In 2019, shortly after Icom announced the Icom IC-705, I speculated that this rig might be a contender for “Holy Grail” status.

I must admit…the more I use this radio, the more I love it. It is a proper Swiss Army Knife of a radio. Even though I’ve owned and operated it for a few months, I still haven’t explored all that it can do, and I keep finding features I love.

Case in point

Yesterday, I upgraded my IC-705’s firmware. Unlike other devices I’ve been evaluating recently, IC-705 firmware updates aren’t fixing numerous bugs and issues, rather they’re adding more functionality.

After completing the upgrade, I hooked the ‘705 up to my main antenna and worked a few Parks On The Air (POTA) stations off of the supplied battery pack (instead of a power supply). While I worked on other projects in the shack, I checked the POTA spots and work a few stations with a whopping 5 watts of output power.

After a couple hours on the air (mostly listening), the internal battery pack still had a good 60-70% capacity.

At one point, I tried a little daytime mediumwave DXing and cruised past 630 kHz which some of you might already know is the home of one of my favorite hometown radio stations, WAIZ.

From my home, WAIZ is a tough catch, so it was weak, but I could hear it.

This reminded me that I had made a recording of WAIZ with the IC-705 when in my hometown earlier this month.

Normally, I pull the MicroSD card out of the IC-705–which almost requires needle nose pliers and is one of my few complaints about this rig–and view the files on my PC or MacBook, but I was curious if perhaps the IC-705 software had a built-in file display.

Of course it does!

Simply press the MENU button, then the RECORD button on the touch screen, and you’ll see the following selections:

Press “Play Files” and you then see a list of folders organized by date:

Click on a folder and you’ll see a list of recordings made that day:

Here’s the genius bit for those of us who like to archive broadcast recordings…the IC-705 embeds the following meta data:

Date of recording
Start time of recording
Recording length
Frequency
Mode

These are some of the most important pieces of information I use to index my audio recordings and the IC-705 does this automatically. In fact, if you allow the IC-705 to gather its time information from the internal GPS, the time stamp will be incredibly accurate.

The only thing I add to the file name after export is the broadcaster name/station callsign.

If that wasn’t enough, if you touch one of the recording files, the IC-705 will open it in an audio player:

The built-in player displays the meta data, and even includes a number of controls like fast-forward, rewind, skip to next or previous file. and pause.

I’m sure this is the same audio player found in the IC-7300, IC-R8600 and other late-model Icom SDR rigs. But in a portable battery powered transceiver? This is a genius feature.

As I type this post I’m listening to the audio from the WAIZ file shown above. I can imagine when I’m able to travel again (post-pandemic), how useful this will for one-bag air travel.

(If you’d like to listen to WAIZ, check out these ‘705 recordings.)

Not only is the IC-705 a QRP transceiver and wideband multi-mode general coverage receiver, but it’s a recorder and audio player with a built-in front-facing speaker. I can set this transceiver at my hotel bedside and listen to recordings I made in the field earlier that day or week.

Keep in mind that the IC-705 is an expensive radio–certainly one of the most pricey QRP radios ever produced at $1,300 US (at time of posting although I’m sure we’ll start seeing lower pricing this year). But if you’re an SWL and ham, you’ll find the IC-705 is the most versatile portable transceiver on the market. If you’re an SWL only, you can disable the transmit on the IC-705 and essentially have a portable battery-powered SDR receiver with built-in audio recording and playback with color touch screen spectrum and waterfall display.

Despite the price, this is Holy Grail territory in my book.

Xiegu GSOC after latest v1.3 firmware update

16 Replies

Yesterday, I cleared my radio bench and performed a few firmware updates that were recently published for the Xiegu GSOC Controller and Xiegu G90.

Upgrading the Xiegu GSOC to the latest firmware version requires also upgrading the Xiegu G90 to take full advantage of the GSOC fixes.

I downloaded the G90 firmware, driver and upgrade tool, then read through the upgrade manual. The process is pretty straight-forward, but the G90 transceiver actually has two units to upgrade: the control head and the transceiver body. I successfully completed both with no errors from the firmware tool.

Next, I downloaded the 300MB+ GSOC upgrade which is essentially an entire Linux operating system. I flashed it to a 16GB MicroSD card, inserted it in the GSOC and after turning it on it extracted and upgraded its OS. It’s an easy upgrade, but requires a MicroSD card and download time (especially if you’re like me and have a crummy rural internet connection). 🙂

GSOC v1.3

After I completed the upgrade, I connected the GSOC control head to the Xiegu G90 once again and turned it on.

The GSOC still takes a good 30 seconds to start up because it’s essentially loading a Linux OS.

Keep in mind there was one fix in particular I was looking forward to checking out: the CW latency issue.

CW latency

As I mentioned in my initial GSOC post, and also in the post after the first GSOC firmware update, the GSOC had been exhibiting sidetone latency that interfered with my ability to correctly send words and letters. In fact, it really made it impossible to send accurate code at speeds north of 11 WPM or so. Xiegu engineers tried to fix this after the first GSOC update, but it was still present. I suspected the GSOC CPU simply wasn’t fast enough to produce sidetone audio as the G90 body fed it a steady stream of dits and dashes. So far, my GSOC evaluation has pretty much been on hold because I’m unable to use CW mode.

I’m happy to note that Xiegu has now fixed the CW latency issue, but there’s a small caveat. I’ll explain…

In SSB, FM, or AM mode, for example, the GSOC produces audio via its internal speaker. This is also how it used to produce CW sidetone audio.

After the v1.3 firmware update, when you use CW mode, the audio will be produced by the G90 body. Not an elegant solution, but this does eliminate CW sidetone latency because the GSOC controller is effectively eliminated from the audio chain.

I connected the GSCO/G90 to a dummy load and tested CW which seemed to work fine. Then I hopped on the air and worked POTA activators in Ohio, Maryland and Indiana with no problem because I was essentially only using the G90 body (hence the same experience I had in my G90 review).

Honestly? This might not bother some ops, but it is a bit weird to use the GSOC on AM and SSB then switch to CW mode since the speaker audio moves from the GSOC to the G90 body. (If using headphones, I suppose you’ll have to unplug from the GSOC and plug into the G90.)

When I’ve had the GSOC in the shack, I’ve placed the control head on my table (which is the main operating position) then placed the G90 body about 2 feet away behind one of my PC monitors. With this setup, the audio jump to the G90 body is very noticeable.

This GSOC and G90 are both on loan from Radioddity, but if I owned the GSOC, I believe I’d connect an external speaker to the G90 to bring the audio closer.

It’s worth noting that If the “Modem” function is turned on in CW mode, the audio will be played via the GSOC (not the G90 body).

Noise on the spectrum display

Although it wasn’t noted in the firmware release notes, I had hoped they might have adjusted the IQ feed to help eliminate some ever-present noises on the spectrum display (which cannot be heard in the audio).

After I performed the update, the GSOC spectrum display seems to be somewhat “deaf.”

At least, I’m not able to see signals as I did moments before the upgrade. I can hear signals as I tune through the bands–and they sound fine–but I can’t see anything corresponding appropriately on the spectrum display or waterfall. I tried adjusting the default spectrum gain values but this doesn’t seem to help. I’ll try replacing out the IQ cable, but again I doubt this will have an effect because I’m sure it’s associated with the update.

If I tune to the broadcast bands, I can see strong AM signals in the spectrum, but it seems weaker SSB and CW signals are lost.

I haven’t seen other GSOC owners report this yet, so must assume it’s an issue with my particular unit and possibly a glitch from the firmware updates? I will contact the manufacturer and see if this can be sorted out.

Summary

The v1.3 firmware update also added a Bluetooth serial port, tweaked AGC algorithms, and added the ability to perform a full reset from the GSOC system menu. There are still some missing anticipated features like direct audio recording to the MicroSD card.

If I’m being perfectly honest, though, the GSOC still feels like a product in Alpha or Beta testing–not one in production. The CW sidetone issue would have been discovered if Xiegu had even one Beta tester attempt a few CW contacts prior to production. Spectrum display noise would have also been found. In addition, most promised features should have been on the unit from day one and some–like the notch filter–should have functioned properly. The whole unit feels rushed and not yet ready for prime time.

I personally much prefer using the Xiegu G90 as-is, without the GSOC controller. It’s not an Icom IC-7300 or even a Yaesu FT-891 for that matter, but it’s a very budget-friendly, full-featured field radio that sets a benchmark for its $425 US price. While I’m not a huge fan of the G90’s audio, it’s perfectly fine for field use and normal operation.

I’m undecided if I’ll continue reviewing the GSOC at this point–I may simply send it back to Radioddity who–very much to their credit–has embraced my criticisms of this unit. At present, the GSOC and G90 are living in their shipping boxes until I pull them out to perform upgrades, test them, then put them back in the boxes. Not how it should be. When I review new gear, I’m usually eager to put it in full service in my shack and in the field. Frankly, I just feel like the GSCO and G90 take up too much space and are in the way of radios I prefer using.

Are you a Xiegu GSOC owner? What are your thoughts? Please comment.

ABR Industries and the importance of quality cable and connectors

23 Replies

Two radio accessories I often forget to mention in my posts and reviews are cable and connectors. When a cable functions well, it’s taken for granted and easily overlooked.

You’ll hear me say that a radio is only as good as its antenna and while that’s true, the important link in the system is your antenna cable and connectors. If you have a fabulous antenna and a benchmark radio, but you connect the two with substandard cables, it will create unnecessary losses and even shorts if you’re not careful.

But let’s be honest: it’s easy to cheap out on cables.

When I first started using tabletop receivers and transceivers in my youth, I had a tight budget. When I would go to a local hamfest where I’d find excellent prices on cable assemblies from those accessory retailers who sell a little bit of everything. You know…the tables with everything from $10 multimeters to $5 blinking lights–? I’d find their prices for cable assemblies too attractive and would grab them.

No more.

Back when I owned my original Yaesu FT-817, I used one of these cables on Field Day and blew my finals due to a small short ono a connector end (if memory serves, braiding was touching the conductor). From that point forward, I decided I’d invest in quality cables.

ABR Industries

At the Hamvention in 2010, I found ABR Industries’ table. The only thing they had on display were cable assemblies and a handful of cable accessories. I picked one cable up and inspected it–I could tell it was good quality. Although I know how to make my own cable assemblies (with PL-259s, at least) I appreciate professionally-built assemblies.

I spoke with the representative that day and learned about their company and how they go about making standard and custom cable assemblies in the USA for the consumer, commercial, and government markets.

Although the price was at least double what I would have paid at one of the discount retailers, I never looked back.

From that point forward, I’ve only purchased ABR cables typically at Hamvention, Universal Radio, or even directly from ABR’s website (when I ordered custom assemblies).

The quality of ABR cables is second to none. I have never had one fail at home or (especially) in the field.

For my QRP POTA activations, I started investing in ABR316 and ABR100 BNC to BNC assemblies. I’m especially fond of the ABR316 assemblies (above) because they’re so resistant to memory when I coil them.

You pay for what you get

I suppose this is on my mind because I’m about to do an assessment and make another ABR order so that my new field radio kits have their own dedicated cable assemblies with correct ends (so I’m also not forced to use BNC or PL adapters for matching).

I’m also replacing some of my 3 foot cable assemblies with SMA connectors to PL-259 for my bank of SDRs. This is a part of achieving one of my goals for 2021. I’ll know then that each receiver will have a quality link to my antenna splitter and antenna.

My point here is don’t skimp on your cable, adapters, or cable assemblies.

If you have the skill to build your own, buy quality components and take your time building them.

If you prefer purchasing pre-made cable assemblies, talk with your local ham radio retailer, or seek out cable assembly houses like ABR Industries. I’d avoid purchasing cheap cables you may find on eBay or Amazon.com, for example. That’s not to say that there aren’t quality discount assemblies out there, I just prefer buying from a company that takes pride in their work and stands behind the quality.

ABR Industries isn’t a sponsor of the SWLing Post (although I’d love to add them!)–I’m just a long-time customer who is happy to plug their products. I can recommend them without reservation.

[Update: In August 2023, we did become an affiliate of ABR Industries. Purchasing with our links supports the SWLing Post at no cost to you.]

I’ve also bought numerous long cable runs, wire, DC cable, ladder line, paracord, and sealant from The Wireman. I also highly recommend them.

ABR isn’t the only quality cable assembly house–there are many others throughout the world. Who do you recommend? Please leave a comment and links to your picks!

New CC WiFi-3: C.Crane offers discount to CC WiFi customers after demise of Reciva aggregator

23 Replies

Many thanks to SWLing Post contributor, Ron, who notes the following announcement on C.Crane’s website:

We were happy to be one of first companies to offer ad-free Internet radio because it allowed anyone to listen to the world without a fee. Fifteen years ago, Ben, the founder of Reciva, had a small staff to create the software and volunteers around the world to help manage the station streams. We are sorry, but Reciva’s software will soon not work anymore. The software would need to be recreated from scratch. Even If this was done, it would not be possible for the existing radios to be compatible with this new type of software. This is the same way Apple and Microsoft might release a new operating system that is not compatible with older hardware.

We are working on a new radio called the CC WiFi-3. We will be testing the first pilot run of the new CC WiFi-3 in January with the first delivery by April if all goes reasonably well. There are still no ads or graphics to annoy you and nobody tracks your habits for advertising offers. It looks almost the same as the previous CC WiFi but has been upgraded in several ways:

It uses a new 3rd party stream provider called Skytune.

You can add your own streams (URLs) yourself so you are somewhat protected if the service fails for any reason.

It is a little easier to use and it has a good built-in equalizer available.

This radio comes with a 2 year limited warranty.

Anyone can add a valid stream to Skytune. This makes the platform very different from smart speakers that do track your habits and make recurring income. There is no recurring income for C. Crane just like with Reciva and the CC WiFi. The only income is the initial hardware purchase which includes the use of Skytune’s technology embedded on a chip.

If you feel comfortable going forward please read our offer.

This is a one-time offer from C. Crane. This offer will end June 1, 2021.

If you have purchased a CC WiFi and it is under the 1 year limited warranty, contact us for the available options.

If you have purchased a CC WiFi and it is no longer under warranty, the CC WiFi-3 is available for half price – $60.00 USD plus shipping. You must fill out the form (click here) and include a picture of your serial number(s). Instructions are included on the form for how to locate your serial number. If you need help with this, please contact us. You will be contacted once we receive our shipment to get payment information and to confirm your address.

The CC WiFi-3 comes with the risk of losing connection to Skytune’s server if they were to shut down in the future. As we have previously documented in our catalog and on the web: C. Crane has no control over content or the stream provider for Internet radios and cannot be responsible for Internet radio programs or availability.

We think the CC WiFi-3 is a remarkable radio for listening to a clear signal from your favorite station and for discovering new stations. You can go to Skytune.com, click on the “Radio” header to be sure they carry your favorite station or host.

Note: Saving your own list of streaming stations for use takes some computer knowledge. Many of your big streamers block or change the URL daily so you cannot save it. As usual, you have C. Crane’s US Based customer service to help you with any questions about the operation of the CC WiFi-3.

A number of us have been frustrated discovering that the Reciva aggregator, which is the backbone for so many WiFi radios, will shut down by the end of April 2021. While I’m sure many of us are now leery of investing in a new WiFi radio, I love how 1.) C.Crane is offering a 50% discount to existing customers and 2.) are being up-front about the risks of WiFi radios relying on aggregator services.

I’ve been using the Skytune service on my Ocean Digital radio and have been very pleased. I’m pleased to hear the new CC WiFi-3 has an option to manually load Internet radio streams if needed.

Thanks, Ron, for sharing this tip!
