CF-27's are probably as easy or easier to find and maybe
cheaper on Ebay... We have been using them for DOS radio RSS
programming for a long time... and generally the batteries cost more
than the laptop...many are 300/350 mhz processors, some 500-550
mhz... I have one (PIII 500) set up
Someone on the list asked what model Maxtracs I have available; here 'tis:
D37MWA5GB7AK (supposed to be a 30 watt radio; has large heat sink);
also marked HUF1076A
D27MWA5GB7AK (supposed to be a 12 watt radio; has small heat sink);
also marked HUF1075A
I have two each of these radios. I don't ha
Well, I'm not having much luck finding any of these... I tried a Google
search for "GC Tools" and for "Action electronics". Nada... Then I tried
going to Radio Shack and Digi-Key and searching for the item number - still
nothing. I even searched for "tuning tools". ARRGH!
Not that I need to hav
Jesse,
The short answer is that switching power supplies are significantly more
efficient than either linear or ferro-resonant power supplies over most of
their output range. At idle, switchers draw practically no current, whereas
linear and ferro-resonant supplies are always generating some heat
Thank you all for the advice. However, I have had no success with
using XP (or finding a DOS startup option..are you sure you're not
confusing XP with WIn98SE?). Maybe you have a dual boot setup?
Remember I need to use Moto RSS for the MT-1000 and Spectra. The only
machine I have had luck with
The laymans equation for power is
P=IE(cos(phase difference between I & E))
The cos of phase difference is the power factor. This could be hard to
determine by most who do not have the proper equipment.
However, power is not the voltage and current at a single point of time, but
the product
Hi James,
Probably nothing wrong with the Icom radios, but for your purposes I
would perhaps go with a used Motorola GR300 or similar repeater, or
even a couple of Maxtrac style radios with a simple delay cable for
tx keying and audio.
Program the radios with all of the event frequencies which

Would you please contact me off list I have some questions concerning
setting up sound cards and such for my repeater. You may contact me at:

There is no DOS startup internal to XP, however you can make a DOS
boot floppy from the Format A: floppy screen. The trick is you need
to partition the hard drive into 2 partitions 1 fat32 and pretty much
needs to be less than 1024 mb and the rest as NTFS for XP to
use...Copy all the DOS progra
I meant short installing by 1gb... 1024 mb... sorryor whatever
you can spare from the XP drive for DOS programs and that depends on
how many you have.. or wish to collect :-)

Ron,
You're absolutely correct. I deliberately avoided bringing the calculus
into the discussion, simply because many lay persons are not familiar with
it. The point I wanted to make is that true RMS power measurements require
that the voltage and current measurements that are being integrated m
I would think a disk manager with dual boot dos /xp or what ever as required
but you may need to set the bios correctly for the slow comms on the ports used
which is what I do here for programming things in my area of expertise although
I just boot to dos from xp ( which is almost a simulation)
This antenna was used for the old Bell Mobile Phone system on about
153 MHz. It was damaged by lightning and replaced. There is no
identification on it.
There are pictures in the Photos section, "Unknown Antenna"

Celwave? I picked up a set of 4 new folded dipoles that look like those at
Dayton one year and they had a Celwave tag on them.

Verision, in the Dallas, Texas area, recently sold their interest in BPL to
"Oncor", Which was part of TXU before it was split apart, who is the local
power Billng and Powerline company for several million/billion, I don't
remember the exact mononatary number, like it really matters anyway!.
