Well, may I ask why you are switching to the 7300?

That said, I, too, have spent HOURS (and DAYS) adjusting my FTdx101D transmit audio settings. Like Tim, I run the AMC at 40 and crank the mic gain higher to compensate. Otherwise my signal causes interference on adjacent frequencies. I saw it on numerous remote SDR spectrum scopes. I love my Yaesu but why they made the mic adjustments so convoluted is beyond me.

Anyway, count me in on as part of the AMC 40 club.

I could clearly see when I set my AMC to "higher" levels (less restrictive), my signal quickly got dirty looking on the scope. And of course, others verified it. I could see and hear the issues on various SDR sites. 

I admit, AMC of 40 is probably almost on the verge of "overkill", and anymore than 40, I couldn't get good strong audio out and my power would drop. 40 is about as "extreme" as you can go, at least on my Heil PR40, Heil PR781 and Yaesu MD 100 mics. And again, to get the SAME power and audio levels out, once I went to the more restrictive setting of 40 on AMC, I had to go WAY up on mic gain....all the way up to 70. Playing for hours with AMC, mic gain, Processor,  etc...while looking on my scope and listening to the monitor...and looking on my second receiver and SDR sites, it became obvious the interaction of the AMC and mic gain settings. Adjust one, you have to readjust the other. 

When I first got the radio, like others, I mistakenly ran AMC at high levels.... like 70 and even 80. Oh, I got many of the usual "your audio sounds good" reports. But the more critical people, who knew what to listen and look for, ALL told me I had splatter....products...whiskers.....  Yes, my audio sounded "good" to the average ear....but my signal wasn't clean and good sound people listening with good headphones (like the Sony MDR-7506) could also hear the little things audio buffs look for....like tearing in the higher freqs....or mudiness from issues around 150-200 Hz. 

Anyway, it took MONTHS to come up with the settings I finally settled on. Along the way, there were a mix of "you sound fine" and "you've got issues". I think most Hams say "you sound fine", because they either don't hear that well (after all, the General Ham population is quite a bit older, you know!).....don't want to offend, or just plain don't care. It's like someone you meet on the street and you say "how are you doing?" and they respond with "I'm fine, thanks". Almost no one says "well, now that you asked....actually.....things are pretty darn lousy for me". It's just a "reflex" response. How's my audio? eh..........it's fine...........

Bottom line....go on 7.168....find one of the Engineers on.....or better....a couple of them. Let them analyze your audio. If you come out with flying colors, you must be doing something right. If they give you a critical report and you don't like it, don't say I didn't warn you. Or, if you're ok with "communication grade audio", and of course, there is NOTHING WRONG with wanting just that....communication grade, then go for that and be happy. I wanted GOOD audio ....the best I could get from the radio without adding a bunch of outboard gear....and audio that BOTH sounds pleasing in ragchew, and JUST AS IMPORTANT (because I'm an avid DXer with 321 countries)....I want good audio that will bust the pileups. I'm a believer in you don't have to have that "shrill" sounding audio some seek ....to bust the pileups. But you sure don't want muddy, bassy sounding audio either....the DX won't hear that in a pileup!

I'll admit, I've had MANY radios. I'm a practicing, degreed Engineer with a very technical background. And this radio took a LOT more effort to get the audio GOOD.....good to MY perfection, than ANY radio I've owned before. And I know why that is. It's the AMC "feature". It makes getting the audio RIGHT, far harder. But once I got it to perfection, I'm very pleased with the audio and in fact, everything about this radio. Sure, it would be nice if the AMC feature and adjustment was better documented. And it would be nice if it was a bit easier to achieve audio "perfection". But now that I have it mastered, I no longer have any issues with anything about the audio on this rig. The internal EQ is superior to the UR6QW 8 band EQ I bought to test. The audio....with any number of good mics, is EXREMELY pleasing to the ear. And likewise, I'm still busting pileups with ease (but that's NOT all audio, it's also having a good station....good antennas, good operating technique, etc, etc). 

The 101 is a keeper. Harder to master SOME of the settings....but well worth every penny spent on it. I've got my "nirvana" radio. Now I can spend more time and money growing my "antenna farm".

Hi Tim – and everyone else.

 

Was listening to you on 7.168 on the LORAN QSO.

 

I too ran into some of the same “ that can’t be right” questions out of the box--- till I read up on the AMC, and what they were trying to accomplish. I too see the same “odd” response out of the comp with the PROC=off.. Appreciate the sharing amongst the FTDC101D users.

 

 

Tim –

If I can ask in the >Operation Setting >TX Audio params, which setting have you highlighted for:

PROC LEVEL – COMP or AMC?

AMC RELEASE TIME – FAST, MID or SLOW?

 

In > RADIO SETTING >MODE SSB, which setting have you highlighted for:

SSB MODE SOURCE – MIC or REAR?

REAR SELECT – DATA or USB

RPORT GAIN – xx?

 

Id ask what you have set for the PRMtrc setting and the  P PRMtrc too – but that might be the next question

 

Many Thanks!

 

Tom, K2TC

Re: FW 202104A & PROC ON / OFF ?!?

Barry D. Jacobson
 

Hi Tim, curious what tests you did to arrive at your settings. In previous threads, people have been unsure what AMC does. Seems consensus is like an AGC circuit to prevent peak clipping.

Incidentally, I had been wondering if there was a way to set mike gain scientifically using an AF trapezoid like some scopes can do, to check linearity. (More commonly they do RF trapezoid where exciter is on horiz and amp on vert.) But for AF trapezoid would need audio input and also audio output before modulation or after demodulation. I don't think the FTDX101 provides access to those on rear panel.

Re: Rx audio crashes with DNF

Denny WB8K
 

Yes, RFG control is necessary with AGC=off otherwise there can be a large amount of distortion. Unfortunately when trying to optimize best s/n on a weak signal AGC= off and adjusting the RFG works better than AGC=on. The only problem with this is a loud static crash or a very loud signal can distort desired signal.  However this is not what I am concerned with. I just happened to note that with DNF= on and AGC=off the RX audio crashes wit a loud noise and then the radio must be reset to return to normal. This only happens with DNF=ON.
So far I have not found much benefit to using DNF so for now I leave it off.

Denny - WB8K


Re: FW 202104A & PROC ON / OFF ?!?

K4TK
 

like was mentioned by others on here, part of it depends on your AMC setting. I have my AMC set very "restrictive", as in a 40. That gives me VERY clean TX signal....but also means I have to turn up my mic gain to about a 70....or I get reduced audio and reduced power out. Anyway, with the AMC set at 40 like I do, I run PROC on....and a low setting of 15. STILL, my Comp meter has deflection from 5 to 10, which is within the limits prescribed by the manual. HOWEVER, if I turn PROC OFF....and it's ALWAYS BEEN THIS WAY....for over a year now.....I get EXTREMELY high COMP meter readings. Yep, I'll get almost FULL SCALE COMP meter readings....IF....I turn PROC off. So I always run PROC on....and with that, and with my settings/adjustments, I get proper COMP meter readings. 

So that odd "anomaly" has always been that way, long before this recent FW upgrade.

Re: Yaesu XF-128SN SSB filter

33 73s
 

Hell Michael,

It is strange that this very basic filter is specified at 1.2KHz from BP ...
I had bought one that I had measured and of course opened to find out ...
Nb. When using this filter, the SSB remains perfectly audible ... you will only need to play with the bandwidth in the processing.
In some cases this 1.2K filter might help a bit.

For optimum results, it is in my opinion preferable to have real steep-sided filters carried out by a serious manufacturer in the useful bandwidths!
This would further improve the performance of your 101 during big contests with overlapping muscular signals.
(Shame that our current manufacturers for OM transceivers do not produce any to my knowledge ...).

If you do not used your 101D in big contests, with big antennas on a busy site multibands, etc ..., even a 101D well exploited in its basic version (without 1K2), will already offer you excellent performances.

They use frequency's just out side of the US Amateur Bands, the MARS mod removes the out of band TX limit, and allows TX everywhere. Some want this for better operational control on 60m, some want it for 11m, some just because its there, very few really need this for its intended purpose of MARS operation.  I enabled the MARS mod on mine and once my new SteppIR is up, I will be using this for MARS op.

Re: Rx audio crashes with DNF

Seems like we're talking about two different things, the beneficial used of the RF Gain control and the rig locking up. The rig shouldn't lock up no matter, so that's a bug.  In my experimentation, AGC off too much RFG caused very bad distortion, but it never locked up, but IDK if that was done in conjunction with DNR level 1, which distorted on big CW sigs irrespective.

Turning down RFG also decreases the slope of the AGC, so in my experience turning it off may not be helpful anyway if you first turn down RFG. Generally, I listen to the band noise, and turn down RFG, turn on IPO and/or add attenuation if it's much bigger than the noise floor of the rig as heard with the antenna switched off.  IPO and atten work similarly in reducing the level of noise the RX has to deal with.  RFG then affects how it deals with what's there sig and noise wise.

You can get good idea of what it will sound like by selecting the 3kHz filter and turning the WIDTH control to 1200 Hz.   That sets the width if the IF DSP filter at 1200 which has steeper skirts that the roofing filter so determines the width that you hear.  What the 1.2 kHz roofing filter will do is increase ultimate rejection of very big adjacent signals that would intrude between the skirts of the 3kHz filter and the 1.2kHz IF DSP filter.   On these rigs, when you select a roofing filter, the IF DSP filter is by default set to the same width.  For example, select the 3kHz filter, listen for a bit, then turn the WIDTH knob to 4kHz. You'll hear the bandwidth open up somewhat due the less steep skirts of the roofing filter.

You will increase the resistance of strong sigs in particular condition (contest / pile up).
If you never have problem when there is strong sigs (in the case of classical antenna
no very efficient) so no need to buy.

I've seen that behaviour with the previous Fw too.
It was always like that. Not a new thing.

Asunto: [FTDX101D] FW 202104A & PROC ON / OFF ?!?
 
FW 202104A PROC ON / OFF?!?
 
I did this test, easy to replicate:
 
1. Smeter1> COMP
2. PROC OFF 
3. TX AUDIO (SSB)
 
The COMP volume on the Smeter hardly ever changes, it is always high.
Even going to zero I always have a high compression factor ...
Even if PROC OFF the COMP goes to full scale!

I also tried without AMC by adjusting MIC GAIN etc ... having the controls easy to adjust via CAT.

I don't think he did this in the first FW ...
there is something wrong with it, either the PROC / COMP or the COMP smeter.

But I don't want to reload the old fw because I just did it today to verify that in 202104A the DB9/RS232c of the FTDX101 DOESN'T WORK CORRECTLY anymore but only checked for "simple sniffing" of the FA for PA, ATU or Dinamica ANTENNA

Do you also notice this anomalous Smeter/comp reading on this latest FW?

Re: Rx audio crashes with DNF

AGC OFF depending the signal + noise floor, this is possible to overload the SDR receiver and going to a lock-up situation not able to calculate. To be careful

AGC OFF only for very weak signals detection like below S-0  in CW mode. I did it for few occasions on 160 m with narrow APF with BOG + preamp.
