[Repeater-Builder] 1272 Mhz Preamp

[Steven Samuel Bosshard (NU5D)]

I am looking for a supplier of low noise high performance receiver 
preamps and preselectors for a 1272.100 receiver.  I have contacted one 
of the suppliers on the repeater builder information page, but I placed 
the order in August and cannot get anything but an answering machine and 
no returned calls.

First hand information would be nice.

[Repeater-Builder] Lloyd is Well was Cable Lengths

[Steven Samuel Bosshard (NU5D)]

Just a few minutes ago I had a really nice chat with Lloyd Alcorn, one 
of the three founders of Wacom Products.  Lloyd's background includes 
being a professional engineer working for Decibel Products and helped 
design the DB 222 folded dipole antenna.  Lloyd Alcorn, Larry Bush 
(W5NCD) and Kit Parsons (deceased) founded Wacom Products and for many 
years Wacom existed in a couple of service bays at Waco Communications, 
an RCC and Land Mobile shop in Waco.  I worked for Waco Communications 
from 1975 thru 1981 in the RCC end of things but had much contact with 
the Wacom folks even after I went into business for myself in 1985.

According to Lloyd,  the cable length between a duplexer and an inline 
cavity filter and the receiver makes little or no difference.  The 
culprit to beware of is - radiation from the receiver toward the inline 
cavity filter.  The LO is the primary source of this radiation, but 
there may also be other signals generated by the receiver.  This low 
level signal sets up standing waves between the receiver and the cavity 
filter and may cause some black magic to enter into the equation.  
Changing the cable length may help reduce the effects of stray radiation 
between the receiver and the cavity should this occur.

Placing a band pass cavity between the receiver and the duplexer will 
make no difference at all if the interfering signal is on the receive 
frequency.

Now the transmitter.  Again most but not all of the time, the cable 
length between the transmitter and the duplexer will make no difference, 
EXCEPT that the transmitter may have other out of band energy that again 
sets up standing waves between the transmitter and the duplexer and 
these unwanted signals bounce back and forward between the transmitter 
PA and the duplexer and intensify.  This is where a magic cable length 
can help.  Also an isolator can help not withstanding the isolator does 
create it's own set of problems.

Lloyd still lives and Waco.  I promised NOT to give his phone number and 
he said he is not in hiding.  He is still very active, golfing from time 
to time and serving in the Baptist Church there in Waco.  His health is 
good, except for the standard maladies of getting older.  He did mention 
that Kit's demise came quickly, having talked with Kit some months 
earlier and Kit made no mention of an illness.

Lloyd gives his best regards to all the folks he worked with over the 
years - said when they get up in the morning, sometime they go back to 
bed - don't have to go to work.

Thanks Mark, I needed a good chuckle - been on a mower the last couple of hours 
- at work we have an Ericsson Data Gateway - EDG that is the go between the 
EDACS trunked radio system and the records management system - Seems like it

[Repeater-Builder] DStar Repeater Pics

[Steven Samuel Bosshard \(NU5D\)]

I just snapped a couple of pix of the Temple, Texas DSTAR Installation.  The
Gateway is non-functional waiting on software from Icom, but the rest of the
stuff is hot and ready.  I added an extra 5" 3/4 Wavelength cavity in front
of the receiver (beige DB Products can in the last picture).  Using a dual
band fiberglass ham quality antenna (till I get time to hang another DB420)
on a 175 ft Rohn 45 G fed with 1/2" LMR 500.  The WP639 is one of the early
ones built by Lloyd Alcorn and tuned by John Elliot back around 1985 or so.
The extra cavity is to help with overload from a 5 channel 450 Mhz LTR
system and a 5 Channel 856 Mhz LTR system on the same tower.  The local ISP
has a point of presence on this tower with a semi broadband connection back
to his demarc - I have a nic installed in his linux switch - kinda like
having a friend at the factory, so to speak.  In a nutshell, 25 Watt
repeater running D-STAR JARL format with a Dell computer for the Gateway, in
a 6.25 Khz Channel with room for 2M and 23cm.

Re: [Repeater-Builder] tower tips..

[Steven Samuel Bosshard \(NU5D\)]

I totally mis-read you earlier post.  Forgive my off key response.

First the benefits to the community and the tower owner.

Second no risk to the tower owner - qualified personnel, bonded and insured.

See if any of the tower owners folks are hams, or if there are already hams
with equipment installed, see if you can work together.

No interference to the owner's equipment or services.

See if you can get the owner's contractor involved - Yep, we use old so and
so at Tower Tech to do our work.

Use of tower can count as a charitable donation to the 503C3 entity needing
the tower.

Just a few - I wish you best luck.  Had one tower owner that would not say
no.  Trouble is he would not say yes either - I finally gave up.

Re: [Repeater-Builder] tower tips..

[Steven Samuel Bosshard \(NU5D\)]

Stay away from power lines.  Be sure the tower is safe to climb BEFORE you 
climb.  Use proper safety apparatus.  If you are inexperienced, get someone 
with experience to help.

Re: [Repeater-Builder] 3 minute timeout. FCC regulation or myth

[Steven Samuel Bosshard \(NU5D\)]

I was just thinking, in public safety the typical transmisssion is much less
than 10 seconds.  30 seconds would be long, an 60 seconds almost unheard of.

60 seconds should be adequate for almost any amateur radio 'shared repeater'
operation.  If the OM needs more time, make a short pause (maybe see if
there is something "important" needing to be broadcast), and then resume.
This is more a good operating technique than anything to do with rules, kind
of like not carrying on QSO's on a calling channel or monitoring both
frequencies when trying to work Scarborough Island split on 20 Meters

Re: [Repeater-Builder] New repeater Motorola or MA/COM

Mike, yours is a very good comment, Moto / MA/COM.  Probably the best
approach would be to compare specifications, and take a good look at each
product for serviceablilty.  Don't forget EF Johnson - I have 10 or 15 of
their VX series, and 5 or 6 M3, and a handful of Kenwood TKR820's and such
that I use in my own LTR trunking systems.

By large and far, modern equipment has been very trouble free.  In my real
life I maintain 78 MA/COM M3, 800 Mhz Edacs repeaters, 4 Sites, 19 channels
per site, simulcast, with a couple of NPSPAC channels for interoperability.

I do know how the Maytag man feels.

Re: [Repeater-Builder] Repeating D-Star

[Steven Samuel Bosshard \(NU5D\)]

"non-open standards" have always been legal. The point is whether you
need a special code or other key to receive it, ie, can the FCC pick up

I remember once upon a time a couple of hams were running RTTY on 2M using a
non-ascii code.  Back then the take was that as long as both parties kept a
record of the coding being used and had same readily available for
inspection in their station records that it was OK.  That and 42cents will
buy you a senior coffee at McDonalds, UNLESS you bring doughnuts on Fridays,
and then my sweetheart, the manager buys the coffee.

Probably better to move on to coffee and pastries and leave the laws to the

Re: [Repeater-Builder] Repeating D-Star

[Steven Samuel Bosshard \(NU5D\)]

I ran an AOR DV unit thru a plain old 2M voice repeater a few years ago.
Not withstanding the faults with the AOR like sync and re-entry, the audio
is GREATTT.  They do lots of digital enhancements and to my poor ears
the fidelity is just awesome, and their 36 carrier scheme will fit into a
plain old voice channel, on ssb, though, it is not interference tolerant and
can be really frustrating once sync is lost.

Re: [Repeater-Builder] Service Monitors with D-Star

[Steven Samuel Bosshard \(NU5D\)]

I believe I would ask for a 9.6 kb/s digital voice repeater coordination (or
maybe 4.8 kb/s) occupying a 10 khz or 20 khz bandwidth and let the
coordinators sort it out.  Be it DSTAR, P25, AOR DV (this works pretty nice
on an FM repeater) Alinco's format or some new and yet to be decided format,
it should not make the coordinator any difference.  I don't believe the FCC
asks whether the user in public safety is running P25 or M/A COM ProVoice.

Re: [Repeater-Builder] Tuning duplexers with sweep generator?

Re: [Repeater-Builder] repeater problems, duplexer etc.

[Steven Samuel Bosshard \(NU5D\)]

In the days before the cushman ce50tg, I used an FM10CS with a bearcat
scanner to set pass and reject on BpBr duplexers.  Be sure and use a 50 Ohm
10 db attenuator on each port to normalize mismatch between the duplexer
port and the antenna port on the bearcat, or the generator and the duplexer.
Also terminate the unused port.  This is not a highly precise way to do the
job, but in a pinch this will work.  Of course you don't just routinely go
out ant tweak cavity duplexers, this is only when there is a reason.

Best luck,  Steve NU5D

Re: [Repeater-Builder] Re: Antenna gain specs

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

[Steven Samuel Bosshard \(NU5D\)]

Hello Dave,

If you really want tears in your eyes, I was in Wacom's Plant a few years
ago visiting - they were about 75 km from my home, and they had the entire
packaging and testing area filled with 70mhz duplexers - They had a contract
to provide duplexers to a European Lottery operator, and they used the band
to convey ticket sales and lottery information.  There must have been over
100, 2 72 Mhz duplexers being made ready for shipping.

I was dead serious about the aluminum irrigation pipe.  They had a local
electroplating firm cadmium plate the pipe, then silver plate, until our
natural resource commission shut down the electroplating company - too many
dead fish in the Brazos.

How the Brazos river got it's name is another story,  Anyhow, I don't doubt
the use of aluminum kegs, and that some folks have had misery, and others
success.  Lloyd Alcorn (one of the founders of Wacom) always refered to
duplexer design as black magic.  BTW most of the Wacom Team came from
Decibel Products in Dallas, Texas.  Lloyd designed the DB224 antenna there.
Gene Mulderik, Daylon Johnson, and several others came from DB Products.

When I had a 6M FM repeater I used 2, single folded dipole antennas, with 30
m vertical seperation, and took the preselector out of a junk motrac mobile
for extra front end protection - the repeater worked OK and mobiles out 200
km could work it, (the antenna was 600m above ground).  In 1980, there was
not much 6M FM activity in Central Texas.

BTW - are many of ur friends operating 60M?  I am looking to sked for a
US/UK contact on 5403.5 sometime in the wee hours of the morning here.

Best 73, good luck, happy new year, and heavy on the INVAR alloy.  Steve

Re: re re re re re re [Repeater-Builder] Re: how to build a very simple repeater

[Steven Samuel Bosshard \(NU5D\)]

For once and for all, 10 years ago I would have cluged together a simple COR
circuit with a hang time capacitor for keying and hook loudspeaker audio to
mic input thru a pad - NO MORE.

BUY a simple controller from any of a number of places check the internet -
do a google search - hook it up according to their instructions and get on
with life.  If you have trouble, email the folks who sold you the
controller.  You get hang time, audio coupling, time out timer, control
receiver input, morse ID and other features too numerous to mention, all for
less than $100 (some less than $50)

Consider the purchase of the ARRL Handbook or ARRL FM and Repeaters for more
detailed information.  If this is too difficult find a fellow ham in your
community that might help you - there should be at least one other ham who
is willing - why else have a repeater?  A bottle of good Scotch or Irish
whiskey should be suitable enticement.

Re: [Repeater-Builder] SLOPER

[Steven Samuel Bosshard \(NU5D\)]

If you really want to have some fun, attach a doublet to your tower.  One end 
thru an insulator at the top, and the other end thru an insulator near the 
bottom.  Use 450 Ohm line to feed it in the center and use a rope to pull it 
away from the tower to form a 90 degree (thereabouts) included angle.  This has 
some resemblance to a K3LR vertical 160 M antenna.  Mine is 2 lengths of 120 ft 
each on a 180 ft self supporting tower.  The antenna is oriented about 15 
degrees from true North - Nice 75M into Europe.  sb

[Repeater-Builder] Extra Super Hams

[Steven Samuel Bosshard \(NU5D\)]

Hey, got a couple here that come close.  W5POG, Poor Old George Erickson
celebrated 70 years as a ham radio operator yesterday.  Was first licensed
at age 14.  Don't know what celebrate means at age 84 but hope to find out.
Also Arden Clinger, W5CCD truned 90 late last year.  Both are reasonably
active and lucent.  Maybe these guys could be grandfathered for years of
service.

Re: [Repeater-Builder] Re: old mobile telephone systems

[Steven Samuel Bosshard \(NU5D\)]

Regarding RCC Channels, some system operators use the VHF and UHF
mobilephone channels for LTR trunking with interconnect.  This is permitted
under FCC rules except there is more reporting to the commission.  I started
in 1975 maintaining a GE IMTS system and also used a SECODE 2805 / VP1
system.  Imagine the radio drawing 2 amperes in standby, either the Motrac
with a 5894 filament and VP1 head, or the Mot T1433 Solid State with scads
of pnp transistors and a FACTS (Fully automated car telephone system)
Control head.  There was also a Rydax system in area...Dah Dee Dum(used
3 sequential tones for mobile dialing).

[Repeater-Builder] This is sure getting away from Enhancing the Art of the Mobile Relay

[Steven Samuel Bosshard \(NU5D\)]

Please indulge me one more tidbit.  Of off topic blather

The object of the Morse test is to demonstrate the ability to receive Morse
at 5 WPM, and then demonstrate comprehension.  Taking 45 minutes to
translate dots and dashes into text does not constitute the ability to
receive Morse at 5WPM.

In our VE sessions we announce in advance of the test that copying dots and
dashes is not permitted.  Other VE teams may allow this but this team does
not.

Regarding the comment to the effect "I can repair equipment but not operate
it."  I have been there myself.  I remained a tech for nearly 10 years and
had a lot of fun building repeaters, hanging antennas and experimenting.
Getting HF privilages does not immediately give you acceptance on the low
bands.  There is a rite of passage.  A good example would be the old men at
the coffee shop at a table to themselves.  You don't just grab a chair and
join them.  If you are careful and do a lot of listening, you might be
invited to join in.

Maybe not the best way to go about it, but this is the way it is.

Nice and to the point - I remember one of the VHF paging guys running
152.240 TX and receiving a 72 Mhz frequency with a single VHF antenna - he
added a band pass cavity in front of the 72Mhz receiver.  I ran a 147.280
repeater with a DB222 antenna and a 444.025 control radio on the same
antenna using a cross band coupler - I could afford some degradation in the
444.025 leg.

Re: [Repeater-Builder] Question

[Steven Samuel Bosshard \(NU5D\)]

I am using 2 GE phoenix SX UHF to tie 146.66 in Waco to 146.82 in Temple -
works FB.  I am sure the radius will work well for this task.  You may need
to protect the link radio from the 440 repeater transmitter and vice versa
with some cavity filters.  On 2M with a 440 control link and DB222 repeater
antenna, I have used a cross band coupler (one of the $25 cheapies) and run
both the 2m repeater PLUS the 440 link on the 2M antenna - just a thought.
Your milage may vary,
