RE: [Repeater-Builder] Identify Please

Hi Eric, 

The steel cases are not an impediment to the magnetic field, at least not 
enough to make retuning impossible. Microwave type circulators are built in a 
similar fashion, just smaller, and the technique is well known among those of 
us who play in the microwave region. Just to give an idea of the magnitude of 
change that's possible, 1.8 GHz circulators can be moved up to 2304, and I have 
moved 11.7 GHz circulators down to 10368 MHz. 

I haven't specifically attempted to move 870 MHz circulators up to 928, but I 
see no reason why this couldn't at least be attempted if someone was so 
inclined. 

If someone wants to attempt it, you can either dissect an unwanted circulator, 
or maybe better yet, use some of those extremely powerful rare earth magnets. I 
buy 'em by the handful at the county fairs for cheap, just to have them around 
for such purpose. 

The network analyzer makes it seem stupidly simple, but a SA/TG would work 
nearly as well. Just remember to check it both ways before you apply the glue.

RE: [Repeater-Builder] Identify Please

[Eric Lemmon]

Mel,

I have heard that done, and if it works, great.  However, the
remanufacturing of typical VHF and UHF circulators almost always involves
machining or replacement of the ferrite components.  Since the Celwave
circulators that started this thread have steel cases, I wonder how an
external magnet can affect the internal magnetic field.  I certainly agree
that a network analyzer is best suited for circulator tuning.

A lot of us amateur microwavers retune circulators with external magnets.
With a handful of otherwise useless circulators, one could tear one apart,
recover the magnets, and apply them to the outside of the case of the unit
to be tuned. 

A network analyzer helps, so you can watch what's happening in both
directions, but that's not a requirement. You can tune them up or down quite
a bit, depending on the orientation of the external magnets. Once you find a
combination that works, the external magnets get glued to the circulator
case with epoxy.

John,

Don't get your hopes too high, because most dual isolators can only be tuned
3% or so away from the frequency they were manufactured to operate at. For
example, my Celwave catalog shows those isolators for the 806-1000 MHz
range, but that range refers to the manufacturing capability and not the
tunable range. In fact, most manufacturers of circulators and isolators
will advise you that the unit must be remanufactured if the operating
frequency is moved more than a relatively small amount. A case in point:
One local radio club received a dual isolator that was originally made for
the 152 MHz commercial band, and wanted to use it on a 147 MHz Amateur
repeater. Although it SEEMED to tune down that far, it actually began to
generate some spurious signals and got quite warm. It was shipped back to
the manufacturer for reworking, at a cost of about $250, and performed
perfectly afterwards.

Since your isolators are made for 875 MHz, you might get them up to 902 MHz,
but probably not much further. YMMV...

Re: [Repeater-Builder] Identify Please

[DCFluX]

I might be a little wrong because I dont have one in front of me, but try
this:

Connect the Generator of a spectrum analyzer to the connector all the way to
the right.

Connect a dummy load to the connector on the bottom left.

Connect the detector to the connector all the way to the left.

You should see a dip where the port is currently tuned.

Try moving the adjustment screw next to the port with the dummy load on it.
Outwards should increse the frequency.

Note how far up it will come.

Then "Rotate" the connectors so that dummy load is all the way left,
detector all the way right and generator bottom left. Tune next capacitor
and repeat.

Then you can do basically the same for the next stage.

I just walked over to the shelf and grabbed 2 or 3 of the identical Dual 
Isolators.  I think these came out of Cell Sites.  That would make them 800 Mhz.

 

I can add to your land fill exercise John!

Thanks all for the speedy responses. I found one more (with a tag to boot!) 
assuming they are all the same, they are Model CD800-F, tuned to 875.00 MHz. 
Ugh, more 800 crap for the junkpile! Is it wrong to be cursing Nextel? I will 
probably be sweeping it with a generator and make sure these are all the same. 
With the tag, it should be cake.

Looks like a two stage circulator. One port is for input one for output and the 
other two (that come out the same side) are terminated into 50 ohm dummy loads.

Unknown what frequency range, probably 800-900 range, just guessing.

Ran across a box of 5 or 6 of these units. Have no idea what they are aside 
from being a CelWave R.F product. If any of you have one of these, maybe you 
can tell me what it is, and what bandwidth it would be for. Right now, its my 
*guess* that its an 800 band contraption.

 

Thanks for your insight!

They may stretch up to 902-928 Ham.

I should have said a dual stage circulator...

Re: [Repeater-Builder] Identify Please

It is a dual stage circulator.

Attach dummy loads to the bottom connectors and sweep it with the generator
on the antenna side and the detector on the transmit side, you should see
about a 40-60dB dip on the frequency it is tuned for.

RE: [Repeater-Builder] GE 1000 Key

Assuming they are kind of a two tone beige GE Master II cabinet, you will
require a GE1000 key.

 

Any local two way shop would have several in desk drawers.  It would be
faster and cheaper than mailing one to you.  A locksmith that has been in
the business for many years might even have one in his bin of keys.

[Repeater-Builder] Re: HAM Mototrbo Systems

[zigs68]

Hi - 

I read in a post you made in late March on the hamtrbo.org forum about trying 
out the Hytera (HYT) equipment on a mototrbo system you had up and running to 
see how it worked and how compatible it was.  Also you mentioned an outlet for 
hams to purchase.  Of the HYT dealers I have seen and places offering HYT 
equipment no one is offering the equipment yet - to be fair the product 
announcement was only last month so these things do take time I guess.

Any word on how things are working with the equipment on your system if you 
managed to get that far yet?
