Jeff,
To my ear, it sounds like normal multipath (picket fencing) on the mobile
signal may be triggering the pops, and they're being worsened by audio coupling
somewhere that's passing too much low frequency audio.
I've had radios that sounded like that, and also popped badly on squelch
Jeff,
I agree with Jim's assessment, that the popping might be due to an
over-deviated signal coming into the repeater. Many imported radios built
for the Amateur Radio market are delivered with the CTCSS deviation much too
hot and causing the total deviation (voice plus tone) to exceed 5 kHz.
Jeff you mentioned 220 ACSB.
I have a question you might be able to answer about Securicor equip.
Contact me off list when you get a chance.

Hello Jeff
First--There is nothing wrong with the CAT-1000 controller that comes with the
Kendecom repeaters---It is a perfectly good controller capable of doing almost
everything imaginable well.
Now---There were a batch of Kendecom 5000 repeaters made that had a problem
built in. The
After spending so much time chasing the DB-224JJ information down
I'd probably buy and use something else, which I have done. I'll
keep the JJ Model in my mind as I pull down a few more of the
Nationwide 220 ACSB Trunking Systems in the spring time.
Knowing full well that Skipp may fight
I believe 100mw is the exciter PO. There are several amps that will do.

Has anyone had any experience taping directly into the output of a GM300
to drive an external amplifier, bypassing the GM300 PA completely.
Any idea on how much drive one might

First. I have the preamp in my MASTRII now and it's still
not performing the way it should. I think that I may be
having some of the receive issues mentioned on the site
maybe wisker growth. What is the best way to determine if
the receive side is working to full potential?

I am looking for some one in my area to help build a Vhf repeater. The
help would need to be hands-on.Any one that can help please let me
know.

Has anyone tried using the Austin antennas that were built for the 200Mhz ACSSB
system on the ham band? There are several of them lying around on the ground
here in Connecticut. Actually, I was just offered the ACSSB equipment,
including the combiner, if I take it all away. I can use the

Hi Jeff,
I have experience similar noises on my Micor repeater that turned out to be
a old antenna with minute cracks in the aluminum causing arcing during
transmit that the receiver was picking up. I changed out just about
everything but
the antenna and STILL HAD THE NOISES!. The

The person Paul refers to built 2 of these antennas, from scratch,

duplexer. Performance remains
Does anyone know if the VXR-1000U be easily converted for use on

If so, is the method documented somewhere?
Does anyone have any experience using either the VXR-1000V or
VXR-1000U for an Amateur Band repeater?

BTW, reflecting on a discussion about the Midland 13-509 radio for

built at the same time as the antennas. I know this is the kiss of death,
