Motorola PT-400 Help

Post by WA7IEP » Sun May 24, 2020 10:10 pm

Hi:
I'm looking for help with replacing crystals and tuning a Motorola PT-400. It has the low VHF frequency split, and is currently set for 143.025 MHz. I have crystals for the 2M band. I don't trust my soldering / desoldering skills and have to real RF test equipment to properly tune the radio even if I could swap crystals. I was wondering if anyone has experience working on these or knows of someone who does.
Thank You,
Gary / WA7IEP
