The exciter board makes about 500 mw, the tripler makes anywhere from 1.4 to 2.2watts, frequency dependant. ----- Original Message ----- From: John Everson To: [email protected] Sent: Sunday, April 08, 2007 10:42 PM Subject: [Repeater-Builder] UHF Micor Exciter Output Level??
Hi Guys. What is the power output of the UHF Micor (VHF really) exciter BEFORE the 1st bandpass filter? What about AFTER the 1st bandpass filter? I have the manuals, and I know what they say, but I am looking for some real world data. I have got to be doing something wrong or all of my spare parts have gone south on the shelf. I am not at my wits end but I can see that it isn't too far away. Here is our story. We had this 75 watt UHF Micor repeater donated to us. The PA was bad. The fellow said "that's it, I ain't fixing this thing again".We thought we would fix it, tune it on a new channel, and donate it to a fellow that is in need of new hardware. The PA was bad, I discovered that all of my spares were junk, or near junk. Then, the tripler takes a dump, replaced that... 1.7 watts out of the tripler, now we are getting somewhere. I go and hookup the controller, intermittent COS... cracked backplane solder joint, fixed that. A day has passed, and now I have no output, again. I backtrack and find only 10-15 milliwatts out of the exciter direct, less out of the 1st filter. I have tried two other exciters, on the original channel elements, one is dead, and the other has only 10 milliwatts out. How did Charlie Brown put it??? ARRRRGGGH Am I missing something. Perhaps I have been messing with the GE stuff too long. Thanks in advance. John
