 The one labeled Volume.

 Sorry, couldn't resist.

 Seriously, I don't know what you mean.  You mean Tx deviation?  It's
 adjusted in software.

Re: [inbox] Re: [Repeater-Builder] Sinclair VHF Duplexer

2005-12-14 Thread Ellen Engle





OK, If I read your post correctly you want to increase the spacing to more 
than 5 MHz for use with a VHF-Hi Business system.

Since this is a mobile low power notch only duplexer it will depend on what 
spacing you are trying to achieve. If close to 5 MHz, like 5.5 to 6 MHz, I 
would try and see what can be done. If more than 6 MHz you probably want 
to forget it and get another candidate. Also you don't give a lot of info 
about conditions where it will be used so even if it would tune up properly the 
construction may not be appropriate for your intended use.

do a google search for him

He was a Sinclair  person and still does this work .. he is the one 
who made my 220 duplexer

We had a 'mobile' duplexer to him about 3 weeks ago , and he was 
able to move it into the 'ham' UHF band for us with some work ( 
took at 1/2 hour and it was good to go )

Sorry I don't have his email right here but his website has his phone

[Repeater-Builder] Some goodies for sale

2005-12-14 Thread Jed Barton
Hey guys,
Because of some changes in repeater sights, I've got some clutter taking
up more space in my shack, that I'm sure can be useful to some people.
I have the following items for sale.
Prices are all open ended, so email privately.

2 Cat 1000 controllers
These 2 controllers are like brand new.
In fact, one of them only has about 5 hours on it.
Each one of them includes the rack mount.


1 Cat 300DX with the RBS1000 remote base interface switch

1 Link-comm rlc2 controller with the DVR and phone patch, and the rack
mount

2 kenwood TK801s
2 GE Phoenix's

1 UHF motorola mitrek (will work great for a repeater)

Because I'm doing a ton of upgrades, the controllers were especially
occupying space.
Any takers?
I'm open to ideas for prices.

Thanks,

 * Hello All,
 
 I am in the process of brute force hacking a Kenwood TKR-820 into the ham
 bands. No one seems to be forth coming with a schematic of the KPT-50 so I
 have a cable ghettoed to the back of this laptop going to the serial eeprom
 on the front board.
 
  So far I have been able to program the dual synthisizers to the test
 frequency of 446.3TX and 441.3RX, simple formula,  Target frequency in Khz
 (446300) minus 21400 divided by 12.5 then converted to hexidecimal for both
 synthisizers.

The reason is that it has it's own uP in it with custom software. So a 
scehmatic will not allow you to build your own.
Either a KPT-20 or KPT-50 is need to program those. No way around it.
Unless you want to go through the trouble of reverse engineering the 
code in the EEPROM. If you're successful at that though, write up what 
you get and post it to RB!

 Bernd,
 
 I don't know if the tone boards you have are the same as are in one of 
 mine, but the way I figured out the switch settings was to look at the 
 encode frequency and switch them until I found the frequency I wanted. 
 The encode and decode will work from around 50Hz up to at least 2KHz. 
 The switches are binary weighted.
 
 Sorry I don't have any detailed info on them.

[Repeater-Builder] Re: Kenwood TKR-820

2005-12-14 Thread skipp025
Wow... sounds like a fun project if one had all the 
time to get around having the kpt-50.  There are a 
number of people wanting to get around the kpt-50 
requirement with a basic rib type programmer. 

But I've always removed the eeprom and used the 
the kpt-50 along with the kpg-21d software to keep 
from using the kpt-50 key-pad again. I believe 
the sub tone/dcs information is kept in the eeprom.

If you're local to me near Sacramento, I'll program 
your repeater to the ham bands for free.  If you 
really needed to get the eprom done, I'd even help 
you by mail. 

I also keep the kpt-50 in stock (I'm an Authorized 
Kenwood Dealer).  Email me direct if you want more 
information. 

I've run the tkr-720 and tkr-820 in both carrier squelch, 
with a tone panel (external) and with a trunking controller. 

The factory repeater board doesn't generate true 
reverse burst. Like other mfgrs did... the tone is 
often shut off before the transmitter drops and the 
detector tries to close the audio of before the tx 
drops. 

Aside from some of my personal connection notes, one 
of the better external controller mods was posted 
by Mike a short time back. You simply unplug the the 
repeater board and run a number of small plug jumpers 
as directed in the information.  

Yes, if you make up a kpt-50 work around, it will be 
quite popular. 

Hope that helps a bit.

the ham
  bands. No one seems to be forth coming with a schematic of the
KPT-50 so I
  have a cable ghettoed to the back of this laptop going to the
serial eeprom
  on the front board.
  
   So far I have been able to program the dual synthisizers to the test
  frequency of 446.3TX and 441.3RX, simple formula,  Target
frequency in Khz
  (446300) minus 21400 divided by 12.5 then converted to hexidecimal
for both
  synthisizers.
 
 The reason is that it has it's own uP in it with custom software. So a 
 scehmatic will not allow you to build your own.
 Either a KPT-20 or KPT-50 is need to program those. No way around it.
 Unless you want to go through the trouble of reverse engineering the 
 code in the EEPROM. If you're successful at that though, write up what 
 you get and post it to RB!

Subject: [Repeater-Builder] Some goodies for sale


Hey guys,
Because of some changes in repeater sights, I've got some clutter taking
up more space in my shack, that I'm sure can be useful to some people.
I have the following items for sale.
Prices are all open ended, so email privately.

2 Cat 1000 controllers
These 2 controllers are like brand new.
In fact, one of them only has about 5 hours on it.
Each one of them includes the rack mount.


1 Cat 300DX with the RBS1000 remote base interface switch

1 Link-comm rlc2 controller with the DVR and phone patch, and the rack
mount

2 kenwood TK801s
2 GE Phoenix's

1 UHF motorola mitrek (will work great for a repeater)

Because I'm doing a ton of upgrades, the controllers were especially
occupying space.
Any takers?
I'm open to ideas for prices.

Thanks,
Jed.n1jbc

Oh, I believe they're locking out the analog receiver in digital operation.

If the digital transmitter drops, then it's a free-for-all first-come,
first-served digital or analog at that point, but the system's quiet

I have not gotten the internal controller to activate the repeater, I
am suspecting that it is waiting for a DQT code (Digital PL) to
activate. 

I tweaked the VCO's for 3 volts not knowing any better, I will readjust them tonight. 

I built a simple interface for the serial EEPROM out of a few resistors
and zener diodes. At the moment it is just hard wired to some vias I
saw coming from the programming plug. I will rebuild my interface
tonight to have a 8 pin socket and +5 volt regulator so the chips can
be programed out side the rig and see whats in the other chip.

Looking at the schematic, I have no idea how they are getting data over
to the EEPROM on the signalling board, there apears to be no
connections to the programming plug. Also there is an awful lot
of fire power on that board just for the CTCSS encode and decode, you
would think they would have put a CW IDer in there. Looks like there is
room enough left over on the tray for a smaller controller such as the
NHRC-Micro and TCX-12.

The company that had it previous didn't take advantage of the sweet
mounting method for the duplexer and it was on the top cover with
double sided stickey tape. $3 at a hardware store will yield a
brass strip and sheet metal screws to take care of the mecahnics, and
some double shielded coax and BNC connectors should cure the RF side.

Hi Jim, 

There was a debate about the reverse being a 
true Motorola type Reverse-Burst. It only seemed 
to matter if you were running the true reverse 
burst decoder with the reed stall Motorola 
parameters values. 

Never mattered to me much... the goal was to 
reduce or elminate the users tx un-key static 
crash. 

I got tired of fighting different reverse phase 
formal formats for so many different radios  
receivers. 

Extending out the rptr tx hang time without a 
sub tone has been a poor mans way to deal with 
no reverse burst function. I put in one of the 
original comm spec RB-1 modules (diagram avail 
on the RB web site) and some radio decoders liked 
it... some didn't. So I added the extended no 
sub tone time and everyone is for the most part 
happy. 

I use the molex jack on the back for external 
controllers and tone panels... the hook-up is different 
for each.  As a simple ID'er, I've used the Autocode 
module many times.  It's cheap and an easy board 
to add... no other parts are required other than 
the molex plug  pins.  

The first time you do any tkr repeater connection... 
you quickly learn to scratch your head in wonder. 

cheers,
skipp

If you pull the tone chip, it should repeat CSQ. Make sure the rpt

You're right-there isn't. The tone chip is programmed by removing it and 
plugging it into the programmer, either the KPT-20 or -50. And that's 
the only info it has is the 8 encode/decode tones/codes.

 Also there is an awful lot of fire power on that
 board just for the CTCSS encode and decode, you would think they would have
 put a CW IDer in there.

You forget-this is pre-1990 vintage equipment. It only looks like there 
is a lot of hp! It is the whole controller though. It does repeat audio 
gating, hang time, TOT, as well as encode/decode. Oh yeah, the repeat 
squelch control is on that board too. The front panel sq control has no 
effect on repeat.
I guess there wasn't much of a call for an internal ID at the time. I 
can't think of any other commercially-made desktop repeater that had an 
ID'er built-in from that vintage, either. To get that, you had to go to 
an MSF-5000 or MastrIIe/MastrIII size box. In fact, most of the desktop 
repeaters of that vintage were crystal controlled!

  Looks like there is room enough left over on the
 tray for a smaller controller such as the NHRC-Micro and TCX-12.

Yup, most likely. I know putting something like an ID-8 in was a snap. 
Almost enought room for 2 of 'em, not that there's a reason to have two...

 
 The company that had it previous didn't take advantage of the sweet mounting

Wow...how revolting. And the repeater CAME with hardware to mount a 
duplexer inside. The holes are even tapped already!

for the Freq. and CTCSS EEprom.. The 1st half of the file is the
image for the Freq. EEprom and the 2nd half of the KPG21D file
is the Image of the CTCSS EEprom file.. 

I realize binary file editing to not for everyone, but it's not
as hard as everyone makes it out to be either..

I also want to create a 'EZ-Prog' type exe that will create the

 Some of the low end talkies do not respond to reverse burst.  No tone on
tail works for most everyone, but not nearly as 'clean' as reverse burst -
also there are several different amounts of phase shift with reverse burst.

Pete,

That is some damn fine information there. I only wish I had it last night. About the only thing that is different in the 820 is the divde radio is .0125 instead of .005Currently I am using a program called pony prog whichthe serialinterface I am usingissimilar to the one shown on this website, I will redothe schematic with one that is guarenteed towork though and doesn't need any fancy regulators. AlsoI am using some Hex editor I found on google, It is like the first link when you type in hex editor.


It may be possible to add the missing channel controls and jumper the control chip from repeater to base mode so thenthe repeater could QSY, not much say 100kHz to allow the duplexer to functionbut more importantly change PL tones remotely to allow Carrier access or different CTCSS tones. I think the TKR-850 series does this already but that may be a pretty sweet mod for the x20 series.

Gerritsen Found Guilty of All 6 Federal Counts!!

Today 12-09-05, at approx 10:05 AM, at the Roybal Federal Building in 
Downtown Los Angeles, the 7 women and 5 men jury returned with a unanimous 
verdict on the Gerritsen Federal case after approx 1 1/2 hours of 
deliberation, and found Jack Gerritsen (Ex-KG6IRO) GUILTY on all 6 Federal 
counts.

Jack was taken into immediate custody by the U.S. Federal Marshals.

Verdict is as follows:

Count 1, U.S. Title 18, Section 1362, Transmit on a Government Freq; GUILTY

Count 2, U.S. Title 47, Sections 333, 501, Malicious interference; GUILTY

Count 3, U.S. Title 47, Sections 333, 501, Malicious interference; GUILTY

Count 4, U.S. Title 47, Sections 301, 501, Transmitting without a License; 
GUILTY

Count 5, U.S. Title 47, Sections 301, 501, Transmitting without a License; 
GUILTY

Count 6, U.S. Title 47, Sections 301, 501, Transmitting without a License; 
GUILTY

Jack objected to the immediate incarceration, but the Judge said these are 
FEDERAL Felonies, and he has been found guilty, and will be remanded.

Sentencing will be on March 6, 2006 at 1:30 P.M. at the same court, Roybal 
Federal Court, 255 E. Temple St, Los Angeles, Room 850.

The reason for the delay in sentencing is for Mr. Gerritsen to be 
interviewed by the Federal Probation Dept., which is standard practice 
prior to any sentencing.

Re: [Repeater-Builder] FS: RCA Super Carfone 500 Series

2005-12-14 Thread Mark A. Holman

I have available for sale several RCA 500 series Super Carfone UHF 
transceivers. These include the receiver and transmitter strips with the 
vacuum tube power amplifiers,  mobile mounts (if you want them). The amps 
are good for about 90 watts output in FM service. These units are used, old 
stock removed from commercial service many years ago and stored in a 
climate controlled environment. They are not tested, presumed working. They 
are good for making repeaters, beacon transmitters, repeater receivers, 
control receivers, power amplifiers, organ donors for other RCA gear, and 
as 30 lb. (approx.) anchors for small water born craft.
Asking $25 each plus shipping from 37212. Contact me via email at K4IDC at 
comcast dot net.

Thanks,
