Re: Local Power Lines and DXing

Jorge Garzón
 

QRM is our main nightmare these days, no doubt! 
But I am still shocked with electric lines in Australia, Canada, the States together with some EU countries. When I lived in Oz and later visited the USA and Canada, I found electric poles and air cables a real mess. Fortunately, here in Spain electric distribution lines have to be buried in urban areas and/or encapsulated to avoid crossing streets, parks and open areas. Of course there are still some to be arranged but the most of them are well organised. 

Unfortunately, this is not an 'insurance' to avoid QRM as house appliances, street lights, house IF filters (none) or transformers are still there, so being a DXer or serious radiolistener involves a carefully place to live or enjoy radio and nature most of the times. 

¡Buen DX!

Re: TEAC PR130 V Digitech AR-1733 - Head to Head Testing - December 2020

Terrific review, Paul...comprehensive and clearly presented...

Over the past few months I have been making good use of my TEAC PR130 and Digitech AR-1733. I have completed a shootout of them over the past couple of weeks and present the results below.

FEATURES: 
Both these radios fit in to the ultralight radio category, the TEAC PR130 retails for $34.95 and the Digitech AR-1733 is $79.95.

Physically the PR130 is a much smaller pocket sized radios, this I find fits in to my pocket well and it often comes out and about with me. The AR-1733 is a larger radio and it better suited to bed side / serious DXing and listening. The lack of a full keypad on the PR130 is due to the much smaller size. The limited buttons it does have do work well and to my mind do work in a logical fashion. While the AR-1733 does have a full keypad for frequency entry, I find myself most using the side mounted tuning knob.

The PR130 only covers the AM and FM broadcast bands, the AR-1733 covers these, plus the long wave, shortwave and VHF Airband, the later of these is an interesting inclusion and makes for some interesting listening. I often leave mine on our ATC frequency overnight as it makes for some good background noise.

Both radios take two batteries, in the case of the PR130, these are AAA, the AR-1733 takes AA, these provide much longer run times. In both cases I have found the battery life on both radios to be very good. On the AR-1733, it does exhibit some strange behaviours when the batteries start to get low, I always keep a spare set close by. The AR-1733 is also a little sensitive to rechargeable batteries, once they get a bit of age and usage, they don’t work as well with this radio, the PR130 happily runs on two AAA rechargeables.  

The AR-1733 has two bandwidth filters, the PR130 has none, and this at times can allow the AR-1733 to filter out interference better.

SITES:
A. At home, with unavoidable noise, under real world conditions.

Barefoot:

AR-1733: Over an extended period of time I have tested this radio at home. The internal aerial has a good level of directional gain and this allows me to null out pest stations. During daylight hours, I can often log a large number of Tasmanian and Victorian stations. After dark, I can log most states of Australian. I have noticed that the AR-1733 is more sensitive to local noise sources, such as mobile phones. I often need to make sure I leave mine in the other room. I have also noticed that our washing machine causes issues, it took me a while to track down some of the random band noise to this.

PR130: The performance of this is normally 75%-80% of my AR-1733. The biggest issues are that as this has a much smaller internal aerial, it does not pull in signals as well. Where it does perform better is handling overload from local stations, whereas the AR-1733 struggles with stations on either side of my local HPON station, the PR130 will, with careful orientation pull in acceptable signals. The smaller size also allows it to be placed for the best possible signal levels. Of late I have been focusing on logging some South Australian stations and this has produced some good results. I also find it makes a good bed time radio and after dark it really comes to life.

B. Portable, in the field. More or less an ideal site QRM free to check receiver's features. For this test I have chosen Talbot Road Lookout.

Barefoot:

AR-1733: Generally this performed better away from home and at a higher location. The biggest issue was due to the outdoor location, audio quality suffered due to wind and passing traffic noise.

PR130: The performance of this was on par with at home and it didn’t have as much of a performance boast as the AR-1733. I found that the alignment of this with the direction of my target station was critical, as it was slightly closer to my local HPON station, this appeared to desense the PR130 to some extent.

Other Considerations:

FM: Band: Both of these radios were tested at home and at Talbot Road Lookout.

AR-1733: Picked up all major FM Stations I would expect. I also logged a couple of low power stations including LC FM. Overload on adjacent frequencies from a couple of the high power ABC stations was noticed.

PR130: This radio really shines on the FM band and performance was on par with the AR-1733, it did seem to have less issues with the ABC stations not causing as much overloading and audio was good. 

Audio quality: Both radios produce audio with a nice tone and acceptable volume, the PR130 really shines with the use of ear phones and this is mostly how I use it.

Ease of use: The PR130 has less buttons, this makes usage in the dark much easier (less to remember) and the side mounted tuning buttons are easy to find and use as needed. The AR-1733 has a lot more buttons and as these are not backlit, it is easy to hit the wrong button by accident. For day time DXing, the full keypad makes moving between frequencies much easier.



TEAC PR130 V Digitech AR-1733 - Head to Head Testing - December 2020

Thanks Kevin.

Thankfully we have FTTP NBN in this area so we don't need to worry about ADSL and the MTM NBN issues (like others do). I have checked via Google Street View and I have three pole mounted transformers within 150m, I am sort of right in the middle of these.

I have a similar situation in which the utility pole which has power and POTS/xDSL runs in back of my house and does similar. The good thing is that the transformer on the pole was replaced a couple of years ago which took care of some of the noise and arcing due to local salt fog (beach weather!). Still does not clear it all up as my power drop runs diagonal across the yard to the back and middle of the house.

Thanks for the reply. I might go for a walk over the weekend and see what I can find and hear on the band. The last month or so has had really bad weather most weekends so I have been stuck at home more than I would like.

Hi Paul,

If you need a bit of exercise, tune a radio to a dead frequency and go for a walk around your neighbourhood.

You will find dirty/faulty insulators, poor junctions, plasma TV sets and others; all contributing to QRM.

If you take the radio on a tour inside your house, you might surprise yourself with how much QRM some of your household appliances generate.

At my location in Adelaide, QRM is never below S7 and frequently above S9 unless there is a power outage.  When the power fails, I can pull in just about all SA and many Victorian and Tassie stations in the day time but, when the power is on, I simply give up on any DX.  We've just had 3 days of horrendous winds and not even a single flicker on the mains, very disappointing.

Hi Paul,

If you need a bit of exercise, tune a radio to a dead frequency and go for a walk around your neighbourhood.

You will find dirty/faulty insulators, poor junctions, plasma TV sets and others; all contributing to QRM.

If you take the radio on a tour inside your house, you might surprise yourself with how much QRM some of your household appliances generate.

At my location in Adelaide, QRM is never below S7 and frequently above S9 unless there is a power outage.  When the power fails, I can pull in just about all SA and many Victorian and Tassie stations in the day time but, when the power is on, I simply give up on any DX.  We've just had 3 days of horrendous winds and not even a single flicker on the mains, very disappointing.

Re: South Australian DX Loggings - November 2020

Thanks Dan.

I have 7FG on 1161Khz which is 1KW, I will see how I go with nulling it out. I will also check out 963Khz.

Good logging's there. The Adelaide one's seem to come in fairly well here too. I'll have to try logging 5CK & 5MV here too.
Some others you may be able to log may be 5SE on 963Khz, A commercial station at Mt Gambier. Where I am it's a battle for supremacy between that one & 2RG Griffith. Depending on how you orientate the radio. 
The other one to try for is 1161Khz 5PA National from Naracoorte 10k.

Re: AM/MW daytime reception test from Echuca VIC.

Dan Merta
 

That's a good catch. It is an interesting station. It usually comes in here reliably at night. 
And when I was in Sydney in 2011 it boomed in at night as a local strength signal.

Re: New Tecsun PL-398

Hi,
Peter (DXChannel) has extensively tested the Tecsun PL-390 and also PL-398. The three-part unboxing video can be viewed here: PL-398MP unboxing Part 1


In the forums (DX Skywaves) he has always highlighted this Tecsun model -at least for FM recption- but I know he could get more than decent TA MW stations from Africa, where he is now based (Botswana, I reckon!).

¡Buen DX!

South Australian DX Loggings - November 2020

Paul Blundell
 

Over the past few weeks I have been focusing on logging stations from South Australia, these are all between 1000 - 1300 km away. From my attempts so far, just after our local sun set seems to produce the best results.
