A CT-16 communicates with the radios at 1200 Baud only. It works fine, if you want one radio track the other as you change the frequency on one radio. For using a satellite tracking program to control your radios, you still need a signal converter such as the CT-17, but such a thing can be homebrewed easily. If you use a Kansas City Tracker / Tuner for antenna and radio control, it will do the signal conversion for you but needs an ISA slot in a computer. But, if you want to take advantage of tracking provided by a satellite tracking program such as SatPC32, you may run into timing problems unless you let that program communicate with your radios at 9600 Baud. You also have to disconnect the CT-16 every time you use computer control. I have done that for quite a few years, but used relay type switching circuits to easily change from CT-16 to computer control.
The purpose of the CT-17 is to change the signal level of a computer's serial port, e.g. com1, to the signal level needed by the IC-706. The CT-17 works great for that. I have used a CT-16 in the past, but don't use it any more. I use a CT-17 now, through which you can control four radios. I use my CT-17 to let the computer control the frequency settings and Doppler shift corrections on my vintage ICOM radios. At the moment, I am using an IC-275 and an IC-706 for my satellite station, connected to my computer via an IC-17 and a USB serial converter.
I hope that helps. If you need more information, feel free to contact me.

I am considering using a Icom CT-16 Sat Interface with two IC-706MKIIG radios. I do not have a CT-16 and want to know if this is the best route or are there other after market interfaces or software that can be used or plans for a homebrew interface. Hard to find a used CT-16 so far on the internet. I assume that I will also need a Icom CT-17 Level Converter or one of the equivalent models out there made by other hams. Appreciate any advice. 73, Robert W6RQR _______________________________________________ Sent via [email protected] Opinions expressed are those of the author. Not an AMSAT-NA member?
