Since I got the SignaLink I figured I can mess around with the Rigblaster. I wanted to adapt it to the FT-100 so If I ever go out with it and a laptop, I can do some digital work using the rigblaster as a interface.
On their website they posted a article “Connecting your FT-897 to The Rigblaster NOMIC for digital operation” (Written By Jeff, K8YSV).
I Followed the directions to the T and here it is!
Just some things I would like to point out. The FT-817, FT-857D, FT-897, FT-100D, FT-950, FT-2000 and I am sure many other makes and models use the MINI 6 PIN DIN connector which is the same as a PS2 cable that you find on a semi older keyboards and mouses (mice). I thought it would be easy and just find a old mouse or keyboard, clip the wire and use the connector. Well guess what? The PS2 Mouse and keyboard use 4 out of the 6 pins and the two that have nothing connected to them are need to wire up for the Yaesu rigs. You just might be lucky and come across a cable that works. I went through about a dozen keyboards and mouses until I gave up. Getting frustrated I went on Ebay and picked up a 6 pack of connectors for $10 w/ shipping.
If you follow the entire article on the above link you can make a cable with just basic soldering skills. I added a ferrite choke to the data and audio cables to help cut down on the noise generated from nearby objects.
After constructing the cable and testing it out, I wasn’t too impressed on it’s performance compared to hooking the NOMIC up using the Microphone jack and audio patch cables.
I notice it didn’t sound right. I don’t have the proper analyzing equipment to give a detailed reason why but if you look at the band edges on the above picture, you will notice a drop off which I never seen with the unit normally hooked up. I also notice that the audio is not as strong either. I had to max out all the settings on my soundcard and radio. Even with the levels maxed and removing the resistor on the NOMIC board, the audio still seemed low.
Overall I am not too thrilled about the outcome of the cable but it works. It makes it possible to use the microphone again and It’s going to help on a future project I have in the works.
One thought on “Homebrew Rigblaster Nomic Data Cable”
i was wondering if you have the pin out for the mic on the 857.. I have a rig blaster nomic i want to hook up to do psk31. i tried the rig blaster plug and play but can not get audio to transmit. I receive fine and the ptt works fine just not transmitting so i thought i would try the nomic setup
