The new version B26-PA RF2K-S 


The RF-Kit B26-PA RF2K-S comes at first as a kit. In this case Kit does not mean that you get 100 plastic bags with individual parts, you need to assemble and solder boards, drill housing parts or connect the PA.

The PA kit is always delivered as an almost finished device. To make the kit an operational device, it is necessary to obtain a Raspberry® Pi 4 - 2GB and a power cord. All other necessary parts such as 1 x coaxial cable, power plug, USB cable, HDMI cable and micro SD card are included in the scope of delivery.

To finish the kit the Raspberry has to be installed (spacers are already mounted for this purpose and also the necessary fixing screws are included). Connect the supplied USB and HDMI cables, solder in the coaxial cable. Thereafter, commissioning takes place with the necessary calibration / setting.

No special tools are necessary for all this work. Screwdrivers, soldering iron, DVM, Ampere meter / current clamp and RF power meter are everything.

If you have any questions, please contact RF-Kit and a very large community at Groups.io with more than 1,300 members. A current version of the operating instructions is also available there at any time.

A micro SD card is included. Since the PA has a LAN port for possible "remote operation", the operating software can be downloaded from the Internet, and always updated with the availability of a new version.
