Re: IC7000 no HF power out but VHF/UHF ok
Hi Tommy
not easy to find these type of issues, check dc voltages around the final circuit, coupling capacitors and switching devices.
Good luck

Re: shut down / restart on keying, now no power
Make sure that all of the power connections are clean and tight. If the fuse holders are still in your power cable especially make sure that they are clean, bright and tight.

Re: IC7000 no HF power out but VHF/UHF ok
James,
All functions work on all bands for receive. Because of that I believe the
filters and switches are functioning properly.
There is no SWR, power meter or ALC meter for HF transmit at any

is the power being throttled ? Any heat being dissipated due to current draw? look for hot spots

Re: IC-7000 no rx and no sound out from speaker
Hi Geoff
nothing on the S-meter, but occasionally the unit starts to splatter high levels of audio when warmed up - nothing recognizable just splatter.

Re: IC-7000 no rx and no sound out from speaker
Good work James. Did you see anything on the display like a reaction on the
S meter. Won't be surprised if not as some of the clocking inputs to the
codec chip come from the clocking I/O pins of the

Just out of interest i would like to compare settings just in case mine are too far out. If anyone can compare with their settings that would be much appreciated

Re: IC-7000 no rx and no sound out from speaker
Hi All
Confirmed the audio circuit from IC551 to speaker is ok by injecting 1khz tone at various points after IC551.
Now waiting for the replacement ic551 to arrive.
will keep you updated

Re: [IC-7000] Re: Front panel troubleshooting
James can you capacitively feed an audio signal, no greater than say 3Vpp,
onto the pins 25/26 and see if you can hear/see any reaction. Monitor the
signal at these pins with a CRO to see if its
