AT-180 ATU is not intended for IC-7300. Icom IC-7300 have a built-in tuner already. maybe you can use a special cable or interface to use the AT-180 on IC-7300.

Look at pages 16 to 20 in the user manual. This may give you some insight as to haw this may occur. Also, A google search for this radio brings up a lot of useful info. This is a complicated radio as is indicated by the 80 page user manual. It's not one that you can pick up and use right out of the box!

The link below should help you. Lots of info in the service manual. It's intended to let someone rebuild the radio from the ground up.

Try using an external speaker and see if you have the correct volume level. Radio speakers fail often, especially when used at high volume. The simple fix is to replace the speaker. It is seldom for the audio amplifier to fail this way. Usually they work or they don't.

Try adjusting your RF gain control. This will often cause this to happen if it is fully on.

Here's a link to the service manual - www.shercoares.org > doc_files > manuals > ica110_sm. This may help. Have you checked both fuses? They should both be about 10A. Use a meter to check them. A visible check may not show the fuses open.

I have an icom 91 and still haven't figured it out. It is easier to use an app and computer and more intuitive.

You need to be a very good technical person with electronics to work on these. The issue is most likely a PLL board issue. You need to be able to troubleshoot to the component level. The service manual appears to be https://www.manualslib.com/manual/738448/Icom-Ic-706mkiig.html

Sure sounds like a "low volts" reboot due to high current draw. Are you measuring voltage at the radio itself, after any connector, fuse or circuit breaker? The voltage (at the set) should be slightly different between low and medium power tx. Use a good meter to confirm this. Is the power supply able to supply the current required at high tx power? Is a current limiter operating? A lead-acid battery in parallel with the PSU might be needed at high power. At high power setting the radio will probably reset faster than a low power input voltage can be measured with a normal meter, so an oscilloscope might be needed to see the power input voltage as it happens (might be very brief). Could RF be getting back into the power supply? Does it happen on both bands? Is the SWR good? Is the earth good? How long and how thick are the power wires? Is there any filter on the power supply wires (close to the radio)? If it's new there will be a warranty if it's a fault in the unit. Good luck :)

Please check the backside jack for external speaker also check your internal speaker.

You've probably already found the answer to this question but doing a search for D104 wiring to ICOM will show you what you need. If the connector is the 8 pin circular one, then the PTT and MIC connections are the same for all ICOM radios.

I would check the charger contacts and make sure that they are actually touching the battery contacts. Also, if the battery is shot, the charger may not recognize that there is a battery in it! You might want to try cleaning all of the battery contacts and the contacts in the radio. These often get corroded and can cause problems.

If the dial actually shows the 40M frequency, then the likely hood of the PLL not functioning is slim. My guess is that the band pass filter for 40M has a bad relay or steering diode in it. This happens more often than not and is a rather inexpensive repair. I have the same problem in my IC-706, except 20M is affected.
