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

Johnny
 

Hi all,
 
Just picked up a Sangean PR-D18 purely for it's FM reception.
 
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
 
For what it's worth!
 
Johnny

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!

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

Johnny
 

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!

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.

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!

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.

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.

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.

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

Phil Pasteur
 
Edited

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.

Re: Good source for 18650 batteries?

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.

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.

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?

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.,

Mark, 

I found a set of 4 or 5 on ebay that came with a bonus wall charger and a super-bright pocket flashlight, for around $12.00. Sorry I can't provide more details but my purchase history doesn't go back that far. 

Good luck,

The 18650 batteries that came with my XHDATA D-808 radios (2 of them) have turned out to be lousy. Even when the radios are not in use, they discharge very rapidly. This is true even though I have tried different makes of battery. The stock XHDATA battery has been slightly better but still not great.

So here's my question - does anyone on this list know of a good source for these batteries? Amazon has been a bust for me. Thanks!
