Quick Guide to WSJT-X on the Icom IC-7100

We had a great presentation today by Wendell, N4VLK,  on the digital mode FT-8 today at the CARS club meeting. I was asked if I have run FT-8 / WSJT-X on my IC-7100. Yep, I have, and it works quite well too. I know where are a number of guys in the club that have the IC-7100 so I thought I would share my setup information.  Here is a very quick guide on setting up WSJT-X on the Icom IC-7100.  I am assuming that you have already installed the Icom supplied USB CAT and USB Audio drivers.  If not, do install them before continuing with the WSJT-X installation.

First, download and install Dimension 4, an app to keep your clock synced to the NBS time source. This is very important to make sure your receive and transmit timing is correct, otherwise WSJT-X will not decode signals and other stations will not be able to decode your signal.  (you can click on the images below to see a larger view)

Website for Dimention 4

Installation is pretty straight forward, select a sever to sync with and click the Sync “Now button.”

Dim 4 Install screen

Once you have Dimension 4 installed, go to the website for WSJT-X and install the Windows version.

You can use the defaults for the install.

Run the WSJT-X program and you should see two windows, the waterfall display window and the main window.  In the main window click “File” on the top menu and select Settings from the pull down.

On the General Settings tab, enter your Call and your Grid Square information

Then on the Radio tab enter the info for you CAT port for the IC-7100.  Select the radio type, then the serial port, in my case it is Com 6, and select CAT for the PTT. Once these settings are complete you can click on the “Test CAT” button at the bottom right of the window.  If button turns Green your CAT is setup correctly.   You can also test the PTT function with the “Test PPT” button.

Then go to the Audio Tab and select the USB Microphone and Speakers for the audio interface.

A couple more settings and we are done!  Now go to the Reporting Tab and set the program to send data to PSKReporter website.

Close the Setup window and one final setting is to the “Mode” on the main menu bar of the WSJT-X main screen and set the mode to FT-8.  Can also run other modes with this program if you desire.

Ok, you should be ready to operate at this point!  I suggest watching for a while to get a feel for what is going on with the program.  Also, reading the user guide will be a great help.

Have fun on FT-8!  If you have any questions that I can help you with email me at bob@n4rfc.com.

This makes me laugh

This is something that you won’t see on the NBC Nightly News. A investigation by the GAO tried to buy illegal guns on the internet. Their results, other than some obviously illegal gun dealers on the Dark Web where no guns would be sold by dealers on the web when they knew the buyers were not allowed to purchase firearms.

Like I said, you won’t see this on the Nightly News!  Or on CNN.

Interface cable for Icom IC-7100 to a PK-232 Packet TNC

I was trying to interface the Icom IC-7100 to a PK-232 MBX Terminal Node Controller (TNC).  On my Yaesu radios it is a pretty simple matter to put a 6 pin mini DIN connector on the end of the PK-232 cable and have everything working in a very short time.  However, it wasn’t that easy on the IC-7100.  The IC-7100 is a great little radio, covers just about DC to daylight in a very compact package.  But I wanted to have the ability to use it on VHF packet radio, so interfacing the PK-232 was a requirement.

After trying the data port and the accessory port I realized what the problem was. There was no squelch on the audio from these two outputs. I found that information on using this new radio with a vintage TNC was very hard to find. Reading the manuals supplied with the transceiver didn’t help much.  After some additional investigation I saw that audio output from the receiver was available at the mic jack I then knew how to make the cable.  Since that was from the speaker it would be squelched.

Here is the connections to operate the PK-232 Terminal Node Controller with a Icom 7100 all mode all band radio.  Below is the cable details for creating your own interface cable.   On the left is the rear view of the RJ45 microphone connector on the IC-7100 matched up to the wire colors of a “standard” PK-232 radio cable as supplied by Timewave.  If you are using a Kantronics TNC look up the pin outs for it’s connector in the manual or on the web.  It should work just as well, although I don’t have a Kantronics TNC to test here.  If anyone out there tries the Kantronics drop me a note and let me know how it worked.

To enable the audio output to the microphone jack, you need to turn on “Speaker Out” in the function menu.   Press <SET> then select <Function> on the main menu, then scroll down to <Speaker Out> and set that on “ON.”

The law what allows the President to ban immigration

I went to look for myself that the law says about the President being allowed to ban certain people from immigrating to the US.  The clause is in U.S. Code  Title 8, Chapter 12, Subchapter II, Part II, § 1182. Here is a link to where I found this statute:

https://www.law.cornell.edu/uscode/text/8/1182

Scrolling down, very far down in this text you will see this clause:

(f) Suspension of entry or imposition of restrictions by President

Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate. Whenever the Attorney General finds that a commercial airline has failed to comply with regulations of the Attorney General relating to requirements of airlines for the detection of fraudulent documents used by passengers traveling to the United States (including the training of personnel in such detection), the Attorney General may suspend the entry of some or all aliens transported to the United States by such airline.

That’s it folks. Says the President can do what Trump has done for as long as he wants to. Jimmy Carter did it, Bill Clinton did it, and the darling of the left, Barack Obama did it. But for some reason the Left has decided that President Trump can’t do it.

Really?

Noise Burst?

I see these bursts of noise from time to time on 40 meters. I have expanded the spectrum display and it is fairly broad band but it varies in amplitude across the spectrum. It doesn’t look like typical noise and sometimes I wonder if it is a sampling Phenomenon in the SDR as a reaction to a noise input. Has anyone else seen this. Today when I saw it I logged into my buddies system, a Flex 6700 in North Carolina to see if it was wide spread. Didn’t see it at all on his Flex. I have uploaded a short video from my phone camera.

Does anyone have an idea what this might be?
