Sowz we don't be stupider

The .82 Repeater

This isn't our tower but it's a great picture

This isn’t our tower
but it’s a great picture

The first repeater was put up by Leo K0JIU who lived on South 1st in Co/Blfs.
He actually gave the first one to the Omaha club, .94, and made a second one
to experiment with, .82, and put the receiver on the blue water tower near
S.A. high school on Gleason Ave. Back in those days you made repeaters yourself,
often out of used Motorola stuff because it was reliable and fixable. By the
time I showed up, Leo had replaced the original tube type with a transistorized
receiver on Gleason, and updated the transmitter to a 500W 2 tube Motorola
at his house. They were connected by audio (and a 150V powered current) on a
phone line between the sites. We’re currently using a Yaesu 7000 box, TXRX
cavities, and CommSpec antenna just North of Simms St 3 miles East of
downtown.
.
We own a new dual band Yaesu Fusion combination analog/digital repeater bought
(cheap) for $500. Also a set of cans bought (cheap) for $100 from John AB0VX.
We could put up the new repeater tomorrow using an antenna at somebody’s house,
but ultimately intend to put it on UHF out at McClelland IA.
.
These people have joined the club helping to pay for everything. (They used to
get a newsletter, but we don’t currently have an Editor, just a few poeple
who put up stuff on this site.)

So here’s a pic of the real repater antenna out on Simms.

North end of Simms St

Our 146.82 repeater antenna is located 3 miles NE of downtown Council Bluffs atop a 185 ft
cell tower in a large empty lot on the North end of Simms Street. It’s 1 of 3 antennae at the
top, formerly hung upside down below the top mount until they revamped the tower and put ours
at the top with the other two. The antenna itself is a 4 bay folded dipole with 6dB gain set
vertically along a 20 foot pole. (2 dipoles give 3 dB gain, so doubling that, 4 dipoles, make
6 dB gain. How does your hundred dollar omni that’s 8 ft long get 5.8 dB? Answer: It doesn’t.)
.
The repeater itself is in the Sheriff’s half of the cell phone building, a Yaesu 7000 with
both receiver and transmitter in the same box. The 2 connectors are cabled to a network of
4 resonant cavities and associated phasing cables so that the transmitter does not affect
the receiver even though both use the SAME (this is magic) antenna (thru 200 ft of low loss
hardline coax).
.
The Yaesu has a built in controller, but we’re using a separate much fancier one to do ID,
timer and other functions. (Get on the repeater, ID, and then hit ‘400’ on your touch tone
pad. It’ll say the time, and if anyone bothered to set the clock in the last year, it’ll be
halfway accurate. This also tells you that you’re full quieting. It won’t decode noisy sigs.)
.
Even though we don’t pay for electricity or tower space, the stuff cost a lot and needs the
occasional updating or service. Kilobucks each for repeater and antenna, and near double
that for the cans (4 cavity set from TXRX). Paul WB0GXD sold us the hardline at a greatly
reduced price due to a bargain he found. Care to join the club or donate? Ask.
