I have a brand new ParaDynamics 6000 meter (3 Window 5K reading one) it's a couple of years old, that hasn't been used since new, took it out of the box to check it out, the SWR Meter isn't working, the power, modulation windows work fine, I called the number on the paperwork that came with the meter but, this number is no longer in service, any ideas where I can get a replacement SWR meter for it would be appreciated or a number to contact that would have the part I need to fix it, thanks.
