Hi Guys,

Interesting this subject comes up on soft mute. I've been working on a blog post about soft mute and just what it is and its technical parameters.

Here's the data on soft mute:

What is soft mute?
 
Soft-mute is a further lowering of the audio level of the received signal when it drops below a prescribed signal-to-noise ratio. It was implemented in consumer grade DSP radios to provide a more "comfortable listening experience" for the casual listener and not the DXer. The idea is to relieve the listener from all that nasty low level "static" and "interference", or as Silicon Labs states: "....to attenuate the audio outputs and minimize audible noise in compromised signal conditions."
 
Soft mute attenuation is available in the Si473x digitally-tuned series of chips as well as the Si483x analog-tuned series of chips. The soft mute feature is triggered by the SNR (signal-to-noise) metric. The SNR value is directly readable by the chip's software when you tune to a station. The SNR threshold for activating soft mute is programmable, as are soft mute attenuation levels, attack/release rates and attenuation slope.
 
The Tecsun PL-380, PL-310, PL-330, and other radios all may set different soft mute values than the chip's default values shown below. Settings for soft mute are initialized during the power up sequence.
 
The 4 soft mute parameters: Rate, Slope, Max Attenuation, Threshold.
 
Rate (default): 278 dB/second (range 1-255, actual figure 278 = setting * 4.35)
Determines how quickly soft mute is applied/released when soft mute is allowed (enabled). 
 
Slope (default): 2 dB (range 1-5 dB per dB of SNR)
The attenuation slope for soft mute application - in dB of attenuation per dB SNR below the soft mute SNR threshold. Translated: how much audio attenuation to applied as the SNR and signal quality decreases. A setting of 2 will lower the audio by 2 dB for each 1 dB reduction of SNR below the starting threshold at which soft mute kicks in. An example: soft mute starts to kick in when the SNR decreases to 10 dB. At 10 dB, there is 0 dB of soft mute. When the SNR decreases to 9 dB, soft mute reduces the audio level by 2 dB. When the SNR decreases to 8 dB, soft mute reduces the audio level by another 2 dB (4 dB total). By the time the SNR hits 2 dB, the soft mute has reduced the audio level to a max of 16 dB. It will go no lower as the max soft mute has been applied. Note that every 6 dB of audio reduction is a halving of the audio voltage level. 12 dB of reduction is then 1/4 of the original audio voltage level. 16 dB (max soft mute) is a reduction of 84.2% (0.158).
 
Max Attenuation (default): 16 dB (range 0-63 dB, max attenuation of soft mute)
If set to 0, soft mute is disabled entirely.
 
Threshold (default): 10 dB (range 0-63 dB, SNR at which soft mute starts to engage). Silabs states, "for a tuned frequency".
 
Note that the Threshold setting is applicable only "for a tuned frequency". I take this to mean that soft mute is dis-engaged totally when not tuned to an exact 9 or 10 KHz channel, which is apparently why the 1 KHz off-tuning hack works.
 
What you're hearing when a signal's SNR lowers below the threshold and the soft mute kicks in is the Slope factor in action. The Slope factor is lowering the audio volume accordingly.
 
Two other interesting parameters effecting tuning and seeking.
 
AM Seek/Tune SNR Threshold.
SNR Threshold which determines if a valid channel has been found during Seek/Tune.
Specified in units of dB in 1 dB steps (0–63). Default threshold is 5 dB.
 
This tells us that when you do a scan, only stations with >5 dB SNR are elegible to be stored.
 
AM Seek/Tune Received Signal Strength Threshold (RSSI).
RSSI Threshold which determines if a valid channel has been found during
Seek/Tune. Specified in units of dBµV in 1 dBµV steps (0–63). Default threshold is
25 dBµV.
 
This tells us that when you do a scan, only stations with >25 dBµV RSSI are eligible to be stored.

Re: Soft mute disable

gordrstaples
 

When I was referring to defeating soft mute, I meant particularly on the AM band, not the SW band.  If you try to tune a station on say AM 760 and then retune to 759 or 761, this gets rid of the soft mute action and the station audio then does not 'pump' with increasing or decreasing signal strength.  The audio level however does drop a bit when retuning +- 1Khz but can be compensated by increasing the volume level.  This technique works well on the Tecsun PL380 and PL390 radios. Note that the soft mute "feature" is not as aggressive on some Tecsun models as on others and also depends on the manufacture date. I have a PL380 from the year 2010 which soft mute is not nearly as aggressive as another which was manufactured in 2016.  😷

AM-BCB and SW bands are handled differently IIRC. My proceedure was for AM-BCB w/10kHz spacing.
I will check SW usiing AM-BCB proceedure on the PL330.

Re: Soft mute disable

Gord Seifert
 


   I have a PL-310et and I do not notice any change when trying these soft mute disable proceedures. But then, I don't notice any soft mute at all on this radio. Turning it off and on does not reinstate soft mute. Is there a way that soft mute could have been locked off? As it is I have no complaints, it is a very good radio. Just trying to understand.

DX TEST TONIGHT! --WNJC 1360 Washington Township, NJ FT-8 Weak Signal Mode -- GREAT CONDITIONS

Les Rayburn
 


Another DX Test from WNJC-1360 late night tonight! We’re getting spoiled with the weekly DX Test. But tonight’s conditions are the best so far. Great opportunity for DX’ers in Europe and on the West Coast to snag WNJC.

Duke Hamann of WNJC has announced another weekly DX Test of WNJC 1360, which will include the FT-8 mode. A first of its kind for a station doing DX Tests on the MW Band. Tonight’s test will be Omnidirectional pattern at 1250 watts. 

Reception reports can be sent to Duke at: kc2dux@duxpond.com

There is also a Facebook Page devoted to the tests:


The test will be in two parts:

WNJC DX TEST PART ONE 0000 EDT-0100 EDT (0400-0500 UTC)

The test begin late tonight starting at midnight on the East Coast of the United States. Late Saturday/Early Sunday, 10/11 at 0000 EDT (0400 UTC) and initially air the same Morse code IDs, jingles, sweep tones, telephone off-hook sounders and other test material.

Conditions are the best they’ve been so far during this prolonged DX Test. should provide a good opportunity for the test to be received in Europe.

WNJC DX TEST PART TWO 0100 EDT-0200 EDT (0500-0600 UTC)


Duke Hamann will be testing for a second hour using the amateur radio mode FT-8, developed by Joe Taylor, K1JT, a Nobel Prize winning astrophysicist.

FT-8 is a “sound card mode” where you simply input audio from your receiver into your computer’s sound card, then use software to process that audio digging out weak signals in the noise. How well does it work? Using the software and the audio from your receiver, you can decode signals that are as much as -24db below the noise.

Many DX’ers have had success using their receivers in the lower-sideband mode (LSB). Since the WNJC transmissions are in AM Mode, they are effectively double-sideband (DSB). Either sideband should work for reception.

Hi Remy

With all due respect, I don't think that procedure works to turn off the soft mute.  I have several Tecsun PL380 radios and tried your technique on them all but didn't notice any improvement at all.  I have found that tuning 1kz up or down off the desired frequency defeats the soft mute, although you need to turn the volume control up a bit to compensate for the volume drop.

Gord

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.

OK, now I see what you mean by soft-mute. But mind you, on the PL380 it
can be deactivated relatively simply. Here's how to go about it:

1/ press VF

1/ tune the receiver to an unused SW frequency.

2/ press and hold VF

4/ when the receiver starts scanning tune down. The background noise
becomes stronger, which shows that this "soft-mute" is no longer active.

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.

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.

Regards,

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.
