Hi
I would suggest you to download Yaesu Ftdx101 literature from files including the block diagram from their site and you will get all your answers.
About audio performance this is all about processor power bits.

Hi N2YWL.... " I'm looking to see if I can using any of these applications to manage and view the ftdx101d receiver using this application spectrum scope? "

Exactly what applications are you referring to?  You do not indicate their names???
Also what Operating System(s) are you planning on using?  MACOS?, Windows, Linux etc?

Re: optimum dnr setting

W0ARM - Alan
 

Not sure there is such thing as an "optimum" DNR setting.  It would all depend upon YOUR conditions, noise levels, signal strengths, etc.  I adjust mine quite often, depending upon conditions at the moment...

You can quickly set or adjust the DNR "level" at any time, on each VFO separately, by simply long-pressing (about 2 seconds) the [desired] DNR button, until the DNR setting pops-up on screen. Then use the "MULTI" knob to set/adjust to your desired setting.  The pop-up will disappear after about 5 seconds.  Same procedure works for the noise blanker also... Long press the NB button, make adjustment as desired.

One thing to remember is, the DNR setting in not a "level" adjustment, but rather a selection of one of 14 different DNR algorithms (1 - 15).

I've found a DNR setting of 7-9 works great for me, although sometimes it's less, sometimes it's more...  Whatever's necessary to get a nice balance between atmospheric noise reduction and signal readability.  The DNR function was improved greatly after one of the firmware updates (don't remember which one).  They eliminated the "watery" distortion in the lower-numbered algorithms.

Lastly, having your LCUT and HCUT settings at "OFF" effectively makes your receiver audio wide-open, providing the widest "bass" and "treble" response.  With them in "OFF", the settings of the SLOPE adjustments are of no concern, and do nothing, since there are no frequencies selected.  Since there is really no need for "fidelity" in a received SSB signal, there's really no need to "hear" audio above ~3000 Hz, or below ~300 Hz, therefore you can cut the response using the HCUT & LCUT adjustments.

HDSDR or SDRplay or Win4yaseu

Hi Folks,

Please looking for help.  I'm looking to see if I can using any of these applications to manage and view the ftdx101d receiver using this application spectrum scope?  I'm not interested in using receive ports of a pan adaptor, but just this application.  Is there a way to connect a PC running any of these SDR applications via USB port , with out having to insert the physical pan adaptor box in the middle, between the radio?  I thought I saw a virtual adaptor available using just USB port in the radio to connect to a PC running HDSDR, for ICOM 7610?  I was wondering if there's something similar for FTDX101d, else this is a big limitation for this radio.

Cheers, N2YWL


RSPdx and 101D

Have  SDRplay RSPdx to connect to RX OUT (Main) on back of "D".

What experience does one have that can recommend which software works best?

The SDRplay or HDSDR, both using Omni-rig for control of 101D?

Any advice, tips appreciated.

Re: VC Tune

I forgot to add that by doing that it makes it so much quieter. Normally on any other radio I would turn on and hear the noise and shut it back off because I don't want to hear it. With the 101d and this trick I get to use the radio more..

I keep the radio on amp 1. It's just amazing how signals pop out of the garbage local and on the band.

SDR or Analog?

Barry D. Jacobson
 

While the FTDX101 is marketed as a hybrid SDR, I believe this refers to the band spectrum display. There are some  advantages to sound quality in analog receivers because the digitizing process creates a stair-step approximation to the signal, rather than a smooth curve. My understanding is that a complete SDR (direct digital synthesis, DDS) system would not require an IF at all, as all filtering can be done digitally, right off the digitized RF signal. Yet the FTDX101 has an IF, and the VC tune seems to be analog with actual variable capacitors controlled by a motor. On the other hand, some filtering seems to be done using DSP, like IF width, and various noise reduction processing. Can anybody explain the architecture and whether the main signal chain is analog or digital or some mix? If digital, how does received voice quality compare to older analog radios?

Thanks.

Re: Transmission bandwidth problem on all FTdx101 perhaps

Hi Ludovic,

 

Please, Can you let us know what have you seen on the bottom  end?

Is the bandwidth down to 50 or 100 Hz ?

 

Thank you

Subject: [FTDX101D] Transmission bandwidth problem on all FTdx101 perhaps

 

Hello,

look at the spectrum of the FTdx101 emission (on a websdr or other tranceiver
for example) and you will see that :

If you set 100-2900 or 50-3050 you will see that the sgnal
reached 3200 Hz or more...

There is no problem with other Yaesu like FTdx5000 , FT2000.

Can you verify this on your transceiver and give the serial number
if you have not this problem ?

In France, i see the problem on all FTdx101

that I met on the amateur radio bands.
 
Best regards,
Ludovic - F5PBG.

Yes, but how often is that really a problem with a radio with 107 dB of close-in dynamic range?

Don’t know about suggestions, but I do know it works, and I use it on 80 a lot. Watch the noise spikes move on the bandscope.

If VC Tune can improve S/N in the presence of QRN, the mechanism is a mystery to me. I suppose by attenuating everything it might have the same effect as backing off the RF gain, but I can't see anything else. Any suggestions?

I have used this radio from mid August til now. Still learning best settings for different modes.

The noise abatement, videos on YT VC) is reason I bought the D over all the other available rigs (7610/890s) whilst I wait for my K4D to arrive. Received alert my K4D arriving this next week to Florida. I will pick up before xmas...look fwd to A/B testing. My experience operating the D during CQWW cw contest from HO2T re-enforced belief in this rig under 'battle condx'. VC plus easy use of RIT when running pileup of guys who do not know not to zero beat plus use of XIT to beat big pileups on OX/OY/FK/3B8/5Z4/4L8/EY8/ZM were pleasure to operate. I REALLY do like this radio.

Re: VC Tune

Buddy Morgan
 

I agree, in run mode VC tune sometimes can be a big help. I probably use Shift more often than VC tune, to diminish interference from an adjacent station, who is also in run mode. I don't think I have ever used VC tune in S&P mode. As several people have said, all these features are tools in the toolbox. I wish I had had this radio, back in the 1970's!

I know not everyone who owns a 101 is a contester,  but VC tune helps for contesting. I have used it when I am running and get 4 or 5 stations calling me at the same time. I crank the VC tune to block the weak ones or many times just the less loud and work the loud ones and then open VC tune and work the weaker ones. It is just a tool that I have to use occasionally. It helps thin the pile so I can work them faster.
