  Those are of no use for 2 meter ham, being as they are for a 5 MHz split.
  However, it might be possible to use them on the 440 band.

[Repeater-Builder] ID-O-Matic Installation on Mastr II Stock Repeater Card

2008-05-25 Thread Jim Brown
for: Mike Morris WA6ILQ

Mike, I just uploaded my files on a simple installation of the ID-O-Matic on a 
Mastr II repeater audio board.  They are found in the Mastr II group files.

If you are interested, you are welcome to post these files on the 
Repeater-Builder site.  I don't have a way to consolidate these files into a 
single .PDF, so you can edit them into a single file if you so desire.

The install adds a CW ID and a squelch tail with courtesy tone to the existing 
GE repeater audio and repeater control cards.  No addition is required to the 
control card, the whole thing installs on the repeater audio card.

VHF HB mobile duplexers can't be tuned to 440, but if it's a 6-section

[Repeater-Builder] GE Mastr II Station battery backup question

2008-05-25 Thread Willis M. Hagler
Hello All,

I have acquired a UHF Mastr II station in great working order.   It's
got what appears to be a 65-watt mobile type PA (approx 2 high
heatsink that sticks out the back) so someday I'd like to upgrade that
to a continuous duty model when I run across one.

In the mean time I am wondering how to adapt a battery backup system
into this unit.   I've got the original 30 amp (I think) GE power
supply, where the station gets power from the classic Molex-style
connector and the PA gets power through the large fuse on the rear of
the unit.

What I don't see anywhere back there is any designated place to hook
up a battery circuit.

I'm pretty sure there are hundreds of these things across the country
in amateur service and undoubtedly many of you have made some battery
system for this very same setup.  If anybody could share how you've
worked in a battery backup and some sort of charging system I'd love
to hear about it.

Thanks all!!

Re: [Repeater-Builder] GE Mastr II Station battery backup question

2008-05-25 Thread Jim Brown
Willis, I have run across two different versions of a factory mod to apply a 
backup battery to a Mastr II.  One has a built in charger and the other uses an 
external charger.

The stock GE power supply has a bleeder resistor across the output to keep the 
voltage in check when lightly loaded, and that has to be disconnected in 
battery service.  The relay in the power supply changes the source over to the 
battery when the AC power fails and disconnect the bleeder at the same time.  
It would quickly discharge the battery if it were left connected.

The filter caps are still in the circuit when the battery is engaged, so there 
will be no interruption of service when the AC fails.  Not even a glitch on the 
transmitter if it happened to be keyed.

Here is a link to a recent backup system I installed on a GE Mastr II repeater. 
 It did not have the built in charger, so an outboard charger is used.

I had installed some EGE lowband bases some years back, now 11 years, that had 
battery back up and they had a separate, I think 10A power supply that charged 
the battery and I believe had a relay that caused the battery to connect to the 
base station on a power failure.  I know that there was a heavy interconnect 
cable assembley between the two supplies and a separate connection for the 
battery.

If you need I can try to find the #'s that were used with this system.

Hello Jim

Thank you for the information.   If my GE power supply had the
modification installed with a relay to switch to battery power then I
would assume there would be some sort of battery terminals on the
power supply.  Mine doesn't have anything that looks like that so I'm
guessing the power supply I have was not built with that mod.

Do you (or anybody else) know if it's possible to modify the power
supply to add these parts or if anything like this has been done before?

Also I am considering not using the GE power supply at all and using a
newer one with battery service built in.  This is assuming that the GE
Master II will run fine off of a regular 13.8v power supply rated for
sufficient continuous duty current.  If anybody has experience along
these lines I'd be interested in hearing about what you've done for
power supply that isn't the original GE one.

Thanks all, this is a great group of people and I enjoy reading this list!

Re: [Repeater-Builder] Re: GE Mastr II Station battery backup question

2008-05-25 Thread Jim Brown
For the GE units I have seen, the battery leads came out the large hole in the 
back of the supply where the DC leads to the fuse mounted on the rear panel 
emerge.  The Repeater-Builder site has the battery backup mod documentation and 
I downloaded it there.  I can look it up if you can't find it.

We had a lead inside a GE supply come loose after we hauled it across the 
country in a pickup, and ran the repeater off a 20 amp Astron with no problem.  
It was a 30 watt UHF unit, so the current draw was not too high.  One of the 
larger Astron supplies should run the high power units OK.  We repaired the GE 
supply and it is still in service.

There is a Molex plug on the back of the supply, and you have to connect your 
supply to both the wires in the plug and the two leads to the final amp.  The 
GE supply has a little extra filtering on the low current output and provides a 
low value fuse in that line.  You would be wise to provide a 5 amp fuse in line 
with the low current Molex connector going into the receiver and exciter area 
when using a non-GE supply.

If the repeater is located in an area where there are people, the buzz from the 
ferro-resonant transformer will become annoying after a while.  And the 
effeciency of the GE supply is not as good as an Astron.  But don't go for a 
switching supply if you can help it.  They are prone to have more problems when 
operated 24/7 in repeater service.

  Here is a link to a recent backup system I installed on a GE Mastr
 II repeater.  It did not have the built in charger, so an outboard
 charger is used.

 Hello All,
   
   I have acquired a UHF Mastr II station in great working order.   It's
   got what appears to be a 65-watt mobile type PA (approx 2 high
   heatsink that sticks out the back) so someday I'd like to upgrade that
   to a continuous duty model when I run across one.
   
   In the mean time I am wondering how to adapt a battery backup system
   into this unit.   I've got the original 30 amp (I think) GE power
   supply, where the station gets power from the classic Molex-style
   connector and the PA gets power through the large fuse on the rear of
   the unit.
   
   What I don't see anywhere back there is any designated place to hook
   up a battery circuit.
   
   I'm pretty sure there are hundreds of these things across the country
   in amateur service and undoubtedly many of you have made some battery
   system for this very same setup.  If anybody could share how you've
   worked in a battery backup and some sort of charging system I'd love
   to hear about it.
   
   Thanks all!!
