Hello
1. Series I must be programmed by eprom, means you have to
create the binary files with your needed frequency(s) and
burn them into a 27C64. Series II have a eeprom and must
be programmed by software and a cable.
2. All UHF and VHF units can be tuned easily for amateur-radio
I have for sale two new CAT RLS-1000B controllers. Here is a link
http://www.catauto.com/rls1000.html that describes what they are and
how they are used in a typical repeater system. I have one additional
controller board in full operation [but not for sale] attached to my
900mhz repeater system.
Hello All,
I'm in the market for a ratchet crimp tool for LMR400, LMR240, RG213,
and RG58. I believe I'll either need two tools or one handle with
replaceable dies.
Anyone have a specific brand or model that they're happy with? If
so, where did you get it?
Thanks!

Hi
I have 2 MSF5000 CXB's and I run the RC210 controller on both. In the program
there is a Kerchunk filterand I have them on. Check your program to cee if you
have that in there. Also I have a MSF 5000 power supply TPN1185A for sale. You

Sounds like they are using a DPL - any of which will have the turn off
code of 134.0 Hz transmitted at the end of the transmission.

John,
You really need to use accurate test equipment, preferably a service
monitor, to verify your frequencies. Unless your repeater and duplexer are
exactly on frequency, your desense problem could possibly be due to the
notches on the duplexer not being coincident with the TX and RX

Yes the proper mobile duplexer can be used and should work
OK, but not with the same performance as a typical higher-Q

The CAT controllers have separate inputs for COR and CTCSS. Perhaps they're
wired to different spots in the MSF SCB and the CAT is set up for OR logic
rather than AND logic, so the CAT is responding to the carrier with the wrong
PL. It's either a DIP-switch configuration or one of the bits in a

Thanks for the help. I believe you are confirming that the problem is

You're correct Greg... that's exactly what it is doing. It gets the tone
from the Four User Control Module, then the Master Decoder passes THAT to
the exciter. My bad for not explaining it correctly.

Try putting a one inch dia, single turn loop on the end of a coax
feed line to a receiver. Use it to sniff around inside the box to find the RF.

John, Make sure that every wire going in to the RX and TX box has a feed thru
cap in series
with it.
Also you might put a few small ferrite beads on each wire as well.

I was wondering the same thing. Has someone added some wiring and subsequently
breached the integrity of the shielding effectiveness somewhere? First thing to
come to mind is controller interfacing and CTCSS wiring.

George,
I plugged in 25 watts at 462.500 MHz and 0.35 uV at 467.500 MHz, and got
67.83 dB of isolation needed, which could be provided by 30 feet of vertical

Check to see if Zone 2 Function 5 is turned on. If on, it could let a COR
signal get to your repeater without having the correct CTCSS frequency decoded.

Chuck, John Bob, Derek, Eric, Mike, JohnB, and Tom,
Thank you all for the helpful suggestions.
The connectors appear to be perfect, and they check out with DC.
The cable on the RX side is double shielded RG142B/U. The cable on
the TX side is not marked with a complete designation. It
Based on my experience, it could also be Pave Paws in long range search mode.

John, Feed thru capacitors look like a peice of wire with a blob in the
middle,
and have a 1/4 locknut on one side. You drill the chassis and insert the feed

mount it tightly with a nut.
Then attach the incoming wires to the outside of the cap.

For a better pickup loop, solder a 50 ohm surface mount resistor in series
with the loop at the end of the coax, and put a few ferrite RFI beads or
clamps at random distances along the coax. This reduces pickup by the coax
