XenceLabs Quick Keys For SDR & Other: This is an as new Quick Keys that I bought for a RasPi SDR project, tested and didn’t use. It is complete in the original packaging, latest firmware. You can connect using a cable or use it wirelessly with the dongle. You can go to the manufacturer’s website for all the details but in a nutshell it allows you to program keys with graphics and rotary encoder in place of using a keyboard & mouse. A number of the integrated HL2 builds use it. Smoke free home. $65 shipped, payment method your choice.; Listing #1766107 - Submitted on 04/25/26 by Callsign KK4HP - IP: customer.mmmiflx1.isp.starlink.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
