to turn it on.

Ultimately, programming drives adoption of anything new in radio. In this case, one of those HD-2 channels in San Francisco has a format that no one else has in the area, and I like it, so I've bought a couple of radios and a tuner in order to hear it. If I lived in Albuquerque (New Mexico), where there are very few stations with HD broadcasts (a bit odd since Cumulus owns the top stations there), it would be a different matter.

I know some Mexican stations are also broadcasting HD; I don't know about Canada. You're right, it's definitely not a worldwide standard. I personally think it's a mistake, but we Americans can make a mess of broadcasting standards when we try!

¡Saludos!

Hi Mark, 
Well, there is no HD AM stations here in the Old World and never will have! I bought mine from the EUA because, despite its size, it had PI decoding capabilities. Unfortunately the RDBS and RDS systems are not compatibles in between them. That's funny as sometimes I got US calls when internally receives some RDS PI codes that coincide with a W... or a K... call in NA. 

But it's a good receiver to go bushwalking, ultralight with good sound, very easy to carry in my rucksac and receives PS, CT and RText opening these subcarriers easily. 

Peter, what about to change the Eton Traveler whip for a longer one? This will improve the sensibility of the receiver compared to the other ones. Did you try this?

It's hard to find AM stations broadcasting in HD. There are none in the San Francisco Bay Area, for example. KCBS (740 kHz), KGO (810 kHz), and KTCT (1050 kHz) tried broadcasting it at various times but ultimately discontinued it. KNBR (680 kHz) could not broadcast it at all, according to my understanding, because the antenna system could not pass the bandwidth required. KHTK Sacramento (1140 kHz) is close enough for an HD signal to be detected, but not strong enough to lock into the signal. I was in Denver a few years ago, had my HDR-14 with me, and got OK results. The sound quality will depend upon the quality of the station's encoding: it's really quite variable, more so than for FM.

It will be interesting to see how it does with the digital-only stations (what few of them there are) that are starting to convert from analog.

For radio collectors: the Sangean SG-108 is the same radio, but in a whitee  case with gray lettering.

As somewhat a collector of IBOC ("HD Radio") sets I purchased this upon its release. A miniaturized version of the HDR-14, crammed into the cabinet used for the Sangean DPR-65 FM/DAB+ portable, there had to be some design compromises. Your intended comparison sets should prove to be an interesting exercise as the others are really aimed at different market segments - apples and oranges. The HDR-14 is not a DX rig but aimed at the casual program listener who has HD stations nearby and wants to take advantage. Frankly if you're outside of North America I can't see any reason to buy it over other postabls unless you are a collector .... but then, many of us are!

When this model was introduced I posted to the SWL blog a quick comparison with its direct competitor - the NiceTex ("SPARC" "Audiovox") SHD-TX2. In the end the NiceTex is marginally a better performer on RF and has much better audio from the speaker due to its passive radiator design. It was never well distributed though and unfortunately seems to have been silently discontinued along with the majority of their private label portables.

The HDR-14 is quite competent on FM which is probably true of most portables designed in the last few years. Its HD capture is really good, which does require very good sensitivity. AM performance is hampered by a small ferrite antenna and rather wide selectivity - again reflecting the design choices made in its market position and re-using a cabinet that did not even have AM section in its original configuration. There are quite a few birdies on AM which may or may not matter depending on whether you have stations which overlap those frequencies. I live in an area in which one of the last remaining AM-HD stations is still on the air, and it does handle it very well. I even snagged AM-HD Dx occasionally from a station ~75 miles away or so.

It is somewhat of a battery hog though, and true to Sangean's design philosophy of beating existing circuit designs to death, still sports the best LCD display technology that the 1990's can offer.


Re: Good source for 18650 batteries?

Thanks, Jay (and all). I have suspected that for some time. However, I keep reading the glowing reviews of the XHDATA which do not mention this problem at all. When I change out batteries, I do see variations in battery life, but not enough to really solve the problem. I bought my two units about three months apart, from the same reseller in Israel. It's possible that reseller had a bad batch, but it doesn't add up for me.

While a very good radio (AM and FM), the rapid discharging (2 to 3 weeks at most) is very frustrating and I'm about ready to junk the radios. I also have the Digitech AR-1780 (also two units), which is almost the same radio except that it uses ordinary AA cells, and neither unit has the rapid discharging problem.

Beware of battery draining while the radio is off. I have had two radios which did this and in both cases the radios were defective...replacements cured the issue. The test is to take the battery out of the radio and see if it still discharges.

This seems a more likely scenario than several batteries which self discharge on their own,

FWIW.
