DIY Automatic Remote Multi Transveter Interface for Single XVTR Port

Hello,

I thought I would share a project that I am working on to provide switching of multiple transverters from the single XVRT port on the 6400. I am sure there are simpler ways to do this such as using DPST relays for the RF switch. However, this seemed to be something I was more comfortable with and I already had the SaniSwitch relay. I found the Chinese DIY remote antenna switch kit on ebay and felt this would make a sensible combination and provide isolation for the rf inputs to the transverters. I will post the USB Cable settings from SmartSDR once I complete the project and fully test for proper operation. I will be using the inexpensive Transverter Store devices for this project.

Any comments or suggestions would be welcomed.

Don

    Very cool Idea and it interest me quite a bit but your Pictures are pretty low res and blurry, can you send the pictures on google share or something maybe to [email protected] that has better resolution. 

    Thanks so much and great Idea

    This might be of interest to you:

    This unit does all of the above and automatically selects the transverter and no actual mechanical relays. I have already ordered the board (months ago but no time to finish it) and am finally putting the box together. Mine will be rack mounted. Maybe I will post pictures once done. 

    It can also be stacked, as in 2 sets which I am considering as I may pickup a 902 (33cm) transverter at some point as well as a 23cm one. 

    I use IF A for 630m experimenting, IF B for VHF transverters and Receive A for my AOR loop so pretty filled up! If you are active on VHF/UHF and like to have the waterfall on them, a switch is a must. Let us know how it goes.

    This project is complete and works as expected. If you have any interest you can see the final product and cable settings on my QRZ page.
