Went to the local flea market today and picked up a Galaxy DX949 for $20. Radio is hooked to a pyramid 18amp power supply and a imax2000 for testing purposes and has been found to be about 1watt swing to 6 watts low rf power and 5 watts swing to about 17-18 on high rf output. seems radio has been peaked and it is on frequency. This is my question...If I do the p5 p6 channel mod for extra channels do I need to have the radio re aligned after or will it still remain on frequency? I don't want to do the channels until I have the $ if it requires a retune. Thanks to all in advance for all your help.
