Hello Matt Be careful how you tune up the PA in the 700. Here is a fumy story on myself. I tuned up a 700 for 52.525 MHz and the radio put out the rated power with my Bird into a good dummy load. When I connected it to my side tower mounted ground plane, cut for 6 meters, the SWR was terrible. I spent a couple of days checking the antenna and feed line and every thing seemed to be OK. I even made several contacts on 6 meters and every one said the radio sounded good. Later I checked the 700 with a spectrum analyzer and found half the power was going out around 42 MHz! Properly retuning the PA fixed the high SWR and may have saved me an audience with the FCC Wayne, WA5LUY.
