Hello Guys
I am attempting to restore a Harris SX-1 transmitter from the dead.
I have it to the point where it turns on, but no RF output. No current indicated.
I have checked every fuse in the box all test OK.. Checked all Mosfets. all tested OK
Upon hitting the power switch..
at #00 I get no alarms indicated
#01 I get 240VDC
on the meter I can get up to the 99 Volts
No output.
all the fuses pass at 119
all the temps are around 25-32 OK
However I thought I should get
at #10 an indication of 100( IPA) I get 14
THe IPA board tests OK.
PDM issue?
when I first got the unit
It was 100% dead would not even energize.
I had an osc board issue(alarm code 4)
Fixed that.
and a #2 alarm over current ( resolved that also.)
all the voltages are there..
240Vdc
99Vdc
+5V
+15V
+10V
But still no RF Out... what am I missing??????
any help would be great..
