Unfortunately it becomes active again when you switch the set off, and
so you have do it all over again when you switch it on again.

It might work with other Tecsun models, I don't know. Maybe you could
try it with the PL-330. It might also improve the action of the synch
detector.

Brilliant. The only thing I've seen that works with the PL-390, the
model I own.

Hi everyone out there,

[...] Minor nitpik is that one should tune 1kHz low for USB as the radio ADDS 1kHz to the receiver. Likewise, the opposite occurs using LSB.
Not necessarily a bad thing. As I see it this might help keep the filter on the actual signal. Too many receivers, when switched to SSB remain with the AM bandwidth and decode only the wanted sideband, which adds some background noise.

Buttons a bit small, but have that nice indent function sadly lacking on the ATS-405. If you don't need the SSB or "Sync", I'd stick with the PL-310/380.
Yes, the PL310/380 receivers are excellent on AM, but as far as the 310 is concerned this applies only to the original version, not the PL-310ET, which is way behind the original version. Unfortunately that one is no longer on the market.

PS: that soft mute question... As far as I know its an Automatic Gain Control function that amplifies the strongest 10db of signal, and reduces lower-powered signals. The problem is that the atmospherics may cause the signal to fade. This causes the soft-mute function to go from a loud signal to a barely audible signal (aka: pumping). Fading normally produces this effect, but soft-mute makes it worse. The SYNC function is supposed to help this by supplying the carrier wave that fades. The problem with THAT is the audio is part of that faded carrier. Many of us here and in the Amateur community are of the opinion that the audio frequencies are NOT affected by the fading, just the carrier. Providing a carrier will recover the audio. Yet another 'can of worms' so to say.

The audio frequencies are necessarily affected by the fading, which is caused by multipath propagation. Two or more signals arrive out of phase which causes a sort of notch that creeps through the bandwidth, just as if you were using a notch filter. Of course this just changes the tone of the audio and does not cause the distorion you get when the notch reaches the carrier itself. That change of tone will be more important if the notch is wide and go almost unnoticed if it is very narrow.

Rémy.


Ultralight Radio DXing Kit - October 2020

Paul Blundell
 

With my focus on Ultralight radio DXing, my radio kit has changed, a couple of radios have been removed and I was finding my previous case was not working very well for me, the quality of the foam was not great.


I was out doing some shopping recently when I called passed my local Bunnings store, here I found this new case for $30, I decided to replace my previous case as I found it was not working as well as I would have liked. My plan being to use my previous case for my work tools and use this new case for my Ultralight radio DXing kit.

I started off at home by removing the foam from the base of the case and then sitting all my radios and other pieces of my DXing kit inside to see how they would all fit best.  
 
I ended up placing my 3" FSL at one end and using a piece of pine to divide this off, to the top of this I have attached a small piece of foam wrap, this goes over the top of my 3" FSL and provides some extra protection to this.
 
On the left hand side, I have both my TEAC PR130 and Digitech AR-1733 in cases, this allows them to be easily removed and carried by themselves if I need to. In here I also have my earphones, spare batteries, log sheets and notebook.

Overall, I am very pleased with how well this case has come out, I am able to carry and store multiple radios, log sheets, pens, notes, spare batteries and ear phones, everything I need for portable sessions. It is also small enough to fit in my backpack. For $30 it provides a great level of protection. 

While this case was designed for ultralight DXing the same ideas could be used for amateur radio, radio scanning or any other radio storage need.

Over the years I've had bad luck with the Ni-MH batteries. Some radios just don't like them, and the batteries themselves are as fragile as glass. My tub of 60 alkaline AA's cost $20, or about 67c for the two needed in the R9012 or R911 in the house.

Best of listening with your choices

Re: Current "best" UL DXing Radio

Thanks for the detailed reply.

That is some amazing battery life, I use some 2000mAh recharbales which are sold at our local supermarket, at $5.60 for 4 AA or AAA's, it is amazing how long these last, even if I replace them once a year, I am still miles in front.

I have settled on the Teac PR130 and Digitech AR-1733, I might look at adding to this in the future.

1.) In the meantime, my PL-330 arrived this afternoon. Set up and running without incident. AM/SW/FM, and USB/LSB function checked... all as advertised. Noted that the 1kHz offset on AM removes the soft-mute. SSB with the 0.01kHz (10Hz) tuning increments does function on AM-BCB. Minor nitpik is that one should tune 1kHz low for USB as the radio ADDS 1kHz to the receiver. Likewise, the opposite occurs using LSB.

Buttons a bit small, but have that nice indent function sadly lacking on the ATS-405. If you don't need the SSB or "Sync", I'd stick with the PL-310/380.

2.) I don't know the why for this, but since I bought the R9012 radio, I've noticed an increase in battery life. I believe this is a combination of using the Tecsun A200 passive loop, and an improvement of my standard-use Rayovac AA alkalines. Would you belive 550+ hours continuous?

Using the loop improved life from just over 400 hrs average to 500 hours. And I think the new tub of batterries 'high energy' with date code of early 2029 improved the time more. The most recent pair of AA's could operate the radio down to 0.94V (1.88V total). All of my previous batteries would quit at 1.05V (total 2.10V).  This last pair of new batteries went 608 hours continuous.

So in closing there are some new tricks here that may influence a decision. For about US$45 one gets either a PL310/380 or a R9012 + A200 loop. For AM-BCB this looks like a coinflip, but the PL-310 really excels at SW and FM. And the R9012/loop gets one emergency radio type life from a pair of AA's. If one needs SSB theres the Tecsun PL-365 or this PL330 in the US$70-80 range.

Over at the World of Radio group Andy Reid is reporting that 1350 CJNL in B.C. has gone silent. Also 1040 CJMS has had its CRTC problems, and is on temp. authority. It has been ordered off-air a few times this year. You might want to try for this one while you can.

Here are some updates/corrections to the list.

530    CHLO    Not really Greek programming as such.  Mostly south Asian (Hindi, Punjabi) with just a bit of other ethnic programming on weekends or evenings.

960    CKNT    Mississauga, ON     0.7kW day     0.7kW night    Slogan is “Sauga 960 AM”

1220    CFAJ     St. Catharines, ON     Power unknown but probably 1kW at this time.  Came on earlier this year and has been in "testing" mode ever since. 
Format is "oldies" pop.  Signal seems a bit stronger at my location now so maybe they've bumped up the power.  I emailed them for more info but got no reply.

1280    CJRU    Toronto, ON     0.099kW day    0.099kW night     Ryerson University radio.

1350    CIRF    Brampton, ON     Power unknown but perhaps 1kW    ID is "R. Humsafar" with south Asian programming.  New station this year.

Test will be at the daytime power of 10,000 watts, but we are not yet certain about which antenna pattern may be available for the test. 
Todd is attempting to arrange a change to the ND pattern, but may be limited to the night pattern which favors the North and South, with nulls towards E-W.

Test will consist of voice announcements, Morse Code ID’s, sweep tones, off-hook telephone sounders, etc. The station has a small staff, so they have asked the CPC Committee to handle reception reports and verifications. Verifications will be by e-mail only. A specially designed QSL card in Adobe PDF format will be sent to successful reports. 

The CPC prefers audio recordings in .MP3 or .WAV format. These should be e-mailed to: les@...

Re: Current "best" UL DXing Radio

Gregory Mosher
 

About the PL330  and SYNC – I’d wait for the reviews before pulling the trigger.  The PL-990x export version was just released, it’s had solid reviews except for SYNC.  I recently bought a China market Tecsun H-501 and frankly, it’s a nice radio – solid performer, however SYNC sucks – in my mind, not useable. However, SSB on the H-501 is solid – works well.  All three of these radios had same intro date and similar availability date – suggesting they were probably developed together.  Also, reasonable to expect that if the SYNC implementation on 2 of the 3 new models are not stellar, that’s what you’re going to get with the 3rd.   Also – why would they have a poor SYNC implementation on their two flagship models and a good implementation of it on the least expensive of the three? 

I’m comparing the SYNC ability on the H-501 to that on the Eton E-1 – no comparison.  SSB capability though is similar between the two. 

BTW – I’ve had a Radiwow R-108 for just over a month now – solid little performer, not bad for ~ $50 (Amazon).   I’d rate it better than my early production Tecsun PL310.  Sharp nulls possible.  Probably as good as the non SSB Skywave – the R108 is purported to be a copy?

Regards,
Gregory


Re: Current "best" UL DXing Radio

Paul S. in CT
 

Sorry for the double-post... a few things came to mind.

1.) Analog ULDX Radio... IMHO Tecsun R-9012. US$20 and batteries (2AA) last over 400 hours continuous. I've done it many, many times (The R-911 also does this, but SW less good). Makes for an emergency radio.

PL-330...
2.) I am reading that the SYNC detection does not work well on the pre-export models (Chinese manual). But USB/LSB with 10Hz is the bee's knees.

3.) The rechargable BL-5c battery might only last 30-60 hours, get a spare and an external charger (eBay has them resonable $)

Re: Current "best" UL DXing Radio

As far as the PL-330, I have one on order. Should arrive in the USA at my door by mid Nov. Review at swling.com. Pix and specs at ebay.

Without SSB... Tecsun PL-310
With SSB... Grundig G6/Skywave (both can overload, needs a DX switch)

I've owned both the PL-310 and the G6. Not as good as larger radios, (Superradio 2 or Grundig G5/Degen 1103) but portability for travel is great. The PL-310 can be offset 1kHz to stop the soft mute effect.
