Please note the following:
The CTR2-Mini+ does not come with an external Radio I/O module. You can control one radio using the internal radio I/O circuit in this unit. If you want to control multiple radios using a manual RJ45 switch as shown in this post, order one Radio I/O module for each radio and remove the jumpers on the internal radio I/O circuit in the Mini+.
NOTE: If you’re interested in the PCB kit, enclosures, or an assembled original CTR2-Mini (as seen in the September 2022 issue of QST) contact me for availability and discount pricing.
