Icom IC-705: Let’s see how long it’ll receive with supplied BP-272 Li-ion battery pack

The shortwave radio listener part of me might actually be more excited about the Icom IC-705 than the ham radio operator part of me.

The IC-705 has a number of features for ham radio operators who also enjoy broadcast listening. For example, it sports:

  • a general coverage receiver,
  • good performance specs,
  • notch filtering (both manual and automatic),
  • Icom twin passband filtering,
  • an AM bandwidth filter maximum width of 10 kHz
  • built-in digital recording of both received and transmitted audio,
  • audio treble/bass adjustments,
  • and battery power from Icom HT Li-ion battery packs

The Icom IC-705 ships with an BP-272 Li-ion battery pack and since the announcement last year about the IC-705, I’ve been curious how long the BP-272 could power the IC-705 in receive only.

A real-world RX test

Yesterday morning, I resisted the urge to hunt POTA and SOTA stations with the IC-705 and, instead, spent the day simply listening.

I started the experiment with a fully-charged BP-272 7.4V 1880 mAh battery pack (the pack supplied with the IC-705). At 9:00 in the morning, I unplugged the IC-705 from my 12V power supply and ran the receiver all day on just the battery pack.

I made some practical changes to maximize play time: I turned on the screen saver, turned off GPS, set the LCD backlight auto adjustment to 2%, and set the screen timer to turn off after 1 minute.

I ran the volume somewhere between low and moderate and only raised it to what I would consider very loud a few times to copy weak signals. I listened to AM, SSB, and FM signals across the spectrum, but primarily cruised the HF bands.

Of course, I never transmitted with the IC-705 during this period (saving that for the next test).

I probably could have done more to decrease current drain, but frankly I wanted this to be based on how I’d likely configure the rig for use on an SWL DXpedition.

Results

I unplugged the IC-705 from the 12V power supply at 9:00 local and the radio auto shut down at 16:39 local: a total of 7 hours, 39 minutes.

Honestly? I’m fairly impressed with this number mainly because it’s based on the smaller battery pack. The supplied BP-272 pack has 1880 mAh of capacity. The optional BP-307, on the other hand, has 3150 mAh of capacity.

If I decide to keep the IC-705, I will be very tempted to purchase a ($130 US) BP-307 pack as well.

Next test: How long can the IC-705 last on battery during a POTA activation?

As early as today, I will see just how long the BP-272 pack can operate the IC-705 during a POTA activation. This will be a true challenge on the smaller battery pack since POTA activations require a lot of transmitting (constant CQ calls and exchanges). There’ll be no lack of calling CQ on a day like today when propagation is so incredible poor.

The Icom IC-705 has landed at SWLing Post HQ

Yesterday, I received my new Icom IC-705 QRP transceiver (along with two FT-60R HTs) from Universal Radio.

I got home pretty late yesterday afternoon so haven’t had a lot of time to put the IC-705 on the air.

I did tune to the Voice of Greece and REE last night and, must say, was pretty impressed with AM mode.

This morning, I also worked two CW stations and one in SSB on the 40 meter band from my home.

Very early days, but I get the impression the IC-705 receiver is top shelf. At least, I like what I’m hearing.

So far, the only negative I’ve mentally noted is the difficulty in propping up this radio for use on a desk. It’s a little awkward. No doubt, a number of 3rd party solutions will soon emerge. I’m personally hoping someone will design a 3D printed stand/cradle.

Indeed, a 3D-printed front panel cover would also be nice because I do worry about the touch screen display being damaged in my backpack. Being a bit of a picky backpack geek, I did not opt for the custom Icom LC-192 backpack (completely subjective: just not my style and not waterproof). The IC-705 can be secured in the LC-192 so that the front panel is well-protected.

The IC-705 backlit display is very easy on the eyes–I hope it’s as easy to read in sunlight outdoors. We’ll soon find out because I’m certainly taking it to the field!

My Icom IC-705 is inbound…sharing my predictions

I was contacted by Universal Radio yesterday afternoon with  a tracking number for my Icom IC-705. It will arrive by Monday evening.

A number of SWLing Post readers in the US and UK have notified me that their IC-705s have also been shipped and a few have even been received already.

I’m really looking forward to checking out the IC-705. The preliminary reviews (overviews, really) have been pretty positive. I found the IC-7300 to be a fabulous rig and the IC-705 smacks of the ‘7300. The ‘705 even includes more features than the ‘7300 (multi-mode VHF/UHF, D-Star, Wifi, and built-in GPS to name a few) although lacks an internal tuner.

I’ve received more questions about IC-705 and the TX-500 than I have any other radios this year. Both, in many senses, are ground-breaking in their features, (and in the case of the TX-500) form-factor and build.

If I’m being honest, I was more excited about the TX-500 because it simply suits my field operating style better (my full TX-500 review will be in the Oct 2020 issue of TSM).

Since I haven’t received the IC-705 yet and haven’t read any truly detailed reviews or comparisons, I’m going to do something I’ve never done before and share a few of my personal predictions.

Predictions

I’m human and can’t help but form a few expectations/opinions prior to a thorough rig evaluation. That and, having owned a number of their products, I’m very familiar with Icom as a company. I’ll probably regret this later, but here goes…

I suspect:

  • I’ll like the touch screen display more than I think I will. I’m not a big fan of color backlit displays in field radios. I prefer simple high-contrast LCD displays that are readable in full sunlight. I’m hoping Icom will have optimized the IC-705 display for reading outdoors.
  • I’ll be able to operate the radio without referring to the manual because I’m so familiar with the IC-7300.
  • I’ll really miss having a built-in ATU on a rig in this price class. Feels like a missed opportunity, however seeing the inside of the IC-705, there really isn’t a lot of spare room. With that said, I plan to review the mAT-705 ATU compact external tuner and hope it’ll pair nicely.
  • I’ll be disappointed with the amount of run time I’ll get from a fully-charged BP-272 battery pack. I really hope I’m wrong about this one. Icom did some serious engineering on the IC-705 to lower the amount of current needed in receive. We’ll see if that paid off and if it can compare, for example, to the run time I get from the rechargeable battery pack in my Elecraft KX2.
  • I’ll be very pleased with some of its features like CW and Voice memory keying for POTA and SOTA activations.
  • I’ll still find D-Star complicated to use even though, hypothetically, the IC-705 can connect directly to D-Star via WiFi. I hope I stand corrected on this point.
  • I’ll struggle to find the perfect padded pack to house the radio. I’m a bit of a pack geek/snob and don’t really like the Icom LC-192 backpack. I’ve no intention to order it even though it’s designed to work with the radio. So while this doesn’t apply to 99% of my readers, it’s a big deal in my world. 🙂 I’m sure I’ll sort out a solution.
  • I’ll feel some buyer’s remorse when, in 6 months, the IC-705 price drops a couple hundred dollars. That’s okay. I see it as taking a bullet for my readers (and, let’s face it, I love new radio gear). Plus, I’m banking on the notion that the IC-705 will make for a capable QRP EME transceiver.
  • I’ll love the built-in digital recorder for making off-air shortwave broadcast recordings (although I do fear I’ll find the AM audio filter too narrow).

Again, these are completely off-the-top-of-my-head predictions and based on no hands-on time with th IC-705. Next week, I’ll start to see how many of these predictions are correct and how many I totally missed.

I can tell you this: I’m not sure I want to see the invoice from Universal Radio. It includes the IC-705, two Yaesu FT-60R HTs, and some Anderson PowerPole connectors! Although I’ve had the IC-705 on order for ages, I added the HTs and connectors at the last moment because they don’t seem very pricey when you’re already at the $1300 US mark, right–? (Shhhh! The FT-60Rs are a gift for my daughters who take their Technician test this weekend!)

How about you? Do you have an IC-705 on order? What are your predictions and thoughts? Please comment!

Phillip loves the Icom IC-R30, but frustrated with mono audio out

Many thanks to SWLing Post contributor, Phillip Novak, who writes:

A question or perhaps comment on the Icom IC-R30 that I’m hoping SWLing Post readers might shed some light on.

I’m a very new and extremely pleased owner of one of these units for the past 2 weeks. Aside from receive capability, usability is a big deal for me and this thing has proven to be a joy! The menus, buttons and build quality just feel great and frankly, I’m pretty happy about having made the “investment”.

So, it was with great excitement that my wife and I have the week off at the cottage – more so for me, as I was looking to really break the R30 in while sitting on the lake shore.

And then …. I was extremely disappointed to find out that the r30 headphone jack is mono (just like the IC-R6 that I already owned). On top of that, the jack is slightly recessed into the body of the unit, which renders the mono-to-stereo split adapter useless! (I really thought they would have changed it!)

Someone, please enlighten me as to why Icom would choose a mono plug!

It’s funny you mention the recessed plug as I had the same issue with a portable recently–the audio out port was recessed to the point that only the provided cheap earphones would fit!

Perhaps SWLing Post readers and IC-R30 owners can provide you with a simple solution? Of course, you can always purchase or build a mono-to-stereo adapter or patch cord–one with a slim profile to fit in the IC-R30 audio port recess (that’s the tough part, of course). But perhaps there are even earphones that have this functionality built-in? I honestly don’t know. Any ideas, readers? Please comment.

And, Phillip, we’d welcome your review of the IC-R30!

Icom IC-705 approved by FCC: pricing and availability update

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.”

Shipping/Availability

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.

Pricing: $1,299.95 US

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.

Review

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

Which would you choose as a first radio–the Icom IC-7300 or Xiegu G90?

Many thanks to SWLing Post contributor, Paul, who writes:

This came to me from a friend; he is curious about choosing between the Xiegu G90 and the Icom IC-7300 for his first rig. He has money to buy the Icom which is $999 right now after rebates, but wants to know if he is really getting twice the radio for the Icom, vs the Xiegu, or are there other good reasons to get the 2016-introduced Icom, vs the newly introduced Xiegu.

Maybe this can be a posting to ask your readers? Greatly appreciate it.

Thanks very much
Paul

Thank you for passing along the question, Paul.

While I almost consider this to be an “apples to oranges” question, let’s approach this from a couple of different operator perspectives and truly explore the decision.

I like both radios for different reasons, but first, I’ll tell you what my decision would be if I were in in his shoes…

The Icom IC-7300 SDR transceiver

I would choose the Icom IC-7300

While the Icom IC-7300 does cost twice the amount of a Xiegu G90, it’s a much more versatile transceiver. There are almost too many IC-7300 features to list here, so I’ll mention a few that immediately come to mind, focusing on features the G90 lacks.

For one thing, the IC-7300 is a 100 watt radio, thus the max rated power output is five times that of the Xiegu G90.

The IC-7300 doesn’t require an external sound card for digital modes. Simply plug the radio into you PC with a USB cable, and with your favorite application (like WSJT), you can operate any number of digital modes. (I found configuring the G90 for digital modes to be a bit frustrating.)

The IC-7300 also covers the 6 meter band–the G90 tops out at 10 meters.

The IC-7300 has useful features for contests and field operation like:

  • voice and CW memory keyers with beacon mode,
  • native transmit and received audio recording,
  • a large touch screen display to quickly enter frequencies and adjust settings,
  • audio EQ on both transmit and receive,
  • a built-in bail
  • notch filters and Icom’s twin passband tuning

Again, by no means is this a comprehensive list–just some of the features that come to mind.

As a first rig, the IC-7300 can take you into any aspect or mode of the HF band your friend cares to explore. It must be one of the most popular HF radios on the market right now, so there’s also a massive user and knowledge base out there on the web.

The IC-7300 also has better transmitter specs, producing a cleaner signal than the G90, especially in CW (the G90 is known to produce key clicks and not recommended for use with an amplifier). It also can handle close-in signals better than the G90 and has a higher dynamic range. Overall, it has better specs than the G90.

For a more detailed look at the IC-7300, check out my full review.

Why one might choose the Xiegu G90 over the Icom IC-7300

The Xiegu G90 with upgraded encoder

Let’s get an an obvious point out of the way first: the G90 costs half that ($450) of the IC-7300 (generally $900-1,100). This could leave your friend with even more money to invest in an antenna. As I’ve said so many times before, a radio is only as good as its antenna!

If your friend plans to operate primarily in the field, the Xiegu G90 is much more portable option. The G90 is very compact and weighs a fraction of the IC-7300. The G90 also draws less current in receive mode, so is much kinder on a battery. It also has built-in side extensions to protect the front and back panels while being transported.

The Xiegu G90 has a detachable face plate which would come in handy for mobile installations (although, admittedly, there are a number of better mobile transceivers on the market).

My full review of the Xiegu G90 is in this month’s issue (Aug 2020) of The Spectrum Monitor magazine. It’s nearly a 4,000 word review so is one of the longer ones I’ve produced. If your friend wants to make a decision soon, he/she might purchase this issue to fully explore this rig.

Another option: Yaesu FT-891 and LDG Z-11 Pro 2 external antenna tuner combo

If your friend is seriously considering the Xiegu G90, then I have to assume he/she has portable operation in mind.

Making this assumption, I would also suggest they check out the Yaesu FT-891. Like the IC-7300, it has a full 100 watts output and also covers the 6 meter band. Like the G90, the front panel can be separated from the radio body for easy mobile installation.

Although I have never reviewed the FT-891 (although I plan to before the end of the year), the radio has an almost cult-like following among SWLing Post readers. It’s also a favorite rig of Parks On The Air (POTA) activators because of its 100W output, relatively compact footprint, and great audio characteristics. The G90 and IC-7300 both are based on SDR architecture, the FT-891 is a triple conversion superheterodyne general coverage receiver.

Unlike the IC-7300 and G90, however, the FT-891 lacks an internal antenna tuner (ATU) and I’m guessing your friend wants one based on the fact both the G90 and IC-7300 have one.

The LDG Z-11 Pro 2 ATU

No problem! The Yaesu FT-891 is one of the best bang-for-buck transceivers on the market. The price at time of posting is $609 after rebates. That leaves room to purchase a benchmark portable HF+6 meter antenna tuner. I personally love the LDG Z-11 Pro 2 which would only set them back $169. I’ve owned one of the predecessors of this ATU for nearly a decade. It’s located outdoors, in an enclosure and serves as a remote antenna tuner for my multi-band sky loop. It has operated flawlessly through seasonal temperature extremes and powered by a 15 year old  12V gel cell battery that is charged off of a 5 watt PV panel and Micro M+ charge controller.

The FT-891 and Z11 Pro 2 ATU combo would total $778 which is a nice compromise between the $1,000 IC-7300 and $450 G90.

If your friend wanted a more compact option than the IC-7300, and better specs and more power output than the G90, this FT-891/Z-11 Pro 2 combo would be hard to beat.

Don’t Forget Antennas and Power

As I mentioned before, do your friend a favor and remind him/her to set aside a budget for an antenna.

If you build your own wire antenna, you can create an amazing one for $50 or so in quality ladder line and wire–at least, that’s about what I put into my sky loop antenna. Retailers like Universal Radio, HRO, and Gigaparts stock quality pre-made wire antennas that cost a bit more, but are pre-tuned, durable and very easy to deploy. The type of antenna you can install is totally dependent on the environment around your home, access to your radio room, and any local interference you might need to mitigate.

Of course, all of the radios mentioned above need a DC power supply. There are many on the market from lightweight switching power supplies to heavy linear supplies.

I would not choose one of the cheapest ones you can find because switching power supplies especially can inject noise. I’m a big fan of the Powerwerx SS-30DV which will typically cost around $110 at ham radio retailers (although, at present, it’s one of the many items out-of-stock due to the Covid-19 pandemic). It hits the sweet spot for me and is a little workhorse!

What do you think?

As I always say: radios are a personal choice. Specifications and features make for convenient points of comparison, but often choices are made based on a user’s own needs and operating style.

Between the Xiegu G90 and Icom IC-7300, which would you choose as a first rig? Can you think of a better compromise?  Please comment!
