SS 3900 TX/RX problem i think

N

Hi all as you know by now i have a SS 3900 That i sent to truck king just befor christmas for a full service and a peek and tune and also to have the bands put back in the correct places.

So that aside i have some problems i think might be somthing to do with the vco being out possibly.

Here is the problems.



(1) People on the uk FM keep telling me that i sound off frequency that my voice and modulation sound slightly off but my beep sounds like its at least 2KC out.



(2) Today i was listening to USB/LSB and had my rig turned up about quarter volume i noted that the volume wil all of a suden go quieter and the meter will drop about 2-3 LB and stay like it until i crank the mike, as soon as i key the mike and let go it goes back to proper volume and meter reading. This problem seems to ocure on all bands not just USB/LSB i just used USB/LSB because thats when i noted the problem.



Here is what i have done to try and resolve this isues.



(1) for the problems with transmit i use my corse clarifier turned right to the left for the uk fm band. I am told this should be positioned at 9 Oclock although when i reposition it from far left to 9 Oclock this makes the people i am reciving seem off frequancy to me and very hard to understand what is being said. If right to the left like i have it people ar very clear and loud.



(2) for both problems i have moved my antenna onto a higher pole and moved its location i have also ran a brand new length of coax to it and even bought some new PL239's.



Does anyone out ther have any idea what could be the problem. VCO maybe ?????? The rig never had this problem befor it went into the shop.

I would realy apreciate some help on this PLEASE i just want to get my rig working properly againe.



Final point to be made is i have also opened my clarifier could this be the problem with the tx being off if so i will reverse the mod if i can find out the resistance of the resistor i removed and what diode i removed.



THANKS in advance
