The ones 'in the middle' tend to be used less, so that could be a
factor. People tend to use them from the low or high ends.
There are also some that are less likely to false, but I don't recall
which ones. It has to do with the likelihood of an error in the bits
matching other codes in a shift

On the subject of PL Encoder/Decoder: I was hoping that they
existed in a form factor that could plug into the MASTR II.
Failing that, I'll hardwire something in.

You are correct.but remember, the "Ign. Sense" line has to be connected to

Thanks! Thats the answer I've been searching for. Its a similar rig-up to that

Yes, the "Ign. Sense" line has actually been seen on "MOTRACS", and probably
furthur back than that vintage! Probably a good idea...keeps the battery

That was an auto ranging voltmeter. They were rather expensive at the time,
compared to nowadays. As I remember it you could select auto range, or lock
it in a particular range.

It's not a dumb question. Since a DPL code is simply a string of ones and
zeroes, the only possible reason that one code might be favored over another
is a DC bias resulting from too many ones or zeroes in sequence. But, the

i will drive them with an Ge Phoenix specially modify at 450 too 500 mw of

Yes he did build some for a few years. They were never a big seller as the
price was pretty high. They did work pretty well. It did not have a digital
display, only analog meters. There were lights that showed what range it was
on. You could read AC on one meter and DC on the other. Handy for some

Hey guys,
Need some input here. I'm putting together a public safety repeater for my
local FD. It's going to be really simple. Given the relyability factor,
we're going with a kenwood. Here's the million dollar question, i need some
input. How about a kenwood tkr750 or a tkr740. I've run sev

The Kenwood TKR-740 is their top-of-the-line repeater, and it is intended to
be used with a power amplifier. I have a TKR-740 that I have mated to a
Motorola Micor TLD1692D PA, and I don't think there is a better combination
on the planet. The TKR-740 can be set to put out from about 100 mW

Are the serial ports on a PCMCIA card or does the laptop treat the serial port
as a card? You may need some additional software known as a point enabler to
access it under DOS.
