Long Term DX Project - 22/05/2021

Paul Blundell
 

Date: 22/05/2021
Time: 1:15pm
Location: Home, Launceston Tasmania.
Radio: AR-1733 / 3” FSL
Notes: A early afternoon session. Using my 3” FSL I was able to log the below frequencies for my long-term DX project. Overall, I was happy with my results with only 2CA on 1053kHz not being logged at all. The three 50kw big guns were all logged at excellent signal levels. I have noticed of late that the HPON station from Geelong on 1341kHz is normally slightly stronger than the other stations around it.

FM Loggings - 22/05/2021 - Three Way Test

Paul Blundell
 

 Over the weekend I spent some time in my backyard running a three way test of my Digitech AR-1733, TEAC PR130 and DAB-P9.
As can be seen the Digitech AR-1733 was the best performer, both the PR130 and DAB-P9 missed some stations.

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

This solution looks very interesting from the perspective of an experimenter being able to play with the parameters. Right up my alley, as I love tweaking.
But how good is the radio overall?
Like in many cases where the same chip is used, implementation is important. Not necessarily limited to access to the chip's functionality. How does it sound? Does it use the whip for FM, or the headphone cable?
BTW, I am not familiar with the Yamaha T84. I could not even find anything on it with a google search. So that comparison does not help me.

The best long lasting 18650 is the LG MJ1 but not easy to find at least at a good to reasonable price

Suggest looking for a name-brand item, Tenergy is an example or one of the flashlight brands like Nitecore - as another poster mentioned. In Canada www.batterycanada.com has Tenergy, if in US might try Nitecore website, they seem to have a good selection. In any case look for a cell with protection (against overcharging/discharging etc.). A name-brand 18650 probably won't be the cheapest available, e.g. a Tenergy 3500mAh from BatteryCanada is ~ 25% of the price I paid for my D808.

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

Peter 1956
 

Jorge, no I didn't try that because it was still under warranty.
Here it's unlikely I'll get Es with RDS on a portable. The only longer telescopic rods I have won't fit anyway. I could attach a 3m wire to the whip, that works for FM.

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

Jorge Garzón
 

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.

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.

Careful with batteries you buy on ebay, they can be imposters/fakes/junk. I have been using nitecore 18650 batteries for years and have no problems, and theyre based/at leats mostly made in the US.,

Re: Headphones?

I prefer over-the-ear headphones...but have also found that Apple EarPods work well for me. I generally don't like earbuds, but the Apple ones have decent sound and, most important, can actually stay in my ears!

Re: Sangean DT-800

Mark Roberts
 

It's a good radio: my quibble with it is that the threshold for FM stereo reception is set rather high. For example, you might get stereo reception on a Tecsun model (or some other model) but the Sangean will stay in mono, even though signal strength and sensitivity are comparable. This seems to be the case with all the Sangean DSP-based models. For example, the DT-160 is the same way.

Hi all,

Just received my Sangean DT-800 in the mail and what a gem it is!!!

I find it quite sensitive on AM/FM with a nice set of features that I find very useful.  It even has the ability to turn off "muting".  Nice!  :)

I'm finding it to be the best of my radios in this "handheld form factor" so far, narrowly beating out my CCrane Pocket, that I also love!

Anyone else like this radio?


Johnny


Re: Sangean DT-800

Mark Roberts
 

The DT-250 is not available in the United States (I've looked - I like the silver color - I'm shallow) Probably the closest equivalents are the DT-400W or the DT-200VX.

Re: the CC Pocket. Note that there are two versions. The first version had poor AGC on AM (mediumwave). The second version was much improved. You can distinguish the two versions this way: version 2 has numbers molded into the five front-panel buttons. Also note that the functions of the front-panel buttons are listed in a label that's on the other side of the battery-compartment door.

Hi Jorge,

Thanks for the great comments on the DT-800 vs DT-250.

I don't know if we can get the DT-250 in the US ???

I like my CCrane Pocket, but honestly I find the dial volume to be the thing that I like the least.  To me sometimes it seems a bit "crackly" when adusted.

Sounds like the DT-250 is a real keeper!  I'll be on the lookout for one to purchase.

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

Johnny
 

Hi all,

I have been performing some VERY informal side by side comparisons of these three radios on FM.

I must admit that the DT-800 and the R-108 are both equally excellent at FM reception and better than any of my other UL radios and most of my larger portables.  The only caveat with the DT-800 is that because of the need do use the earphone adapter as the antenna, you have to be able to move the cord around a lot to get the best reception, but it is pretty darn good at receiving!

Both of these radios get 95% of the channels that the CCRadio 2E gets, so for me the only real reason to play around with the CCRadio is if you want to here everything possible, but are okay to abandon the UL concept considerably.

Question to the group:  Could anyone recommend an UL radio that would be better on FM (in your opinion, I would never hold you to anything), than the R-108 or the DT-800?

All of this is just my rookie feedback on my mileage with these three radios, your mileage (kilometerage?) may vary!  ;)


Thanks,



Johnny

Portable Ultralight DXing Session - 22/05/2021 - Talbot Road Lookout

Paul Blundell
 

Date: 22/05/2021
Time: 9:00am
Location: Talbot Road Lookout, Launceston Tasmania.
Radio: AR-1733 / 3” FSL
Notes: A morning session at one of my preferred DXing locations. I firstly undertook a session for my long term DX project, these results were as expected. The three 50kw big gun stations from Victoria all hit “excellent” signal levels. 2CR on 549kHz only managed a “weak” signal level and 2CA on 1053kHz was not logged at all. Moving up the band, 3KND on 1503kHz was a bit of a surprise to log at “good” signal level. Both the HPON stations could only manage “average” signal levels. 
I had my "second operator" along for the session today and his excitement was great, I look forward to having him along for more sessions in the future.
