RE: [Repeater-Builder] Several MSF-5000 questions

[NC4AB]

Derek -

I'll see if I can help with your first question -

While I'm not that familiar with the CXB series, the older analog (CLB) MSF
repeaters weren't recommended for any PL tone above 192.8 hz.

The cut off frequency for the low pass filter on the PL circuit was around
200 hz, so if you programmed a PL frequency above 200 hz they will work but
will take a very long time to decode.

Sounds like this is your problem.

[Repeater-Builder] Part ID

[Dan Hancock]

I have a plug in module that I got with some
Spectra-tac receivers. It is similar to the metering
module for these units, except that it has no switch
on it for the various functions. It has only a meter
face, a speaker on/off switch, and a meter +/- switch
on the face and a speaker on the board. It has part
number ZLN6133A stamped on it. 
Anyone who can tell me exactly what equipment this is
for and what it meters (since there is no selector)?

[Repeater-Builder] Re: Community Tone panrl

[skipp025]

Re: CSI and Comm Spec tone panels. 

Both are great panels Joel, I have many of both 
types and brands in service. I wish I could say 
one is best, but they are both great working 
units.  

But... If you buy a used TP-3200, open it up 
and make sure it has the reset timer daughter- 
board installed.  There is a glitch event in 
the tp-3200 tone panel software, which causes 
it to lockup in certain conditions.  The board 
is an easy spot, a two or three inch square 
mounted on double sided tape (most of the 
time).

Comm Spec will send you a free timer board if 
you don't have it inside.  The board is a 3 
wire connection, doing a complete reset about 
every half hour.  

It took some time for the TP-3200 tone panel 
software bug to appear. Under the right conditions, 
the panel will lock up and require a hard reset. 
Comm Spec has been quick to come up with a 
"fix" that works pretty well. 

There are a large number of these panels in service 
without the revision timer board. Thank goodness 
everyone listened to my suggestion and left their 
hardware timeout timer modules installed. :-) 

If you think you might ever do anything related 
to commercial two-way radio, I might lean toward 
the other CSI Tone Panel, the model TP-163

It has one really neat feature that could be 
used for an amateur linking and commercial 
radio project. 

There is an optional connection (and software 
option) for paralleling the tone panel with 
another panels TX output line.  This is a tx 
busy detect line that can be used for a dual 
tone panel or radio linking project. 

The busy sense line option monitors a line 
for "busy" logic.  There are many handy uses 
for this function, especially in commercial 
radio systems running dual modes.  

This is the only main function the CSI TP-163 
has over its brother the tp-154 or the CSI-3200.

Re: [Repeater-Builder] UHF Micor RX

[RSGilmore]

Aside from others' suggestions here ...  consider the possibility that,
for linking purposes, being somewhat deaf may not necessarily be a *bad*
thing. 
There might be some benefit insofar as keeping some trash out, if you can
satisfactorily make the path as is, etc, etc.  YMMV.

..and, not to overly nitpick -- seeing 446.500  and thinking "Why not
43x.xxx  link-band ?"   

Enquiring minds, and all that...

First of all, *some* Micor UHF receivers are just plain deaf.  I have 
found that the sensitivity of them are not as consistent as the VHF 
models that 99% of the time end up being within a few dB of one 
another.  The first thing to do is replace the channel element with a 
commercial frequency and test the receiver at 45X.XXX and see where your 
receiver is at.  If it is deaf on the commercial band, there may not be 
much you can do but try another receiver.  Typically, a properly tuned 
barefoot (no preamp) UHF Micor 'just makes' book specification of -116 
dBm for 12 dB SINAD, and it is not at all common to see them a few to 
several dB worst than that.

Make damn sure you tune them per the instructions in the manual 
religiously.  There is no better procedure than the one in the manual.

If you find that your receiver is fairly good in the commercial portion 
of the spectrum, you could do the modification suggested here, even 
though you are above 445.000:

Sometimes it helps.   If the receiver is not part of a UHF Micor 
mobile transmitting system where the injection 'side' matters, you could 
also try the other side injection, as sometimes that helps too.  At any 
rate, don't expect your receiver to be any better on the ham band than 
you see at the commercial frequency, and a little worse is to be expected.

I just converted two Micor UHF receivers for someone.  Both were 
operating below 445.000 after conversion.  Before conversion, they were 
'quite good' in the commercial band at -117 and -118 dBm.  They ended up 
at -116 and -117 respectively after the conversion mentioned above.

Hope this helps...

Re: [Repeater-Builder] UHF Micor RX

Kevin,

Did the RX have rated sensitivity on the original operating frequency?
If not, Q104 may be bad.
If so, try replacing C138 with a 4.7pf.

I prefer the TP-154. It's been so long since I've done the

I can say that I've never had a problem with any of the 154s.

I'm wondering why I'm hearing them on the HAM's 900 band.

I'm using a receiver that is designed to go from 100 Kcs to 1500 Mcs. Its a

Re: [Repeater-Builder] Re: New-be and question(s)

[Steve Grantham]

Vester,

  I can understand folks wanting recognition, and I can understand you
wanting to promote 900 MHz.  However, my point was that any mention,
disclosure, or announcement would naturally have been in the
organization's official minutes, in its official printed vehicle, and/or
on it's official web site.  If you want to go back and check the
minutes, I am confident that you will find an appropriate mention.

  I find it commendable that you are endeavoring to recognize these
gentlemen.  However, I can't recall any particular time when there was a
broadcast of recognition via any external means for anyone else either. 
There are a lot of other folks who have contributed through their
efforts in different ways, at different times, and on other subjects.

  One day, something over a decade ago, I woke up, checked out of the
hotel, and while in transit to a job site, I read in the newspaper that
the company I worked for had been sold, and that was the first I had
heard about it.  Obviously, I too would have preferred that someone
close to the situation had directly notified the gentlemen you name, if
in fact the hadn't.  However, whatever happened, stuff happens.  That's
all I have to say about this.

73,
Steve

[Repeater-Builder] please help ge mastr II exciter- decode board numbers

[randy kisthardt]

I just got a mastr repeater but the combo number is missing 
the reciever is working and looks normal  46?.???  the xmit light
comes on 10 volt card  with active rx  (its trying to work)  the
exciter is not working  (no crystal)
It has a cable comming out the top of the icom (external controll?)
I was wondering if some one could tell me what i got and if i could
use 
it to build a 440 mhz repeater for ham use. the numbers are as follows
pa circut board # pl19d4171166g2 heat sink #pl19d4173883g  is this a
regular  460 mhz pa?  
exciter  # pl416859g8 rev f  Its missing t101 & 102 as compard to the
picture on inside of lid. cable out top of icom.  will this work with
a regular icom?  or do i need to buy a exciter along with a icom?
the reciever is working and i think its a regular 460 mhz the number
is pl19d417075g2 rev a
please advise if i can keep exciter and or the pa or if the rx is ok 
I cant find much abought it with just part numbers. i was hoping
sombody knows mastr II's numbers  and could help me  dont want to buy
what i dont need 
thanks a bunch

Re: [Repeater-Builder] FAA Paint Removal

[Chuck Kelsey]

I'll stick with my original suggestion - paint it 
black with some Krylon. Since it's your tower, you only have to answer to your 
wife and the municipal inspector. If the paint starts to deteriorate, you could 
always have a feedline replacement fund started so that if you need to do 
something in five or ten years, you'll have the funds to change it 
out.

Actually, Ralph and Lin first learned rather indirectly, via a 
2/11/02 email to the GA repeater owners reflector, that their plan  
had been adopted by SERA during the previous year. This email made 
no mention of Ralph or Lin. Please see AR902 MHz message 1064, dated 
2/16/02. I researched this fairly well on AR902MHz and elsewhere six 
months ago. If there was ever any disclosure beyond this email to GA 
repeater owners, I apologize for missing it.

73,

Vester N8EKA

Re: [Repeater-Builder] FAA Paint Removal

[W8KT]

OK, I should have been more specific. This is going on my tower. It is
a 140 foot length of Andrew 1 1/4" hardline. I have been very careful
in the components used to avoid any "problems". The tower is Pirod as
is all of the hardware. Lightning rod, "T" bars for the snap in
hangers, etc. All grounding is #2 stranded with 3 ground rods per leg
all tied together. All cables grounded. Polyphasers on all lines.
Single point ground for the entire station. Just trying to save a few
bucks on the transmission lines.

Thanks for all the tips,

Bob

  Hmmm!  FAA doesn't paint coax cables!   However, If this hardline was attached to  and then removed from a structure located near an airport or airfield, then there would be some orange and white paint.  This paint should do no particular harm to the coax cable jacket.   

Personally, if this coax you have is RG-331 or RG-333, I'd put it on eBay and get some good coax.

Re: [Repeater-Builder] Amplifier

[Eric Lemmon]

Jimmy,

The TLD1693E is a Motorola MICOR 100 watt continuous duty power
amplifier for the 150.8-162 MHz split.  It is designed to be driven with
400 mW of RF, and an internal power control board keeps the output
stable at 100 W.

Although some of these PAs may seem to work at the high end of the 2m
band, they will not be efficient or stable.  Moreover, an unmodified
TLD1693 amp will ultimately fail if operated well outside of its design
parameters.  What you need for the Amateur 2m band is the TLD1692 model,
which is designed for the 132-150.8 MHz band.  There are about 90
different components between the 1692 and 1693 amplifiers, and it is a
major task to modify.  Although the mod can be done, it is an expensive
and time-consuming effort.  A month or so ago, a poster to this list
described his experiences in modifying TLD1693 PAs for the 2m band; it
makes interesting reading!

The part number for the Micor multi-PL manual is 6881106E30.  It does
not come up as a valid number at Motorola On Line - so it would appear
it is NLA.

If you cannot locate a copy of this document, remember that many of
the MSR2000 control modules are identical to the corresponding Micor
parts with the exception of the edge connector and panel color.  The
MSR multi-PL modules do appear to be electrically the same as the
Micor ones and unlike Micor, the option board docs were included in
the standard station control instruction manual.  The MSR manuals show
up on ebay from time to time.  The part number is 6881061E40.

Re: [Repeater-Builder] Another mystery card

[Neil McKie]

  Hmmm ... 

  Some questions on here are easily answered by either a yes or no. 
 Not with Mike however ...  

  As a result, I went out to my garage and now have the manuals on 
 the Motorola Micor Community Repeater ... 

  The Micor Manual Part Numbers are as follows: 

  RF Specific  68P81025E50 406-420; 450-470 & 470-512 MHz - 

  Control and Application  68P81025E60 

  Community Repeater (RT)  68P81025E55 

  The 'Four User Control Module' as it is labeled, in the manual I 
 have here, model number is TLN1685A.  This is used with the Micor 
 UHF C64RCB-3105AY.  

  How this differs as compared to your TLN5745A board is anybody's 
 guess: 

  The use of this board is it needs to used with the Micor Station 
 Master Decoder Module TRN6165A ... as this board supplies the 
 needed signal at the correct level for the other board.  You can 
 probably find a similar signal at the correct level on your Model 
 TRN6002A "Private-Line" Tone-Coded Squelch Decoder.  

  Remember the PL Decoder reed is expecting approximately 0.8VAC 
 peak-to-peak signal driving the primary.  The emitter of the driver 
 transistor has about 8V peak-to-peak.  

  Remember, the back plane (mother board) of the Micor Community 
 Repeater is unlike what you will find on the standard single user 
 repeater.  

  Community Repeater mother board part number: TCN1211A 
  Standard Single User mother board part numberS: 
 TCN1187A/TCN1190A/TCN1224A/TCN1225A  
   all depending on how you wish to read the manual ... 


  Tha manual I have here, 68P81025E55, has the following as pin 
 connections for the TLN1685A Tone "PL" Four-User Control Module: 

  1 NC
  2 NC
  3 "PL" Tone Input
  4 NC
  5 NC
  6 NC
  7 NC
  8 NC
  9 NC
 10 NC
 11 Detector Emitter Bias (from the Master Decoder Board, pin 11)
 12 A+ 
 13 NC
 14 NC
 15 NC
 16 NC
 17 NC
 18 Detector Base Bias (from the Master Decoder Board, pin 18)
 19 No. 1 Decoded Output 
 20 No. 2 Decoded Output 
 21 No. 3 Decoded Output 
 22 No. 4 Decoded Output 
 23 Gating Signal (Gnd if not used with a single tone decoder) 
 24 Switched Ground Output (to Master Decoder Output Switch)

This is a MICOR PA VHF 100W Continuous duty frequency range 150.8 MHz to 
162 MHz. The amp might work on 2 meters. by the Motorola manual there are 
more than 30 parts to change to get it into the correct frequency range.
