Re: ribbon cable repair
I just order new cables from Icom, they were less than a ?1 each, I now have stock for the next IC7000 that comes my way KR Andrew ?Get BlueMail for Android ?

Re: ribbon cable repair
Oops, I should have written 0.05 inch pitch. Well, my attempt to repair that cable only made it worse.? I glued the strips down, scraped off the extra glue, reassembled, and the radio wouldn't even

Re: ribbon cable repair
Hi switch on select VHF and measure the voltsge on the gate, if the bias is set low there should be low volts on the gate. Check the spec of the transistor, and check where it is, most RF Fet's turn

Re: ribbon cable repair
I ordered some from ICOM for a friend less than a year ago. As you can see, you need a spare. Bob W4JFA [email protected]> wrote:

When I was reinstalling the MAIN board, I noticed that some of the conductors had lifted from the ribbon cables.? I squeezed them down, flattened them out and got them into the sockets anyway.? The

Re: Interpreting transmitter adjustment instructions
Hi you have a ribbon cable fault which is putting DC on the gate of the VHF transistor, this needs to be fixed first. KR Andrew ?Get BlueMail for Android ?

Re: Interpreting transmitter adjustment instructions
Thanks for the confirmation, Andrew. In the first setting, "TX Driver Idle", the radio drew 1.57A at setting 00, which gradually increased with higher settings until it went from 1.80 A to 2.67A

Re: Interpreting transmitter adjustment instructions
Hi the way to look at this is this: 1. Connect an 1-5 amp meter (DVM) in series with the rig, or use a power supply that shows current digitally. 2. Set all the bias controls to zero 3. Switch on

Re: IC-7000 different Power at different band
Hi Dave, Thanks for reply. Dummy load is ok (I use the same one for my SSPA testing, and also 7300 shows ok). I have done some more measurements, specifically on J101, Driver IN and Driver OUT

Re: IC-7000 different Power at different band
Silly but have you tested the dummy load is it still 50ohm on all bands being used on, Dave 2E0DMB [email protected]> wrote:

IC-7000 different Power at different band
Hello all, Greetings. This is my first post in this group. Last time when I fixed my IC-7000 I took help from the IC-7000 Yahoo group ;) back in 2009. After almost 12 years I brought this radio out of

Re: Service Menu IC-7000 Tune Power for a Screwdriver/controller
The rocker switches are what I started with. To change bands one needs to stop the vehicle or risk a violent/fiery death. The thing is, it works MOST of the time, until it doesn't, usually on 80/40.
Re: Service Menu IC-7000 Tune Power for a Screwdriver/controller
I was never happy with any auto-tuners I has thrown money at. I found them to be sensitive to RF no matter what I did. The fact that they told you to lower tuning power is a proof yo what I
