Hi Guys,
We are, in my little HAM-community in Gyor, Hungary, Thinking to start
repeaters. We have surplus radios, aerials, but the big Enemy is the
duplexer (cavity filter).
We need homebrewer's technical docs how to build a good cavity filter
for 10, 6, 2 m and 70 cm bands.
Can anybody help with some technical literature on any other ideas?
Thanks in advance
