Re: [Repeater-Builder] Re: 900 meg Spectra radio

[MCH]

On the contrary, the docs were very enlightening.

Perhaps the reason there was little interest was the fact that it 
appears to make the radio 'single channel only', and I'm sure many 
people would have wanted to keep the multi-channel capability. But, as 
an add-on to the radio as-is, it would have been very interesting.

What microprocessor did he use? And are any still available?

Maybe that could change in light of the situation.

But, I was talking more about looking at the hardware and creating a new 
source for it.

Of course, if the original is still available, that would be fine, too.

[Repeater-Builder] Re: LDG voter, Hamtronics Tx and Rx, Pacific Research contoller.

[burkleoj]

Ben,
If you are considering purchasing the Hamtronics REP-200 repeater, I would 
spend my money on a Kenwood TKR750/850 series repeater. They are about the same 
price, but the Kenwood is a much better built piece of equipment and has a 
decent built-in controller for basic operation.

If you were looking to buy just the individual pieces from Hamtronics and put 
your own repeater chassis together, I would prefer to use just about any 
commercial equipment instead of those pieces. 

I am not sure what features you are looking for in the controller but there is 
a large amount of support available in the amateur community for Arcom, NHRC, 
CAT, ICS, and Link-Comm controllers. The Pacific Research Controller does not 
seem to be used much in our area but it looks like it will do most things a 
person would need.

Good luck with your project.

True 900 MHz radios are common enough.

I'd pass on them unless they are remote
mount and you can get them for really really
cheap (like one to two dollars a piece)
AND if the cables are't cut.  It seems that
every removal monkey just cuts the cable
in half and rips it out from each end.

Personally, I'd love to find a cable and B5 head
kit for a remote mount Spectra.

I know a couple more folks that would love to
convert a front mount Spectra to a remote mount.
With cars getting smaller and smaller, there
are probably a lot more folks out there that would
like to as well.

RE: [Repeater-Builder] Re: 900 meg Spectra radio

[Mark]

Joe,

Newer Spectra radios are capable of MPL (Multiple PL).  

Of course, you can only program 16 different PL/DPL codes, but it's better
than one.  This is what I have - I went through the list and chose the most
commonly used ones.  IIRC, this will give me access to about 85% of the 900
repeaters nationwide.

And put an external CTCSS/CDCSS encoder on it?

There are more tone/code combinations to fill 128 channels on a single
frequency.

Yes, but Joe's control head was frequency programmable on the fly as was the

There was, but it's all gone now. At one point a link to his site was posted 
on the Repeater Builder site. Joe made several posts to this list and became 
discouraged at the lack of interest. The documentation would be of no value 
as you need the programmed microprocessor chip to make it work.

K3JLS - The wayback machine has a bit of information:
http://web.archive.org/web/20050907131941/http://www.k3jls.com/

Although with the 128 channel slots, that would seem to cover the entire 900Mhz 
band plan

Re: [Repeater-Builder] Re: 900 meg Spectra radio

Interesting. I wonder if there is some tech info on this that is 
available. Any idea how much the cost was and what mods were required?

Or, perhaps some tech data on the synthesizer as far as what pins 
control the frequency, as well as any binary-to-frequency info.

Joe Burch was his name. It was a frequency agile control head that could be set 
up for most any type of synthesized commercial radio. You entered the frequency 
and tone via a keypad.

Ben,

Just curious here, but why wouldn't you use surplus, or even new commercial
gear for your repeater, versus the hamtronics equipment?  There is a TON of
surplus commercial gear out there that is 1, more robust, and 2, is much
more inexpensive.  For those who know me, it is no shock that I would
recommend commerical gear.  There is a wealth of information and help
available, and IMHO, the lowest of quality commercial gear, is far superior
to the highest grade amatuer gear.  I am sure I will get flack from the
Yaesu, Icom, and Alinco loyalists.  Just my opinion.  YMMV.

Re: [Repeater-Builder] 900 meg Spectra radio

[Nate Duehr]

That's the reason I asked.  There's a major manufacturer making a pretty 
decent 1.2 GHz radio (Icom ID-1) that costs $1000, and it's obviously 
also (besides doing FM) a D-STAR rig, and that distinction is making it 
sell to those with $1000 to burn on a digital mode... but a 900 MHz FM 
Analog with no "hook" feature to pull people in, I think would sell 
dismally, and therefore would have to cost at least that much...

Hi all.
I am thinking about implimenting the above products into a repeater. I would 
like some comments from those that have experience with any of them. Also, does 
anyone have any for sale? This is for a UHF machine and would use the newer 
Hamtronics components. 
Thanks and 73

[Repeater-Builder] Re: Manual for HAL ID-1000?

[Greg Beat]

I submitted to Repeater Builders (WA6ILQ) the Programming Section (IV.) of the 
HAL ID-1A REPEATER IDENTIFIER Manual.
This section describes how to properly solder the diodes (1N270) in the DASH 
Matrix and SPACE Matrix of the ID-1A 
for the creation of a CW message (Repeater ID).

This section of the 1972 HAL ID-1A manual was OCR/Image scanned, cleaned up, 
placed into MS Word format and 
then an Adobe Acrobat (PDF) created.  This document is high quality, easy to 
read, and current document standards. 
The 1972 copyright is retained by HAL Communications (Bill Henry, president) 
and noted on the footer of
the refreshed document.

I did add one UPDATE to the refreshed document.  The 1N270 germanium diode is 
no longer manufactured.

The Central Semiconductor CDSH270, a Silicon Schottky diode specifically 
designed to replace Germanium diodes 
like the 1N270, 1N277, etc. is a recommended replacement.
This newer technology provides lower forward voltage, lower leakage, faster 
switching speed, and a more robust package.
Mouser part # 610-CDSH270 is a reliable source for this diode at about 25 cents 
each (2008).


The HAL ID-1000 uses a DIFFERENT Diode Matrix format, SO this manual excerpt is 
not helpful for that newer CW ID model.

You might have one or more electrolytic capacitors which have dried out. 
I think the last Mitrek rolled off the line before I was born, which is 
longer ago than I'd like to admit.

[Repeater-Builder] Mitrek problem

[kernkampj]

Recently I had a problem with a Mitrek radio,  The RX channel element would not 
reliably start oscillating on power-up.  In my experimenting, I discovered that 
the problem related to the power supply I used.

I had four power sources - two linear supplies, one switcher, and a battery.  
One of the linears and the battery worked fine.  The other linear and the 
switcher created the non-start problem. 

I finally noticed that the radio has two internal power sources for the channel 
element (9.5 Reg and 9.5 switched), and wondered if the timing of the two 
sources could be the problem.  So I slowed down the 9.5 switched source, and 
that cured it.  The channel element now starts every time from any of the power 
supplies.

For those interested, I added a 100uF cap from the base of Q1 (the receiver 
9.5V Switched supply) to ground.  This slowed down the voltage output of the 
9.5 switched source.

[Repeater-Builder] Vertex FTL-1011 6 meter conversion

[rush8001]

Hello, Hoping someone can help me with tuning up my 4 channel Vertex FTL-1011 
(42-50 mhz split) to 6 meters. I
understand I have to re-adjust the VCO and front end for better sensitivity. If 
anyone can explain the process, or provide any info, it would be a great help.

I was hoping to add this to my Motorola GR500 setup, as a part time link.

Thanks

Rob
