With the FTDX-10 at $1400, and the FT-710 at $1300, both 100W HF/6M transceivers…very strange Yaesu marketing strategy.

Indeed... The specification of the FT-710 seems to be inferior to that of the FTdx10 in most, if not all, respects, so it is difficult to see why they have released it.

Martin (G8FXC)

Their price points go against all normal retail marketing of “good, better, best” offerings. Would make more sense if they had the ‘710 or ‘10D (not both) at $1200, then something new at $2200, and the ‘101D at $3200…with logical upgrades as you climb the price ladder. A $2200 price point radio would be a nice compromise that no other manufacturer offers. At the present $100 difference between the ‘710 and ‘10D, they’re just gonna “cannibalize” each other.

I don’t get it, but what do I know ;).

Their hands are somewhat tied by ICOM - the FTdx10 is very close to the IC-7300 in functionality and performance and would not stand a significant price premium over that radio. One possible interpretation is that they intend to withdraw the FTdx10 and just have the FT710 and FTdx101D. The trouble with that is that the FT710 seems to be a direct sampling rig - much like the IC-7300. The big advantage of the FTdx10 over the IC-7300 is that it is not direct sampling.

Looks like it comes with that "special" side speaker, I wonder if there is another speaker in the main unit?

So its about the same price at the FTdx10???
Its smaller and lower performance as a direct sample setup like the 7300 yet it costs about the same?
Why not get the 10 then?

The big advantage of the FTdx10 over the IC-7300 is that it is not direct sampling.

Martin (G8FXC)
The 710 is described by Yaesu as a "direct sampling superhet" with an IF of 18 KHz on CW/SSB and 24 KHz on FM/AM.

I'm not sure how that compares to the IC-7300 or the FTDX-10...

As an IC-7300 user, that is only used for "car portable" 6m and 4m contests, the ease of use of the 7300 is important as is the likely lower current on RX of the 7300. The spectrum scope of the Yaesu radios lacks averaging and as such is pretty much useless to me. The receiver in the 7300 is more than adequate for my purposes.

In common with most Japanese radios, I wonder if the 710 has one of those difficult to replace surface mount lithium clock batteries? Those batteries are one of the most stupid design decisions ever made.

It does, though the block diagram seems to be missing several components that you would expect to find on a superhet. We really need someone with the necessary training and experience to do a hands-on test and give us the definitive answer...

Martin, for a guess, and it’s only a guess, the 710 might avoid the expense of narrow roofing filters in favour of the wider bandwidth SDR approach.

Having “non roofing filter” radios these days in the form of an Elecraft K4D, IC-7300 and IC-9700, I don’t miss the roofing filters that I had in a K3.

When I had a QRO neighbour around a mile and a half away, on 80m CW with the low noise synth and narrow roofing filters in my K3, I still couldn’t operate closer than around 20 KHz of him. Whether that was key clicks, synth noise, etc. I really don’t know.

I guess the manufacturers are heading down the SDR route as it is more than adequate for nearly every situation, whether we agree or not.

As I said before, SDR is not synonymous with Direct Sampling. The current implementations of direct sampling are more of benefit to the manufacturer than they are to the end user - it virtually eliminates alignment on the production line - and what alignment is necessary can be automated.

The block diagram does not show a superhet with any IF.
It shows att-bpf-rf amp-divider-14 bit A/D converters-fpga-D/A converter-audio amp.
The display has its own segment after the divider.

14 bit direct sample radio is going to be about the same as the 7300 which is a 14 bit I think.
So its a 7300.
What is different is two A/D converters (14 bit) being combined in the FPGA.
Unsure what that is doing....is two 14 bit units equal a 28 bit converter??

The user interface is likely much worse then the 7300 and the audio fidelity better.
Not a good thing for most users.

Look at the 2nd page of the catalog...

The user manual is available from today on the Yaesu official site.

I don't think that clarifies things much - no block diagram and the specification still says "direct sampling superhet" with an IF of "18kHz". The rest of the manual seems to be a quick hack job on the FTdx10 manual and still includes references to "IF".

Comparing the spec's on the 101, 10 and 710, the 710 is below the 10 which is below the 101 radios per Yaesu.
As you would expect from a 14 bit direct sample radio.
The 18 KHz might be what the dsp operates at?

Anyway, Yaesu says its not as good as the FTdx-10.
So what is the point of the radio at the initial price?
The 10 is the same price, its bigger, has a bigger screen, and performs better.

I thought it was supposed to be under $1000.00....

I would tend to agree - it seems like a strange marketing strategy. The FTdx10 is a magnificent radio with performance very close to either receiver of the FTdx101D - why is Yaesu competing with itself?

Apart from the price, which are the parameters you used to perform this ranking?

I am not questioning your conclusions, I'd like to understand more since I am quite novice to the subject: although licensed 30 years ago it would be my first HF rig (excluding the FT-818 I bought for unique portability, not wondering that much about it's actual receiving or transmitting performances)

The ones Yaesu is saying.
If you look at their web site and look at the info for each radio, they list various specs.
The 710:
RMDR +113
BDR +127
IMDR +102

The same things are higher on the 10 and higher still on the 101.

So Yaesu says the 710 is not as good as the 10.

Hard to tell where it will be on the Sherwood list, but below the 10 for sure.
