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.

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

Problem is, they wouldn't sell that well. Most hams don't have interest in
it. There are pockets of activity in the metro areas, but in most parts of
the country, 900 is empty. Heck, 6-meter ham mobiles have been around for
years, yet 6 FM activity is pretty dismal.

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

Hmmm...
What if someone came up with a board which could be retrofitted to a Spectra to
give it ham-style programmability via front-panel controlsm, or even a separate
control head? It wouldn't be interesting to the big manufacturers, but then,
neither was the GLB Channelizer.

Been there, done that. There was no interest in the ham community. Why? It
required modifications that most were not willing to tackle. At the moment, the
name of the guy escapes me, but I did one of his modifications to a 6-meter
Delta-S several years ago. He has since given up on the idea,
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.

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.

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.
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

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
Or if the micro was NLA, use the info as a basis for programming a new
one. As long as you knew what line did what, I'm sure it could be revived.

I don't know anything about programming the chip, but am pretty sure you'd
need the source code in order to make changes. Joe programmed the chips and
wouldn't release the code - he didn't want someone to steal his idea.

Thanks for any input.

Take a pass on those... there are already 900 MHz Spectra radios out there

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
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.

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
