Howdy all
I finally have gotten around to setting up my TKR-850 UHF repeater.
A few questions.
I know that power is set up in software, however, I can't get but
about 27 watts max out with the software set at max even on the test
channels using LDF1 hardline, bird meter, and dummy load. Any
ideas? I know there is a power adjustment, point VR1 on the PA
board, but I can't for the life of me get it to do anything...do I
need a special tool or something? I can't get it to move. Would
this possibly be the problem or something else?
Question 2...Initially, the power out was fluctuating
wildly...jumping back and forth. I tightened up the screws on the
power transister and all the screws on the board and it seems to
have stabilized. Is there any thing else I should check to verify?
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 don't
want it to ID unless there is activity on the repeater.
Question 4...to float charge a battery, the service manual refers
to "shorting the charge land near R61". Is this the 2 little traces
on the board? Should I just solder a jumper across these 2 little
pads?
Question 5...anyone have any experience using these units in the 440
MHz range? I plan to use it in the 460 MHz range, but I was curious.
Question 6...I bought the repeater used so if I can't get the power
up to the factory specs, would I be ok to turn the power down to say
5 watts or so and run an external amp or would I be better off
putting in a 3 or 6 db pad between an external amp and the RF out
from the repeater? I really want the repeater to work up to spec.
Sorry for all the questions, but I'm new to Kenwood stuff and I'm
trying to learn.
Thank you
