FM Broadcast started out Horizontally polarized. Circular
polarization was later authorized under 2 stipulations. The vertical
plane power can not exceed the horizontal power ERP, and the
horizontal plane ERP is used for the stations ERP. So a station with a
horizontal antenna can effectively

I guess that I do not have much to contribute on this thread
but to me it is very interesting reading. Gary has my sympathy, his
problem is duplicated here. Much of my repeater work relates to a low

Gordon, something worth trying might be low-band.
About 20 years ago, I lived in an area where hams did course communications for
rally events in very mountainous terrain. I remember experimenting one night
about 2am with my partner at the other end of a heavily wooded course, about 12
miles
I would agree that lower gain antennas can make a big difference in some
instances. Higher gain mean more nulls.

Wondering if anyone has found a source for the memory backup

Motorola says the part is obsolete and General Dynamics
is doing some research, but it doesn't sound good.
This one is so dead, that it doesn't show polarity, otherwise

There is one local UHF group that has a back-to-back 6m repeater
just for range extension. The Scom 7330 makes the
parallel/separate link on/off mode real easy (and for up to 3 ports).

Hello all-
I have put together a small repeater with 2 Maxon UHF radios. Here is the
question. Is it better to use the internal ctcss decoder with a line to the
controller or to use an external decoder such as the ts-64? Would there be an
advantage of using one over the other? Thanks for the
Anyone here have an ICOM IC-RX7 receiver and would not mind contacting
me off-list? I want to figure out what is the best way to organize the
memories. The thing has a weird structure.

Hi Folks,
I'm getting pretty close to putting up the machine, and I am looking for a
'real' PA for it.
High split low band Micor PA so I can move it to 6 meters. Continuous
duty.
Already have the rest of the Micor components (RX, cards, exciter, etc).
Please respond off-line.
thanks!

Thanks to all who responded. With their help, I was able to locate a
replacement. It seems they have upgraded the battery from a NiCad type to a
nickel-metal hydride type. See link below for source.

Thanks again,
I completely agree! Back in the late 60's, I was Chief Engineer at WLRW-
the first FM station in the state of Illinois to broadcast in stereo- and
this was in Champaign-Urbana, not Chicago! The transmitter was an RCA
BTF-10D which fed five Andrew Vee antennas and five Gates Rings, giving

Greetings. I'm the trustee of our local club's 2m repeater. It's NE of the

needed for T147.210 R147.810), and arrange the elements on the
