Dear Elmers,

A really, truly N00B question, here. (Calibration: My next digital TX will be my first; ever. This is new to me.)

Because I want to get into digital modes (RTTY, PSK31, etc.) using something like fldigi (in the process of being adopted by my local ARES group), I recently upgraded to an ICOM IC-7100.

At a recent Ham Convention, someone told me I did not need to use (something like) a SignalLink...as "...everything you need to operate digital modes is a feature of the IC-7100." This was news to me...but--many, many hours later (after RTM, Googling, YouTubing, QSTing, etc.) I fail to find any evidence that the IC-7100 can operate digital modes without (something like) a SignalLink.

Hence this N00B's plea: To operate digital and fldigi with my shiny, new IC-7100, is a SignalLink required? Or, is "...everything (I) needed..." a feature of the IC-7100 (which, if true, also means, I'm bupkis at RTM).

Your thoughts? Suggestions?

Many, many thanks in advance!

the IC 7100 has a built in sound card.

go here and look around   https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjuvPym24TUAhVHzoMKHW8XDI8QFggnMAA&url=http%3A%2F%2Fwww.w4wwj.org%2Fdigital_modes_setup_ic-7100.htm&usg=AFQjCNGggVbXGdhfjdFF-8kp2aIoeNBdkA&sig2=WE6NsHqMPysn9lmQ0vJzOg

It has a built-in sound card that works from the USB port. Check page 1-15 of your manual to see where to download the required driver and instructions from Icom. You can do Tx/Rx digital audio, rig control, and PTT all over the same USB cable between your computer and the IC-7100. No external devices needed.

It looks to be the same as my IC7300.  Just an USB  A to B cable available almost anywhere (I had several on hand) to get on all digital modes.  The audio (both ways) and the rig control signals all flow over the USB cable.  It was the easiest rig to interface to my PC for digital modes I have ever done.  Slick and easy like it should be. No stinking interfaces needed.  Smiley

I have a 7100 that uses its internal sound card for all digital modes EXCEPT packet.  I use a Signalink for that mode because I was unable to find a workable setup to key the rig during packet transmissions.  I use a software TNC.  Found one workaround on the internet that was supposed to work but didn't for me.

Interesting . . .

The IC-7100 doesn't have "digital VOX" -- that is, VOX that switches to XMIT when a signal comes in over digital audio (or the DATA port if it has one) ?

Or is the problem that packet uses quick turn-arounds from XMIT to RCV, and no VOX is able to keep up?

Thanks --

PING! 

1. I wouldn't mind seeing an answer to the open question by VA7CPC... I'm a noob too, just like the original poster

2. The w4wwj web page link above is broken as is the w4wwj.org web site.  I wrote to the guy via private message at qrzcq.com, but haven't heard back.  Anyone have an updated link for W4WWJ's IC-7100 info pages (or equivalent)?

Thank you!

The rig can be keyed by CAT command over the virtual serial port on the USB cable.  Unless his packet program would not utilize that method.   

As for the OP feeling bad about reading the "fine manual.  Don't feel that way, the manuals tell you what you need to know in a general way, but they don't give you any examples of how to utilize it in the real world, or suggestions on "how to do it".  All brands seem to be that way, just no real world explanations.  It is like they are written by software engineers that have never used the radio.  Probably because they are.

I run packet on the 7100 without a Signalink. CAT7200 (http://www.cantab.net/users/john.wiseman/Documents/CAT7200.html) providers a virtual serial port that sound modem software can use to put the radio in transmit, CAT7200 then sends the CAT command over USB to the radio. It does mean you need 3 programs running, CAT7200, the modem software (UZ7HO soundmodem or Direwolf) and then the client software, like Winlink Express. It works very nicely.

You have a very nice radio with alot of capability!

This may seem like a lot of random thoughts but here goes:

I have an Icom 7200 it also has an internal sound card. However, unlike your 7100, it does not have socket/pins for 1200 or 9600 baud packet because it is not a VHF/UHF radio. I use a different radio for high speed packet.

I did not like virtual COM ports so I added com port interface card on my computer.

I use MMTTY software for RTTY (FSK) I put the radio in RTTY mode and control the FSK keying using the FSKKey pin in the ACC port in the back of the radio, and also PTT by COM Port. My computer has rs232 COM ports on it. I made the PTT/FSK interface cable using examples I found on the internet.

I use Fldigi for other digital modes [and sometimes RTTY (AFSK)] using the regular USB digital mode on the radio, with Hamlib rig control (PTT) through the USB cable (no separate PTT cable needed).

For 300 baud HF packet on the ICOM 7200, I use UZ7HO's SoundModem with COM port PTT.  Yes there is HF packet out there!

I have a Yeasu FT-7900 VHF/UHF mobile radio in the shack that I use for 1200 bps packet data (Winlink email for example) and FM repeater voice. it has data pins similar to your IC 7100.  I run 1200 baud packet using the same SoundModem software.  I use the internal soundcard on my PC and built an interface cable to get audio to and from the radio, and also COM port PTT line, all going to/from the data port on the back of the radio.  This homebrew cable is uses the Rigblaster NOMIC device as its core component.

I don't have a 7100 but looking at the manual, I see you can do RTTY (FSK) keying using pin 10 in the ACC port If you wanted to do that. It has 1200 baud and 9600 baud data in/out pins in a separate Data2 port.  very handy!  With a couple of interface cables (home brew or pre-built), you could really give your radio a good workout on all its capabilities.

I had a lot of fun making the interface cables, If you chose to make FSK, Data and PTT cables, do so carefully.  I highly recommend getting the ACC and DATA2 connecters pre-wired pigtails (expensive but worth it).. DX Engineering probably has them.  Take care to make cables that fully isolate the radio from the PC (no common ground wires etc etc.)

But ultimately, yes your 7100 has everything it needs to be effective with Fldigi without additional cables, just the USB cable.  It has a lot of other capability that I am sure you will want to try out someday.

Good Luck and 73's

It's all gets done thru the USB.
I run an IC7410 it's easy to setup as long as you load the proper drivers into your computer B4 connecting the rig
Have fun w/the new digital modes.

hi all,

first , i know it is an older topic.

i jst connected the ic7100 to usb (first installed the driver according to instructions)  and i see it added not one but two com ports.

sorry for the probably noob question but are they both to be used by the 7100 or is only one needed?

One COM port is used for Rig control (CAT) and PTT,  and the other is used for the audio modem (audio in/out).

I know I'm contradicting the last poster, but I have an IC-7100, and the software I've used (WSJT-X and Ham Radio Deluxe) is configured to use the same virtual COM port for the audio device and CAT/PTT.    From what I've been able to infer (but not 100% confirm), the audio device is available on either virtual COM port, but CAT/PTT is only available on the USB 1 COM port.

The catch is you have to determine which virtual COM port corresponds to USB 1 on the IC-7100.  The easiest way is to simply try both until you determine which one allows your software to control the IC-7100.  Or, you can look at the properties of each port, and determine which one has a Device Instance Path that ends in "_A":

http://radioaficion.com/cms/icom-tips-for-the-usb-port-settings/

Here's a summary of how to set up the IC-7100 for fldigi.   Other software will have similar settings.

Make a note of the IC-7100 settings before you change them.  You will have to restore them before you can use the rig for SSB/FM voice.
