Like most of the commercial stuff of that era,  the unit was locked into a 
car or truck instead of bolted in. It made for an easier repair to just unlock 
it rather than unbolting everything. It sat in a cradle with the locking 
mechanism that WAS bolted to the car body. GE and RCA also had their

 Hi,
 I know it's a dumb question, but after scouring the internet for info, I 
 find everything about locks and replacement keys for Motorolas and other 
 radios, but I still don't know what locking the Mitrek actually does. 
 Does it kill all power to the radio, or disable certain functions?  I'm 
 asking because I just acquired a low-band Mitrek that I need to power up 
 and verify its working condition.  It doesn't have a control head, so I 
 need to use the front panel pins, but if the radio is locked, I may end up 
 getting nowhere and still not know if it's either the radio that is bad, 
 it is locked out, or I wired it wrong.  This is the first Mitrek I've had. 
 Thanks for any help.

I had a similar experience with a low power FM transmitter that a church 
put on the air.  I started to get interference on my 6 meter repeater. 
It turned out that the local church moved their FM station to the tower 
that I am on and put their antenna on the top of the 300 foot tower 5 
feet away from my 6 meter antenna.  They never modified their license 
for the new location and were way over the height on the tower that they 
were licensed for.  The problem was that I was running an ARR preamp 
that worked fine until the FM station caused overload.  They ignored all 
that I warned them about and I ended up taking the preamp off.  (I'm a 
guest on the tower and I'm not about to complain to the owner).

Anyway, they are running more power then they are licensed for, too high 
on the tower for a low power lFM license, and never got licensed for the 
new location.  All this for spreading the word of the Lord.  They mean 
well, but seems ironic to me.

Re: [Repeater-Builder] Any Repeaters Taken Off Air Permanently?

2009-12-27 Thread Pointman
In my area there have been several repeaters taken off the air for various 
reasons. Mostly for non use. There were a few super repeaters that covered a 
wide area, but for some reason, even they don't get much use anymore. I guess 
Nextel and the like killed them. Its funny...there is a university system in 
the area, that has machines all over the state and in surrounding states as 
well, but I never hear anyone on it. None of the older local machines are in 
use. There is a Super Repeater that is single site, and has the same crew 
operating it as it did in the early 80's. It's great to hear the guys I've 
known for over 25 years still operating!!

Myself, I had an 80 watt UHF repeater than had 220, 6, and 10 meter remote 
bases. I never expected the 6 and 10 meter links to be used locally. I wanted 
to give my users the option of working a distant station on the higher bands. 
This was successful to a limited degree. But as with the gentleman before 
stated, there were few local 6 meter users, and even fewer 10 meter locals. I 
did manage to converse with the 10 meter machine in the Virgin Islands on a 
regular basis when the sunspot cycles were hot...but at the bottom, literally 
nothing on the air. Likewise 6... I had a great shot to both Florida and the 
midwest (particularly Wisconsin, for some odd reason) on a regular basis. The 
220 link was used to link to another repeater in a shore community about 70 
miles away. It worked great at both ends, but there was a lot of dead spots in 
the middle. I finally took it off that site after the owner of the building 
sold the use of the roof to a cell phone
 company for $450,000!!! Money talks and you know what walks. I have to say, it 
was a great run because I was on that roof from 1984 to 1999. The machine is 
now at my house in a small city, and is strictly UHF with he 220 link still on, 
but all of the remote gear is still in the cabinet, but not in use.

I have taken at least 3 amateur radio repeaters off the air in the last two 
years. These
repeaters where all located in a large metropolitaian area ( 3 million 
residents).
 
2 meters - This was a repeater used for user access to a multi-state repeater 
linking
system.  - Reason -  No support from the local amateur community and I lost the 
main
repeater site due to a sale of the property where the tower was located.  I ran 
this 
repeater system for 4 years. Its frequency was re-issued for other uses within 
a few 
months after I shut it down.
 
6 meters - No users on 6 meters in the area. I operated this repeater on and 
off for
about 10 years.  Lots to 6 meter repeater pairs available in the area.
 
10 meters - Repeater was not serving the local radio community. 10 meter FM 
ground
wave coverage was poor, so no local support.  This repeater was mainly used by 
amateur radio operators located in an area in about 1200 mile radius around the 
repeater
transmitter.  It gave good coverage to the US east coast ( from the center of 
the US).  The
only 10 meter repeater that gave good coverage here was located in the Virgin 
Islands.
I opereated this repeater for about 15 years ( thru multiple sun-spot cycles). 
Another
repeater is now being just established on the vacated frequency pair in the 
area.

Ralph you bring up a good point of thought.

The ham that built our repeater placed the Decibel Products 4002 Bandpass 
behind the Wacom 6 can duplexer and then followed by the ARR Gasfed 
P144VDG to the radio.

Now where he built it was his tower site (an old ATT brick building) full 
of transmitters.

Now that we have it, it is located here at my house in my ham shack. So, 
the only transmitters are my 2 meter and HF when I am on HF. The HF 
doesn't bother it at all and I run low power on 2 meter when I am on that.

So, with your thought, I could probably do away with the bandpass all 
together run the preamp right out of the cans to the radio (which is a GE 
Mastr II mobile).

Yes, but it will offer some protection from your 2 meter radio so you'll 
desense your repeater a bit less.  It also offers some protection from the 
EMP of nearby lightning strikes: less bandwidth between the strike  preamp 
means less EMP energy reaching the preamp's input.

The DB4002 came with either 0.5, 1 or 3 dB loops.  If yours has 3 dB loops, 
then you'll probably see some improvement in sensitivity by removing the 
can.  If it has 0.5 dB loops, you won't notice a difference.  1 dB is 
somewhere in between, but if you have any amount of site noise you probably 
won't notice a difference as well.

Here in SoCal you can put a 6 dB pad in front of a preamp  not notice a 
difference in effective sensitivity.  Needless to say, I don't use them on 
2 meters here - the stock sensitivity of an MVP or Mastr II is perfectly 
matched to our environment.  I have noticed that away from this area, the 
noise floor on 2 meters can be much lower.

A total insertion loss of about 1.0 dB works well, in my experience.  With
two 8 bandpass cavities in series, this gives at least 25 dB of isolation
from the transmitter carrier at a 600 kHz split.

Bear in mind that your notch cavity has the same deficiency as the typical
BpBr duplexer-  there is relatively little bandpass effect.  A pass-notch
cavity is a poor substitute for a bandpass cavity.

So what is the recommendation to set the loss of the BP cavity? I have a
setting as to 3 dB, 1 dB, .5 dB etc. Running the ARR preamp on a UHF
repeater, it seems the preamp is a little too much and we get a little
desense. I am only running a 4 cavity duplexer and a notch cavity with the
preamp.

Re: [Repeater-Builder] Linking Repeaters Remotely

Make sure you Full PL BOTH tx and rxers. I have had great luck with this 
method. At least with the Motorolas I use as soon as the input signal is 
dropped, the no squelch tall...and therefore no constant keying.

 There have been times when during events it would have been great if two 
 different repeaters had been linked. I've been kicking around the idea of a 
 portable repeater linker consisting of one VHF Radius, one UHF Radius, and a 
 RICK controller in the crossband mode. I've talked to the different repeater 
 owners and they have given me permission to give my idea a try.

 

 The 'linker' works great the first time. The receiver radio hears the output 
 of the first repeater and keys the transmitter radio which keys up the 
 repeater. The problem comes in when the transmitter unkeys. The receiver 
 radio hears the tail of the second repeater and keys up. When the second 
 machine drops, the transmitter radio hears the tail of it's repeater and keys 
 up. This continues FOREVER. 

 

 Does anyone have any ideas or additional logic I can add to solve this 
 problem?

 

 Thanks,

Kinda.



First... the idea Matthew offered will work.  CTCSS on user signal received on 
both repeaters.  Kinda.



Problem: ID's.  The RICK isn't properly ID'ing the link transmitters.



Many of us have been down this path on the list.  It'll lead to an annoying 
discussion of Part 97 if we go too far down that road.  But you DO need to ID 
every transmitter.  'Nuff said.



Best way: Put a dedicated link TX/RX at each repeater site or some sort of VoIP 
linking on its own controller port.  In-band RF linking on the user input 
frequencies is a kludge at best.  It can double with users, and has other 
timing problems...



If you MUST link in-band, make the link margin (RF power) high enough that if 
the link doubles with someone, the LINK wins and captures the repeater receiver 
well enough that at least one of the transmissions can be heard by all...

Hello Bob, Well..I know you would know what a good machine
should sound like.  You have worked a few I know!  Steve, W4YHD had done some
audio tailoring within the unit but just what I could not say.  But I know it 
has
been on the air with nary a glitch for a quarter century or more.  In fact I
would say that his repeater has been the most reliable machine in our club all
the years I lived up there.  And it is still going strong.  - Mike

Wondering what you did to it to make it sound so good. Every one I've

can usually tell if a repeater is a Kendecom by the characteristically poor

  I wound up with a set of Tx/RX 28-38-03-C vari-notch duplex 
today. I was not expecting much. I got them cheap. The cans are only 4. No big 
deal. Bigger cans = deeper notches with less insertion loss, right? Well, 
unless my site master and IFR-2945B are lying to me, I got -100db on the 
notches and 1.2 db insertion loss! I will say this, the coupling loops are very 
different than what I have seen in sinclair, telewave and db cans. Does anyone 
else have any experience with this model? Am I reading things right?

All I got to say is, incredible!

There's a discussion on the list about how HF Remote Base stations are most 
likely not legal. Trying to reason with some of these people is an excercise in 
futility. But if that was the case, why do almost all new higher-end Repeater 
Controllers (and even some of the older 1980's controllers like the ACC RC-85 
and SM-100 ShackMaster , AEA Radio Link unit, etc.) have direct control of 
various HF transceivers' capability? 
Here' s one of the responses: 
Is it legal to have a remote base with an output on HF below 29.5 MHz? 
No. If you look at the rules regarding the frequencies available for auxiliary 
operation, you will conclude that there is no such thing as a legal remote 
base which uses frequencies anywhere in the 2-meter band for the uplink and 
downlink. Those systems that go from 2-meter FM to 10-meter FM, or from 
2-meter FM to 6-meter FM, for example, are not technically remote bases, even 
though some hams like to call them that. They are really crossband repeaters 
and they are legal only if both ends are within authorized repeater segments of 
both bands. Repeater operation (including all input and output frequencies) is 
prohibited on all HF amateur bands, except the top end of 10 meters. Likewise, 
there is no such thing as a legal 2-meter FM to 75-meter SSB remote base, 
since auxiliary uplinks and downlinks must all be above 222.15 MHz [97.201(b)].

  I pulled off linking two adjacent 224MHz Repeaters. 



The repeaters are on different 30 mile distant mountain 

top sites. 



One repeater has an on-band linking radio (Alinco DR-235) 

set up on the adjacent frequency. As an example... 224.960 

and 224.940MHz.  



With enough physical isolation, filtering and setup... 

much to my surprise it works pretty well. The owner wants 

to now park IRLP on it and waste everyone's time. But they 

are his repeaters... 



On toward part 2.
