Re: [Repeater-Builder] Can you change Motorola R100 from DPL to PL?

2005-12-23 Thread Kevin Berlen, K9HX
It has been a while, but you must change the processors in the TX
and RX strips, as well as some other components. It is not too bad
of a job, but I don't know if the parts are still available or not. Both
PL and DPL units can run carrier squelch. It might be simpler to program
your repeater for this mode and then install aftermarket tone or digital
squelch boards.

Chris,

I have several R1225 repeaters in service, both VHF and 
UHF. I tried using one of them with an i20R controller, but I found that 
the loss of the reverse burst STE to be unacceptable. So, all of them are 
now running with the built-in controller and doing just 
fine.

I'm curious: Why would you want to connect an 
external controller, when there's one already inside the 
radio?

Re: [Repeater-Builder] Duplexer tuning with MINIMUM tools

2005-12-23 Thread Neil McKie

  One time, I used a Mastr II Receiver to tune one notch ... and a 
 Motrac Receiver to tune the other notch. 

  For terminations, I had a GR-874 20 dB pad on the unused port and 
 GR-874 10 dB pads on the ports being tested.  Also used double 
 shielded 50 ohm jumper coaxial cables - with GR-874 connectors.  

  The use of the 20 dB pad on the unused port worked quite well as 
 the return loss in 40 dB.

RE: [Repeater-Builder] Wanted - MSF-5000 UHF Duplexer Cable

2005-12-23 Thread Bob M.
They're definitely rare. Not many people pull them out
when stripping a station to its component pieces. I
have one in a working station. While I could measure
it, there's the actual splice box that joins the three
pieces of coax, and I don't know if there's anything
magical going on inside besides one solder joint.

I don't know if it could be duplicated with a common
TEE connector. I do know that the leads between the
output of the filter/duplexer and the TEE, and the TEE
to the antenna jack on the side of the cabinet, are
quite short, maybe one or two inches each. The line
going to the receiver is much longer as it has to
snake its way around and allow the RF tray to slide in
and out.

The location and color of the band at the splice box
determines if the unit is used for tx freq  rx freq,
or tx freq  rx freq, and also the band split:
403-438, 438-470, 470-512. I have a sheet on it
somewhere, but it doesn't specify the cable lengths so
you could make your own. I doubt the lengths are
critical, due to the wide bandspread of the harness.

If you don't really need the internal filter/duplexer,
you might be better off with an external Bp/Br
duplexer; at least it wouldn't need that expensive TEE
cable. For the cost of buying a new cable from
Motorola, you could almost buy a decent external
duplexer. Plus the tuning would be a lot easier.

RE: [Repeater-Builder] R-1225

Jay,

It's true that the R1225 internal controller won't respond internally to a
knockdown command, but I use an NHRC-Remote board to respond to a DTMF code
on the input which pulls down the Repeater Knockdown pin on the accessory
connector.  That, coupled with the timeout timer set for three minutes,
gives me the required control.  The same remote board can also be used for
PL selection, channel steering, or door lock control.  It's basic and
simple, but it works.

[Repeater-Builder] Re: Can you change Motorola R100 from DPL to PL?

2005-12-23 Thread Gary
Unless you can find someone out there with a kit, or find both RX and 
TX modules with the PL kit already installed, you are better off going 
with an outboard module such as the CS TS64, etc. The kits are NLA at 
Motorola. I saw a kit on Fleabay, the other day, but I believe it was 
a DPL conversion kit. The kits are very rare anymore. It involves a 
programmed chip or two, plus a few other parts, so you cannot go out 
and make your own.

RE: [Repeater-Builder] Duplexer tuning with MINIMUM tools

2005-12-23 Thread Joe
My first set of 220Mhz duplexers (homebrew) were tuned up with an HT and a 
box with a 50 ohm resistor, diode, and capacitor in it.  I fed the 
rectified signal voltage to a oscilloscope.  I then tuned for either 
minimum or maximum voltage on the scope, depending upon if I was tuning the 
notch or the pass.

Where there's a will there's a way.  Maybe not the best way, but it worked 
well enough to get the repeater on the air with reasonable performance.

I once used a 10 Watt freq agile transmitter and wattmeter to set pass freq
and a bearcat scanner and a tunable variable frequency generator to set
notch on a wacom 678 UHF duplexer.  Tuned notch for noisiest signal into
scanner.
