 That was way before the club bought the new (then) Motorola Micor 
 repeater. 
   73,  Neil McKie - WA6KLA 


The Palasades Club's new Micor repater on Hollwood Hills, the one I 
helped to build. I still remember that project, the late Walt 
Bronstien was just learning to spell R A D I O !! Tick was there, as 
well as the Master, Neil.
I learned from some of the great masters how to build good repeaters.

Re: [Repeater-Builder] Dual Band Handie Talkie

[KD5SFA]

The AT-600 was programable in the 2m/440 range as well as commercial and gmrs 
bands.
It could be opened up well beyond that...of course then type acceptance 
probably goes outthe window.
The HTX-204 was based on the AT-600 but only has a subset of the menu 
functionality that the AT-600 has.
The case is similar and batteries are interchangable although the differences 
in the case make the batteries
look mismatched.

The HTX-204 also could be opened way up and that is why it was pulled from sale 
a couple of weeks after it hit the shelves.

You can probably find wither on ebay.

I use one here David, the Yaesu FTH-2070. Built like a
tank, but not small compared to todays smaller rigs.

There *were* two versions available. The early ones went
from 150-174 and 450-470, and the units like mine went from
136-174 and 420-470.

They had 32 channels which were not limited to so many
VHF and UHF, so you could have 20 UHF and 10 VHF if you
like.

I think Ebay will be the only place you will find one.

[Repeater-Builder] Repeater Enclosure

[Scott]

Hello All

I've got a job here that amoung other things amounts to putting a 2 meter
repeater and associated support stuff in a weather tite enclosure the base
of a small tower. The enlosure needs to be an industrial strength and
appearing affare big enough to support 2 or maybe a bit more feet of rack
mounted gear, one and maybe two 6 can duplexers ( maybe a second repeater
some day) and all the other stuff that will and may be needed. I have about
5 feet of available width to work inside of.

Got any good ideas for me ?

Thanks much and 73,

Scott, N6NXI

Re: [Repeater-Builder] Repeater Enclosure

[DCFluX]

Hang around the local electrical company and steal a dual wide
distribution panel enclosure, the type with the 2 or 3 doors and about
6 feet tall and 2 feet deep.  There should be enough room to retrofit
some rack rails in there.  TV-2 style. (2X4s painted black and
equipment held in place with dry wall screws.)

[Repeater-Builder] Motorola welded rod yagis

[skipp025]

Motorhead (Motorola), Cellwave and now RFS make a 
very strong end-mounted yagi for 450-470 MHz 
operation. 

It's all welded Al Rod on a thick ~1 tube. 

I picked up what measures out to be a 418-420 MHz 
range version of this same type/style antenna. Anyone 
have the model number and the specs? ... or a 
location there-of?  

Once I ID the yagi, I'll make my drawings available 
to all (as done with the DB-408 antennas from before) 
to Mike for posting to the RB Web Page. 

Thanks for your replies...

[Repeater-Builder] mobile duplexers

[axe1990]

I have what I think is an old vhf mobile phone duplexer. It has four 
cavities. The cavities are marked with three as TX and one as RX. Can 
anyone tell me are these all pass type cavities ? Or could any of them 
be notch type ? This seems to be the common pattern of cavity set-up 
for these mobile phone duplexers.

Thanks

If it's the kind I'm thinking of it's a notch-only device, and
only works with lower powered TXs.  There is absolutely no
pass functionality, thereby allowing any and all nearby RF
complete and free access to the RX front end. This means
that they are only practical at a repeater site unless you
are the only system there.

The 4-cavity units come in both three-and-one and two-and-two
designs.  I've also seen 6-cavity units in four-and-two and
three-and-three arrangements.

[Repeater-Builder] Tait T-300 series VHF Repeater - Information Required, Narrow filters inside, want to use standard diviation for Ham Use

[Kevin Natalia]

Hi All,

I recently acquired a Tait T-300 VHF repeater unit. Looking at using it in 
one of our repeater installations.
Got everything working, and appeared to be putting out all the correct 
levels, power etc.
However, after a few days, I was advised that the audio seemed to be low on 
the out put.
I went up to the site and checked the audio going into the 
controller(RLC-3), and this seemed okay. Did not have a deviation meter, so was 
not able to check the output level, but by ear it sounded okay. Anyway it was 
still low.
Brought the modules down, and opened the modules. This is when I found out 
that inside the filter had the markings "21F 7.5 D H", which I worked out to be 
21.4 IF, and 7.5 deviation.
I would like to know if I can somehow make it, so it can be used as one of 
our ham repeaters? If so, what do I have to do to make this work as 
needed?
And any other info that might be of help?

Regards and Thanks

Kevin. ZL1KFM.

Re: [Repeater-Builder] A Good 440 Anttena

[Leon Ingerick]

I would suggest the Decibel Products DB-408 or the
DB-420 antenna.. I have two DB-420's and 11 DB-408 in
service in the 440 band and they all work great.. They
are all the 450-470 mhz model.. Put them up once and
walk away..

Re: [Repeater-Builder] Tait T-300 series VHF Repeater - Information Required, Narrow filters inside, want to use standard diviation for Ham Use

[Matt]

Hi Kevin,

I use a Tait 300 series on my 6m 
repeater.

I have found that although the filter is 
technically correct for the 12.5KHz spec ( i.e 2.5KHz deviation max ) that few 
if any Amateur rigs are setup for this correctly out of the box. 

I have changed the filters in all of mine for 15KHz 
bandwidth filters. I know the purists will say that my signal to noise ratio is 
now not as good but it didn't make much difference in reality as 6m is such a 
noisy band anyhow.

However the up side is that now all the users sound 
great. Before I changed the filter many stations sounded distorted due to the 
edges of the filter being exceeded by their deviation.

Other than that, I have had no difficulty with the 
Taits at all, and used them for many years in my job as PMR 
technician.

So to summarise, I would say all you needed to do 
is to change this filter - you might be able to find a filter that is out of 
something else that will fit as Tait no longer support the 300 series. I 
approached them to get a 15KHz filter and that's when I found that out! I ended 
up using a STC filter from a Pye R400 UHF link rx.

Check out the pictures on my web site www.gb3fh.org.uk You'll spot the 300's 
there!

Hope this helps.

Re: [Repeater-Builder] Tait T-300 series VHF Repeater - Information Required, Narrow filters inside, want to use standard diviation for Ham Use

[Gareth Bennett]

Hi there;
 You have got a T300 Narrowband 
repeater (12.5 KHz Channel spacing). The IF Filter that you have is for 7.5 KHz 
bandwidth rather than 15 KHz (Which is for 25 KHz Channel spacing).
 Unfortunately you have the last 
of the T355 receiver's and these were double conversion with 21.4 MHz IF's 
compared to the 10.7 MHz IF's.
 I may be in a position to get 
you some 25 KHz T300's as I am aware of some that are being replaced by T800 
repeaters if you are interested.
 We used to go the other way with 
the older gear and whip in a xtal filter from the old Pye/Philips P135 Falcons

  Subject: [Repeater-Builder] Tait T-300 
  series VHF Repeater - Information Required, Narrow filters inside, want to use 
  standard diviation for Ham Use
  
  Hi All,
  
  I recently acquired a Tait T-300 VHF repeater unit. Looking at using it 
  in one of our repeater installations.
  Got everything working, and appeared to be putting out all the correct 
  levels, power etc.
  However, after a few days, I was advised that the audio seemed to be low 
  on the out put.
  I went up to the site and checked the audio going into the 
  controller(RLC-3), and this seemed okay. Did not have a deviation meter, so 
  was not able to check the output level, but by ear it sounded okay. Anyway it 
  was still low.
  Brought the modules down, and opened the modules. This is when I found 
  out that inside the filter had the markings "21F 7.5 D H", which I worked out 
  to be 21.4 IF, and 7.5 deviation.
  I would like to know if I can somehow make it, so it can be used as one 
  of our ham repeaters? If so, what do I have to do to make this work as 
  needed?
  And any other info that might be of help?
  
  Regards and Thanks
  
  Kevin. ZL1KFM.

Re: [Repeater-Builder] A Good 440 Anttena

[Chuck Kelsey]

I think my wife stole my Decibel catalog ;-)

The 413 is 8 elements and the 411 is 4, right?

If you're going to side mount on a tower, use either. If you're going to top 
mount, I prefer the shorter 411. The longer antennas have too much flex in 
the wind to top mount, in my opinion. Others will disagree, but that would 
be my choice.

Right on the money... the 420 end mounted at the top 
of a tower has enough end torque to actually flex a 
Rohn 55 section (in a 35mph) quite a bit.  Enough 
to make me really nervous. 

You can in-line the dipoles of a DB-408 per 
Decibels information to obtain a sort of colinear 
pattern, which is bi-directional to an extent.  

Side mounted, the 420 kicks fanny (a nice way of 
saying butt), but you really don't want that much 
antenna at the top of a tall skinny tower. 

The DB-411 is a pretty nice 4 dipole unit, it will 
give you a nice directional lobe in the desired 
direction. It's also a good preformance/gain vs 
length antenna. 

cheers,
skipp

  THE CHANGING OF THE GUARD:  FRED DEEG, N6FD - S.K.
 
  Anyone who was licensed in the 1960's and 70's when the first
  off-shore ham gear started to show up in the U-S market may well
  remember the name Fred Deeg and the call sign N6FD.  Fred, the former
  K6AEH,  was among the very first to represent  radio giants like
  Standard, Kokosai and Yaesu.  He was responsible for bringing the
  first Standard Radio built ham radio band only 2 meter H-T to the
  United Sates in the late 1960's.  And it was during his tenure
  Yaesu that he coined the advertising catch phrase The Radio.
  This is a term that Yaesu's current parent corporation -- 
  Vertex-Standard -- still occasionally uses in some advertising today.
 
  Fred was also an FM and repeater pioneer in the Los Angeles area.
  Back in the 1960's with the Pallisades Amateur Radio Club of Culver
  Citry, he helped to establish the famed 146.61 MHz system that he
  nick-named the good-guy machine.  And in the 1980's he put together
  the Ham Master Tie System which was one of the nations earliest 220
  MHz interlinked repeater networks.  He also helped to organize the
  funding for the California deligation that flew to Washington for the
  meeting that lead the FCC to do away with much of the restrictive
  repeater over-regulation of the middle-1970's.
 
  A few years ago, Fred retired.  He and his wife Marsha, WA6CUF,
  retired to Anacortes, Washington where Fred died on Christmas Day,
  2004, after succumbing to cancer of the esophagus.   It was not until
  the curerent issue of QST carried his name and call in the Silent Keys
  column that his friends world-wide learned of his passing.  Fred was
  only age 60 and will be missed.  (WA6KLA, K7VC, WA6ILQ, others)

   Fred built the original 146.61 MHz in / 147.33 MHz out repeater
  (later became the 146.01/146.61 MHz).  He built the first repeater
  out of Motorola tube receiver and transmitter strips from my garage.

   That was way before the club bought the new (then) Motorola Micor
  repeater.

Re: [Repeater-Builder] A Good 440 Anttena

[Richard D. Reese]

Chuck is correct.  The 413 is 18 ft 4 inches long and is rated 12 dB gain 
and rated to survive 1/2 inch ice at 90 mph.

The 411 is 9 ft 5 inches long , 9 dB gain 112 mph wind with 1/2 inch radial 
ice.
The 408 is 6.6 dB gain and will survive with 1/2 ice at 85 mph.
The 420 is 9.2 dB gain 18 ft 1 inch long and rated to withstand 70 mph with 
1/2 inch ice.

They are all good in my opinion.  I have used them all including the DB-404 
and they have survived the NE Ohio winters.  even with the 420 top mounted 
on towers but there is a lot of flex at winds above 60 mph.  I never had an 
antenna bend but did have on installation where the 420 was top mounted and 
the pipe that it was clamped to bent during a storm with gusts in excess of 
70 mph.

As far as which antenna to use - It depends on the installation, HAAT, top 
mount, side mount, omni pattern, etc.

RE: [Repeater-Builder] Vertex VXR-7000 battery backup

[Daron Wilson]

I think the concern is that of many
trickle charge systems. They are designed to float the batteries and switch
over if needed. They are NOT designed to recharge a depleted battery bank.
All this is fine unless you lose power on the site for 48 hours and run your
batteries flat and then the power comes back on, and tries to charge them.
Ideally if you ran on batteries for some time, you would go to the site and
make sure they werent too low and/or charge them up with a real charger
prior to putting the float charger back on them. Also you could put a low
voltage dropout device in there that dropped the system prior to dipping the
batteries too low.



Good Luck!

Re: [Repeater-Builder] A Good 440 Anttena-And a Big Thanks to everyone!!!!

[TGundo 2003]

Well, I finished putting up my system today, consisting of a converted motorola mitrek (that old junk I converted, not built :) oy!) and a DB-420 fed with 7/8" heliax. Its mounted atop a water tower at 150 ft, 130' haat. I have had portables up to 15 miles away getting in well, one was 10 miles away on the ht inside the car down in whats known as an rf hole and he was full quieting. A pleasant suprise.

So oviously the 420 works well. I had the choice of a 408, but Skipp has that one now. I got the 420 as a "gift" so I chose to go with that. I see a few around here that have been up for quite a while, no bends in them. We will see what happens to ours after a few chicago storm seasons and winters.

A BIG thanks goes out to all on the list who helped out our project. ALL of the advise here is priceless and really aids us first timers! Kevin, keep it up!

Thanks again to all!
