Great video Scott! Very informative. I just purchased an FTDX-10 so I am watching RUclips videos to speed up my learning curve. Merry Christmas and Happy New Year! Paul WQ4A
The Icom bandpass filter is set to 300Hz (FIL3), not 500Hz like the Yaesu. Half of the video the Icom has the squelch closed, and it is clearly seen that you have the Icom Noise Reduction very high, to the maximum, in CW it is not recommended to exceed NR=3-4. The Yaesu AGC is in AUTO, and the ICOM is in FAST, this also influences the result, which should be practically identical, because the distance that separates these two transceivers in the Sherwood list is not possible to appreciate with the human ear. Greetings
Tnx for watching! The Yaesu roofing filter and the Icom BPF were set to 500 hz. Both DSP filters were set to 300 Hz. Both DNR's were set to 15 (yes, I turned down the DNR on the Icom). At the end of the day, I agree with you that whatever is heard on one can be heard on the other. Cheers.
Ftdx10 is a much better cw rig - quieter receiver and 10x better noise reduction- has apf which the 7300 does not have… not even close with weak signals. With weak signals the 7300 does not keep up. In tight conditions the dx10 way more selective. I had the dx10 and it compares favorably to an ftdx5000mp and ftdx101mp. I’d recommend you check out videos from N4HNH for tips on how to run your dx10 to get the most out of it ,but keep having fun in the process! Oh BTW dx10 much preferred on SSB as well with- superior NR and more audio tailoring- built in 3 band rx eq! Even the 101 does not have the rx eq. Icom not bad but dx10 excellent.
Do you have a FTDX10? Do you have an IC-7300? Having both, side by side using the same antenna during the CQWW DX CW contest, any station I can work one, I can work with the other regardless of the signal density. I do agree that the receiver on the FTDX10 is quieter, but the noise floor on the IC-7300 is 4 times lower, in other words, it hears better. Yes, the FTDX10 makes a nice CW rig, but with its other shortcomings, If I could only have one radio, it would still be the IC-7300. I write about the FTDX10 on my blog KK4Z.com.
Yes sir, I’ve owned both and ran them side by side. Nothing wrong with a 7300- overall incredible value. I just think the dx10 is quite a bit better for weak signal cw and I prefer the way the SSB audio sounds when processed on the dx10. Weak signal RX on my DX10 compared favorably to my ftdx5000- I find that remarkable!
@@neoretrophoto9198 Tnx for the reply. Your first comment didn't sound like you owned either one. I find that with weak signal/high-density signals I can work them with either radio equally well. I think the differences are more of nuances between the two. The FTDX10 is a little cleaner sounding. I am keeping the FTDX10 for a while, to give a good long-term test and review.
I sold my DX10 and kept the 590SG and 7300. Both superior IMHO. Too many silly little niggles with the DX10, I'm happy to see the back of it after 12 months.
I agree 100%, the 7300 is not even in the same class, I can hear weak signals on the FTdx-10 that I cannot hear on the 7300. The filters and noise reduction is also way better on the 10. I am 100% CW DX'er and contester so this matters to me. I would never consider using my 7300 in a contest but the FTdx-10 works well for contesting. My 7300 has been relegated to casual rag chewing now.
That is correct. Roofing = BPF. In reality, the audio on RUclips is not the best and the only real way to discern audio is actual on-the-air listening. The CPU between the earfuls has an amazing DSP unit. I still have both radios and I still feel the same way.
@@KK4Z but a BPF is not a roofing filter. The roofing filter is the filter through which the first IF must pass. the BPF you see is in the DSP filtering itse;f, not before that stage. My roofing filters in one of the rigs are in the 700 MHz range and definitely before it's entering the DSP. You cannot compare them. You could compare if you would have put the lower and upper freq of the DSP filters on both rigs at the same values and not engage the roofing filter. I say yes to the ears as a ood DSP, but youtube streams very good audio and now I cannot even closely think of what is what as I don't hear them at the same time. Also, the bw used on both means that there is no reason to have it high quality at all. I did this between mcHF, and ICF 7600 Sony radio, malachite and a 7300. left right. the malachite ended up as the worst, even while the group told everybody that it's the best receiver. Just left right, same freq makes it worth. (I also have heard elecraft vs icom, also left/right... interesting resolts there.)
@@RoelandJansen But. An SDR radio does not have a IF stage. The band pass filter is before the preamp and the ADC. With the Icoms, when the DSP filters are set below 500 Hz the BPF function kicks in making the skirts sharper than the normal sharp shape, pretty close to what a roofing filter will do. If you have a 7300, bring up the filter screen and when you dial a DSP filter to 500 Hz or below, you will see a BPF icon light up. Icom is pretty quiet about this feature. It also does this on the 7610. It works quite well. Please remember, this is not an overly technical channel. I present a users view. I take them out, I use them and I give my opinion about them. I read the manuals lightly like most people do. There are plenty of other channels that take deep dives. But thanks for stopping by and thanks for your input.
I really find them quite similar. My hearing is not as good as it used to be. However, in an HF radio, I am not looking for audiophile quality. Each radio hears the same signal about the same. This is a rather subjective point. Your ears are probably very different than mine and your tastes are also probably different. No right or wrong here.
How you can decently compare receivers with the DNR in the circuit is a mistery to me. I'm always surprized how difficult it seems to be to operate a receiver.
Hello Bruno. This is not a technical review but more from an operator perspective. I took both radios and set them up as an operator might and then compared them. If you are after the technical nitty-gritty, visit Rob Sherwood's Receiver Test Data page. Hope that helps.
At the beginning the 7300 had the squelch on, so the reception was degraded. Very similar receptions because clicks and phase noise of CW signals don't allow to hear the better results of the 10 measured in laboratory. The 7300 is general coverage when the 10 is not because its IF is inside the HF spectrum and the 7300 is not plagued with images rejection problems. 7300 is modern technology when 10 is sixties technology.
The squelch acts as a high-pass filter. The little that was on did not affect the signals received. Yes, the architecture of the receivers is different. The Icom actually has a lower noise floor than the Yaesu. The Icom is more "open" and the RF Gain is your friend.
Hi, thanks for your comments. The squelch doesn't act as a high pass filter, but as a switch. Under a certain level fixed by the double duty SQ/RF control the switch is Off and the reception is blocked. Over this level the switch is On and the receiver is open. If the signal is not stable, as are HF SSB signals the switch is not stable and reception is chopped. Squelch is more effective with constant carriers like FM. Best regards, Georges F6DFZ
The thing I can’t figure out is if the direct sampling rx is more modern and presumably better then why is Elecraft’s highest performing K4 going to have a hybrid architecture like the dx10?. I guess it’s that 1960’s secret sauce?
@@neoretrophoto9198 Hi, the low cost FT-710 direct sampling receiver has better figures than the high cost down conversion K3S on the Sherwood chart. The only advantage to down conversion receiver is field day or contest station when multiple station are close by. The only argument for down conversion, out of these points, is to be high in the Sherwood chart. What folks don't seems to understand is that a receiver cannot be judged on only one criteria. If the ranking on the Sherwood chart, was done on the image rejection, for example, there will be no FTDX101, FTDX10, TS890...
@@f6dfzgeorges196 yes good point I’d prob buy a 710 over a 7300 in 2022/23 for what I believe would be better signal processing regardless of the architecture- but haven’t ran one. DSP comment is based on actual use of DX10, 101, and fr5000. Have you ran an 890, 101 or dx10- forget the chart try one. The 60s are the golden years hi hi - 73 OM

Tnx for your feedback. You really can't go wrong with a 7300. It still stands as "If I could only have one" radio.
Wow fantastic radios 73 from kb2uew
