[Repeater-Builder] WTD: Icom RP-1220 Service Manual

[N6KYD]

Hello,
I am looking for a copy of the ICOM RP-1220 service 
manual.
If someone can help me out it would be appreciated. 
I have an intermittent power output. It only keys up at 10 watts occasionally 
and most the time power output is at 1.5 watts.
Can't seem to isolate the problem to a poor 
connection.
 
Sincerely,
Mike N6KYD

Re: [Repeater-Builder] Re: motrac base station conversion to repeater

[Neil McKie]

  Hello ... 

  You mentioned in an earlier e-mail the model number C53MHB-3100BR 
 - I am looking at the manual, Motorola Part number 68P81005E75.

  The main power supply transformer part number. 

  The 524 is the manufacturer number (who made it for Motorola) 
 ... the 7338 is the year (1973) and week (38th) the transformer 
 was manufactured.

  27E ... is a chassis part number. 


  Power Supply Model Number is most likely TPN1068AC 

  Transmitter Model Number is most likely TTD1673AA 

  Receiver Model Number is most likely TRD1742AA

  Continuing ... 

  There are two other specific models of the somewhat similar radio: 

  C53MHX at 55 watts output - 
  C63MHX at 85 watts output -
  C73MHX at 100 watts output -
   All three are "Compa-Station" Base Radio, Continuous Duty 

  C73MHY at 100 watts output - "Compa-Station" Repeater RT 

  Both use the same power supply TPN1073AA and the 24D84948A01 
 Main Transformer 

  Pictures in both manuals shows a blower assembly attached to the 
 transmitter heat sink.  

  The part number of the C5/6/73MHX Manual is 68P81008E60 / 10/24/69 

  The part number of the C73MHY Manual is 68P81008E65 / 10/24/69

Re: [Repeater-Builder] SS-32/5K/Micor

[scomind]

Hi Kevin,
 
I am installing a Comm Spec SS-32 encoder in a Micorrepeater. I am using a logic output from an S-Com 5Kcontroller to key the ground connection to the encoderwhenever the RX COR is active. I need to do this tobe able to link into another system.My problem is when ever the encoder is keyed orunkeyed, it causes the TX to drift off frequency about+/- 900Hz. It apears that this is being casued by a capcharging/discharging. I have tried several differenttone insertion points, always with the same result.
 
I haven't seen many responses, so I'll toss out some suggestions.
 
There is probably a DC bias on the Micor side of the audio connection. The SS-32 has a 1 uF polarized cap in series with the tone output with its "+" side toward the SS-32. When the SS-32 has its ground connection floating, the cap probably sees 12V on the SS-32 side and some other (lower) voltage on the Micor side. When the SS-32 is operating, the voltage on the SS-32 side of the cap may be lower than the Micor side. If the cap operates reversed biased, it can leak or short, causing wierd problems. You could try a 1 uF nonpolarized cap in series with the tone lead to see if that's the case.
 
If that wasn't the problem, and if you have plenty of CTCSS level coming from the SS-32 and can afford to lose some, use a smaller nonpolarized cap (say, 0.1 uF) in series. The lower value will attenuate the level, but may also reduce the drift effect you're seeing.
 
73,
Bob, WA9FBO

[Repeater-Builder] Re: SS-32/5K/Micor

[motarolla_doctor]

Use a series resister AND a 1 uF non polorized cap in series with the 
PL tone going to the Micor. Try to use the same point in the Micor 
that the factory used.

May be the way you are "keying" the encoder, the Micor exciter will 
respond to DC shifts as a frequency shift.

[Repeater-Builder] message error

[ian wells]

Hi guys .I am sorry i haven't returned any messages as my internet 
email sever has stuffed up and i haven't received any messages for 2 
days or more .it is just i checked up on the builder website to see 
the messages i have missed.Thanks to all that replied .The db 
comparrison is being asked as i have 6db antennas on each of my 
470meg repeaters and they aren't getting any real distance over flat 
country .we had 12 db coaxial antennas on our local uhf repeater and 
then changed them to what was called coppercore antenas and we made a 
huge difference to our long distance coverage .The range of the 6db 
isn't bad but we wanted to pick up another 20-50kms at least and 
installing linears on the site wont benifit as it wont improve rx 
range without rx masthead amps so the better sugestion was to install 
higher gain antenas .the sites would be able to be upgraded to 12 db 
antenas if we can find a supplier .the highest we have found is 9db .
but i will certainly take all sugestions into consideration.thank you 

Thank you

[Repeater-Builder] Propogation Prediction

[Fred Seamans]

There are some very high quality computer 
propagation predicting computer programs available that use USGS data maps. 
However these are expensive and only the companies that are into coverage 
predicting in a commercial way can afford them. But they are good.
 
The first paper on VHF and UHF Propagation 
predicting that I became aware of was written by an engineer at GE Mobile Radio 
Department in 1962. It was well circulated and included in their Data File as a 
Bulletin 10003-1 (Abstract: This bulletin is provided for calculating the 
coverage which a certain VHF and UHF transmitter will provide or for calculating 
the power which a transmitter must have to cover a certain area. Such factors as 
path clearance, transmission line losses, antenna gains, and reliability are all 
taken into account for paths as long as 1000 miles). It is written for the 
knowledgeable technician and engineer. The charts and curves contained in this 
work were the basis for most all future computer propagation predicting programs 
of the 80's. For the radio shops and limited users this was a life saver. Also, 
a slide rule type prediction calculator (Range and Transmitter Power Calculator) 
was designed for the mobile radio sales people to use. These were such good 
tools that most manufactures and sales people in the 60's and 70's highly valued 
there use, even "M's" sales people would carry one in their brief 
cases.
 
I doubt you could find the slide rule calculator 
now unless someone hoarded a bunch of them. The Datafile Bulletin 10003-1 dated 
July 1962 could be copied from some of the old timers in the industry. It could 
be of great benefit to answer some of the recent questions that have been on the 
Repeater-Builder mail.
 
Sorry I do not have any extras. Maybe someone has 
some that could be scanned and posted.
 
Fred

Re: [Repeater-Builder] SS-32/5K/Micor

[Kevin Berlen]

Thanks for your thoughts Bob. I have managed to minimize the problem by
doing as you suggested - I put a .1 uF cap and a 27K resistor is series
with the tone output of the SS-32. The frequency still drifts when the
tone is keyed and unkeyed, but now only about 50-60 Hz. I think that this
is acceptable. 73,

You could use my free path analysis tool, rfProfiler-Light, to

site.  



It is not as slick as the expensive programs, but what do you want 
for free!

Re: [Repeater-Builder] message error

[Paul Guello]

Don't assume that antenna gain is the only thing that
effects range.  Antenna height, size and length of
feedline, quality of antenna and how it is mounted and
duplexer quality and tuning all effect range as well
as transmitter power and overall receiver sensitivity.
 High RF enviroments can also degrade receiver
performance.  Take a look at your repeater as a
system,  looking at the quality of all of the devices
as well as the quality of the installation.  One
poorly installed connector can eliminate all the
bennifits from everything else being correct.

Don't forget-Motrac and Micor cards are different! If you have Micor

[Repeater-Builder] Re: Propogation Prediction

[Joe D]

You specify a location using longitude/latitude.  Then you define a 
path either with another point (long/lat) or with a range and bearing 
from the starting point.

The program creates a terrain profile between the two points and 
then, using the Longley-Rice iterative terrain model, calculates the 
path-loss between the two points.

The freeware program uses 10-meter resolution 30-arc-second terrain 
data.

RE: [Repeater-Builder] RC-96 EEPROM

[Rogers, Ron]

Hey folks,

A 6264 is an 8K X 8 CMOS Static RAM..when you unplug it, it loses all data.
The 2864 is an 8K X 8 CMOS EEPROM...does not lose data when unplugged.

They are completely different

RE: [Repeater-Builder] RE: RC-96 EEPROM

[Rogers, Ron]

Tedd:
I have not been following this thread so I have no idea of the whole story 
here. I was simply explaining the difference between the 6264 and the 2864.

But, many years ago someone made a low profile socket for the 6216 and 6264 
chips that had a built-in battery and blocking diode. To give your CMOS RAM 
chips battery backed capability, you simply plugged this special socket onto 
the existing socket on the PC board, then plugged in your CMOS RAM chips.
Could it be someone retrofitted this RC-96 with this mod ??

Hi Ron:

Well that would make sense! My only question arises
is how can the "base" data be loaded into the 6264
if it looses it's data when unplugged? As the RC-96
doesn't have any backup battery, how is the data saved?

[Repeater-Builder] Mitrek element failure

[n1iic Jason Greene]

Hi, all. I have a mitrek that I have duplexed and for some reason it keeps
blowing RX elements. I compared it to others that I have here, and the
voltages on pins 2 and 3 are close, but not on. What are the tolerances of
the elements for the voltages, and has anyone else lost RX elements like
this?

Thanks

Jason

Re: [Repeater-Builder] Re: motrac base station conversion to repeater

[Neil McKie]

  Someone correct me if I am wrong here - I haven't worked on a 
 Motrac repeater in a very long time - 

  Station Logic Module - the diode that connects to pin 3 (anode 
 connects to pin 3) is the Receiver Mute circuit - lifting one end 
 of that diode should leave the receiver unmuted during transmit.

I was once told that Collins radio had standardized S9 to be 50 µV.  That 
would put S1 at 0.20 µV.

The S-meters on most of my VHF/UHF ham gear seem to hit max. indication 
around 10 µV.

RE: [Repeater-Builder] Re: dB compariisons

[W9DHI]

You are correct the standard is 50 µV for a S9 indication, and you are also
right most ham rigs are way, way, way off.  Except for those we build
ourselves.  My HF rig shows exactly S9 for 50 µV.  But that is the only
thing nowadays that could be considered standard.  The S meter is run off
the AGC circuit controlling the gain of the IF amp in most radios.  However
how that is created is different in all rigs and the variation from S9
either lower or higher will probably not be calibrated.

Re: [Repeater-Builder] WTD: Icom RP-1220 Service Manual

[Mark Holman]

If the XMTR is @ 10 W. at 1st. time to key up. and 
then take a dive to 1.5 Watts, being I never seen this unit or schematic, I am 
going to guess ..
 

  A componet may not short until it gets x amt of 
  time the power is present then shorts out or opposite opens up and the pwr. 
  drops.
  Defective power amplifier module.  my reason 
  to think of a RF Module did this before compleatly going out.
these are only 2 thoughts based on 
experience.
 
Hope this helps
