Diamond F23A monobander and it works as well
Same luck here with the Diamond brand. While our
local TV station was putting up a new tower which
our club occupied, we ran a UHF repeater AND our
APRS node off of a X-510.
Would it last even 10
Thanks to all of the replies about the UHF Motorola consolette.
As always, your experience and input is appreciated...

If you want to deter innermod you will need to use something like rg-142
which is double shielded, why bother with only having a good shield at
the connector area when the remaining cable will leak in rf like a panty
hose fire nozzle?

Can you advise on the wind shear load and if the manufacturer will rate
it at 120 MPH so it could be used on a commercial site within 5 miles of
navigable water? Do you use an swr meter on your equipment to analyze
reflected power, how broad is the bandwidth and what stability is the
impedance at
thanks that is why I was asking I figured that everyone here would know the
answer and give me good suggestions so I will get some rg-142 only need a

This cable is always handy for other jumpers, get several feet in case
you want to add a filter or pre-amp, it works good on wattmeter jumpers
also.

Hi Kevin,
I will readily admit thatavailable PM exciters can have all sorts of shortcomings. The operative word is 'available' or readily available. While I'll admit that there isn't anything inherently evil with the PM modulation scheme, FM is easy We have manufacturers that have

Hi Kevin,
When we (Scott and I) go to build a repeater for

a radio set that has or needs an FM modulator, it
gets referred to as true

Not real sure if this will help, but Ten mile away may have a loss in
the delay of the audio to the repeater .The distance may causes a bit
of a fuzz sound .

Hi Joe,
I think Bob has finally gone over the edge. :)
It had to happen eventually :-)
I was humorously trying to make the point that'True FM' is amarketing term and that we technical typesought toignore it.The editors of the ARRL Handbooksay so, too- - in my 1996 copy, it's on page
Hi All!
My Weather Spotters are mad at me! Help!
Are there any technical papers out there that describe repeater/radio performance as a function of heavy rain / thunderstorms / severe weather? Where the weather is an attenuation of RF?
Let me describe the scenario.

Theway amicor base repeater is set up from the factoryis
to usede-emphasis and pre-emphasis through the machine. The discriminator
is de-emph'd, run through the control circuitry and then pre-emph'd in the true
FM exciter. (hence the lengthy discussion)
Anyway, looking at your

The primary reason not to run fans 24/7 is dirt, as most radio repeater

Sounds like corona discharge problem like we used to have on a 2-meter

What are you running for an antenna? How is the antenna system
grounded?
It's not unusual to have this effect using a co-linear style antenna at
some sites.

Hi Joe,
It was argued (by Bob @ S-Com) that "If you choose the FM, it must beaccompanied by a preemphasis circuit that covers the entire voice audiospectrum" while you do not on a PM exciter. I will point to the listname and remind everyone that when using discriminator audio, you do NOTneed

Mike how did you do the link? did you
make the micor 1/2 6 meter the other 440? or did you set up a complete two site
ra/rp configuration like in the moto book?
When linking two micor base or repeaters I
use a line driver to the link xmiter.If for full duplex I use a 4 wire
line driver.
Hi Terry,
I would like to say that last years discussions of FM,PM, Exciter wars, emphasis, Fourier mathematics, clipping and limiting was very educational. Wouldn't hurt to have some of that stuff put together in a FAQ.
Agreed, andI've saved the most important messages.. maybe Kevin has,
Hi Skipp,
And we've seen some sloppy engineering in the design of the audio and limiter circuits.What you're saying here Bob... is that you've owned at least one Icom IC-230 at some time in the past. :-)
