Tecsun PL-330:  The Powerful Mini With One Serious Design Issue

by Dan Robinson

As SWLing Post readers know, I have a huge radio collection – including premium receivers and portables, now nearly 100 in all.

So, these days I am hesitant to add too many, but I continue to take interest in what companies such as Tecsun and Sangean are doing in the way of stuffing the latest chip technology and capabilities into portables radios.

The last receivers I reviewed included the Tecsun PL-990x, which has developed quite an enthusiastic following since its consumer version was released in 2020, and the Tecsun S-8800.

Out for some time now is the Tecsun PL-330.  By now there are many reviews of it on You Tube and elsewhere.

It’s become a familiar observation for many of us – if this were still the 1960’s and 1970’s – even into the 1980’s, which could be considered the golden days of shortwave and we had receiver technology like this, well what a joy that would have been.

When I traveled around the world both before and after college, and professionally for Voice of America in the 1980s and 1990s, wow what a good time I could have had with today’s portables!

Some world band portables radios back then were superb performers.  The Grundig Satellit series 500/700/600/650 come to mind – but these were not exactly what I would call small portables.

Paging through Passport to Worldband Radio from 1990 (wow, that’s 30 years ago!) you see others such as the SONY SW-1, Panasonic RF-B65, and of course, the SONY ICF-2001D/2010 which introduced killer synchronous tuning technology in the 1980s and remains popular today decades after it first appeared.

Also available were the SONY ICF-SW55 and later in competition with the 2010, the SONY ICF-SW77.  Today, I have four SW-55s and two SW-77s and still use them regularly.

Tabletop receivers back in the good ol’ days offered multiple selectivity positions.  One of those was the Lowe HF-225 (and later Europa version) along with the HF-250, Kenwood R-5000 and R-2000, ICOM IC-R71A, and Yaesu FRG-8800 among many others.

But as far as smaller portables go, features such as synchronous detection and multiple selectivity were still pretty limited, and a number of receivers didn’t offer selectable synchronous as was eventually offered on the Drake R8B and later production of the SW-8.

The RF-B65 by Panasonic – which today remains sought after for its amazing sensitivity – was hobbled by having a single selectivity position.  Same with SONY’s SW-1 and SW-100, and 7600GR, though SONY’s PRO-80 had two bandwidths.

Indeed, it wasn’t until Eton brought out the E-1, with its three bandwidths combined with Passband Tuning (though no notch filter) that a portable finally reflected capabilities of some of the better tabletop radios (though lacking a notch filter).

The Grundig Satellit 800 was close in competition with the E-1 (though the earlier Sat 600/650 series also had multiple bandwidths) but was bulky.

Fast forward to 2021 – credit due to Tecsun and more recently to Sangean with its 909X2, for some years now we have enjoyed Asia-originated portables with multiple selectivity and synchronous mode, though sync implementation on some has left much to be desired.

Which is where the PL-330 comes in.  When I look at the 330, I am reminded of one of the now ancient SONY portables, the ICF-4920 which was a super small slide-rule receiver that nevertheless was quite sensitive.

Like the 4920, which you could easily slip in a pocket, the PL-330 is a perfect travel portable.  Only the Belka-DX SDR and still wonderful SONY SW-100 compete in terms of performance and size.

The 330 is basically a PL-990x in miniature:  smaller speaker obviously, shorter antenna, no bluetooth capability or card slot.  But as many people who frequent the Facebook groups have observed, pretty much anything the 990x can do, so can the 330.

This radio has ETM/ATS tuning, synchronous detection, multiple bandwidths in AM, SSB and MW, FM mono-stereo speaker control, alarm/timer functions, external antenna jack, display light, and other features.

Tecsun decided to go with a BL-5C battery here – the same with the new PL-368.  I think this is unfortunate, since it requires one to obtain a number of those flat batteries if you want to travel and not have to re-charge.  On the other hand, this is not a crippling design decision.

What is an unfortunate design problem, in my view, involves the simple question of tuning the receiver.

The main and fine tuning knobs on the right side of the PL-330 are embedded into the cabinet just far enough as to make easy rapid finger tuning of the radio nearly impossible.

In fact, in my testing it’s impossible to thumb tune the radio more than 10 kHz at a time.  The same applies to using the lower knob which controls volume.  When in FM mode, this issue make tuning just as frustrating almost forcing one to use rapid scan mode.

Another puzzler:  Tecsun limited bandwidths in AM SW to three, while in SSB you have 5 bandwidth options.  In AM mode, you have a 9 kHz bandwidth, another puzzling choice.  Longwave too is limited to 3 bandwidths.

But overall, none of these problems really knock the PL-330 down very far.  This is one mini powerhouse of a radio, one that makes you think “wow, if I had just had this back in 1967 or 1973 or 1982.

Some additional thoughts.  My particular PL-330 was supplied by Anon-co but is a pre-production version and so does not have the latest firmware.  Thankfully, I have not experienced the issue of SSB tuning running in reverse as others have.

NOTE:  As most users know by now, but some newer users may not, you cannot charge one of these radios – whether Tecsun or Sangean – using the mini-USB port and use them at the same time. . . there is just too much noise introduced from the charging process.

This little mentioned feature:  just as the Tecsun 909x has a re-calibration function, so does the PL-330.  Tecsun itself initially declined to acknowledge this, but finally confirmed through Anon-co.

The procedure: Switch to LSB/USB.  If the station is not zero beat, hit STEP button once and then quickly again to move the flashing display down arrow so it’s above the far right digit.  Then fine tune the station for zero beat.  Hold LSB or USB in for a couple of seconds.  The LCD blinks.  You then have zero beat – but be sure to repeat the process for LSB and USB.

I should mention that just like on the 990x, the re-calibration process doesn’t mean the receiver is then zeroed up and down the shortwave bands.  You will likely have to repeat the process from, say 25 meters, to 19 meters, to 49 meters, etc.

I have come to enjoy using the PL-330 here in my house, though like other portables in my collection I need to position it in one particular corner of my home away from incoming cable TV lines.

Belka-DX and Tecsun PL-330

The PL-330 and the Belka DX are currently king of the pile when it comes to my smaller travel portables.

I fully expect there will be no further receiver development by Tecsun after the PL-330/990x/H-510 radios – but that company will certainly have left us with some great receivers as the days of shortwave approach an end.

Tecsun PL-330 tip: Using the telescopic antenna for the LW & MW bands

Many thanks to SWLing Post contributor, Mad Radio DXer, who writes:

Hi,

I want to let you & your readers know of a Tecsun PL-330 trick that I saw mentioned in the comments section of your blog some time ago which does not seem to have a lot of awareness. This is for using the telescopic antenna for the LW & MW bands, & it works for the 3305 version of the PL-330 which I understand is the export version. The original comment I saw said this also works for the Chinese version of the PL-330, before firmware 3305.
It is very easy to do & instructions are the following…

1. Turn on the radio.
2. Select either the MW or LW band.
3. Press the number 3 key down for a few seconds, until the display shows “CH-S”.
This means the MW & LW bands can now be received with the telescopic antenna.
4. To use the ferrite bar again, press the number 3 key until “CH-A” appears on screen.

I also did a YouTube video showing this trick in action…

This reminds me of the trick used for the Degen DE1103 PLL version which allows reception of the telescopic antenna for the MW band. However, in my opinion this is much easier to use on the PL-330 than the DE1103 PLL which could be very fiddly. Also this trick is most effective on the LW band, as I find Chinese portables are usually very weak on this part of the band which is good news for LW DXers. I hope you & everyone reading find this trick very useful & that it works.

Thank you so much for the excellent tip!

Michael’s impressions of the Tecsun PL-330

Many thanks to SWLing Post contributor, Michael Sharpe, who writes:

Hi Thomas,

Here are some personal observations after playing with the Tecsun PL-330 for a couple weeks, maybe an hour or two a day. I made a point of picking up the 310ET , the CCrane Skywave SSB and the G6 Aviator at the same time for some comparisons.

These comments are in no particular order.

The PL330 is very lightweight compared to the other three. This could be perceived in two ways.

A. The case seems less sturdy than it could be, it creaks and ‘gives’ a little when operating some of the controls that require ‘squeezing’ to activate a button. I would prefer a more solid feel.

B. The radio is very light which is a plus for travelling with hand luggage. You’ll like that 🙂

The backlight can be set to permanently ‘on’, I really like this. None of the other radios do this when on battery power only. I don’t consider any radio ‘portable’ if it is tethered to a power supply. It would be nice if the buttons lit up but let’s stay real here !

Tuning: I am not crazy about the detented operation of the tuning knob, but I recognise that this is a requirement on the lower cost portables that use digital tuning. However…the PL-330 scores highly because the detent clicking is soft and silent. When compared to the Skywave SSB, there is a world of difference. For me, a clicking knob eliminates the option to tune around the ham bands when my wife is trying to sleep. I did email CCrane to ask if a solution may be suggested, but the response was negative. The G6 Aviator wins hands down in this area, but apples to pears !

Memory Tuning: I really like the options here, easy to use and the time selective ETM+ is genius. I also like the easy ‘delete all memories’ option which enables a fresh start at any time.

Audio: It’s not a PL-880 but its Ok for a small portable and the bandwidth option is a big plus. I’m no expert here because I do a fair proportion of my listening with a mono single side earpiece at night.

AM: Seems to work fine. Pulls in everything I normally listen to and seems sensitive and stable enough.

FM: Seems to work fine. Pulls in everything I normally listen to (not much!) and seems sensitive enough. Brilliant that it will suppress stereo unless the headphone socket is used.

SW: I spend a lot of time here and it seems good enough. I did compare reception with the Belka DX and had nothing to complain about. I have learned that keyboard tuning to a frequency near the frequency of interest and then final tuning with the annoying detent knob is the way to go. Also, memory tuning is easy and makes the detent truly functional.

SSB: This my main area of interest as I love to tune around the ham bands, especially when travelling with no access to real ham gear. The fine tuning at 10 Hz with suppressed soft muting is a real winner. It would be nice if soft mute could be disabled completely but I understand this is limitation of the DSP hardware.

Calibration seems easy too with just a long press on the USB button when the audio is zero beat (note the calibration option is for the AM band but utilizes the USB or LSB to zero beat and set). I don’t do this any more, after all, what’s the point when tuning around to listen 🙂 Just twiddle the knob until it sounds good and Bob’s your uncle. I think the ‘Step’ button should replace the ‘Sync’ button and not be shared with the sunken ‘lock’ button. Too squeezy.

SYNC: Don’t bother. I tried it several times, not so much any more. Waste of a perfectly good button. (See SSB above.)

Battery: I actually like the battery choice. I get that AA’s or AAA’s are a good choice for emergency use because of availability but in an emergency you would probably have your phone with you, and some means of charging it. Just have an appropriate cable or adapter in the bag and you are good to go. My current phone uses the usb micro, as does the PL330 so I may be a little biased at this time.

Antenna: For portable use, the existing antennas work fine. The SW input jack works and the ability to switch the AM signal source between the internal ferrite and the external jack is a nice touch if you want to experiment.

I cut the wrist strap off, not sure what benefit this offers but they all have them. I must be missing something ?

A rear stand would be nice but it stands on its base reasonably well.

So….for around $60, it’s a no-brainer in my book.

Hope this helps. I’m no expert when it comes to deviation ratios, 3rd order intercepts, microvolt sensitivity etc. etc. but these are my impressions from a guy who just likes to play with radios.

Best wishes

Michael (N9YZM)

Thank you for sharing your impressions of the Tecsun PL-330, Michael! I’ve also been testing the PL-330 and find that it is a great value for $60–certainly a low-cost alternative to the C.Crane CC Skywave SSB (although I much prefer the build quality of the Skywave). My family life has been so busy this past month, I’ve had little dedicated time to do comparisons, but it appears to me that the PL-330 is a solid performer.

Thanks again for sharing your assessment, Michael!

The export version of the Tecsun PL-330 has landed

Tuesday evening, I picked up a package from Anon-Co with the new export version of the Tecsun PL-330 inside. Anon-Co sent this unit to me for evaluation at no charge to me. Anon-Co will start shipping the PL-330 next week and the price will be $59.99.

By request, I took a few photos of the PL-330 as I unpacked it. This should give you an idea about how the radio is packed and what is included in the Anon-Co package:

The Anon-Co PL-330 package includes:

  • Tecsun PL-330 receiver
  • an English owner’s manual
  • a brown synthetic velveteen carry pouch
  • MicroUSB charging cable
  • earphones

My first thought? It looks like a mini PL-990!

The PL-330 is powered by one BL-5C battery pack. To meet shipping regulations, the BL-5C is not pre-installed–you’ll need to do that yourself.

Note that the PL-330 lacks a fold-out back stand. That is unfortunate

On the air

Unfortunately, I’ve had no proper time to evaluate the PL-330 (comparisons) yet as this is an incredibly busy week for me.

I did, however, listen to the PL-330 as I worked outside all day Wednesday. Sadly, there was a lot of news to follow here in the States that day.

I was able to receive all of my benchmark local and regional AM and FM stations with no problem. For day-to-day broadcast listening, it seems to be a solid portable.

It’s still early days, but I think the PL-330 may be one of the best portables for FM I’ve tested in a while. On Wednesday, I tuned to WFAE in Charlotte a number of times throughout the day and the PL-330’s lock on the station was rock-solid. WFAE’s transmitter is just over one hundred miles from my home, so this is typically a tough catch if I’m inside my home or my car, etc.

The real test? I can also receive WFAE with the PL-330 in my kitchen window. Again, only a small number of portables can reliably grab WFAE’s signal from that spot. Indeed, the PL-330 almost receives WFAE as if were a local station.

While this is far from a laboratory test, it is certainly a real-world test for this radio enthusiast.

I’ve yet to dive into the shortwaves, although I’m incredibly curious how well the sync lock might work. I’m keeping expectations low–after all, this is a $60 radio. The price point is quite good for sporting upper and lower sideband reception, let alone synchronous detection.

Tecsun PL-330 fine tuning bug

Many thanks to SWLing Post contributor, Pawel Kita, who writes:

Good morning Thomas.

I bought a Tecsun PL-330 firmware 3303.

Do you remember when I once reported a bug in one of the versions of the
Tecsun PL-880 radio? This error was later named as “fine tuning TECSUN reversed bug”

The same error occurs in the following Tecsun radios: PL-365 and PL-330
firmware version 3303.

Thank you for the tip, Pawel. That is an odd and slightly obscure bug that Tecsun obviously has yet to address.
