Holy Wow!!!
Okay this thing gets 5 full stars based on premise alone! And before buying, please read the entire post (you'll need it!)
This is exactly what the ham radio hobby needs -- an affordable UHF/VHF HT that has HF and shortwave receive capabilities. So new Technicians can at least listen to what they're missing out on in the world of HF while they study for their General ticket. No lie, it's radios like this that will become the new entry radio of choice for hams on a budget.
With that out of the way, I'll dive into the radio and how it works:
Standard VHF/UHF transmit and receive. The rubber ducky (stock UHF/VHF antenna) is absolutely exceptional. I can clearly hit my favorite repeater 37 miles away (from my kitchen!) with full quieting. It keeps the repeater open, I've gotten good signal reports, and receive sensitivity is really good (set squelch to 1). I'm not going to spend all day here going into commercial FM, NOAA, and air traffic control bands but I will say it receives all three better than any HT I've ever had. Now it will receive 1.25 meters (224 MHz), but sadly will not transmit on that band. But I rarely use that band, so I'll gladly accept the trade-off.
Where I should dock this review one full star is the documentation, or lack thereof. But it is Radioddity, and I'm sure at some point they will improve the manual. There's zero/zilch/nada when it comes to operating on HF with this thing. So I'll go into what I can in hopes the next person has a good starting point.
The bottom button on the left side of the unit (underneath the PTT button) is what toggles on/off HF receive. You have your choice of two antennas, basically the red one is LF/MF and the green one is MF/HF. That being said, the radio itself divides the spectrum up into LW, MW and SW modes. The manual and specs will show you how they categorize those frequencies. For the sake of example, I'll throw on the green "Donut SW Antenna", set the physical H/L switch on the left of the antenna to "high", set the radio "Work Band" setting to SW, and tune the radio to 14.300 MHz if I want to listen to the Maritime Net on 20 meters. If I want to listen to commercial AM broadcasts (500 kHz to 1.5 MHz) I just pop on the red donut AM antenna, Switch the Work Band to MW, and punch in my favorite AM sports news station and boom! I'm in business. Spectrum range is 500 kHz to 30 MHz, so you're getting pretty much everything out there, not just the ham bands.
The HF menu structure has a whopping 5-6 items. #0 is Modulation (FM/AM/CW/LSB/USB) -- #1 is AM Mem Cannel -- #2 is Work Band (LW, MW, SW) -- #3 is Frequency Step -- #4 is LNA (more later on that). Easiest HF menu navigation I've seen yet. Now there is a Bandwidth setting, but it only comes up in the menu when you're in SW mode.
Now as for the donut antennas... They work pretty much like how you'd think they'd work. The little red one is great for local AM commercial broadcasts and won't disappoint you. I'm listening to sports radio inside my home (quite well!) as I write this.
But I have to be honest here, if you're wanting to tune into long distance DX shortwave stations, or you're wanting to listen in on HF SSB conversations (ham operators), these antennas will leave a lot to be desired. They're basically non-functional on a bad propagation day (ie: solar flare), and only pull in strong stations on a good propagation day. On a great day, you'll pull in everything. But as we all know, those days can be few and far between. And if you've studied anything about ham radio, you know it's all in the antenna.
So here's where the rub is: Out of the box, as-is, listening to HF SSB transmissions will leave you feeling depressed. Voices will sound garbled, the "knobs" on the donut antennas won't change anything, and you might find yourself saying "this is junk" without making a couple little tweaks that SHOULD be listed in the manual.
The video I have is a POTA activation on 14.256 MHz and no, it was not even remotely intelligible at first. In fact, that guy's voice was 100% distorted and garbled and I almost gave this radio zero stars. Until I played around a little bit.
For decent shortwave or HF reception, you'll need to put up a wire antenna (or similar). I had one cut for 40 meters that I hang in a tree for QRP operations, and as you'll see in the video, I just hooked it onto one of the connection bars on the back of the donut antenna. A better idea is to wire in a good antenna with an SMA connector, but that design is 100% up to you.
WRITE THIS EXAMPLE DOWN, if you want to actually hear SSB voice on the ham radio bands:
Modulation is USB (for 20 meters of course). Mode is SW. Bandwidth set at 3kHz. LNA set to 0. And most importantly, set the BFO to +00500. It might vary for your particular radio but I'm guessing it won't vary much. That's the secret to making transmitting stations intelligible instead of distorted and garbled.
The settings listed above mean the difference between "HF junk" and "HF goldmine". This information should be in the manual, it isn't, so I put it here. And Radioddity owes me a beer on that one!
As for the advertised spectrum mode (scope), just hold down the V/M button. It's a nice function to have, although there's no documentation on how to use it (ie: tune the radio to a signal spike). But I'm sure there will be a YouTube video on that soon.
I went from wanting to give this rig zero stars and a place in my trash can to 5 full stars and "my new favorite HT" status. I'm not even joking. I reviewed the regular GS-10B (not this Pro version with HF receive) last January and it was my favorite UHF/VHF HT until now. The GS-10B Pro, with the right settings, is a dream for new and upcoming hams. The perfect entry radio in my opinion. One radio to transmit on UHF/VHF yet still receive on HF with full shortwave capabilities. The perfect radio for new technicians, I wish it had been out when I first got my tech license!
When this thing is tuned correctly and the settings are correct (listed above), the reception is actually better than my $500 QRP rig. It is impressive, when configured correctly.
I absolutely love this radio. I'll be getting a second for my go-box. 5 full stars.
Oh, and the battery from my regular GS-10B (not this Pro version with HF receive) works on this version! Kudos!!!
