Band Switching Failed
PW1 is on160m. I switch (per hand) to 80m. After pusching PPT, PW1 goes to failure. Switching now to 40m or other Bands and back to 80m, it works. Switching from160m to 40m or other Bands and back to 80m, it works too.Is there any help, on the world ?73 dj4mt

I understand that you are having a problem with your Icom IC-PW1. When you switch from 160m to 80m and press the PPT button, the radio goes into failure mode. However, if you switch to another band and then back to 80m, the radio works fine.
This sounds like a problem with the radio's 160m band. It is possible that there is a short circuit or other problem with the band's circuitry.
Here are a few things you can try to fix the problem:
Check the connections to the 160m band. Make sure that all of the connectors are properly seated and that there is no corrosion or damage.
Try cleaning the 160m band's contacts. Use a soft cloth and some rubbing alcohol to clean the contacts.
If the problem persists, you may need to have the radio serviced by a qualified technician.
I hope this helps!

It sounds like you're experiencing a specific issue with your Icom IC-PW1 amplifier's band switching. The behavior you described might be due to a technical glitch or a connection problem. Try checking the connections, cables, and connectors involved in the band switching process. If the issue persists, you might want to reach out to Icom's customer support or consult online forums for assistance from fellow radio enthusiasts who might have encountered similar problems.
