Hello Again, By the way, any TKR-850 repeater that you have that has the old style PA deck is destined to burn up apparently since Kenwood will replace any old deck you have for a penny. You have to go through a Kenwood dealer, matter of fact Kenwood will pay the dealer $82.00 in repair labor. Mine were out of warranty by two years and the still replaced them, charged me 5 cents.

These are normaly 3 point adjustments so you will have low med and hi freq adjustment plus a test tab. I would not turn the repeater down to 5 watts there were problems with the x50 repeaters with the PA's and running low power it was burning up the transistor and the PCB around them (look back in the archives of this group I thank you will find what I'm talking about). As far as rated power goes they are a 40 watt 50% duty repeater or a 25 watt 100% repeater this is Kenwood spec. If you are not getting 40 watts something is wrong. Don't listen to people when they tell you that it's only a 25 watt repeater that is WRONG. Good luck BTW they do work very well in the Ham band.

TKR-850's should make at least 40 watts when programmed for high power. >> Question 3...The CW ID turns itself on every "X" minutes regardless >> of how I set it in the software...am I missing something?

I really want the repeater to work up to spec. <--I think you should look into why it won't make 40 watts when programmed for high power (assuming the usual suspects, such as SWR and a 'non-flakey' cable/connector/power meter isn't the culprit).
