Many thanks to SWLing Post contributor, Tom Kamp (PA/DF5JL), who shares the following brief report and video:
Today (September 21, 2022) around 2015 UT strong signal on 5006 kHz (CF) from JG2XA beacon from Japan (0.2 kW) near Den Helder, in North-Holland, The Netherlands.
JG2XA transmits continuously at 200 W on 5006 kHz and 8006 kHz. The type of radio signal is H2A (amplitude modulation with coded tones in the single sideband).
Received with the Tecsun PL-368 and the built-in telescopic antenna! The dBm display of the unit is very inaccurate (in USB), yet S5-S7 should be rated appropriately. Top signal, top RX ?

That’s quite a catch for the PL-365. Thanks for sharing this, Tom!

Hi Thomas
Wondering if you’ve heard of similar experiences: since receipt on 4th November I have been using the new gadget (Firmware 3684E) almost daily until yesterday when the ferrite bar antenna suddenly did not work any longer. I became aware of the fault when I put the rod into the antenna jack noticing that the field strength reading drops to zero so that the radio becomes deaf!
I somehow suspect that the fault lies in the socket. As a matter of fact, I had/have the same problem with the old 365 with its green design ferrite rod. What seems rather odd to me however, is the fact that if I plug in an external active antenna (Wellbrook, Bonito, RF Systems DX-one) both units work properly, furthermore, the 368 ferrite bar miraculously works on the 365 whereas the 365 rod doesn’t on either model!? So, with the best of will, I cannot blame the socket for sure – or is it that the rod-plugs are too thin to give proper contact – I don’t know.
Since I was unable to find any pertaining findings in the net, I do hope that you may have further information from your worldwide reader feedbacks!?
SWLing Post readers: If you have experienced this same issue or can diagnose what might be happening with Ulrich’s PL-365 and PL-368, please comment!

Tecsun PL-368: Large Receiver Features In Smaller Vertical Handheld
by Dan Robinson
It was back in 2020 that the first photos surfaced online of the PL-368 – posted on Facebook by someone attending the electronics fair in Shanghai, China.
Photos showed the successor to the PL-360/365 receivers – and also the PL-990, successor to the PL-880, as well as the new king of the hill for Tecsun, the larger dual speaker H-501.
Things looked promising, and it was pretty exciting. Tecsun designers upgraded the PL-365 which had become a favorite of preppers and SWLs, but which was hobbled by the lack of a keypad, to the re-named PL-368.
The PL-365 and PL-360 before it were plagued by the problem of being overly sensitive to the touch – when holding the radio, reception was fine, but remove your hand and signal levels plummeted. Usually, a full hand grip was necessary to obtain full sensitivity and any variation in grip reduced sensitivity – this was noticed mostly in shortwave mode.
Previous 360/365 models were known for the included small rotatable ferrite
AM amplified antenna which performed miracles in nulling mediumwave stations – for those who still like to listen to the AM band. The 368 also comes with this additional ferrite antenna.
And the 365/360 (which were and still are sold by CountyComm as the GP-5) used AA batteries, making it very easy to find replacements anywhere the radio is being used in the field. Tecsun changed that on the 368.
After the photos appeared, I contacted Benny Zhao, who had posted them on one of the Facebook groups and asked if he could send me a sample of the PL-368. He obliged and a 368 was sent on its way.
The radio was sent without the BL-5C flat lithium battery which was prohibited in postal shipments. It took a long, long time (3 months, apparently the package was sent by snail mail) but it finally arrived here and I have been putting it through some tests.
The PL-368 that I received has the notation “2020.12 VER 1” so it’s clearly a first version from 2020 production.
Like the models before it is a great, handy, portable to grab if you’re going on a trip. It is lighter than the older 360/365s. The change from three AA batteries to the flat BL-5C explains some of that. There is a heft to the older models that the 368 doesn’t have. I am not sure about differences in thickness of the 368 cabinet. Perhaps we will find out more from Tecsun (see notes below regarding issue of tapping the front of the 368 cabinet).
The 368 retains the two multi function adjustment wheels on the right side, one for Volume, the other for Tuning. These are also used for time and bandwidth control.
Tecsun PL-368 (left) and PL-365 (right)
On the 360/365 radios, I never found the tuning wheel approach to be particularly efficient since it was limited to a certain number of kHz per turn, either 5 or 1 kHz depending how fast you turned.
On the 368 it appears you can obtain up to 40 kHz from a single turn of the wheel, while on the 360/365 that was limited to 15 to 20 kHz depending on the speed you were turning.
Tecsun PL-368 (left) and PL-365 (right)
The antenna on the 368 is thinner, but 8 inches longer than the 360/365 models, and in the box you will find the included and very effective rotatable ferrite antenna for mediumwave that inserts in a jack on the top.
On the 368 the volume wheel has detents, whereas on the 360/365 the wheel had smooth turning.
We have gone from 14 buttons on the old PL-360/365 models to 28 buttons on the PL-368, including addition of the keypad.
UPGRADES
Tecsun has upgraded the 368 in line with improvements seen in the PL-990x and H-501 receivers. There are now adjustable bandwidths – a particularly useful tool. These bandwidths also operate in SSB, something that the new Sangean ATS-909×2 doesn’t offer. Bandwidths are: LW/MW 2.5, 3.5, 9.0 SW: 2.5, 3.5, and 5.0 SSB: 0.5, 1.2, 2.2, 3.0 and 4.0 kHz
Also in the 368 is now synchronous detection, a feature left off Sangean’s 909×2. And you get the same intelligent tuning features seen in the 909x/501x models as well as the previous PL-880.
Tecsun added a control that enables activation of the light – this is located on the same button as the Step control which adjusts the tuning steps.
The 368 display now has the ability to tune in 10 Hz increments, an overdue upgrade from the 360/365 models.
Charging of the BL-5C battery can be carried out by connecting a DC 5V/0.5A adapter to the micro-USB port on the side of the radio. The English manual notes that when charging, the charging time is displayed at the top right corner of the display while the “Charge” indicator flashes.
Adjustments for 9/10 kHz mediumwave, Longwave, and FM frequency range can be found on the 1, 2 and 3 keys.
The manual notes that in addition to the internal ferrite bar antenna, the external supplied MW/LW ferrite antenna can be connected to the antenna socket on top and rotated to obtain optimum reception.
Addition of the keypad makes the PL-368 far more useful than its predecessors for instantaneous frequency access. This was the major drawback of the 360 and 365 receivers. This can’t be emphasized enough.
This is a day versus night difference and vastly improves the attractiveness of the 368 over previous models.
There are 850 memory presets, 100 for FM/LW, 150 for MW, 300 for SW, and 100 each for SSB and SYNC.
ATS tuning, like the 990x and 501 receivers enables ATS within all meter bands by holding the [<] or within a selected meter band by holding the [>]. The manual also notes the ability to auto scan all stored stations within a frequency band or mode (SYNC/SSB) staying on each station for about 5 seconds before resuming.
The 368 has what Tecsun now calls Enhanced Tuning Mode (ETM+) – as explained in the manual, this allows auto tune and storing of FM, LW, MW and SW stations into ETM memory. Unlike ATS, scanned stations will not be stored into regular memory (VM) – in this way, when in a different city or country, ETM+ can be used to auto search new stations without overwriting any previously stored stations.
FM De-emphasis Time Constant – as explained in the manual, while receiving FM broadcasts, long pressing [4] will adjust the de-emphasis setting for Europe, Australia, Japan (and most other locations), or for Americas and South Korea.
Add Seconds to the Clock – with the device powered off, press and hold [8] to add seconds to the clock.
Sleep Timer – as with its predecessors, the 368 has a Sleep Timer, with an indicator on the LCD display.
Alarm – and like earlier models, there is also an Alarm function, which allows the radio to turn on at a preset time. It’s possible to select a specific frequency to be used with the Alarm.
RE-CALIBRATION – I have not been able to determine yet if the 368 has a re-calibration function as can be found on the PL-330, 909x, and H-501.
PROBLEMS
Let’s get one headline out to start: The 368, as with the 909x and H-501 all have the useful Synchronous Detection mode. However, SYNC continues to be hobbled, showing distortion and loss of lock.
As I have mentioned in reviews of the 330, 990x, and 501x any successful use of SYNC requires a delicate dance involving careful selection of various bandwidths while in SYNC mode and fine tuning.
The 368 manual contains 3 pages of explanation of SYNC noting that it can “eliminate distortion generated in the IF filter due to local fading, slight offset, modulation overshoot, as well as inter-channel interference and cross-talk modulation, and can also reduce noise interference.”
The problem with all of the Tecsun DSP chip receivers after the PL-880, which had a hidden SYNC feature that was the worst of the bunch, is the extent to which SYNC still suffers from distortion and loss of lock that renders the feature far less useful than it could be.
Ideally, one would want SYNC to match the capability achieved in such older receivers as SONY’s ICF-2010, SW-100S, SW-07, 7600GR. You’re not going to get that with Tecsun receivers.
Like its predecessors, the 368 is still sensitive to touch. I noticed this immediately on the old 360/365 receivers, especially when using the radios
at the beach. If I was recording a station on shortwave, and left for a few minutes, I would return to find that sensitivity had dropped because the radio was not still being held in the hand, which rendered the recording useless.
I am continuing testing of the 368 to try to determine if this issue has been reduced to any extent and will update this review with any further findings. This sensitivity issue is not specific to the 368 – it can be seen on other older and newer receivers.
Many older portables (the SONY ICF-SW55 comes to mind) were constructed with robust cabinets that were less sensitive to touch. Touching the whip antennas on some older receivers improved reception, while on others touching the whip antenna actually reduced sensitivity.
URGENT ATTENTION FOR TECSUN: My initial testing of this particular China market unit of the PL-368 – again, it is marked as December 2020 Version 1 production – identified an additional issue.
When in SSB modes or SYNC, tapping on any area of the keypad and LCD display produces a warbling/distortion effect in the audio. One can only surmise that this is attributable to insufficiently robust construction of the PCB board underneath.
(Video shows problem created when physically tapping front of PL-368 cabinet.)
This is NOT a problem seen with my PL-365 when it is in SSB mode.
I hope that Tecsun gives this the attention it needs and corrects the problem in future production runs.
SUMMARY
Were it not for the major problems detailed above, the PL-368 would be an automatic must-buy receiver in my book.
Addition of the keypad is a night and day improvement and when combined with additional features such as multi-bandwidth options and the still-to-be-perfected synchronous detection, the 368 would be a killer portable.
But as with the PL-330, 909x and 501x the problem with SYNC mode is still a major drawback on a feature that is supposed to lift Tecsun receivers out of the pack of portables that are on the market in 2021.
One can live with the issue of cabinet sensitivity – but the additional issue I identified where there is instability introduced when tapping on the front panel/keypad/LCD is a QC problem that simply must be addressed by Tecsun.
But as I have said in reviews of other Tecsun receivers, let’s back up a bit. Imagine if we had had portable receivers with the capabilities that these have, back in the 1960’s or 1970’s.
It’s one of the great ironies of the radio listening hobby, that in 2021 any company is willing to continue producing receivers of this caliber as use of shortwave by major broadcasters continues to decline.
The obvious other killer feature to include in portables such as this would be to somehow integrate DRM into them. However, I have a feeling that will never happen

I “watch” the Anon-Co new additions page for changes and this morning I received an update that the PL-365 has been added. I think they only used to stock the non-usb Pl-360 version.
Thanks for the tip, Gareth! The PL-365 is a very sensitive portable receiver and one of the least expensive with a proper SSB mode. I’m happy Anon-Co has added them to their inventory.
Many thanks to SWLing Post contributor, Julien, who writes with the following question:
First, thanks for your site !
I have a question about PL-365. It seems auto-scan works only in the range of 2,245-21,950 kHz. The ranges from 1,711-2,245 and 21,950-29,999 can only be scan manually.
Do you know the reason for this? Or a trick to auto-scan the other two ranges?
I do not know the reason for the auto scan limits, but imagine it could be a limitation of the SiLabs DSP chip inside–although this is merely a guess. My hope is that someone in our community can verify or perhaps help if they know of a work-around. Please comment!

Tecsun PL-365 Review
by Charlie Wardale
I have had this receiver for over 6 months now, and whilst not using it every day, I have used it enough to have an informed opinion of it’s pro’s and con’s.
Overview
A quick description of the receiver for those who have not heard of it.
The receiver is of an unusual design, more like a hand-held transceiver, measuring 53(W) X 159(H) X 26(D) mm. It naturally fits in the hand, with the thumb resting easily on the thumb-wheel tuning. The buttons on the front are for a number of alarm and display functions, SSB selection, and ETM, along with band selection and up/down keys. The inclusion of SSB makes this quite a unique radio, and certainly interesting to use when out and about.
It is supplied with ear buds, faux leather carrying case, the plug-in MW bar, and instruction booklet. A manual is also available to download.
As can be seen from the picture, the receiver sports a telescopic antenna for FM/SW, and a unique plug-in MW ferrite rod antenna, which is rotatable in its socket.
Band coverage is as follows:
FM 87~108 MHz
MW 522~1620
SW 1711~29999 kHz
Long Wave is also available and on mine was factory set to be included, but if not, it can be made available by the menu options.
Like many of Tecsun’s latest receivers, the PL-365 includes the ETM function, which stands for Easy Tuning Mode. With this, you select the band (MW,FM,SW), press ETM, and it loads into a local memory, all the stations that it detects. These do not over-ride any of the main memory that may have been already used to store stations. It is specific ‘ETM’ memory. Once the detection process is completed, the tuning wheel is then used to select each of the stations detected. This is an extremely useful feature on this receiver, as it doesn’t have keypad entry for frequencies. And band scanning using the thumb wheel in 5 Khz steps can get tedious! Of course, ETM will have to be repeated a number of times during an extended listening period as stations come and go.
Initial Listening Tests
My first port of call on starting the listening tests was FM, to judge how it received the local and national broadcasters, and to see how stereo broadcasts are received. Incidentally, I changed the supplied ear buds for some in-ear types which I find stay in place better. All national broadcasters (BBC) and local radio stations (BBC and independent) were detected well. Received audio on the built in speaker is pleasant, but as can imagined from such a small speaker, not of great range. However, stereo broadcasts from BBC Radio 3 (classical music) and Classic FM, sounded excellent using the ear buds. At night time, some further afield stations are detected, so the FM sensitivity is good.
When I conducted these initial tests, it was evening so I decided to give the MW band a whirl as well. I fitted the MW bar antenna into it’s socket atop the receiver, selected MW and hit the ETM button. After a couple of minutes, the detection process stopped and a great number of stations had been detected. Going through them, not only were there the local (and not so local) UK MW stations, but some from much further afield such as Bretagne 5, SBC in Riyadh, and RNE Radio 5 in Madrid. By turning the ferrite antenna, it was possible to peak these stations nicely.
So now to SW. As can be seen, SW coverage is full range from 1711 – 29999, excellent for a receiver of this price range. For this initial test, listening was carried out in the early evening, in the garden, during the summer, so the higher bands were where most of the action was. Following a similar pattern to the FM and MW test, the telescopic whip was extended and the ETM button pressed. On stopping detection, a total of 65 stations were noted. One or two of these, it later proved, were images, but for the most part they were all receivable signals. The treshold for detection is quite low, so some stations are barely audible under the noise, a testament to the sensitivity of the 365. All the major stations were received well, such as VOA on 15580, Saudia Arabia on a number of frequencies, CRI of course, over numerous frequencies. And in between, stations such as CNR1 (China National Radio), the regional Chinese service, and R Australia on 12065, BBC from Singapore.
After this, I did some listening on the 20 and 40m ham bands. To do this is slightly tricky, as it entails coming out of ETM mode by pressing the VF/VM button. This puts the radio into frequency mode and the thumb wheel is then used to get to the correct frequency. The USB/LSB button is then pressed and once a station is found, press the BFO button. The tuning thumb then becomes a BFO fine tune, and the amateur radio station can be tuned in accurately. It is tricky to start with but you do get used to it and amateur stations can be tuned in well. I received a number of European stations on 40m and European/Asian ones on 20m. So again, sensitivity is good, even though this is just using the whip antenna.
Long Term Listening Impressions
Over the months between those initial tests and now, I have done a number of hours listening using this radio, on both the MW and SW bands. I especially like it if I am out for a walk in the country near us as its handy to carry in the pocket. One Sunday I listened to the whole hour of a VOA broadcast on 15580, whilst wandering along the Lincolnshire foot paths. And it is also a nice radio to do a bit of casual listening from the armchair of an evening, when the TV is on but of no interest. This way I have enjoyed many a broadcast from VOA, RRI and the BBC using the ear buds. It’s also nice to tune into the Celtic music of Bretagne 5 during the evening on MW as a change from the fair on BBC Radio 2 or 3.
Conclusion
Would I recommend this radio? Yes I would, whole heartedly. For what it is designed to do, it does very well. Could it be better? Of course. A keypad would be nice, an external antenna port would be great and so on. But it was designed to be a general coverage receiver, in a small, hand-held package, and for that it receives top marks.
Many thanks for your review, Charlie! I agree with you that the PL-365 is ideal, in terms of form factor, for radio listening while on long walks and hikes! It is certainly an excellent portable.

Comparing the CountyComm GP5-SSB and Tecsun PL-365
County Comm GP-5/SSB and Tecsun PL-365: a couple of years ago, I obtained a GP-5/SSB from Universal and have enjoyed using the radio. It’s extremely sensitive, often bringing in signals in the middle of my house here in Maryland, and is fun to use, provided the auto-tune is done to insert frequencies so you don’t have to use the thumb wheel too much.
I have often thought that the next logical upgrade for this radio would be to add a small keypad to allow direct frequency selection, but perhaps that is not in the cards. The County Comm is basically the Tecsun PL-365, but the actual Tecsun version has not been available for the most part from major sellers, even from Anon-Co in Hong Kong, or Universal. You can still find some PL-365’s from certain Ebay sellers. Last year I obtained two from a Hong Kong seller. Both were NIB, and arrived within about a week or so of purchase.
What I noticed immediately is that the PL-365 has a different kind of exterior surface, more rubberized than the County Comm. I was curious about any differences in performance that might be obvious. Recently, I took both outside for a very basic comparison — not scientific by any means, but I think it shows something that I have noticed.
Both share the characteristics of extreme directionality, and sensitivity to touch — sensitivity increases markedly when they are hand-held, decreases noticeably when they are left standing on their own, or angled. I have noticed this when using them at the beach. If I am recording a station, and leave the radio alone for a few minutes, I return to find reception degraded quite a bit, because they were not being held.
In my very basic comparison, I had both receivers next to each other on a backyard table, both antennas fully extended, full batteries on both. While on some frequencies, at least initially, it seems little difference can be heard, on others there is what seems to be greater clarity and signal separation on the PL-365.
I noticed this from the start on 13.710 where the County Comm appears to be noisier than the PL-365, and on the portions later in the video when both are tuned to 11.820 (de-tuned to 11,818) Saudi Arabia, and to 11.945 khz.
Apologies for the length of the video. It’s hard to draw any conclusions based on this comparison, and I intend to do some additional tests with both my PL-365s and will report back on any findings, but I thought this would be of interest to those of you out there with these fine little radios.
Thank you for this review and comparison, Dan. I’m often asked if there is any difference in performance to justify the extra costs typically associated with the PL-365. I can now share this video and your review–potential owners to draw their own conclusions.
