Just a hint, the board and surrounding components are the primary concern when servicing.? There is no need to be "pretty" about removing a suspect part.? My first pass at this would be a wide, flat

Thank you Geoff, and Neil ZL3ADC I've now ordered some 1.5 mm Gootwick also!? ?I think that I'll do some practice with the braid on a scrap board before tackling the IC-7000.? I have found a

Hi Steve Saw the picture of the heatsink, you could probably do better with some copper plate. File it so it mounts the same but indented to touch the two devices case, add a bit of heatsink compound

Steve, spring load solder suckers on smd's can be disastrous. 2.5 mm braid will take too much heat which could lift tracks and otherwise do damage. 1.5mm is much better for smd

Thank you, Neil I'll be sure to check the PTH, and surrounding area.? When the fault is 'off', the FET (Q102) really does get very hot indeed during normal use.? I suspect this really stresses the

Hi Steve From the pictures, great job by the way. Under magnification looking at the plated through hole by the 560 ohm resistor and device it looks like there is a crack in the green coating, whether

The fault on/off conditions are most sensitive to pressure applied to: the case of the FET (white arrow); the drain terminal; the gate terminal; and an area of the board near to L103 (white arrow).

Hi Neil The soldering on the FET doesn't look as nice with my extra solder blobs, but I do feel that replacement of the suspect FET is now the next step.? This will be an IC-7000 strip-down task,

Hi Steve It is not conclusive that they are connected from that data sheet. It may be that the tag is for heat transfer only and in this case is soldered to ground merely for that reason. If you could

Hi Neil Thank you, again. The DC conditions on the gate and drain are consistently OK - regardless of whether the fault is present. With the FET still on the board, both the source and the tab are

Hi Steve I have had a look in the manual at the board, there are resistors on underside and mostly RF path on topside from what I can see. Can you indicate where you are putting pressure on the board,

Hi Steve There are 2 voltages 2.81V and 8V mentioned on circuit diagram. The 2.81V appears as a voltage divider and feeds gate through a resistor and the 8V appears at drain through a couple of

Neil ZL3ADC: Thank you. I'll do the fan modification once the rig is working again. To All: Regarding the pre-driver device *Q102* , RD01MUS1.? ?This device seems to be most sensitive to tweaks of

Hi Steve Yes plated through holes could also be an issue, I have seen where a track has cracked very close to donut on one side of plated through hole, very hard to see. I have also seen plated

Hi Steve There are two fan mods.this is the one I did. Contact author: M3SVO !! IF YOU ARE UNSURE ABOUT PERFORMING THIS MOD DON’T!! !!IF YOU DAMAGE YOUR RADIO YOU ONLY HAVE YOURSELF TO BLAME!! I

Hi Neal I'm very grateful to you for your thoughts.? ?I have never used freeze spray, but I have heard good things about it when used for investigating intermittent faults.? I have now ordered a

Hi Steve I have not seen this fault personally. I am an ex radio technician of many years. And I own a IC7000 myself. From what you have described, I suggest the fault is more likely physical than

*IC-7000: Intermittent Loss of Pre-Driver signal* I've owned my IC-7000 for about three weeks, and it's now got an intermittent transmit fault affecting all bands. The fault can be made to come and

My IC-7000 is for sale. Includes new separation kit. Please email kc9c at yahoo for more information. Mark KC9C

Interesting question, could anyone find information about the values ??of the IC-7000 Main Board L701 Transformer, the coil itself can't be found anywhere, so you have to do it if you don't happen
