I would like to know if there is another vendor. I replaced one in a T2X with a part from MFJ to cure erratic readings without success. -de NI0K -John ________________________________ From: [email protected] <[email protected]> on behalf of Kevin McQuiggin via Elecraft <[email protected]> Sent: Wednesday, September 3, 2025 9:59:05 AM To: Andy Durbin <[email protected]> Cc: [email protected] <[email protected]> Subject: Re: [Elecraft] OT - Ham IV position pot repair Hi Andy: I bought a new pot assembly that is a drop-in replacement in the rotator. That was way easier than redoing the winding. I forget the name of the place, but there is an online shop that sells them. The new one worked perfectly and has been in service for 4+ years. 73, Kevin VE7ZD/KN7Q > On Sep 3, 2025, at 10:43 AM, Andy Durbin via Elecraft > <[email protected]> wrote: > > Lots of very experienced people here.
