Many thanks to SWLing Post contributor, Don (W7SSB), who notes that Josh (KI6NAZ) at Ham Radio Crash Course has just posted his final TX-500 video. If you’ve been considering the TX-500, it’s very much worth your time:
Josh is actually sending me this very same TX-500 for review in The Spectrum Monitor magazine and here on the SWLing Post.
Please comment if you have any questions and I’ll do my best to answer them while I have the unit here at SWLing Post HQ.
Many thanks to SWLing Post contributor, George Joachim, who shares the following review of the Tecsun PL-990.
AS George points out, the PL-990 in the following review is not the “export” model Anon-Co will eventually offer for sale later this year. It might be nearly identical in every respect, but at time of posting Tecsun is addressing some final firmware updates the the “export” version prior to starting a full first production run. As we learn more about the various versions of the PL-990 in the wild–compare serial numbers, etc.– we will eventually sort out any nuances between versions.
George purchased this PL-990 on AliExpress and I am incredibly grateful to read his review of this model:
by George Joachim
The Tecsun PL 990 is one of the three new radios offered by Tecsun and according to the news from the company these may be the last developed.
The other two radios are the Tecsun H-501 and the PL-330. The H-501 is the largest with dual speakers and the PL-990 is of a similar size to the PL-880, PL-680, PL-660 and PL-600. The PL-330 is the smallest and is similar to the PL-310ET and PL-380.
The Tecsun PL-990 is a medium sized portable multi-function radio. It has the following features:
The radio is a refinement of the PL-880 with styling similar to the PL-680. It is matte black with a hint of grey, finished in a quality plastic case and it is ergonomic with a good weight and feel, just like the PL-880.
This is my fourth portable radio of this size. I had owned the analogue Sony ICF-7601 back in the day and then the PL-660 and PL-880. The Sony was destroyed by me doing naughty electronic experiments and both the PL-660 and PL-880 were gifted to my family members.
Having no such radio, I considered the purchase of a new PL-880. I had contacted Ms Anna from the Anon Co. in HK and she was very helpful and also mentioned that Tecsun is developing a couple of new radios, but these are not yet available. This got me interested in the PL-990 and the H-501. I had also considered the H-501, because I liked the fact that it has two speaker sets, however the radio did seem a big bulky for my needs. I have a few desktop radios, but I needed something to be on my lap or by the bedside. Usually I fiddle with these portable radios lying on my chest until I find something nice to listen to then let it play on auto sleep until it puts me to sleep. I am sure some of you guys do this too. I imagine the H-501 would be a bit big for this.
After reading articles on the SWLing Post and despite the warnings about Pilot run versions and Chinese versions, I decided to risk a purchase from AliExpress. This has been my one and only purchase on AliExpress so far.
My radio was supplied by a company called Li Jia Shops in AliExpress. It cost a steep US$400 and US$157 DHL shipping. Totally expensive and risky in my opinion, but I am known to be reckless with my online purchases.? Besides, I wanted a new toy!
As this was my first purchase from AliExpress, I was a bit apprehensive, as I mainly use eBay. Also buying electronic items from China is a bit risky. One may end up not getting the item, or getting it after some significant delay. As you all know, electronic items exported from China is the largest electronics export operation in the world, so there is congestion in logistics and Covid-19 also adds to that. Selecting DHL to ship the item was very expensive, but I believe necessary. Waiting for an expensive electronic device for two months is a painful experience, at least from my perspective. Using DHL took a mere 12 days. The main delay originated from the shippers. They give the shipment information to DHL well in advance, but they do not actually take the item to DHL unless it suits their facilitators who they assign. The shipment shows as shipped and DHL status is ‘shipment information received’, but in reality the item is still with the shippers. Once it does actually get to DHL, then it is quite fast. Usually the shippers are located in the Shenzhen area and DHL is in Hong Kong. AliExpress will not release the payment unless the buyer confirms receipt of the item as described, so there is some safety for the buyer.
Overall, I was satisfied with the purchase and shipping process. But it was expensive and it was risky. It would be better to approach Anon Co in HK for your purchases rather than AliExpress and Bangood, but ultimately it is the buyer’s decision. For the English Export Version you must wait a bit I think.
This aspect is a bit confusing. From what I understood, and I could well be wrong, the versions are as follows:
Pilot run: this has the buttons as TIME DISPLAY and ALARM (this is also slightly cheaper on AliExpress and Banggood)
Chinese version: TIME TIMER A and TIMER B, but with Chinese manuals (what I have acquired)
Export Version: TIME TIMER A and TIMER B but with English manuals. (there may be further changes / improvements, as these units are still not available)
I am not sure about the firmware. My unit is presumably a later Chinese Version. And everything works properly as per the Firmware. The serial number of my unit indicates a possible manufacture date of July 2020, although this could be wrong.
The review will be based on the different functions of the radio.
In the UAE we are blessed with several English language FM radio stations with good music and limited advertisements. Each station caters to particular tastes, such as 90s music, modern and classic hits. Reproduction was crisp and in full bodied stereo. The speaker is powerful and not unlike the speaker of the PL-880.
I do not usually listen to AM or MW. However, the radio does a good job receiving these stations with a deep sound and minimal crackling.
Shortwave is still out there folks, although its variety and abundance is greatly reduced. I do receive quite a few broadcasts using the telescopic antenna. Activity is concentrated around the 16m band, the 31m band and the 49m band, although occasional broadcasts can also be found in the 22m, 19m and 41m bands. The SYNC function holds on to weak broadcasts and makes them intelligible. I am sure that the Radio would do a commendable job if one could use a time machine to take it back to the SW hay-days of the 80s and 90s. I wonder if they have any time machines up for sale in AliExpress? 🙂
Right out of the box I was able to fine tune into 14,182.10 kHz on the USB and hear HAMS ‘doing their thang’. It was excellent and far better than what similar attempts resulted in my previous Tecsun radios. I do think that Tecsun has improved the SSB reception with this receiver. I am not a very capable SSB chaser, but if there is something SSB out there, the PL-990 should able to pull it in. One needs to know where and when to tune and luck also plays a role.
Yes it is there, but no, I have never heard anything in there using the PL-990 and all my previous radios. I do wonder if submarines transmit in the LW band? I don’t know.
A lot of listeners are not interested in MP3 listening, but I am. Especially with SW being so sparse nowadays. MP3 was a feature missed from previous Tecsun radios. I enjoy compiling a list of favourite tracks and listening to them, while engaged in a barbecue or in car maintenance or cleaning. I am also a train modeler and like to listen to MP3s while running my trains. Tecsun has even supplied a Sandisk micro SD card of 16GB with various Chinese and international tracks, which I think was nice of them.
There is no Bluetooth button, but by pressing the RADIO/MP3 button an indication will come on the display as BT. The radio can then be conveniently paired with a mobile phone to transfer the audio from a you tube clip or similar to the radio, although I wouldn’t see the need for that. I am not sure if files can be transferred to the radio this way, I believe the function is only for audio playback.
Much like the PL-880, the radio comes superbly packaged. The cardboard box functions as a glossy display of the radio and its features. Inside there are foam holders and there is a sturdy grey plastic toolbox case. In the toolbox case there is the radio, within a nylon bag inside its light brown faux leather pouch. The radio as well as the pouch have a carrying strap. In the toolbox there is a black foam case that contains:
The radio uses one Li-Ion type 18650 3.7V battery. The included type is a blue generic unbranded type, I would have preferred a Tecsun-branded battery. I have a couple of vape equipment batteries –Golisi S30, which I believe are superior to the unbranded battery. (No, I am not a Vaper).
The latest Tecsun offering is a great conclusion to their series of multi-function portable radios. It offers some advantages over the PL-880, such as:
Apart from the above I don’t see a compelling reason to acquire the radio unless, SSB or MP3 is important for you. Or like me, you just must have the latest.
Style: 90%
FM: 100%
SW: 90% SYNC available
SSB: 95%
MW: 85%
LW: 80%
Battery Life: 70% for the provided battery 8/10 for externally sourced batteries
Display: 70% (the display is good, but it hasn’t really changed from previous displays)
Buttons: 85% Sturdy and precise, no wobbly buttons here.
Dials: 90% hard and precise with excellent indentations
Ports: 90% strong a tight female ports with protection plugs
Packaging: 95% anything you could wish for.
Documentation: 100% for Chinese speakers
Antenna: 60% normal telescopic antenna, should be a bit more shiny IMO.
Stability: 70% Stands well and has the rear bracket as the PL-880, however, would be easy to snap if pushed.
Sensitivity: 95% if it is there it will receive it and improve the signal over listening time.
Overall Review Score:
85.3%
Final thoughts:
Go get one, if you must, but better wait for the full export version.

Many thanks, George, for sharing your review of the PL-990!
So far, the PL-990 sounds like it has iterative improvements over the PL-880 which is, I suppose, what I would expect. The PL-880 is a great portable, so I believe even minor performance upgrades–especially in terms of synchronous detection–could be very beneficial to some SWLs. And thanks for taking the deep-dive and grabbing one of the models on AliExpress! It’ll be interesting to compare notes once the “export” PL-990 is released.
Many thanks to SWLing Post contributors, Paul and John (KC8RZM), who share the following press release from Icom:
Icom Incorporated (Headquarters: Hirano, Osaka, Japan/President: Masataka Harima) releases the ID-52A/E*, VHF/UHF dual band digital transceiver that supports D-STAR (Digital Smart Technologies for Amateur Radio).
* ID-52A is the USA version, ID-52E is the European version
The ID-52A/E is equipped with a color display. The display size is increased to 2.3 inches (1.7 inches for the ID-51A/E), and a transflective display is used to achieve excellent visibility, even in bright sunlight. The transceiver also supports Bluetooth® communication as standard. Wirelessly connect to Android™ devices with ST-4001A/ST-4001I Picture Utility Software and RS-MS1A Remote Control Software installed, the optional VS-3 Bluetooth® headset is also available, for hands-free operation.
And the following features are enhanced from the previous ID-51A/E models. Simultaneous reception in V/V, U/U, V/U as well as DV/DV. Air band reception is expanded from VHF to UHF (225 to 374.995 MHz). The new model can be charged via micro USB connector. Audio output is significantly increased from 400 mW to 750 mW. The latest function of D-STAR enables you to send, receive and view saved photos on an installed microSD card using only the ID-52A/E.
In addition to the above, the ID-52A/E has a variety of attractive features such as the DR function with easy set-up, built-in GPS receiver, micro SD card slot, IPX7* waterproof construction, and Terminal/Access Point modes. The ID-52A/E is a product that leads the amateur radio digital communications with enriched features that satisfy any users, from beginners to even heavy users who want to fully enjoy D-STAR.
I’ve just learned via Universal Radio that the new Icom IC-705 has been F.C.C. approved and is scheduled to start shipping in the US “early Fall 2020.”
Consensus from other sources in the industry is that Icom would like to start shipping the IC-705 by the end of September but have not committed to a specific date. I assume they’re being cautious due to Covid-19 logistics challenges.
I’ve no firm report on availability from the UK, Europe, or other countries as of yet, but I would have to assume they’re on a similar timeline.
Also, there is still no word on a firm US price. UPDATE: Steve (K9SWX) notes that Ham Radio Outlet has posted a retail price of $1,299.95 US. Gigaparts has also listed the price as $1299.95.
At time of posting, I couldn’t find other US retailers who have confirmed a price, however, you can expect that the price will consistently be $1,299.95 US. Manufacturers like Icom often cap any retailer price adjustments and (sometimes) extra perks when new products are introduced.
ML&S has a pre-order price listed at £1299.95 ( £1083.29 EXC. VAT). The price in Japan is roughly 124,800 yen.
I have pre-ordered an IC-705 for review even knowing Icom early adopters pay a premium. I’m incredibly curious if the IC-705 will hold up well in the field and especially how it might compare with my other benchmark QRP transceivers.
We’ll continue to post updates as they become available. Bookmark the tag: IC-705

While doing the daily eBay and AliExpress strolling for new and cool radio stuff, this showed up:
RX888 ADC SDR Receiver radio1.8GHz 16bit direct sampling HF UHF VHF HDSDR
Like the DragonFly RX-666 you posted about recently, it’s based on IK1XPV Oscar’s BBRF103 works. Both share a hefty metal case.
I really like this seller of RX888 on eBay. The person provided quite a bit of technical details. The seller is also up-front about the current challenges regarding thermal issues, software stability and bandwidth available above 32MHz.
(How many manufacturers let you know in advance the negatives? I like this guy!).
The bandwidth limit above 32MHz is a curious one. Apparently, coverage above VHF and UHF coverage relies on Rafael Micro’s R820T2 tuner chip (also used on RTL dongles and AirSpy R2 and AirSpy Mini). However, R820T2 can only push a slice of 8 to 10MHz of the spectrum into RX888’s ADC. So, FM broadcast DXers, be warned. You may need to use a downconverter that brings the 88-108MHz to 8-28MHz. Perseus SDR uses this approach.
Another interesting tidbit. As we know, TaoBao is a huge marketplace, but their sellers focus exclusively on the China market (very few also deliver to South East Asia). There are LOTS of cool, never-seen-before products on TaoBao that don’t have visibility to us here in the Western hemisphere. The RX888 was one of them, I recalled seeing it about a month ago and thinking “Hey, this is so cool, why are they not selling it on AliExpress yet?”
Thank you so much for the tip! I agree with you: it’s refreshing to read not only a thorough eBay description but also frank comments from the seller.
I must admit, the receiver world is going through a dynamic change and its champion is the SDR. It’s hard to keep up with the innovations and technology is pushing limits I could not have imagined even a decade ago.
I’m looking forward to checking out these super wideband SDRs like the RX-666, RX-888, and the ELAD FDM-S3.

Last night I came across a new SDR receiver from China called ‘RX-666’. On paper its specs are interesting: 16bit ADC, max sample rate 32MHz (in theory one could sample the whole LW+MW+SW bands at the same time), USB 3 interface, and tunable from 1kHz to 1.8GHz.
Its design seems to be a “derivative” of Oscar Steila’s (IK1XPV) BBRF103 SDR – see this post from Oscar – it looks like they upgraded the ADC, made use of a better voltage regulator, and moved to a 4-layer PCB (the original was a 2-layer PCB).
Unfortunately (for Linux people like me) they only have proprietary drivers running on Windows.
Besides the AliExpress store, I saw it is also available on eBay – the AliExpress vendor has two versions, a cheaper one with a ‘standard crystal’, and a more expensive one with an ‘upgraded crystal’; I messaged them earlier to find out what is the difference between the two, but I haven’t heard back yet.
I thought some of those readers of the Post who are interested in capturing large parts of the radio spectrum to decode later might want to look into this SDR receiver.
Thanks for the info on this SDR, Franco. I was not familiar with it. A 16 bit wide band SDR with a 32 MHz working bandwidth is most impressive–I’m sure FM DXers will be following this closely. I’m glad they’re using a USB 3.0 port but am very curious if it can even handle the amount of data should a user initiate a really wide spectrum recording. Perhaps recordings have capped bandwidths?
As a side note, someone should tell the manufacturer that their model number “RX-666” is…well…a culturally sensitive number!
Post Readers: Please comment if you’re familiar with this SDR.
We’re starting to get a little more info about the recently posted Silphase R1 SDR receiver. At this point, the radio isn’t in production and is obviously only in a prototype stage so there are a lot of question marks–including if it’ll ever come to fruition. The pandemic is obviously not an ideal time to launch and produce a new high-end radio. I, for one, certainly hope they do!
Many thanks to SWLing Post contributor, Mark Hirst asked Silphase about R1 external antenna support and power options. A Silphase representative replied:
“We are constantly redesigning the rear panel receiver Silphase R1, so we
can say for sure that there are 4 connectors – antenna F-type connector,
12.6 V power/charging, RJ-45 and USB”
And thanks to SWLing Post contributor, Paul, who received the following info from Silphase:
