[Repeater-Builder] Re: Radius R100 DPL to PL Change

2007-09-09 Thread Eric Lemmon
Mark,

The i20R is marketed as an on-site repeater controller for various Motorola
and Kenwood commercial radios.  It is capable of transparently passing
either TPL or DPL, or it can strip and replace TPL or DPL with the same or
different codes, and it will handle up to ten users.  The i20R is
manufactured by Instrument Associates of Memphis, TN.

The i20R front panel and cabinet is identical to the Gai-Tronics IRC3000A
repeater controller, but the rear panel connector layout is slightly
different, and there are some differences between the PCBs.  The IRC3000A
sales brochure is here:

www.gai-tronics.com/literature/lmrlit/gtc011105rev11-05.pdf

The IRC3000A service manual is here:

www.gai-tronics.com/products/manuals/43004028a.pdf

I believe that the i20R and the IRC3000A have a common heritage, but which
is the parent?

Steve and all...

I have the instruction sheet for connecting a Zetron to an R100 digitized at
home. Also, I have the R100 manual in digital format as well. 

I'm not familiar at all with the controller you mentioned - but unless it
does its own encoding/decoding for DPL, you're not going to be able to get
your R100 to make the switch. (That is if your R100 is PL only at this
time. They came one or the other, but not both.)

The unfortunate thing is - I suffered a flood about 2 weeks ago and lost my
computer with the database on it as a result. (Motherboard or power supply,
or maybe both, I'm suspecting at this time...) :-(

I know others have downloaded these items from me in the past - maybe
someone here can repay the favor by forwarding that to Steve on my behalf?
Unless you're not in a huge hurry to get this thing working, Steve. I'm not
sure how long it will take before I can resurrect my computer at home...

Thanks!

Steve,

Anything is possible, but the manual for the i20R controller does not
include specific hookup instructions for the R100. However, it should be a
fairly simple task to translate the instructions for the GR1225 or GR300 to
match the pinouts of the R100.

The i20R controller is a nifty piece of hardware, since it includes such
nice features as CWID and low-battery alarm tones, but it is a bear to
program. Here's what you need to program the i20R:

HVN9085B RSS, currently $310
HKN9217A RIB to radio cable (the same as used for most Radius mobiles)
Motorola Radio Interface Box (RIB - ditto)
6880904Z40 i20R Service Manual, about $25
6880904Z55 i20R Software Manual, about $30

I just got a Motorola i20R controller. Is it posable to wire this to 
a R100? Would anyone have the pinout for a i20R?

 Hi Steve,
 
 The change requires you to change out both of the processor 
chips in 
 the TX and RX radios. There is also a few part changes of 
capacitors 
 and resistors. Then you need to do the software change and re-
alignment.
 
 It is strongly recommended that you just disable the internal 
DPL and 
 add a Com-Spec 64 enc-dec externally.

OK - if someone can provide him with the interface sheets or the R100 manual
he should be able to connect it just fine, then.  I only wish I could..

Thanks for the info Eric!

If you haven't tracked down a manual yet, you might watch ebay. 
Motorola manuals show up there fairly often.

Until you get a book, this may get you going:

MCR100 Alignment

With the RF board positioned so that the legends are readable, the
receiver coax enters at the top left [J1 labeled RX].  You will see
three groups of cans with screw adjustments.  Left to right these are
FL1, FL2, and FL3.  FL1 and FL2 are the RX RF filters.  FL3 is the
injection filter. 

With the cover off the shielded compartment, C201 is at the top right
of the upper half of the compartment and C221 is at the lower right of
the upper half of the compartment.  R163 is to the right of the SL
legend in the top part of the lower half of the shielded compartment.
[TX rf only]

Transmitter:

VCO Adjustment.  
1. Connect a DC voltmeter [input impedance 11 megohms or greater] from
the steering line test point [SL] to ground.
2. Key the station.  Adjust TX VCO control C221 for a reading of 6 VDC.

Output Power Adjustment.
1. Adjust Output Voltage Set control R8 on the power supply regulator
board for an A+ equal to 13.2 VDC +/-0.1 VDC.
2. Key the station and adjust High Power Set control R453 for 25 Watts
[25 Watt stations]

[there are several more steps in the book that can be followed for a
complete alignment]

Reference Oscillator Adjustment
Key the station and adjust 2 PPM Frequency Control R163 [on the
transmit RF board] for the exact transmit frequency +/-100 Hz.

Receiver Adjustments:

VCO adjustment. 
1. Connect a DC voltmeter from the steering line test point [SL] to
ground.
2. Adjust RX VCO control C201 for a reading of 6.0 VDC.



After you set your RX steering line, put your voltmeter on the local
oscillator test point [LO - near FL3].  Tune FL3 for maximum [2.5 to
3.5 VDC typical]

Then you can tune the front end filters FL1 and FL2 for best SINAD. 
Finish up by fine tuning FL3 for best SINAD.
