Re: LO off QRG
Steve, when you change the tuning voltage wired to the VCTCXO the TX frequency (measured with a counter at the dummy load) has to change too, imho. The 7000's firmware or hardware has not got any

Re: LO off QRG
Igor,
There is much that goes on in the firmware that makes it hard to predict how the hardware will work. But the behavior you see is normal. Setting the REF frequency accurately will either solve

Re: LO off QRG
I've asked Icom Europe on this (a week back), none answer yet.
My gut feeling tells me the change of the maintenance mode REF setting from 0-FF must change the TX frequency in AM CW RTTY modes,

Re: LO off QRG
I once had a 700 with exactly this problem.
Cannot calibrate down, reaches 100 % in menu 51.
What I found is the analog control voltage to the oscillator chip VFO
was off and not in spec. Voltage

Re: IC7000 with ACLog
Please re-read the question. Slightly different application, where two data ports may be involved.

IC7000 with ACLog
Using the 7000 with ACLog. Connected data port on rig to laptop with RigRunner. Works great to capture the frequency. How do I connect the rig to the laptop for ACLog to transmit CW please? Thanks!

Re: IC7000 No power on, no relay click
Good job! It is important when handling all of the circuit boards to use proper ESD protection. I notice one picture of the LOGIC board laying on what appears to be a synthetic cloth surface.

Re: IC7000 No power on, no relay click
Good job Steve,
Now i can starting to control those things on my propre 7000 with the same problem...
question...is there a posibility to test the rig without the pa board...to exclude problems in

Re: IC7000 No power on, no relay click
Hi Jeff:
Excellent write-up. Very nice deep dive!
I have a DeWalt radio with a mechanical-digital encoder that failed. Found a replacement encoder at Mouser.com. I ordered a tray of 12 of them and it

Don't know if it's the same, but just found this if your repair doesn't work out. It looks very similar.

That is very good detective work. Glad to see troubleshooting on that level. Not sure if anyone else has ever had the issue of the memory bank switch on the IC7000 not working correctly but I'll add
