Note: this is a cross-post from our other radio blog, the SWLing Post.
This weekend at Tokyo’s Ham Fair 2019, Icom announced an innovative transceiver to their line-up: the Icom IC-705 QRP transceiver.
The IC-705 introduces several industry firsts for a backpack portable radio:
- It uses the same BP-272 Li-ion Battery pack as the ID-51 and ID-31 series D-Star handy talkies. To my knowledge, this is the only HF transceiver that uses battery packs that can be swapped so easily in the field–like one would swap an HT battery pack
- It has a general coverage receiver that spans a whopping 0.5 to 148 MHz
- It sports a full color, touch screen with spectrum and waterfall displays
- It includes the D-Star digital voice mode
- A GPS receiver
- Bluetooth connectivity
- A MicroSD card slot for memory storage, screen captures and recordings
All of this appears to be included, not add-on options.
The only IC-705 omission, in my opinion, is an internal ATU (antenna tuner). Something I would have expected, but not a deal-breaker for those of us who could really benefit from the amount of features this radio offers.
There is no word yet on pricing or availability, but you can count on us to post these details once they’re available. If you would like to follow updates, bookmark the tag: IC-705
We will also review on the Icom IC-705 as soon as it’s available.

A surprise from one of the “Big Three”
The “Big Three” transceiver manufactures–Icom, Yaesu and Kenwood–have not shown a lot of interest in backpackable QRP radios over the past two decades.
By “backpackable” I mean QRP transceivers specifically designed for portable use in the field–radios that typically have built-in battery options, internal ATUs, and designed to be lightweight shack-in-a-box units.
Yaesu introduced the FT-817 almost twenty years ago and it lives on today (with modest upgrades) as the FT-818. Kenwood has no portable/backpackable HF QRP radio at this point.
I bet the IC-705 is being introduced today because Icom sees a strong market among field-portable operators who enjoy travel and outdoor radio activities like SOTA (Summits On The Air) and POTA (Parks On The Air). In addition, many ham radio operators live in neighborhoods that are either plagued with radio interference (RFI) or don’t allow antennas to be installed outdoors. Portable radios liberate ham radio ops from their shacks and allow them to set up a station far away from noise or home owner’s associations.
Again, I’ll be in touch with Icom about the IC-705 and will share updates here when they’re available. I’m looking forward to evaluation this rig when it hits the market!

The radio looks super but a bit big for backpacking, Icom intends to sell an optional backpack for it which is a good idea, they also did this with the IC-703, this will be a very handy asset for backpackers, SOTA people or park activators. However I think the radio is not weatherproof (like so many others) and have connectors at both sides which make it less handy to use it like a “handy”.
Low power usage, being weatherproof and an internal tuner would make this radio a challenger for the KX2/KX3, but selling my KX3 to buy this radio will never happen. Probably promising for Japanese operators who have a low power licence.
I’m willing to bet that the IC-705 current drain in RX will be higher than the KX3/KX2 since it sports a color touchscreen, etc. I certainly wouldn’t sell my KX3, but the IC-705 is still tempting in that it includes so many modes and bands. Since it has an internal sound card, it would run digi modes natively (w/out the need of an external sound card interface) like the ‘7300. I think the size would be fine for backpacking–1kg is pretty reasonable and roughly what the KX3 weighs with batteries.
You mention “However I think the radio is not weatherproof (like so many others)…”–I’m curious what other QRP transceiver models are weatherproof. The only one to my knowledge is the yet-to-be-released TX500.
Thanks, OM, for your comment!
Cheers & 73,
As said, “Low power usage, being weatherproof/waterproof and an internal tuner would make this radio a challenger for the KX2/KX3” in which I want to say I miss weatherproof radio’s from all big vendors. It is not always fun to put a 1200€ costing radio in the rain on a sota top (as my KX-2), and knowing the radio is not waterproof. Of course there are ways to prevent water/dust going into the radio’s…but it is always a hassle. I also find that the kx2/kx3 is not waterproof is a design error.
The IC705 DOES NOT have an internal ATU. That’s a deal breaker for me……and I only use resonant antennas. Watch some YouTube videos on QRP Portable operations. Take note on how many hams use non resonant antennas.
Another issue for me is the battery choice. They use a 2000 ma battery. The 705 uses a display like the IC7300 does and the 7300 draws 800 ma. That equates to 2 hours and 15 minutes of receive time. Now enter making a few Q’s. That battery is going to be dead in no time.
But, putting those two, what I consider flaws, aside…..I still think the 705 is a great full featured little radio. But if you are going portable, you better carry along a much bigger battery. Remember to also use a good resonant antenna.
Looking forward to seeing what this radio is going to sell for?
I agree 100% with you, as I’m a long time QRP’er for 55 years now.
A good 10:1 internal tuner is a must. For the battery, it is the same thing
with the FT-817ND I never use the internal battery simply because not much autonomy.
Anyway, time will tell, and I can’t wait to read the instruction manual for more détails.

I use LIFEPO4 FROM K2 Battery, k2battery.com and I’m very satisfied.
I have to admit, I’m a little skewed. I have a IC-7300. I love the waterfall display! The idea of having that in a qrp with that would be fantastic. I hope there is the ability to go to a low power mode and blank the display when I’m not looking for traffic. The built in swr meter will help tuning the odd antennas we come up with. A small external 10W tuner should be made by some company (hint)! The big thing to me is all mode with 2M/440 included. Plus the biggest feature. This is a SDR! Hence things you want, short of a tuner, can be done later after launch! Things like super low power monitoring and extra power saving modes, plus things we haven’t thought of yet. I’m willing to suffer SDR growing pains with ICOM……keith
While nany say shortwave is dead we seem to have a revival of it. Many hams includibg myself value the ability to gather
News and weather from distant stations and compare our results.An important asset if the grid goes down as it is doing
In the coastal areas of texas.
