Re: [Repeater-Builder] Uniden Key

[kevin valentino]

i just had a copy cut for a tech. tell your key cutter to look again, the one i 
fought with  (a master locksmith) finally  found a standard blank staring him 
in the face on the carousel. the confusion came when i told him it was to open 
a 2-way, the "head" was a different shape.

[Repeater-Builder] Re: Building Low Band Loop Antennas (DB-212)

[wa6ifi]

I have a 2 loop DB212-2 which is cut for 48 MHz.  I want to use it for a 6M 
repeater on 53.13.  I've shortened the loops to about 53".  Do I need to 
shorten the length of the coax which runs from the antenna to the "T"?  What 
should be the length of the cable that runs from the "T" to the feedline (cable 
C in instruction flyer.

RE: [Repeater-Builder] Mtr-2000 for 2m use.

[Eric Lemmon]

Norm,

You're welcome!  You don't need to read the radio to get the necessary
information- just look for the small paper labels on the rear of the power
amplifier, and decode the numbers with the chart I mentioned.

Regarding the preselectors, I never could figure out why some folks always
specified an external preselector, even without any compelling technical
reason.  I can see using the preselector as a precaution only when several
base stations are co-located, but the standard internal preselector used in
the MTR2000 works just fine in a repeater.  I have eight MTR2000 repeaters
in service now, both commercial and Amateur, and none of them have or need
an external preselector.

Hi Eric and thanks for the input. 
I will read the repeater out here in the next day or so. That should give me
the model info. 
The reason I brought up the external preselector is that every other
MTR-2000s I have seen have the preselector bolted on to the rear of it. 
Thanks for you help!

Norm, 

None of the numbers you provided identifies the band or power of your 
MTR2000. It happens that the MTR2000 contains an internal preselector, but 
that fact is irrelevant to 2m operation- the duplexer will allow any VHF 
MTR2000 to work on 2m. All MTR2000 stations purchased through retail 
channels carry the model number T5766, regardless of band or power. 

First of all, do you know for certain that the station is VHF? If so, does 
the station have fans in the heat sinks? If so, then it is a 100-watt class 
unit. There are two models of 100 watt VHF MTR2000 stations: One will 
operate only in the band 132-154 MHz, and the other will operate only in the

band 150-174 MHz. The latter unit cannot be made or modified to work at 2m. 

To help identify your MTR2000, go to this link to get a list of modules to 
identify exactly what you have: 
 
and some additional info is here:

I recently obtained a Motorola MTR-2000. It took a lightning hit to the tone

remote board, but the repeat functions fine. Upon close inspection, it 
appears this unit was originally used as a base station before it was a 
repeater by evidence of ant rel installed. Also it does not have a 
preselector on the rear. My question is, will this thing work on 2m and will

I have to come up with a motorola preselector to use with a 600khz split?

RE: [Repeater-Builder] 50 Watt Repeater

[Eric Lemmon]

A 40-watt Motorola MTR2000 is continuous duty, and darn near bulletproof.  I
have one such repeater that is used to broadcast Amateur Radio News and
another bulletin service, and it stays key-down for almost an hour at full
power, and it barely gets warm.  I doubt that any repeater users can detect
the difference between 40 watts and 50 watts.  Remember, buying quality only
hurts once!

Well, they can do that, but it needs to be clarified whether just 
turning down the deviation is enough. Many knowledgeable engineering 
types are saying that the filtering (splatter filters, etc) are not 
adequate in this case. And I can see that they are likely right.

Re: [Repeater-Builder] 50 Watt Repeater

MTR2000, like Mike suggested.  Solid state, ~4 inches tall by 12 deep by 19
wide (3Us of rackspace).  These repeaters are tanks and can handle 100% duty
cycle and ask for more.

RE: [Repeater-Builder] Re: Early FM Repeaters (tubes and more)

[Andrew Seybold]

If I might add my 2 cents here-I have now narrow banded a number of
Mastr II receivers, all high band, using the kit from Com  Specs, it
works Great HOWEVER, the receivers all have a problem with the squelch
threshold and there is a lot of popping going on-setting the squelch
tighter does no good-the issue seems to be that the noise settings for
the Mastr II-we have tried many different fixes including adding a Mot.
Squelch, and adjusting the "hidden" magic pot-to no avail-even sitting
on the bench with no signal applied they are very noisy-and while the
sensitivity measures about the same as before, the performance is not.

A big can of worms and there seems to be a lot of people

with their interpretations. Bores me to tears to try and 
read the legalese these folks spout. 

Some key points if I may... 

The narrow band physical mod is to the receiver. The 
transmitter is not a mod, but typically a standard 
deviation and audio level adjustment. 

It is the responsibility of the License Holder to 
ensure the emissions are legal. I personally have been 
told by more than one FCC Field Agent and a former Office 
Chief... (still working at the FCC in a higher capacity) 
they are not going to get excited about properly upgraded 
equipment properly running within the limits of the 
license requirements. 

The above has proven to be the case the few times I've 
had site interactions with the FCC. I've never seen a 
Field Agent walking around with a type acceptance list 
or computer doing said look-ups.

on many groups who live to post various FCC rules along 
with their interpretations. Bores me to tears to try and 
read the legalese these folks spout. 

Some key points if I may... 

The narrow band physical mod is to the receiver. The 
transmitter is not a mod, but typically a standard 
deviation and audio level adjustment. 

It is the responsibility of the License Holder to 
ensure the emissions are legal. I personally have been 
told by more than one FCC Field Agent and a former Office 
Chief... (still working at the FCC in a higher capacity) 
they are not going to get excited about properly upgraded 
equipment properly running within the limits of the 
license requirements. 

The above has proven to be the case the few times I've 
had site interactions with the FCC. I've never seen a 
Field Agent walking around with a type acceptance list 
or computer doing said look-ups.

What's sad is how much will likely go in the dumpster instead into some 
deserving ham's hands ;c}

Actually, there is still a legal question as to whether equipment that 
was not type-accepted for narrowband originally will still be legal if 
the transmitter is narrowbanded, ie, deviation turned down. The FCC has 
yet to clarify much of anything like that.

The disappointing part of narrow banding is the text in 
the below message.  I've been able to narrow band a heck 
of a lot of repeater equipment. Surplus repeaters and 
radio equipment are a gold mine to innovative and motivated 
radio people, who are willing to do both the homework and 
technical work. 

It's a lot more expensive and sad to think a lot of 
equipment is being replaced, when other viable options 
are available.

Hi, could anyone give me some information on what the C MSG feature is for on a 
Sinadder Model CML-1.  There is an on off switch on the front panel for this 
but I don't know what it is for.

Also, if anyone has a file for this particular Sinadder I would sure appreciate

I think it is basically a Sinadder 3 but am not sure of any differences in it.

  Norm, 

  Assuming that your radio is VHF (what were the existing operating 
  frequencies?); the VHF radio comes in two bandsplits in the high power VHF 
  station. There is no way to change one bandsplit to the other. I was 
  involved with a project where incorrect frequencies were entered by someone 
  doing an order resulting in a range 1 receiver and a range two transmitter. 
  The radio ended up being sent back to the factory and replaced by an 
  entirely new unit to correct the problem. 

  The best way to proceed at this point is to have someone with the proper RSS 
  read the radio and give you a printout of the existing codeplug.

Re: [Repeater-Builder] Mtr-2000 for 2m use.

[NORM KNAPP]

Hi Eric and thanks for the input.
I will read the repeater out here in the next day or so. That should give me 
the model info.
The reason I brought up the external preselector is that every other MTR-2000s 
I have seen have the preselector bolted on to the rear of it.
Thanks for you help!

Norm,

None of the numbers you provided identifies the band or power of your
MTR2000. It happens that the MTR2000 contains an internal preselector, but
that fact is irrelevant to 2m operation- the duplexer will allow any VHF
MTR2000 to work on 2m. All MTR2000 stations purchased through retail
channels carry the model number T5766, regardless of band or power.

First of all, do you know for certain that the station is VHF? If so, does
the station have fans in the heat sinks? If so, then it is a 100-watt class
unit. There are two models of 100 watt VHF MTR2000 stations: One will
operate only in the band 132-154 MHz, and the other will operate only in the
band 150-174 MHz. The latter unit cannot be made or modified to work at 2m.

To help identify your MTR2000, go to this link to get a list of modules to
identify exactly what you have:

and some additional info is here:

The good news is that the MTR should be narrowband compliant, so I 
expect you could sell it back into LMR service.

Re: [Repeater-Builder] 50 Watt Repeater

I run a Harris Radio Phone ( converted to repeater) and it runs 60w all day
and all nite long

Join the Harris yahoo ground and send a note to Roger   he does them um in
UHF and VHF  when you order from him the radio is on you freq. and all tuned
up ready to go ...  and every thing you need is right inside the case .. COS
PTT audio in Audio out ..

the only thing you might add is the CTCSS  ( I am working on a good spot to
put it for incode but the decode again is just right inside ..

GREAT little radio and solid  its been on the air for more then 7 years now

Re: [Repeater-Builder] 50 Watt Repeater

[Doug Bade]

Icom Systems group sells a version of the FR3000 with a 100w amp and 
additional power supply, if you are looking for off the shelf.. that 
is how you get 50+ watts at 100% duty cycle... Most folks opt to go 
to less than 100% duty cycle to keep from doubling the cost... but if 
you really need 50+w all day all night all nice. you need a 
station with an amp rated at that

Probably still cheaper than buying a Harris or Motorola 100w station 
ie Mastr III or Quantar or similar ... For public Safety I would 
still look at these latter two choices.. as their 100% track record 
is readily duplicate-able.

I believe Kenwood sells a similar arrangement... The little desktop 
size repeater just do not have the heatsink and cooling to do 50W 
@100% without some form of additional external amp... It is about 
heat dissipation.. 50watts is easy.. cooling 24x7 in any reasonable 
environment is a little trickier...

While you can force anything to do 100% that does not mean it was 
engineered for it..or suggested.. :-) That engineering generally 
costs... or if it is for amateur.. Build it :-)

1970 protocol in upstate New York was to use 146.94 as a simplex
