Are you sure it's not just causing some odd
propagation and they are seeing a distant station?

Glad you mentioned weatherproofing. I should have, since I'm picky about it.
Tape --- Scotch 33+ is your best friend. Don't use an off-brand. I buy it by
the box. It's never let me down.

Yes, I agree. Scotch 33+ is the only way to go. I have been
using it for years.
Outdoor coaxial cable connections, I cover the Scotch 33+ with
two layers of Scotchkote - a sticky substance that comes in a
can with a brush.

Thanks for not YELLING Coy, but you missed the part about only one side working the 5 volts, I need both bands to have a positive voltage. I got that from my volt meter, THE MANUAL DID NOT SAY ANYTHING ABOU THAT. And nope, a clean clear site, it's all mine, no other transmitters to worry about.
>From tornado alley in Norman, Oklahoma:
I remember reading many years ago about a technique of placing your
television on an unused channel and darkening the television with
the brightness. A nearby tornado would be indicated if the screen
brightened. I probably should Google this
Michael, I read that as well, and it
was channel 2 that was indicated and of course you
must be on an outside antenna. As I recall the
tornado created quite an electro-magnetic
field around 54 - 60 Mhz. (Ch 2)

OK, here's the deal about tornado detectors. This info circulated in the
ESDA wx spotting comunity back in the late 60's. Don't know where it
actually started.
Turn TV set to unused mid channel (5, 6. etc.) Set contrast to max.
Back off on brightness until raster (picture) just
Hi
is there a fr,ee computer prog to work ot the
lenghts of coax to make notch filters ?. Iam starting to put together a 6mtr
repeater here in the UK, and need to play with coax to make a duplexer, can't
afford the prices of a ready made one.
I don't fancy using heliax, OK it works, but

Maybe the reverse of that. Brightening indicates less signal in analog TV.

I put up 4 new DB224E last year and the spacing between elements varied
considerable between elements on the same mast and from antenna to antenna.
All of the hardware needed additional tightening most

I wrap the connectors and a small section of the
hard line each side with quality electrical tape.
Follow the wrap with Scotch 133 rubber tape or
the common antenna connector putty - putty/tape
of choice.
Wrap the putty with another layer of quality
electrical tape, your choice of width.
That's what I remember too, except that when you adjusted
the brightness, you did it on an unused high band channel, then switch to the
lowest unused low band channel and watch. The lightning gives the characteristic
"band flashes" on the screen. The tornado supposedly produced a constant

I've seen the same symptoms occur when an inexpensive multi-band ham antenna is
used, especially when the antenna is fairly close to the repeater and
single-shielded coax feedline connects the duplexer to the antenna.
Try using a good, broadband antenna that is known to perform well in

Try setting one side as the control (CTRL)band and leave the other
side as selected with (PTT) try that. I'm not sure if that will work
but it's worth a try. something else, you might be able to get a
schematic and catch the audio switch for the squelch circuit. That
should work, you may have to
It's easy, a ELECTRICAL quarter wave length open stub or Half wave
shorted stub will give you a DEEP notch on the order of 25 to 32 db.
The electrical length is the mechanical length multiplied by the prop
factor. It's easiest done by cutting a bit long and pruning to length

Hi
Thanks for info. Yes I appreciate what you say.
I have used coax as filters on VHF PMR ie 160Mhz
and they worked fine. Will give it a go

I thought that would work, even tried the locked band but that did not work. So I decided I am just going to get some squelch circuits and use them. If I had more time I would build them, but time for me is very little and when I start if I don't finish and I come back, I forget where I am at.
I have been installing some 40 watt 470-480mhz
repeaters with diplexerswith 6db antenna ontop of a 9 meter mast
with no problems.
I am wondering what
i will face if i use a low mast ,say 3 meters above a fridge with a 50 watt
repeater and 6db antenna..If i run into decence i will have to
