Hello amateur radio operators, I picked up a K1 recently and noticed that it’s audio from the internal speaker is quite low, even with AF gain wide open. I did ensure the attenuator is off as well as non-typical operational settings. From there, I did read in the manual that a procedure is necessary to troubleshoot (peaking the band filters, etc.) Has anyone else had similar issues, before I go bumbling around in the radio? By no means am I deaf yet! But it’s noticeably low.
