Ralph,
Before you make a decision on your supplier, please read the following

Unless you have a testing laboratory
Another respectable option: do the following:
I downloaded the manual on the CAT-200 and looked
The CAT-200B has the ability to do de-emphasis, but, it's not as simple
as flipping a dip switch; you must install a capacitor for adding
de-emphasis per port.
C10 is for RX#1 and C11 is for RX#2. These parts are listed as
optional on the
Well everyone, it's DONE! The N9WYS 900 MHz repeater station is finally
built and ready to go on-the-air!!
I want to thank EVERYONE here who was so patient, understanding and helpful
during my arduous journey in building this machine...
The final configuration is as follows:
Glenayre GL-series
Thanks for the help. Need a little more clarification. I have never
used one of these before, so I don't want to blow it up. I have a
chip that is stackedI suppose this is the one. I took it apart
and wouldn't you know it, I managed to turn the chip socket with the
smaller chip inside
Joe,
I don't see a connection between how long the order takes and whether or not
the crystals are flawless. Knowing that a properly-made and -compensated
crystal takes time, I'd shy away from a company that has a very short
turnaround.
Perhaps the longer turnaround time with orders at ICM is
On the CAT200B manual I have, page 6-2 tells all about
adding C10 and/or C11, and the value they supply is
0.0047uF. Don't chastise them so hastily. Engage eyes
before shifting fingers!
They probably designed the audio stage to reject
sub-audible tones. The audio response is perfectly
adequate
My last few crystal orders went to West Crystal (www.westcrystal.com) in BC,
Canada. In the 80's and early 90's I ordered from Bomar exclusively, and
then started running into problems and switched to ICM. I was very happy
with ICM for the next ten years or so, but their prices started to get
I am using a CAT 200B controller on a 222 mhz repeater made from a Micor mobile
that I converted to 222 mhz and a UHF GE Delta-s for a remote base radio. I am
using discriminator audio from both radios with the 0047uf C10 and C11
installed, everyone says that the repeater audio is excellent.

Not trying to sound too obnoxious here, and this is just a general
comment, not necessarily meant to reflect this particular controller
or setup but...

Fine. If they have to take longer to provide the product, don't tell me
delivery will be 4 weeks than take longer.
The apology letter I received from them said nothing about a backlog of
orders.
As for the flawless part, I did not directly relate that to the time. I
said I went with them due to
Thanks for the research Kevin. This Cat 200 is a good one to start with. I
did not do the original install, so I will check the values. Mr. Lightning
as not been good to this site, so this is the 3rd repeater the controller
has been on. The other two were Micor Mobiles. Hope to get the associated

Just out of curiosity, how long were you quotes, and how long
did it actually take?

Be sure to align pin 1 with the socket and with the Dallas Semiconductor
Battery Backup and the memory chip and plug them into U15. My units do not
even have sockets installed in U16, but I suspect the two locations are pretty
much in parallel except for an address line to give the unit more
Depending on the type of Dallas chip you can add an
external battery to them. There are instructions on how
to do it on the internet. I ran across them when looking
for a way to fix a problem I was having with the bios on a
Sun server. A little search on Google might bring you
