Batboard

Hello it has been about 20 years since I last did this modification.

Could someone please tell me where to find U551 on the Maratrac radio Your help is greatly appreciated. Thank you

Go to http://www.repeater-builder.com/motorol ... index.html
In the manuals section, get the first one, VHF low band service manual.
On the second to last page is the logic board, someone was nice enough to mark U551.

Thank you.
