IC-705 vs FTX-1 Power

In this post I will take a look at the power requirements of both radios. Again, this is not a detailed in depth scientific experiment, more in line with what the average user would do with equipment he/she may have on hand. One of the first things I did was hook the radios up to a power supply, in this case a Samlex SEC-1223BBM and I used one of those generic power meters. At idle:

That was surprising! The Yaesu uses 155% more power at idle than the Icom. One possible way to look at that is the IC-705 with a 3.3 Ah battery may have the same operating time as the FTX-1 with a 6.1 Ah battery. This makes the Icom even lighter because it needs less battery.

Next I hooked the radios up to a dummy load and Bioenno 3 Ah battery and did a key down at 5 and 10 watts to measure the power consumed. First at 5 watts.

Interestingly enough, the IC-705 is more efficient in its power usage. It is 340 mAh less than the FTX-1. Moving on to 10 watts.

The Icom again is more efficient being 240 mAh less power draw than the FTX-1. What does this mean? I think in rough terms a 3 Ah battery with the IC-705 will give you approximately the same operating time as a 6 Ah battery for the FTX-1. If you are a drive-up POTA guy, this is no big deal. If you are a remote POTA guy or a SOTA girl, power conservation may become an issue. For me, I will use my 3 Ah battery with the IC-705 and get a 6 Ah battery for the FTX-1. Note: The IC-705 with a 3,3 Ah battery weighs 1 pound less that the FTX-1 with a 6.1 Ah battery.

Now comes my first gripe with the FTX-1. The FTX-1 uses a different power connector than my other small radios. My IC-705 and my KX2 both use the same connector. Some of my other QRP radios in the past also used the same connector. Now I have to make sure I have the right connector for the radio. In the image below, the Yaesu connector is on the right. The center hole is larger than the one on the left (Icom/Elecraft).

From here, my reviews/blog post will become more sporadic as I have to get the radio setup and taken out in the field. Unfortunately for me, POTA parks are all somewhat far away and I can’t just pop over for an activation. I do have some big trips/roves planned and I will be bringing the FTX-1 with me. In general, I like the radio, it has a nice fun factor and it does some things very well. In the near future I plan on doing an a/b test with the IC-705 during a CW contest.

One thing to note is the FTX1 can use USB C to charge the batteries however it requires PD (Power Delivery) and needs 45 watts. That would mean a USB C charger similar to one you would use to charge a laptop. The IC-705 can be charged using a regular USB A to Micro USB cable. This might become important if you are trying to save wait or space.

FTX-1 vs IC-705 Physicality

I decided to take a look at the FTX-1 and see how it compares to the IC-705. I now have both (I own both) so I can take a good look at each in comparison. My intention is to treat this in a similar fashion as I did for the FT-710/IC-7300. My take is not an in depth technical review but how the radios are perceived through the eyes of a user/operator. First up is the physicality of the radios.

The screens are the same size on both radios. The FTX-1 is a little wider and the IC-705 is a little thicker.

Adding the batteries seems to equalize this as the Icom’s battery is set into the radio and the Yaesu’s sticks out.

One is wider, one is thicker, handling the two radios, I would say it’s a wash.

Weight
Here there is a difference. The Yaesu weighs more. Handling the radios, the Yaesu feels heavier than it actually is. It feels like a brick.

The FTX-1 is 6.3 ounces or 17% heavier than the IC-705. with out the batteries. Adding in the batteries.

For the Icom, I added to additional batteries to bring the total storage up to 6.3 Ah similar to the Yaesu’s 6.1 Ah battery. Even so, the IC-705 weighs less than the FTX-1 by 9.4 ounces or 16.34%. Note: The Icom with a 3.3 Ah battery weighs about 1 pound less than the FTX-1 with a 6.1 Ah battery (see the next post about power).

Size wise, I feel the radios are comparable, they would both fit in a pack or box interchangeably. Weight could be an issue for some. For those doing a POTA activation carrying their radio from the car to a park bench 50 yds away, weigh will probably not be an issue. For those who like to pack it in or do SOTA, weight would be a more critical concern. For me, my days of over hill and dale are pretty much done. If I had to travel light I would turn to my Elecraft KX2.

Next up power with some more surprises de Scott

I may have goofed with CW a little

Last year I took a CWI course to help improve my CW — and it did. During the process I had a couple of code buddies and I got involved with straight key stuff — which was fun. However, I discovered a flaw in my thinking.

When I started with CW it was back in the 90’s. We had cassette tapes to listen to and to advance your license you had to pass a code test. I read somewhere that you should start with whatever sending device you plan on using. I chose paddles. I used the Ultimatic mode for a while but eventually settled on Iambic B. I became pretty proficient with squeeze keying. Most of of my CW career was with paddles. Over the past year I was not operating CW as much for different reasons and allowed myself to get a little rusty. I love the mode and thought it was time to get back into it.

The other day I got on the air to try a few POTA contacts. It was a bit of a mess. My brain had trouble wrapping around sideswiper cootie keying and squeeze keying. You can’t do both at once. I fumbled through a few contacts and then did some off line practice. I am getting it worked out. When I am in full practice I can send at close to 30 wpm and copy an exchange at about 25 or so. Conversational CW is a bit slower at 18 to 20 wpm.

Fortunately, I can train myself out of this. First I am going back to 100% Iambic B mode. Then it’s practice both offline and online. A few minutes warmup offline and a minimum of 5 CW contacts a day. My goal is to get myself really comfortable above 25 wpm. Life’s an adventure and is more so when we are having fun living it. 73 de Scott

Yeah, I might be a little fickle

I’m not afraid to tell on myself, I can own up to it. Last night I decided to go ahead and order a Yaesu FTX-1 Field. Not without reason though. I watched a few YouTube videos from hamvention with John from Yaesu talking about the FTX-1. He mentioned that the performance of the FTX-1 would be similar to the FT-710. That could be impressive. I just finished up a review on my FT-710 so I have a feel for the radio.

Another cause and effect was yesterday, I pulled my IC-705 out getting it ready for some POTA activations. I had been remiss doing QRP CW activations focusing instead on low power digital with full size radios. I have been feeling the urge to brush up on my CW skills. Back to the 705, I like the radio a lot. It does indeed push all of the buttons. I was holding it in my hand thinking it’s not so bad for a portable radio and the FTX-1 is only a little bigger…I thought I might do another comparison series this time between the 705 an the FTX-1. I have a couple of big trips planned for the fall and winter and these radios will do nicely.

Another reason that pushed me toward the FTX-1 was the price of used radios, they are over the top right now. I was looking at a KX3 and it was the same price as the FTX-1. Even some of the other used radios were more than I cared to spend for them. One thing I forgot to mention, is I have grown used to waterfall radios. I have learned to use them to help me find places in the band to operate and to do a real time check on propagation. It’s amazing what you can glean from those screens.

Hopefully, over the next couple of months I’ll put the IC-705 and the FTX-1 through their paces. Up front I will say that I have a preference for Icom radios, but the FT-710, KX2, and TS-890s have found places here at the ranch. I am not adverse to using different brand radios, I use whatever fits me best.

The new radio should be here in a couple of days and then the games begin. This should be fun. 72 de Scott

QRP QRMe

Over the past couple of years, I have spent a lot of time taking what I call big radios to the field. These are 100 watt radios that I run at reduced power usually between 20 and 35 watts. I can run digital modes all day long on a big radio at this power and it won’t even get warm. I usually take them out for a weekend camping trip.

That has gotten a little stale, I feel I have a good understanding of how those radios and antennas work and I have made 1000’s of contacts all over the world. It’s time to do something different. I have 2 wonderful QRP radios, a KX2 and an IC-705, that haven’t seen a lot of use. I have also let my CW skills slip a little. Change is in the wind. I am planning some trips using my little (QRP) radios. in addition, I may spend a few nights in a motel rather than camp. Each day I am out, I can mini rove and do a couple of parks instead of just one. I feel the change will be refreshing, kind of going back to my POTA roots.

This fall, I am planning another multi-state rove. This will be a multi-day rove hitting a park in a state and moving on. It will be a nice drive and a lot of fun. I want to try my hand at quick set-ups and tear downs. The beauty of amateur radio is the diversity of things you can do. Sometimes, you gotta due a few things for fun. 73 de Scott

Why I didn’t Preorder the Yaesu FTX1

As information started coming out about Yaesu’s new QRP radio I was tempted to get one. However, the more I learned the less I liked about it. I have an Icom IC-705 and an Elecraft KX2 for QRP radios. My big field radios are an Icom IC-7300 and Yaesu FT-710F. I am looking for another QRP radio to do a long term review. I considered the FTX1 but gave it a pass for the following reasons.

Price. An IC-705 cost $1349.95 at HRO. The FTX1 cost $1499.95 but to be truly compatible with the IC-705, you have to add Bluetooth ($54.95) and GPS ($69.95). this brings the total to $1624.85. A spare battery for the FTX1 is $199.95. The Icom battery (BP-307) is $135.95; however, knockoffs on Amazon can be had for 2 for $59.95. I use them and they seem to work just fine. Another point are the antenna tuners. The AH-705 sells for $359.95 and can tune long wire and coax fed antennas. Yaesu chose a different path they have one tuner for coax fed antennas and one for long wire each costing $319.95 or $639.90 for both.

The optima package. It cost $1899.95 to give you a 100 watt option. To put this in perspective, you can buy a FT-710 Field for $884.95 and a FTM-510 for $499.95 for a total of $1384.90. Plus you get an antenna tuner included with the FT-710 and the 710 probably has better performance than the FTX1 on HF. As a side note, the FT-991A sells for $1229.95.

Performance. Yaesu was pretty mum about the performance of the FTX1. With the FTDX101, FTDX10, and FT-710, they touted the Rob Sherwood numbers long and loud. The only thing they said about the FTX1 was it had the same Analog to Digital Converter (ADC) as the FTDX10. ADC’s are all pretty similar in all of the SDR radios. So where does the FTX1 fall? Is it like the FT-710 or is it more like the FT-991A or the FT-891? For POTA and SOTA using SSB this is probably fine Rob Sherwood recommends a Dynamic Range Narrow Spaced number of 80 dB for contesting. For CW that number increases to 90dB. The FT-891 and the FT-991 are in the 70’s range.

My friend Thomas K4SWL who is attending Hamvention put his hands on a live FTX1. His first impression was it was much bigger than he imagined. He decided to cancel his reservation for a FTX1. Looking at how things attached to the radio, I had the same thoughts. If I am going that large, I’ll bring my IC-7300 or my FT-710F. I am curious about the current draw of the FTX1 at idle.

As folks get their hands on the radio, more details will come out. Hopefully Yaesu will be more forthcoming with information, we shall see. It seems to me that Yaesu did not listen to the QRP/POTA/SOTA community when building this radio. For sure the pricing and size seem out of whack. As for me, I am still looking for another radio to review, but at this time I will give the FTX1 a pass. 73 de Scott

Paddle Widget

I have a set of Begali Adventure Paddles. They are wonderful paddles. I have the mount for my IC-705, KX2, and desktop. Each mount works well. However, there are times when I do not have a stable platform for my radios or the paddles. At these times I usually hold the paddles in my hands. My go to handheld paddles are my N0SA SOTA paddles. I got mine from his last run. They are an excellent paddle.

I tried holding the Adventure paddles in my hand but I would cause errant dits and dahs. I first thought I would 3D print a box for the paddles–to much thought. I then thought about getting some square aluminum tubing. Too expensive. I scrouged around in my shop and found some 1″ angle aluminum. Perfect. Before I go on let me explain, that this was done with hand tools. A hacksaw, files, hand drill and drill bits. I also used a Dremel tool a little. This project is far from perfect. I never let perfection be the enemy of good enough.

Here is the piece roughed out.

The slot is where the finger guard mounts to the bottom of the paddler using a 4-40 screw. Mounted it looks something like this.

The guard extends past the end of the paddles to help protect the cable where it enters the paddle.

In use the paddle/guard combo looks like this.The guard keeps my index finger from touching the paddle lever and allows me to put my thumb below the paddle lever on the other side. It is very comfortable to use even with my large mitts.

A coat of primer, followed by paint and a clear coat and viola!, it is finished.

I will let it cure overnight and it will be ready for the next adventure. 73-de Scott

Yaesu FT710 final Review and Where to Go From Here

I’ve had the Yaesu FT710 for a while now and used it mainly in the field. That was and is my intent for this radio.  In general, I feel if I am doing an activity like Field Day or a multi-day POTA activation, and I am not carrying my gear more than a few feet, why not bring a full sized but compact radio.  These radios have more operating options and the controls are generally easier to use.  In addition, running a 100 watt radio at low power (20 watts or less), the radio doesn’t even get warm.  The radio works well with digital modes.  It wasn’t that long ago that Yaesu’s were a real pain to run digital.  Icom’s have had an easy interface since the IC-7100.  Today, the FTDX10 and the FT710 both are on par with the Icom’s when it comes to digital modes.  With CW, both brands are about equal.  In general, I feel both radios are interchangeable and it would be the matter of personal preference which would determine which is best for you. In the next couple of paragraphs I will describe the pluses and minus’ of the FT710 and the IC-7300. John WD8LQT provided input from his use of my radio during the WGARS Spring Fling.

Attenuation.  The IC-7300 only gives you 18dB of attenuation while the FT710 give you 3: 6dB, 12dB, and 18db.  Your more expensive radios typically have 3 like the FT710.  In an SDR radio, attenuation is your friend.  Preamp should almost never be used.  The nod goes to the FT710.

CW Tune.  Both radios have autotune but the FT710 has a CW tuning indicator right below the S-meter. I find myself using it quit a bit.  Some CW ops crank their filters way down and if you are a little off frequency, they won’t hear you.  My buddy John WD8LQT, also liked this feature. Nod goes to the FT710.

Sound quality.  The FT710 sounds a little better, but the IC-7300 has a lower noise floor.  I do not find either one objectionable. YMMV.  Draw

Waterfall.  The IC-7300 has an averaging waterfall and the FT710 does not.  That means that the FT710’s waterfall has to be manually adjusted every time band conditions change.  John noticed that when sending CW the waterfall would flash rather brightly, enough to be a little distracting. This may have been due to the waterfall level not being adjusted properly, but it is not an issue with the Icom.  Nod to the Icom.

Ergonomics.  Here the IC-7300 is the clear winner.  It has more of the right buttons on the control panel and it is easier to get to the most needed controls. The 7300 gives you 3 adjustable filters and the Yaesu gives you 2.  To adjust the Icom, grab a knob and give it a twist.  On the Yaesu, push a knob, twist the knob, push the knob, twist the knob.

Power consumption.  The FT710 uses about 1.2 to 1.3 amps at idle with normal volume.  The IC-7300 uses about 0.85 amps.  This doesn’t matter if mains power or generator power is available but when working off of batteries this can become an issue.

Sensitivity and Selectivity. The Icom has a lower noise floor, -133 vs -127 dBm for the Yaesu. Before I get into selectivity let me explain a little about Rob Sherwoods numbers.  Most people quote the 2 KHz blocking number, that comes with a couple of caveats. First, for the most part Rob measures 2 KHz blocking with a 500 Hz filter. That’s a CW filter.  Sideband filters usually run 2.4 KHz plus.  Unless you’re a CW op, this number is irrelevant. Here is what Rod Sherwood says, “I decided to sort the table on my website by close-in dynamic range at 2-kHz spacing. This was the “acid test” for CW contest / DX pile up operation.” He further quantifies his research with the following numbers. “What do you need in the way of close-in dynamic range? You want a number of at least 70 dB for SSB, and at least 80 dB for CW. A 10 dB safety factor would be nice, so that means you would prefer 80 dB for SSB and 90 dB for CW.” In the past I have compared the IC-7300 with the FTDX10 and the FT710 during a CW contest. What ever I could hear with one, I could hear with the other. The Yaesu’s had a little less ringing but I had no problem copying the signal from any of the radios.  

What this means is either radio will serve the vast majority of operators well.  Whatever your personal preference is, go for it.  There are things I love about the FT710 and there are things I love about the IC-7300. I never feel at a disadvantage with either radio.  I plan on keeping both.

Where do I go from here? That’s a good question. I don’t have anything in line to review. I have decided to take a step back from EmComm for a while.  I’ve been doing a lot of digital lately and need to get back to the joys of CW. I also have a couple of QRP radios that need to be taken out and used.  I still enjoy the smaller radios.  I’ll take a big radio on a camping trips/Field Days and may take a little radio for a quick activation. Sometimes it’s nice to grab a small box or bag and go. I have some antennas I haven’t used in a while, I need to get them out.  

Thanks for hanging with me.  I appreciate your company.  73 de Scott

WGARS Spring Fling 2025

Today was the club’s semi-annual outing and this spring it was one of our old haunts, Cheaha State Park US-1037 in the fine state of Alabama. There are 3 things we as a club like to do, we like to eat, we like to socialize, and once in a while we talk on the radio.

As usual, food was in abundance.

We had several stations set up under the pavilion. QRM was held to a minimum. We had Xeigu G90’s, Tru-SDR, Icom IC-705, and my Yaesu FT-710. I set the radio up and turned it over to the club President John WD8LQT. John, like me is a CW op and I wanted his opinion of the FT-710. I didn’t have to twist his arm too hard. The setup was the radio feeding a Chameleon micro transformer with a 12’ whip and about a 20’ counterpoise. The radio was powered by a 20 amp-hour Bioenno battery and the paddles were a Begali Expedition.

Band conditions were poor and it took John most of the time at the park to get his 10 contacts. There were stops for eating and chatting. Early in the activation, I decided to change antennas to be sure we had an atmospheric issue and not an equipment one. I had my Diamond RHM-12 which recently proved itself to be a good performer. Once the switch was made and some searching through the bands, John started making contacts on 20 meters. I believe it was atmospherics and not the equipment. John got his 10 contacts and we called it good.

John’s comments about the FT-710 were quite favorable. Like any radio, there are pluses and minuses. In general he thought it was a very good radio for CW. There is more commentary from John on the YouTube video posted below. John did have one epic fail. The ear buds he was using which looked rather ancient finally gave up the ghost. I took it upon myself to intervene and unceremoniously threw them in the trash. John will thank me.

My review of the FT-710 is drawling to a close. I find that I like the radio. It performs well for its price point and has some features found on more expensive radios. It has its quirks as all radios do, but none that I find overly objectionable. I plan on keeping the radio and it has found a place among my field radios. I imagine the radio may make an appearance during this year’s Field Day.

Hamrs Pro

This past trip I was able to check out the new Hamrs Pro app. I must say I am impressed. I spent some time prior to my trip setting it up for a POTA activation. Here is my current setup:

Hamrs uses FLrig to interface the radio with the app. When the radio is connected, frequency, band, mode, and power is updated in the app. In addition, Hamrs Pro will set the RST to either 59 or 599 depending on the mode. Another nicety is when you add the POTA park number in “My Park” it will automatically add the Maidenhead Gridsquare to “My Grid”.

Tabbing is straight forward. It goes from left to right and top to bottom. In my set up I have received RST first since that is the first one I get and then a quick tab and I add mine. Time on is automatic. I always believed that computers should work for us and not the other way around. With Hamrs Pro, it does most of the heavy lifting for you.

Another place where Hamrs Pro shines is the POTA spots.

There is a lot of info on the page to include compass heading and distance. If you click on the RIG button, Hamrs Pro transfers the frequency and mode to your radio. If you click the Copy button, the information is copied into the log. Add RST, hit save and you’re done. Pretty slick.

So far the only improvement I can think of is using Hamrs Pro with FT8. I don’t see an easy way to interface Hamrs with WSJT. This is not a big deal. All I do is log FT8 contacts in ACLog export the log as an ADIF, and then import the ADIF into Hamrs. It is easier than it sounds. Another way might be to use the WSJT log function and import that into Hamrs Pro.

Hamrs Pro with a $2 a month subscription allows you to sync your logs across platforms. I have Hamrs Pro on my Mac, IOS, IPadOS, and Windows. As along as I have internet or WiFi, they sync. This is great because I mainly use Windows for radio stuff and Apple for everything else. I can create a log on my Evolve III or my iPhone, and when I get home I can upload the log to POTA on my Mac — easy peazy.

I have been using Hamrs on and off since the beginning. This is a hugh step –in the right direction. I can see this as becoming my go to logging app. A lot of thinking and work has gone into Hamrs Pro. I can only see it getting better. Good job Hamrs folks. de – Scott
