Setup and Configuration

Changing Frequency

The pager's frequency is set by a crystal. You will need to get a custom crystal cut for your frequency.


The UHF Advisor pager was configured to work on the DAPNET( frequency of 439.9875 MHz.

The custom crystal used was sourced from KRYSTALY, Hradec Králové, a.s. ( To achive the frequency of 439.9875 MHz, a crystal of 49.37634375 MHz was used. This is a 3rd overtone series resonant crystal. The holder is UM-1.

Programming Software

Programming software is required to set things that impact the pager operation, including setting the CAP code. I was able to find the software archived here:

Serial Communication

The pager uses 3.3V TTL 9600 baud 8N1 serial to communicate with the programming software.
