:yes: :yes: :yes:
Does anyone else agree?
There should be some easy way to connect an automatic tuning amplifier such as the ACOM 2000A to have the frequency on the amplifier follow the transceiver.
No other SDR require the series of very complex steps to have the frequency communicated to an amplifier that uses CAT for tuning.
The difficult i am having is causing me to look for an alternative SDR.
This is the only downside to enjoying this wonderful transceiver.

Is there a software fix for this problem?
It actually is a big problem!

You just need to make a BCD cable that connects to the DB15 connector

Every rig is different

And there are guys using other Amps that work as well with the EESDR rigs that follow the radio
the EB series, I think there a few guys using the ACOM 700 and 1200 S as well

Nothing again ACOM, I have older A1000 love the amp works very well, its not auto anything, but it is damn reliable, just like my 2DX

the info is in the user addendum on page 23 Version 6.12 May 2021
4.3 BCD Interfacing for the Acom Range of Amplifiers

Its not difficult

Rick I agree 100 % ....

With combination ESDR, SDC phisical (USB or COM on MB) and virtual COM ports only the sky is the limit... You can make all devices folow RIG CAT. It is not big and complicated issue.
One cable with two leads from phisical COM port and ACOM will work with Kenwood protocol. You can add additional lead for PTT. You can use RTS or DTR signal.
My Expert 1K-FA is folowing the bands on SUNSDR2pro for 5 years now ... before SDC was introduced. But you have to read manuals and try different stuff. That what hamradio is all about.
There is no "plug and play" option here.

I am too lazy to change band and re-tune my amplifier. So I bought an automatic amplifier.

Is that interface cable sold anywhere?
If it not , maybe it should be sold as a kit with the other instructions.

Maybe, I should wait for that kit.

Thanks for the information

I am unable to find the user addendum.
Could someone post a link.
It is not under USER MANUALS!

I am already using the 15pin connector on the SDR2dx to key my ACOM amplifier with.

How can I use that same 15pin connector to build another cable for my ACOM amplifier to follow the frequency on the transceiver?

It might be more convenient for the author of this thread to contact the cable man for USA, KC5PCB Dan Tassell. He is the go to guy.

The UMA is at www.dropbox.com/s/lhvwwuyuxpoq7gs/Expert%20Electronics%20Addendum.pdf?dl=0 and section 4.3 covers BCD connection for Acom amplifiers. CAT via a serial port, real or USB type, is easier and covered in section 7.2

Sam,
You have a SunSDR2 DX yes?
Look at the product page for the DX model, then the tab saying 'Documentation' . It is all there..

I made the interface cable from the diagram supplied . One end plugs into my SDR2dx and the other end plugs into my ACOM2000A.amplifier.
Next I went and check all the boxes in the ExpertSDR2 software under the Ext Ctrl tab.
Nothing happens!
No band switching!
No frequency change!
I can't even key the amplifier because the cable that I use for keying is replaced by the new one I was instructed to make.

By the way, I can only access the User Addendum from the link provided.
I need for the process explained in a logical sequence.

II don't need any cables from England.
I can make my own!

How can I fit the both cable on the SUNSDR2dx since I need one to key the amplifier and another to send the frewquency change info?

Please try not to be sarcastic in your explanation

Thank You!

I built the cable using a break-out box
I plugged everything in.
What next?

I think I have made my point!

If the item had a USB port, people would not be asking questions about how to setup their auto-tuning amplifier.
By the way! According to ACOM Tech Support:

The BCD is useless for the 2000A, because the exact frequency is needed. Most of the bands are too wide and the amp has to know in which part of the band to tune up. It is same with the 700S when is equipped with an automatic tuner. Then it will not work with BCD too.

QED!

I do not believe SunSDR requires any USB.

Firstly, because it sounds it only needed to connect ACOM (which seems to be the center of universe). The problem that you cannot get provided port working with heaps of manuals does not make "need USB reason" any valid.

Secondly, because SunSDR already has FE port. And there are plenty of Ether-to-USB adapters on the market.

BTW, I do not mind if EE will move FE port to GE and even make additional GE-optical port - this would be handy.

Thank you for not asking for RS232, Sam.
