Re: FTdx101MP with Acom 1200S amp and 04AT tuner

See pictures, this is the FTDX3000 and the 101 port is the same, the manual for 101 is unclear. 
I have a 15pin cable from 3000 and tried it on the 101 and worked no problem, use Pin2 & Pin3.
I’d need to look in the manual to see what menu is the out adjustment

Hi Rick
The only solution I see right now will be to select AM mode that got its own RF power memory settings 25 or 50 w maximum (D or MP) or lower saved with mode control. There is no low power tune that I know unless someone else will comment that.
RS232 and USB Codec can be used at the same time. I am guessing but you should use a null RS232 cable (reversed pin 2-3) as other amplifier brands. Amplifier will follow the radio frequency.
To ask Acom group connected with a Yaesu radio seen your auto-tuner is linked with the Acom Amp.

Bonjour à tous

The amp 15pin you can ground 2 pins and will send a carrier which is adjustable power in the menus.

FTdx101MP with Acom 1200S amp and 04AT tuner

Rick Boswell
 

I currently run an IC-7610 along with an Acom 1200S amp and Acom 04AT tuner. There is a momentary pushbutton on the amp which initiates a TUNE cycle in which the amp sends a CAT command via a cable from the amp  RS232 CAT connector to the 7610 REMOTE jack on the 7610 to change xcvr mode to RTTY and keys the 7610 at a low power level (about 20 watts) to facilitate a tune. Once the tuner settings are determined, the settings are stored in the 04AT memory and used  when the 7610 is tuned to that frequency (actually a band of frequencies), and then the amp issues a CAT command to return the 7610 to the mode it was in prior to the TUNE cycle.  This makes for nicely automated operation without the need to use RF based sensing for tuning and the possibly multiple operator steps this entails.

 

I am considering adding an FTdx101MP to my station and am, so far, unable to determine from reviewing the 101MP manual if this transceiver can work in as integrated way as the 7610 does with the 1200S and 04AT. My best SWAG  is that a connection from the 101MP RS232C connector to the RS232 (CAT) connector on the 1200S may allow this provided the 101MP is supported by the 1200S/04AT firmware; DX Engineering appears to offer a xcvr to amp cable for this purpose (DXE-600S-YSU-5). Any guidance on this topic from those who may be using this combination (101MP +1200S+04AT)?

 Thanks,

Rick

Hi Alan,
I think you have a problem.
If I click on the link
Just open "unzip" it and SETUP it and it doesn't ask for any password or ID ...
 
it works immediately.
 
If you only need possibly to ENABLE or DISABLE your CTS/DTR on the FTDX101 but there must be absolutely no problems.
 
You probably have something wrong or we're talking about two different things ... I'm sorry but I don't understand.

Hi:
Just tested 1,2khz filter during the last CQWW, it works really good, the receiver comes very selective and help a lot to avoid the adjacent near signals, the DSP filters used at 2.0khz.
So, for heavy SSB contest in my opinion, helps a lot, but not usefull during light SSB contest or everyday use. 
Just my opinion. 
Regards to all and stay safe.

But for ssb it seems utterly useless. 

 

Some wider then 600 digital modes sticks me as the only possible use for it.

In my personal opinion, if you set the R.FIL to 600Hz or 3000Hz or if you move the 1200Hz to SSB only with WIDTH you can already have a personal confirmation ... (audio and BW)

It could only be used in RTTY or some other digital mode, but also in RTTY if 3k is not good, 600Hz is definitely better.

 

My opinion is that the price is not worth the little use that can be made of it:
for SSB it would be too tight and you would have to lower the SHIFT considerably to be able to understand the audio.

I would have understood a 1k8Hz for SSB but 1200 seems useless to my use.

Hi,

Yes it's strange this choice of BP roofings

* The first problem is that nobody seems to have produced intermediate filters, bandwidth between 1.8 to 2.3KHz ... and our usual manufacturers do not seem determined to produce us ... maybe Yaesu, but that would require an update firmware update !!! I think we can dream ...

* The second problem is that the optional CW and SSB filters have a recognition pin ...

Hence my question, would someone have the info of what is in these filters to allow their recognition?
Otherwise I will have the solution to pass one to the hotplate, to find out ...

My guess. A d a very eli5 explanation of this guess. 

The roofing filter has something like 30db attenuation out of its band. Increasing to that as you get further from the 1.2 head. 

So even though its 1,2 wide. Some weak signal will likely come through for a good 300 either side of that. 

This allows some weaker signal to be heard and cleaned up by the DSP functions in ge real. 


I really do want to gphear and see some video of this ispn use, I really cannot find any online. 

But if that seem to be what is happening. I may well have had my mind changed and will sometime send my radio back for the mod. Allow with a vct101. 

Sorta want to wait for a 2.0 one to be released by a 3rd party so I can have 1.2 on one reciever and 2 on a other. But I can't see that happening within the next year or so. With current events.

Re: filtre 1,2 khz

Yes this is odd, we cannot receiver wider than the first stage roofing filter. Down conversion receiver roofing filter near 9 mHz has a narrower skirt over old up conversion for the same roofing filter width.
This must sound bad for me,,,donald duck 
Also Ftdx101 series have a faster SDR and we can well copy at 1.5-1.8 kHz during extreme contest on ssb. Of course nothing could be done if the interference was inside our receiver frequency,,,
Seen we need to solder the filter, I would leave it alone,,,
73,
Rejean


Re: Found anamoly?

Rejean Leveille
 

Hi
AGC at off, this looks like you excided the maximum SDR converter signal, to be careful with that damaging some circuit. Lock-up is the last defense level,,,
AGC Off to be used with extreme low signals below your normal AGC SNR and the radio will stay at maximum amplification well below -145 dBm.
Example trying to copy a very weak cw signal with a receiving antenna and S-meter always stays at S-0, turning AGC at Off you may get 6 dB extra over SNR and enough to copy.
I was able to work 7Q7 on 160 m cw 2 days ago with this setup.

Salut Régis
I really think it's not worth it.
 
In my personal opinion, if you set the R.FIL to 600Hz or 3000Hz or if you move the 1200Hz to SSB only with WIDTH you can already have a personal confirmation ... (audio and BW)
It could only be used in RTTY or some other digital mode, but also in RTTY if 3k is not good, 600Hz is definitely better.
 
My opinion is that the price is not worth the little use that can be made of it:
for SSB it would be too tight and you would have to lower the SHIFT considerably to be able to understand the audio.
I would have understood a 1k8Hz for SSB but 1200 seems useless to my use.
