It’s just volume. Whistle, say a long ‘fiiiiiive’, white noise; all good. Just drive it as hard as you can. You don’t need an RF meter of any sort to set idle current. Thank You Paul

Thanks for the feedback Paul. Very good. For the idle current adjustment all I need is an rf meter and an ammeter. That’s ok. For the power adjustments, when you say “saturate the mic with

You can probably skip the drive adjustments and maybe the power output adjustments but you absolutely need to do the idle adjustment. You do need a special set up for the drive (not driver)

Hello All, I have a couple of 7ks. ?A newer one works perfectly, as far as I can tell. ?An older one has low output and the driver board is suspect. ?I intend to replace the driver board - new

It's an old topic, but just to affirm that replacing C501 & C502 for new ones solved my problem.

Hi, All, I'm still seriously searching for an MFJ-7000, or an MFJ-706, for an emcomms project. Bob, G8IYK

Hi If the defect appeared after the driver was repaired, I will change 2 ribbon cable between PA unit and MAIN unit. 73s Pasquale IW0HEX

G'day.... I have an IC7000 on the bench that has me stumped for an answer for a few months now, it came to me from a friend and the driver had burnt up with the owner noting that it had odd audio and

Pasquale, Paul, Thank you. I see Mouser has them in stock, $21. I may attempt to fix that burned board. Good project for a rainy day. Shipping to you may be quite expensive but it's only 900 miles

Thanks Bob I fixed 2 ICOM 7000 with PD50015 burnt ; compliments for your job and thanks for your feedback Best 73 de IW0HEX Pasquale (Rome, ITALY)

Hi all, I've attached a picture of the burned and new driver boards. There is a 1 ohm resistor on both. I hope the picture isn't too large for groupsIO. Bob W4JFA [email protected]> wrote:

Congratulations on successfully replacing the driver board in your IC-7000. Replacing those flex cables from the PA to the MAIN is a real challenge. Now for the reason I’m jumping in on this.

That sounds like a good idea. My 746 has a fan on it 100% of the time. Bob W4JFA [email protected]> wrote:

Got it done. Full power out on all bands. Old board burned. There was no heat sink grease on it. It looks like the heat sink design is good but why would they apply grease on everything else but not

Richard, That sounds great. I'm an electronics cooling nut. I have extra fans, or stronger fans on just about everything. I have an Icom 746 with a fan that blows air into the vent on the top 100% of
