Re: shut down / restart on keying, now no power
I had that problem some years ago. I was using a Samlex PS with fused wires and molex connectors. Very frustrating. I shotgunned it this way: use Anderson connectors, no inline fuses and sold the Samlex and use the little West Mountain Radio PS. I did not change the factory molex on the back of the radio. I just bought some connectors and made a little pigtail with the factory molex-type at one end and an Anderson connector on the other.?
Also, I want to add this was quite a few years ago and I got help on this group to solve the problem.?

I have been trying to install version 2.6.1 and I get ?a failure message - can't find ".hamlib_settings". ?Should come with the WSJT program or do I need to find it somewhere? ?I'm using a Linovo Yoga cpu and a IC7000 with a Signalink.

Re: shut down / restart on keying, now no power
I've had this happen to me in the past. Fuse holder connections, power connections, even one time a defective fuse. The fuse read continuity with a meter on ohms but would not pass any current. I asked a professional radio tech if he had ever seen that B4. He replied, "yes, rare but I've seen it before" Bob W4JFA
Hi Colin, These things are ALWAYS caused by power input failure, which only shows itself when you transmit. There is a poor or corroded connection in your power supply leads. As the other posts have said, clean?every contact you can find, De-oxit?everything, and for final confirmation, attach your voltmeter to the power outputs of the 4 pin Molex ATU socket at the back, and watch the voltage?when you push the PTT. You'll find the pin-outs for that socket in the !C-7000's manual.
Good luck! 73 Dave? Reece????

Re: IC7000 no HF power out but VHF/UHF ok
Signal level tracing with a 'scope is the way to go, looking at the levels in and out of the driver and to the finals.?
It is always possible that there is a problem past the finals as well.?
Sometimes you just have to drag out the test gear and take a look.

Re: shut down / restart on keying, now no power
Hi Colin,
?
Check the fuse holder! open it, remove both fuses and clean each end, and also clean the contacts inside the holder.
?
That should solve your problem....

Hello all,?
?
I have a problem I'm hoping for help with. Three different times last week, my IC-7K shut off when I keyed and then immediately restarted. I've never previously experienced this in the two years I've had the IC-7K, with daily use (99% CW). The third time it shut down/restarted I was in the middle of a traffic net, which I finished after the rig restarted, no problems, and I turned off the rig as always. And then it wouldn't turn back on.
?
I know very little about electronics, and I'd very much appreciate any thoughts.

Many thanks,
73,

Re: No TX audio on JS8CALL
I'm bringing this thread back to life because I'm having a similar problem with my IC-7000 using the 9600 baud rate. I have a DigiRig Mobile and the idgiRig 6 pin DIN cable, fo rCAT control I am using a USB cable separate from the Digi. The software is VARA FM. The radio is set for 9600 baud per the manual on page 116. I do have audio at the digirig but at the radio when it is in xmit mode the audio input is very low. I have all levels on my laptop at 100% and I have tried different levels thinking I might be overdriving the radio. Just for grins I thought I would also try it on my Yaesu FT-7900R since it has the same 6 pin connection and I still have low output. I don't own a scope so I can't measure the output, the Icom likes to see about 0.4 Vp-p or 0.2 Vrms. Of course, the radio works fine on the SignaLink using the 13 pin cable on HF, but FM comms at 9600 baud is my main goal here. I hope somebody has this figured out. Laptop is running Win11.

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.
Also if you have a dummy load see if with a short cable to it the radio still cuts out. (after cleaning the connections.)

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 power setting.? Only a very slight deflection at the external power meter (less than 0.25W).? The deflection increases slightly for 10 meters and 6 meters but all well below 1W. It is just not amplifying significantly beyond the driver. I am puzzled Thanks Tommy KF4RWG

Hi Tommy
check the components within the boxed lines in the below picture .
make sure the correct LPF is active for the selected band in use.

IC7000 no HF power out but VHF/UHF ok
I purchased the radio with this symptom. ?Everything seems to work for VHF/UHF. ?This means the driver is functioning. ?When I trace the HF signal with a scope past the driver I do see a signal that varies with the power adjustment. ?This indicates to me that the ALC is functioning. ?The finals were removed and checked good with a transistor checker. ?The HF signal through the driver output seems to lose amplitude down the path through the finals and is negligable at the antenna connector. ?All this through a power meter and a dummy load. I would appreciate any suggestions or help to diagnose the problem.

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.
The 8v regulator underneath the main board gets pretty hot - from what i have read this may be normal.
Just waiting for the replacement Ic551 now

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 ADSP chip along with the chip select for the codec IC551.
Well you've proven the audio path from AOUT +/-, now to get a digital codec signal out of SDTO and back into SDTI.

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
