[Repeater-Builder] Swap my CAT300 for your Zetron 38A

[dave_g7uzn]

There may be some that think that I have lost my mind! but I would like 
to swap my working CAT300 with copy of manual for a working Zetron 38A.

I will pay postage to you and you pay postage to London UK. Strictly 
replies direct and first come first served.

   Any takers?  Cheers Dave UZN

[Repeater-Builder] Re: CAT300 programming?

[dave_g7uzn]

WRONG!If the repeater isn't used until next month, then the 
beacon won't be sent till next month!

[Repeater-Builder] Schlumberger 4031 mod B module required please

[dave_g7uzn]

Hi All, I have inherited a 4031 but it doesn't have the mod B gen 
option fitted. Has anyone got a spare module or a blown up 4031 with 
the module in please?

I appreciate you can use the Ext Mod input but it's becoming a bit of a 
pain in the grass!

[Repeater-Builder] CAT300 programming?

[dave_g7uzn]

Hi All, I have a cat300 controller (not DX) and am wading my way 
through the manual. The problem is that in the UK a repeater MUST send 
out it's ident every 15 minuets and as far as I can see although the id 
timer can be set for 15 mins, it will only send it out when the 
repeater is bought up! Is there a timer or other way of forcing the 
controller to give it's ident even if it has been idle?

[Repeater-Builder] CSI 3850 problem? (second call)

Hi All, I have a CSI 3850 controller that is being naughty! The problem

to 37 (factory reset) and left the back-up battery dissconnected but
the problem persists any ideas lads?

[Repeater-Builder] MSF5000 help please?

[dave_g7uzn]

Hi All, Let me first of all say that I don't know if the 5000 I have 
is working or faulty! It is not complete as I only have the control 
tray and the vco/rf tray (no psu or pa).

It's a uhf CXB secure capable version.

This is what I have done in an attempt to read the code 
plugConnected 12v dc to the relevent wires on the 9 way sil 
socket and 5v dc at the relevent wires. The 6 way molex is 
unconnected as is the 40 way ribbon connector to the remote board.

When I switch on the psuNothing
When I put the toggle switch to 'reset' the led display says 8.8.8.
the secure fail led illuminates, as does the leds on the remote unit 
fail,line ptt,fail soft,trc encode.
I have changed some of the jumpers to tell the unit that there isn't 
a secure board fitted but it didn't make any difference (I have 
restored them to their original position)

Can anyone point me in the right direction to get the alarms out so I 
can read the code plug please (that exercise failed as well!)

Thanks in advanceCheers Dave UZN

 

[Repeater-Builder] Re: Motorola MSF 5000 power connections?

Thanks for the responce MarkI share your concerns about having 
everything connected/terminated. I have trawled through all the files 
I can find and whilst some manuals show the interconnections as 
lines, none go to core level (unless I've missed them)

The chances of finding the missing componants are slim to say the

as follows

9 way power sil socket ...red,white,brown,black,blue,orange,green

6 way plug to pa metering...green,black,white,red,brown,orange

40 way ribbon to remote control

I don't have a manual so don't know where to shove some dc to check the

[Repeater-Builder] Re: Motorola MSF5000 s/w required?

[dave_g7uzn]

Why would they come knocking on MY door...surely they would knock on 
the persons door that sent it?

This is the main reason why Motorola are largely avoided in the UK 
due to the 'closed door' attitude. I would bet that I would have a 
real problem finding an authorised dealer willing or now able to 
program a 5000 for me. I wonder how many Motorola repeaters 
throughout the world have had their proms 'tickled' by borrowed s/w?

Hi All, I have a CSI-32 tone panel that will work at 120 volts ac or 12 
volts dc. We in the UK only have 240 volts ac and having had a look at

[Repeater-Builder] 6M cans (the next stage)

Well I seem to have inspired some healthy disscusion about the black

I know the next question is going to be like asking "What is the best

e.g. Waycom, Phelps Dodge, DB Products, Celwave, Sinclair etc

Suggestions lads?

[Repeater-Builder] Re: 6M cans made from other metals

[dave_g7uzn]

Hi Steve, I would be very happy to empty the beer barrels of there 
contents! Seriously though there is a company in the UK that make 
filters out of barrels but they only work down to about 68MHz due to 
the lengh. I have a set and they would make an excellent 70MHz duplexer 
but we don't have 4M repeaters here!
As far as oxygen cylinders go.I'm not sure what they are made of 
but I know the carbon dioxide ones used in fire extinguisher systems 
are made from cast iron and are lined with concrete.

[Repeater-Builder] Re: 6M cans still wanted in UK

[dave_g7uzn]

Thanks for the suggestion Erik but 2 site working isn't really an 
option as there is only one tower in the area that I have access to. 
Come to think of it I don't think there's even a tall building nearby.

I would like to try and use single aerial working so there is a good 
balance between tx and rx paths.

   Cheers Dave UZN

Thanks for the link Chuck...I have seen it before but the irrigation 
pipe is plastic in the UK! and to buy the raw materials new would 
cost more than a second hand set INCLUDING shipping.

Come on lads there MUST be someone with a set of 6M cans willing to 
send them to London? I had a word with Santa but his sleigh is full!
   Have a great ChristmasCheers Dave UZN

[Repeater-Builder] Re: 6M duplexer wanted in UK

[dave_g7uzn]

Hi Ian, All points noted and I do appreciate that a few 6M repeaters 
in the UK do use the heliax design but I do wonder how stable and 
efficient they are compared with a set of 4 Wacoms or similar. I 
must admit that I have 8 suitable lenghs of LDF750 that has been 
donated by our understanding aerial riggers but have not yet got a 
soldering iron to them! I do however intend to make one stub and see 
how that looks on a spectrum anyliserI suppose in this weather I 
could leave it out in the cold for a couple of hours and test it and 
let it warm back up and test it again to see it's stability.

Having spoke to those that have got proper cans on their repeaters 
they all recommend going down the can route (despite the expence)

  Cheers Dave UZN
ps.Still looking for someone with a set of cans for sale.

[Repeater-Builder] 6M cans still wanted in the UK

[dave_g7uzn]

Hi All, I rescently posted that I need a set of 6M cans for a repeater 
project in the UK. Despite one offer that appears to have fizzled out. 
Is anyone prepared to sell me some high quality cans and ship them to 
the UK? All expences paid.

  Thanks in advance..Cheers Dave UZN

[Repeater-Builder] Re: 6M duplexer wanted in UK

[dave_g7uzn]

Are you saying that a duplexer built from heliax can cope with a 
0.5MHz plit at any temperature?I somehow doubt it (no invar!)

Cheers Dave UZN

[Repeater-Builder] 6M duplexer wanted in UK

[dave_g7uzn]

Hi All, Is anyone with a set of cavity filters suitable for 50/51MHz 
brave enough to sell them to me and get them shipped to the UK for a 
6M repeater project? ALL expences will of course be covered. If you 
can help please email me direct at

[EMAIL PROTECTED]

Thanks Dave UZN

[Repeater-Builder] 6M cans required

[dave_g7uzn]

Hi All, Does anyone have some cavity filters suitable for 50/51MHz. 
They must be reasonably priced as postage to the UK will be high.

Please email me direct if you can help.Cheers Dave UZN

[Repeater-Builder] CSI 3850 controller problem

[dave_g7uzn]

Hi All, I rescently purchased a CSI 3850 shared repeater panel but 
when I came to program itIn A_U_ section parameters 
1.9 = 
2.0 = 38.49
2.3 to 4.1 all = A !!

I performed a factory reset but this hasn't cured the situation then I 
disconnected the backup battery for 5 mins and that didn't help either.

The eprom has a blue sticker on it and there is a date stamp on the 
unit pp #3  11/89

Can anyone tell me if I need an upgrade or is the unit knackered?

Ant help much appreciated..Cheers Dave G7UZN London

[Repeater-Builder] Disable dtmf on Zetron 38A?

[dave_g7uzn]

Hi All, It has been pointed out to me that one of the disadvantages 
of using a Zetron 38A as a repeater controller is that the "back 
door" dtmf method to set the device to default settings is widely 
available on Net! Is there any way of disabling dtmf programming once 
the perameters have been set, even if a pin on the dtmf decode chip 
need clipping or bending out of it's socket?? Any suggestions 
would be much appreciated...Cheers Dave G7UZN

Does this type of eprom require a special adaptor, if so what is it

[Repeater-Builder] 6M cavity filter design ?

[dave_g7uzn]

Hi All, You will be pleased to hear that I have scrapped the idea of 
using carbon dioxide bottles for the 6M cavities and have instead 
been put in touch with a local ham that used to own an engineering 
workshop who is willing to help by supplying 6" or 8" ali tubing.

The problem is that I can't find any designs for the filters to work 
on 50/51MHz .i.e. tube lengh, loop lengh etc. Can anyone please 
point me in the right direction to a Web site or supply any 
design/dimensions please ?

  Any help appreciated.Cheers Dave G7UZN London

[Repeater-Builder] 6M duplexers using C02 bottles ?

Hi All, and greetings from the UK.

Has anyone ever considered using 8.5" diameter 6ft high carbon

filters ?

I know it may seem as a bit of a crazy idea but we have loads of them 
surplus at work! Any thoughts/designs would be much appreciated.
