I have modified a couple of "LM" (Linear Modulation) brand ACSB Repeater PAs for FM Use.? It is quite easy.? There is a switching transistor that gets removed and replaced with a jumper - that's it.? If I recall they are about 500mw in for 100W Out.? I did a bench test and made a chart that I put on the PA with the various input/output levels.? The other benefit is if you get the entire repeater you can remove or modify the Exciter and Receiver modules, replacing them with an FM Receiver and Exciter and have everything in the same chassis.? The power supply uses XLR connectors for 13.8VDC supply to the various modules - so just plug and play any 13.8V receiver/exciter.? I have had one of these on the air for close to 10 years with a pair of Alinco DR-235s and an attenuator on the transmit radio.? It works very well - so well that I found a spare and have kept it around.
