Ok Scott, thanks for the info. Ill see what I get out of the exciter connection before the PA and see what it's at.

Thanks. > > Kevin > K2KMB > Hi Kevin, That is a very good question. I didn't try adjusting the PO as it fell right about where I wanted it. I received the service manual and schematic for it yesterday and had just a few minutes to look it over last night. It would appear that the 1-10 watt version is basically what I have made, the 45 watt PA up through the driver, which is now the final. Same transistor but a few capacitor value changes. If this is the case, Motorola rates this as a 1 to 10 watt radio. I would think you should be able to lower it to 1 watt. You may have to go back a stage to get your 500 mW. I seem to recall someone else's post that indicated thay had used the input to the PA module which gave them 700 mW. You might want to look for this post. 73, Scott Madison, WN1B Yahoo!
