Mobile Radio Technology (MRT) magazine back issue?
Todd Ellis
Anyone have any old Mobile Radio Technology (MRT) magazines sitting in a
back room somewhere? I'm looking specifically for the September 1995 issue, I badly need a copy or fax of a particular article from that issue. If you have it, drop me a quick line; I'd really appreciate it. Thanks!

They are described as 4 cavities built into one physical "rectangle". Present owner used them on a 440.600 repeater and are supposed to be good to 300 watts. Does anyone have any info on these units?

Your first step would be to read all available information on duplexor technology. The RSGB book is a good source of info. You should also contact a manufacturer like WACOM Products and request all of their literature. They may be reached by e-mail: wacom@... You should scan back through the Repeater-builder list-serv posting for further info. If you have access to inexpensive materials, building your own is an option. Another option is to use two sites spaced far enough from each other that no cavities are required. They may be linked by wire or qrp radio. Please keep us informed of your progress Good luck and vy 73. Bob - W3TGG |
