N3KL 23cm repeater

N3KL 23cm repeater project

23cm repeater antenna
Repeater antenna is on top.

The repeater went on the air 12/15/2001
Output: 1286.1 MHz
Input: 1274.1 MHz (-12)

Current Status Operating with reduced output power (~12w to antenna) due to PA failure.

Purpose to provide an opportunity for local area hams to use the 23cm band more frequently, and to challenge them to improve their skill and equipment by working this difficult band.
Coordination Full Coordination was issued by T-MARC on Feb. 16, 2002.
Exciter TM-541 modified for modulator input.
Power Amp Currently shopping around
Receiver TM-541 modified for discriminator output
Duplexer TxRx Systems 4 cavity bp/br 23cm Duplexer
Antennas/Feedline Diamond U200A fed with Andrew LDF4-50 7/8" hardline.
Controller Cat 200B in minimalist mode
Other Behringer PEQ-2200 Parametric EQ (for pre-emphasis)
Behringer 8024 DSP (for delay and de-emphasis)
