Unfortunately, detailed explanations of how this was done have been purged from forums and groups
along with any valid license keys because usoft sifts through the internet to kill any mention.

If you have an activated installation with updates and software you want to keep, you can image that and
have a recovery back to where you won't have to screw around with much to get back to normal if all that
crashed was a hard drive and the machine is the same.

Many XP OEMs had a hidden recovery partion that could be activated either by a recovery boot disk or from
running a utility if you could boot up.? This would give you a fresh "out of the box" installation all pre-activated
(but requiring updates).? Using wrong versions of imaging software or incorrectly is likely to wipe out this
feature leaving you without a valid license.?

What you describe is the "bare-metal" solution, that recovers an image that is custom built, mostly virgin in its
registry, and has a variety of drivers that will install minimally, at the first run.? This gives you a mostly clean install,
and will only work if the activation conditions are met (part of the build).? If activation fails, you can trick it to give
you a grace period, but after that you can't get things to work and can't fix it without ratting yourself out to usoft.?
I don't know if it works anymore with XP since it's no longer supported.

DOS, win9x and 2000 don't require activation.? Just have a good key.? Never put your good key on the internet
or it will go dead.

1 dB less than that is typically what I get out of a MASTR II or MVP, which has the same spec. However, at least here in SoCal that's pretty much equal to the noise floor on 2 meters. Depending on the site I may or may not try adding a preamp; in most cases no because the actual S/N improvement is insignificant. However at 0.4 uV that's 2 dB worse, which in most cases would clearly be throwing away S/N. So I wouldn't be happy with 0.4 uV either - worth getting that 1 dB or (hopefully) more back.

I strongly disagree Scott... That's a recipe for disaster. Feeding wide band unsquelched noise to a modulator will cause the transmitter to over deviate. Remember the squelch noise out of a discriminator is half the bandwidth of the IF filter which means you have audio at 7.5 khz + coming out of the receiver.. Anytime I run flat audio, I always put a clipper/limiter circuit in line to prevent over deviation, and also to limit the audio bandwidth to 3 kilohertz maximum. Under FCC part 97 rules we are required to make sure that we use good engineering practices. Running raw discriminator audio straight into a transmitter modulator without any processing violates that rule. I've done that in microwave systems but that's a special case and you have the bandwidth to do it. In the crowded VHF/UHF bands, it's totally ludicrous to do so

The MTR is reading 0.4uV (115 dBm) at 12DB SINAD. I’ve aligned the repeater 3 times now and even tried directly to the port on the receiver module. I must be doing something wrong, my UHF MTRs are much more sensitive.

I need to take a VHF MaxTrac I have and test it’s 12DB SINAD by itself and then through the duplexer and see how it goes. I’m sure I’m chasing a ghost and really have a receiver issue.

Taxing the brain, With XP, one had to mod the registry to go back to the bios for

the disk driver if the motherboard IDE or SATA driver changes. Then at first boot

on the new hardware, it will install the appropriate hard disk driver and video drivers.

So last night, I measured the MTR at 0.4uV at the receiver port and 0.5uV at the duplexer antenna port.

I injected a signal into the receiver port of the MTR that had just barely had no noise and when I injected it through the duplexer into the repeater, there was noise present. It wasn't heavy noise but it still had noise on the signal.

Hello Jared,

I have not been following these threads very carefully, but the thought occurred to me wondering if your transmitter might have spurs when connected to the duplexer? It would be easy enough to check with a spectrum analyzer connected via a lossy T between the TX and duplexer, (if not already checked.)? I had just finished working on a Spectrum repeater that did have spurs close to the TX frequency, corrected by retuning each stage while watching the spur level drop until they disappeared.
