[Repeater-Builder] Re: mastrII help

[ac0y5]

Loren, I have a repeater built out of a VHF MASTRII moble running a 
NHRC2 controller. First, your repeat audio should come from the 
Volume/squelch High next, if your repeat audio is not high enough 
crank up the Rx input gain. I suggest setting the master level out 
pot on the controller to mid point and then adjust the remainder if 
the controlls to the desired level. I prefer to adjust the receive 
level for 4Khz deviation in, you get 4Khz out. That way if you ever 
need to make small adjustments you can use the master gain control. 
as far as CAS or RUS I prefer CAS, but choose which ever you prefer. 
I modified the CAS detector so it would not draw excessive current 
from the circuit. Sence I built my NHRC2 controller using sockets 
for all chips including the opto it was easy. CAS and RUS are active 
high (CAS/RUS output is about 9 volts unsquelched) I used a resistor 
in the input pin on the opto tied to a NPN transistor Base. The 
emitter and collector are pluged into the emitter and collector 
socket pins of the opto socket. 
I used Molex conectors for all connections internally to the systems 
board and I found conectors for the Power input. I used no part of 
the cable harness. If you would like to try this, get a 
squelch/Volume board from NHRC.
If you have tried what I sugested above, have you tried turning up 
the deviation level on the exciter board using the pot? Use a 
deviation measuring device to set your output.
73 and good luck and let me know how it goes

Re: [Repeater-Builder] Re: Heatsink anyone?

[Virden Clark Beckman]

If you are the lucky winner - look carefully at the solder joints on the
second output transistor from the left, also the output to the low pass
filter - there may be nothing wrong with the parts other than they have
heat cycled so many times some contacts may no longer be making any
contact. reflow the solder joints and lift away any swarf with a q-tip -
retest and put lipstick or crayon markings on the finals and watch for
it to melt - anything that doesn't melt, remove all power and signal
wiring and reflow those joints. This pa deck may be in good working
condition but has weak solder joints, it would be a good idea to switch
the regulator transistor with a to3 case component to take away repeater
duty heat and add a round heat sink to the little transistor in the
driver section. Good Luck

Sean,   All you have to do is replace the PA boards.  Take the cast shield off the low pass filter.  That gives you better access.  Some people replace the medal strip between the PA & filter board with solder wick.  Put a small hump in it to allow for heat expansion.   Fred KF4QZN    - Original Message - From: Sean KE6MOW Sent: Saturday, December 13, 2003 10:08 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] GE Z Matcher  umm...

Re: [Repeater-Builder] GE Z Matcher

[Lee Williams]

I assume you will be changing both boards as the driver is different.
You will probably have to retune the filter. Use the method in the
manual,tune for minimum SWR. Also,the pass transistor from the mobile
is probably a small tab type and the base amp is probably a TO-3,so
you will have to rewire this. Otherwise its straight forward.

Re: [Repeater-Builder] Re: mastrII help

[Fred Flowers]

Coy,   I use a different point to take audio from the receiver.  I use P904 pin 16 RX PA.  Look at the schematic for the IF & Audio board.  On the Audio IC U604 pin 6 one will see RX PA out.  This is used in the station intercom option.  C635 is used to couple the audio to the Audio PA.  You can remove that cap and not have to put a load on the speaker output.  If you want RX test audio put a switch in series with the cap.  Also notice that this point is after the volume control, Channel Guard filter & De-emphasis filter.  Use the NHRC vol-sq board to set your level to the controller.  One should have all one needs for RX audio.  Make sure your controller does NOT have de-emphasis enabled.   This method will give you control over the RX audio out & the radio will have the nice "GE" sound.  - Original Message - From: ac0y5 Sent: Saturday, December 13, 2003 2:26 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: mastrII help  Loren, I have a repeater built out of a VHF MASTRII mobile running a NHRC2 controller.

Re: [Repeater-Builder] Re: Looking for a 2 meter cavity Duplexer.

[Matt Krick]

I was hoping to make a 220 version but I dont see why it wont work for every 
band just have to increase the number of cavitys to get the isolation up there. 
the copper jacket needs to change lengths though. 

Off the top of my head:
6M = 68"
2M = 22"
220 = 15"
440 = 8"
900 = 5"
1.2 = not practical but most likely 3"

For number of cavitys, I'd say 6 for 440 and 220, 6 to 8 for 2M and 8 to 10 for 
6M. The dimensions I am using are basicly the same as a piece of Andrew 1 1/4 
heliax (LDF6-50). Because 1 1/4 pipe was the thickest I could find localy, and 
1/2" rod should be easy to come by.

Another thing, In a duplexer only the rod that moves the plunger is invar, and 
the plunger its self is still copper. So maybe copper doesnt drift that bad on 
its own?

I am considering using 1/2" brass all thread if I cant get invar, but I dont 
know how bad it shifts from tempretures, hopefully better than copper. What is 
scary is that when using all theread one cavity that is 22" long will 
contiunously tune from lower 2M to upper 440, but the rod would be hanging out 
so it would be unpractical.

For the loop, just cut a 1/4" piece of pipe and flatten it. as plate copper is 
almost imposible to find anymore. 

The ends for the pipe are like $6 bucks, which kind sucks, but the top one will 
have a hole cut dead center and a 1/2" grade 8 nut inserted. This nut should be 
"Milled" round at the bottom so that it can fit into the hole (most likely 
9/16") and silver soldered to the top cap. Once the rod is in the assembly, a 
Grade 8 jam nut will keep the rod it place. And another nut will be soldered to 
the top of the rod so the tunning tools can grip it, or a slot can be cut for a 
straight screwdriver, but I think using a wrecnh would be more precise.

Jeff,  With any O/V circuit all you need to do 
is lift off the lead that goes to the + output
and insert a 12 volt lamp between that point and 
the + output.
 
Now get yourself a variable power supply and 
connect it to the sense lead to the O/V module.
You must not connect the sense lead to the existing 
P/S at this point
 
Increase the voltage to the module until the lamp 
lights and you're done !   measure the "trip" voltage
and make what ever adjustments that you think are 
necessary.

in there also for the time out timer... and set it a few minutes longer than
what your controller is set to. in case of hardware failur on the controller
you tx and other equipment would still be a bit protected ...Good Luck,,

Pin# 18 tx audio from controller.
Pin# 8 rx audio to controller.
Pin # 6 Ground / Return

Pin# 19 and or with pin# 14 for the PTT from controller

Pin# 12 for COR
Pin# 5 is  RAW audio unswuelch ( can be used in place or Pin#8 but will
give a bit of squelch crash..)))

Pin#22 if u r using and external tone board inject the tx tone to this point
pin#22 and for the rx tone to the board use Pin# 11.
These points of connection are from  the level adj card.. column "A" facing
the rear of the repeaters mother board and are numbered from the bottom(#1)

Re: [Repeater-Builder] Tune up sheet for Celwave Duplexer 497-1

[Eric Lemmon]

Jim,

That duplexer is made in two versions.  The 497-1-1 covers 136-150 MHz,
and the 497-1-2 covers 150-174 MHz.  Since the physical dimensions and
weights are identical, I suspect that the coupling loop assemblies are
different.  The -2 duplexer will not function satisfactorily in the
144-148 MHz band, so tuning the duplexer is of no help until the
coupling loops are changed out.

Contact RFS/Celwave Tech Support at
[EMAIL PROTECTED] or 800-659-1880.  The tech
will gladly e-mail you the tuning instructions, and can advise you of
the part numbers and prices of the items you need to convert your
duplexer to operate on 2m.

RE: [Repeater-Builder] Heatsink anyone?

[Glenn Little WB4UIV]

I have a 800 MHz heat sink that I am trying to install a VHF amp on. There 
are no holes that match up. The drilling is completely different and it 
requires milling out an area where the matching network goes. The 800 MHz 
heatsink is not what you want.
