I aquired a Radioshack PRO 92 "B" but it doesnt seem to want to trunk.
The system is San Diego and is a 3600 baud analog system. All the
frequencies were entered, including data channels. All "D" was
removed and MO entered manually on all frequencies as they were
entered. Is their a trick to get it to trunk when you turn it on? By
the way it is a 3.28 firmware version.
