Same thing with the Micor 223/224 MHz conversions. We simply used bricks with trailing low pass filters. I'm checking to see what type of docs I have around for the pa sections.
There's a really well done/built linked 223/224 linked system on the west coast called the Condor System. You might search the web for the conversion information related to that equipment. I based one of my last brick projects on that same circuit... the hard part is trying to find all the proper parts (caps rated for vhf with a decent D-factor) at decent prices. A few years back there were a modest amount of small size Milcom 220 Mhz hybrid pa's on ebay. Another source of 35 watts on 224 MHz if you can find them still. s. > Nate Duehr <[EMAIL PROTECTED]> wrote: > Everything I've read about converting MASTR II PA's from VHF > to 220 doesn't look too good. > > I have heard rumor that moving a MASTR III PA might be easier. > No desire to hunt for one and try it, though. > > Most of the MASTR II 220 conversions I've seen on-air took a > "brick module" 220 PA from RF Parts and fed that from the > converted M2 exciter, for around 25-35W out. > > Nate Duehr > [EMAIL PROTECTED] >
