Just purchased the VHF600 and Galaxy 5225-XT antenna.<br /><br />Having problems with reception. When I turn on the unit it receives perfect for about 5 minutes and then cuts out. Lights are all on. Squelch will go to static (noise) and then I can back it off.<br /><br />This happens every time. Apprx 5 minutes into it being ON I lose signal. Mainly tested on Weather Channel. <br /><br />I have the unit connected to my GPS (shows location), unit breathes well (not cramped), PL-259 seems to be connected well (not sure how to test other that the fact I get great reception for 5 minutes).
