SOURCE: refurbished dx 959 from galaxy no modulation? no transmitt?
If there is no transmit at all, it sounds like it wasn't fully refurbished. If it is just low modulation then just turn VR16 and VR14 all the way to the left.
If its not working at all, send it back. It hasn't been refurbished.
SOURCE: how to fine tune channel settings on dx 55v galaxy
Take it to a reputable Service shop. They will likely do it for little of nothing. A full tune up could be needed ask them.
SOURCE: i just want to know the procedure for tuning or
this is for any radio.
follow the audio wire. to the variable resistor on that line. for your
modulation. for TX go backwards from the rf transistors to see if there
is one for rf power actually would be a voltage increase/decrease to
the bias. and collectors. thats how to trace any radio for the tune up
adjustments. the others would be for ssb or rx tx meter and squelch
etc... just follow them thru the circuit ... all this can be done by a
radio shop for less than $10 remember not to let or yourself cut out any
of the circuit that will cause overmodulation. and its just wasted.
looks good on a wattmeter but not on a oscilloscope .. and other on
adjacent channels.. lol..
