High swr modification/fix failed

Justin <2E0EUG@...>

Hi everyone, so I got my radio back last week after it went for repair to fix issued by Yaesu the high swr when using the tuner, unfortunately it has not completely fixed the problem, it is not longer doing it on the lower bands but the issue still remains on 10 meters, I am awaiting a call from the shop to see what happens next, I am wondering if the radio has an undiagnosed fault or whether the fix issued is not a complete solution, any advice from the forum and fellow hams would be greatly appreciated.

Lou, I was not aware of that function being disabled. I wonder why Yaesu has thought to do this?  - Mike

Subject: [FTDX101D] No RIT (RX CLAR) on 60m :-(

 

Been making some Qs on 60m and one thing I find odd is that RX CLAR (RIT) is disabled when using the 5 CW and 5 USB preprogrammed channels.  I was working an op on 60m cw and his tx freq drifted down maybe 150-200 Hz...still within the channel and I would have liked to be able to use RIT to keep him centered in the narrow filters I was using due to the amount of band noise I typically experience on 60.  As it was, I used the shift control to keep the filters on him, but the pitch was getting rather high.  I understand they program fixed channels and disable TX CLAR (XIT) to prevent accidentally straying from the freqs, but I can see no reason for RX CLAR (RIT) to be disabled.

Re: FTDX101MP overshoot

Barry D. Jacobson
 

Has anybody used a Kenwood SM-220 monitor scope to look at transmit waveforms? My monitor blanks out every time the rig relay seems to switch and then recovers about a second or two later. I tried two separate Kenwood monitor units of same type and it happens on both, with or without my Heathkit SB-220 amp on or off. I have changed the attenuator settings and triggering freqs on scope but nothing really helps.

Don't know if this is overshoot or just bad transient response in these scopes' design. Maybe bad capacitors in these older scopes. But my lower power HP 3336c signal generator makes beautiful sine waves on the monitor scopes.

Any ideas. Maybe will take a video and try to post here later on.

>>>It doesn't seem to remember anything about the previous tunes that it's done, on the same antenna and frequency range, even though it gets the SWR below 2:1<<<

If the SWR is greater than 2:1 with the tuner off, it won't remember the tune irrespective of what the resultant SWR is with the tuner on.  example:  If the SWR the radio sees is 2.2:1 with the tuner off, and the tuner then tunes it to 1:1, it won't remember it.  The SWR is still 2.2:1 at the antenna connector at the back of the radio. 


Re: RF CONTROL

Lou W7HV
 

Yeah.  I suspect some of these artifacts are due to the IF DSP being in the AGC loop and there being some latency in it responding to control inputs.  It's there, but I hasn't affected operation or performance in my use. 


Re: Mouse Control

Lou W7HV
 

Having tried my M310 for a few days, I find I don't have much use for it. The mouse only does the same thing as touching the screen and nothing more. I still have to use the buttons and knobs on the radio the same as without the mouse, so I find it easier and simpler to touch the screen while I'm at it rather than grab the mouse instead.  Perhaps for some situations or individuals, the mouse would be preferable to touching the screen.

I was expecting more, but it is what it is.  It would be nice if the mouse had greater utility like being able to scroll and make numeric entries, drag the cursors in the spectrum display, tune the VFO, change bands, etc. but that would be way down at the bottom of the list of needs/wants as far as software updates go. Certainly those things can be done using appropriate software on a computer hooked to the radio.


BCD code for 60M band

I am programming my arduino automatic antenna selector and I need this code.
Is anyone know what is the BCD code for 60M band on FTDX101D?
Thank you,

Re: RF CONTROL

My 101MP has this problem. It's AGC related. With a moderate strength signal (on AGC threshold) try switching AGC off and swing the RF gain up and down. On my set the gain swings smoothly with no trace of the "dirty pot" effect. Switch in the AGC and it's there. It seems like the AGC system is playing catch up with the system gain.

When the tune light is on, and I hold the button for one second, I hear the wheels turning and then stop.

I thought that the correct settings would then be “memorized” and returned to after one QSYs and comes back to the original frequency later, as do many external automatic antenna tuners.

However, I never hear the tuner in action again on transmit, unless I initiate it.

To test this, and because I have a SteppIR on autotrack, I thought that perhaps the SWR would be low enough already so that the antenna tuner on the MP would not need to do anything further.  Just to make sure, with the autotrack on I then tuned the MP to the already tuned SteppIR antenna and I heard the wheels turn.  I am not sure that means anything, but I wanted to make sure that the MP itself was tuned to the frequency via the internal tuner.

Now turning the autotrack off, if I QSY to another band where I had already tuned the MP, I thought I should hear the tuner come into action when I initiate a transmission into a purposely mistuned SteppIR antenna.  However, I do not.

The manual refers to a "momentary" press which should turn the tuner on, and a press and "hold" to begin the tuning process.

My experiment above was done with the antenna tuner light on, and theoretically in the circuit.

What behavior should I expect from the antenna tuner on the MP, or what am I doing wrong?

Or is there a problem with the tuner?
I've noticed this on my 101D as well. It doesn't seem to remember anything about the previous tunes that it's done, on the same antenna and frequency range, even though it gets the SWR below 2:1.

push tuner button and hold down fo 3 seconds it will  beep 3 times take finger off let tuner tune when done it will stop and red light will be on .If your antenna is more than 3 to 1 swr it will not tune the tune range is limited to 3 to 1

Hi,
The auto tuner it's for make 50ohm image to your final unit view.
If you use the SteppIR who send this 50ohm information to transceiver, your auto tuner don't have to make something. 50ohm view is correct for it.

What is your previous transceiver and what do you don't understand on antenna line ?

Re: Auto Antenna Tuner - MP

Lou W7HV
 

Page 57 on the US manual states the ATU only remembers tunes that are below 2:1, and for each 10kHz segment.  If the load is greater than 2:1, then you must tune again.  I haven't exhaustively tested this, but that does to be how it works. When switching between memorized tunes, there's very little fuss as only the few necessary relays simultaneously click, unlike the 10 second cacophony that goes on when it's searching for a new tune.

The serial number for my MP is 1C220008.

My FTdx101D is for sale and since I still have it I checked it too. 
Its serial number  9G030181 and has the same version of firmware as my MP.
It shows no overshoot. I can post the pictures if needed.

Hello,                                                    March 1, 2021


I bought Yaesu FTdx101D 14 months ago. I like it so much I bought an FTdx101MP about a month ago.


I tested the MP for overshot on the first CW character.  I used a Tektronix TDS2012B oscilloscope. The radio is connected to a dummy load. I put a T connector in the cable so I could capture the signal on the scope.


I took four pictures on my cell phone and posted the pictures to QSL net. The trace show no overshoot.


Here are the locations of the pictures.
