144MHz PA

Projects

My 144MHz PA is based on two pallets, each with one pcs. LDMOS type MRF141G from Motorola.
After a lot of problems my 2m PA is finaly in top shape, thanks to OZ1LPR.
Putting 25W in, taking 500W out. By doing so compression remain low, and stations near me also have a chance to hear other stations but me. In 2012 I purchased three pallets more, and plan to use one for driver to 4 pallets. It should give me a clean 1kW signal on 144MHz. Only problem is how to find room for 5 pallets in the same enclosure. Looking forward to finish the project.
