Hey guys, im setting up a repeater here on a 40' tower we have. Frequency coordination is done and just waiting on FCC status to get out of pending. Picked up a tkr-750 v2 for $400 locally. Going to use a duplexer from china that has a good track record with others ive read about (same one that the msr2000 uses from what i understand). Running 75' of LMR-400 up the tower to a mast on the top section with a TRAM 1491 antenna on top of it.
Questions,
The TKR-750 can put out 50 watts at 50% duty cycle....a little confused by this. What time periods are we talking here? I can picture in a 12 hour period to have way less than 50% use, but during a event we may be using the repeater on a conversation for 30 minutes or so back and forth between mobile users hitting into it. Will the tkr-750 handle this safely? What happens if you exceed the "limit"?
If I want to run a amp to up the unit to 100 watts (and keep the tkr in the low 25-watt mode for a 100% duty cycle), where does that amp go...in line on the antenna feed or between the tkr transmit bnc and the duplexer? I would assume the later, but never ran a amp before so new to that!
Coming from the ham world so a little new to this, never setup a repeater before...
