Mike, Mobiles by their nature don't make good Repeaters, They are usually low duty cycle, so need to be set for lower power or force cooled. Something like the T555 is 25Watts but at 33% duty cycle, that is 1 minute TX and 2 minutes RX. The hole in the back suggest sonething connected, but could have been for telemetry, data etc.
The T555 can be trunking T555-81 or 91 others are conventional. For frequency if the diode link is open add frequencies as below. Diode coding is: Diode MHz N9 409.6 N8 204.8 N7 102.4 N6 51.2 N5 25.6 N4 12.8 N3 6.4 N2 3.2 N1 1.6 N0 0.800 A5 0.400 A4 0.200 A3 0.100 A2 0.050 A1 0.025 A0 0.0125 niteviser --- In [email protected], "Floydiboy007" <floydi...@...> wrote: > > Hi all. > This is my first on this group.Better late than never.
