RF Switch Boards for KSDR

Post by ckoval7 » Mon Feb 01, 2021 12:33 am

A little over a year ago I built some RF switch board to avoid having to disconnect the antennas every time I changed frequencies. There's been some interest from other users and I finally got around to making a large number of them to sell on Tindie.
If you're interested you can buy them here:https://www.tindie.com/products/lakesho ... -ohm-load/

Some basic instructions can be found here: https://github.com/ckoval7/kerberossdr/ ... f_switches

I've had good results with the switches and they've allowed me to mount my KSDRs in remote locations. They have an internal 50 ohm load, so both antenna ports 1 and 2 can be used for different sized arrays.

These look great.
Hopefully there are still some available when our project moves forward mid-year.

Very nice, i'm going to sticky this.

May get in contact with you again soon to promote these to V1 customers as we begin to eventually roll out V2 later this year which will have switches built in.

Any idea yet when the v2 hardware will ship? I am going to do an antenna upgrade in the next few months and was hoping to mount one at the same time.

It will still be a few months out unfortunately. Crowd supply page here: https://www.crowdsupply.com/krakenrf/krakensdr
