Try a program called VSPE or Virtual Serial Port Emulator and choose splitter. Then select COM20 as your virtual port and make sure you set a common baud rate. Then set the same baud rate for CAT and control in the other 2 options whilst ensuring the baud rate is correct.

De Spence G5STO

VSPE is free and give prompts after 30 days to register but it doesn’t stop functioning just doesn’t allow you to save the settings until you register.

Hello Greg,

I am curious with the Signal Link keying the radio via VOX generated PTT also.
As the SL has nothing to do with the CAT then the AFSK software should work via VOX setting and not comm port PTT. With this black sheep radio from Yaesu there is no telling.

Maybe John "AB0VX"can run a couple test to see with his 847 and Signal Link.

I will be ordering me a SL and module for my 847 in next few day's.

I tried using the Easy Digi by KF5INZ as I used them on other rigs and had a spare here. I could never get it to pass audio trying to trigger PTT from the current on the TX audio line from pc to 847. It would work if I used a second serial port on pc to key PTT on the Easy Digi. I just did not want to have to tie up 2 com ports on pc to 1 for CAT and 1 for PTT. I could make it work if I built my own Null modem cable from PC to 847 and pull the wires for DTR/RTS from same com port to interface board.

Re: FT-847 Digital Modes

I think you must be right, that the SignaLink's internal VOX-generated PTT is what is triggering the 847 via the Data connector.? Changing the PTT Method to VOX in WSJT-X would confirm this.? Apparently, when both Data PTT and CAT PTT are present, the Data port wins.?

That said, I was able to *barely* use the Data port's audio with PTT coming from CAT.? The muting of the Data port's audio isn't perfect, so if you feed a strong (speaker-level) audio into it, a little sneaks through.? I doubt this was what they had in mind.? No idea how close I came to damaging the rig by doing so, but it was worth a multiplier one Field Day some years ago...? :)

Hi John,

Thanks for the info.

Using your SignalLink with the SLCAB847 is 1 way I was looking at going. With the SL you also need the jumper module SLMODHT correct?
And from what I understand is the jumper module is what controls the CAT on the DATA In/Out port on rig. So if that is case should not need CAT enabled in either WSJT-X or DMR780 for rtty/psk. Or am I just overthinking this to much?

?Now that really sparks my interest as SL says the SLCAB847 will only work on HF and has to use front mic for UHF/VHF.
I also sent you an email from qrz email address.

Re: FT-847 Digital Modes

 

Greetings,

My FT-847 is connected to a SignaLink USB via a SignaLink?SLCAB847 cable plugged into the Data IN/Out jack on the rear of the radio.? I run WSJT-X with CAT control for the PTT and frequency control.? On HF and 6m I?regularly operate using?FT-8, FT-4, and WSPR and it works good for me.? On 2m and 70cm I've run WSPR with the same hardware and it works just as well as it does on HF.? This morning, I tested it on both 2m and 70cm using FT-8 and the CAT control changes frequency's and controls the radio's PTT as expected.

I've also used the same hardware configuration with JS8Call, which is based on WSJT-X.? It works as expected with CAT control for frequency selection and PTT.? I tested JS8Call on 2m this morning and the radio transmitted using CAT PTT.

Attached my WSJT-X configuration screen for the above hardware configuration.? I happen to use 9600 baud instead of 4800 baud which is the default.? I've used 4800 baud in the past and it works just fine.? Keep in mind that that some early FT-847's may only support unidirectional data on the CAT port.

Re: Digirig with FT847?

 

I've used the Digirig on both the DATA and 6 pin DIN ports on the FT-847.? It worked very well in both cases.?


Re: FT-847 Digital Modes

 

Hello All,

Well that makes sense as to why it was not passing audio back to radio as PTT was being handled via CAT like all my other rigs.

Does not make sense why Yaesu done it that way except that it mutes the mic or suppose to on the 847. I will add the cap and the resistor into the interface
line to see if that takes care of the problem.

Thanks All
Tim


Re: FT-847 Digital Modes

As Stu notes, the challenge with using the 847 with the digital modes is that the source of PTT needs to be the same as the source of the audio, EXCEPT for CAT.? CAT control of PTT for some reason that continues to baffle me uses audio from the mike jack in the front of the radio.? I have yet to figure out a use for PTT via CAT.

HF modes use the data jack and the PTT circuit, VHF/UHF packet uses the DIN and the separate PTT pin, so if you have one sound card for both modes it becomes an interesting challenge in building a cable with the right connectors (and DC-blocking) to do both.

Hello All,

Before I shell out the $$$ for a SCU-17 or SignalLink I have a couple questions.

When using the Data IN/OUT port on back of rig do you need to also wired in the PTT circuit shown on page 19 of the User Manual.
I ask because my logging and digital modes software will key radio via CAT.

Or is it mandatory that when using HF Data Port PTT has to be controlled via the Data Port.

I would like to use the radio on VHF/UHF data modes also and I know that going to be on the mini din.

I went thru my spare parts box today and tried to wire up the Easy Digi interface to see how the radio would do on some HF FT-8. I had audio from rig to pc no problem along with PTT from HRD CAT or WSJT-X. I just could not get audio from the pc back into radio and Tx the audio. It would key radio but showed no output power on radio meter,In line power meter.


Re: FT-847 Digital Modes

 

According to some notes I copied from one of the forums (either VarAC or VARA).......here is what was said.? I'm sorry I didn't make a note of the source it came from.? VarAC is typically done on HF.


--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Congratulations, your latest VarAC 3.7.9 with 847 rig now can handle the ft847 with PTT over RTS or CTS and CAT over serial-com.

Here the specific ft847 requirements as I have it working:

1.? PTT and modulation must be on the same connector with ptt over RTS or CTS, and NOT ptt over cat

2.? The PKT connector is ONLY for FM. The Data-In-Out connector is ONLY for all except FM, usually SSB. VaraHF uses Data-In-Out.

3.? The circuit diagram in Yaesu-manual-(my page 16) has a wrong capacitor with 10uF in "afsk-out". I must use 0.47uF. With 10uF my ptt switches too slowly.

Re: FT-847 Digital Modes

 

Depending on which brand of sound card interface you get dictates if it keys the radio via VOX or using CAT.? ?I have a SignaLink which uses VOX on the DATA in/out port for HF on the rear panel of the FT-847.? To the best of my knowledge, I do not believe that the SignaLink can use CAT for it's HF PTT operation.? You can look on their website to see what it supports for the FT-847.? That all being said, the HF digital works as expected on mine.?

You are correct in that if you intend on using the VHF/UHF FM data modes, it will be via the 6 pin DIN connector.??

Re: Molex plug for FT847 power.

 

Hello Jim

The Molex 39-03-6064 was a bust. The pitch is 6.7mm as the rig's pitch is 6.0mm

I did manage to crimp the crap connector female pins with a .100" crimper and they now fit nicely in the stock rig connector.
Took the new gold plated female's and used the crap housing and now the rig doesn't cut out when you wiggle the power
plug. By the way the crap connector's female pins are the same as what I received today (to big in diameter).

Not sure what to tell you on finding a male connector like what's in the rig as they seem to be allusive.

Hello Micky.

I cheat.? I go to our local Hobby Town and get a piece of K&S brass tubing that just fits over the end of the male or female pin I want to remove and slide it down so it pushes the barbs down and the pin can be removed.

Thank you.

Hello Pat.

I need the socket that mates with the power cord end (or same as socket on the back of the radio) so I can make an adapter cable to try and fix an Icom that uses a 4 pin Molex!? Not sure why they used 4 pin on them when most YaeCommWood rigs of that era all used the 6 pin plug!? I did not want to chop the one off the cord on the power supply since I still need it to power the FT840 and FT847.

Thank you.
