Re: BTECH AMP-220 Amplifier
Well, curiosity got the better of me, so I went out and bought one of these to see what was inside. Honestly, I'm disappointed.? The construction is good enough for a $100 amp, but performance is off. The transistor is a Mitsubishi RD35HUP2, A 35 watt single MOSFET amp.? I believe it's bigger brother, the RD70HUP2 is used in some Yaesu VHF radios. One drawback is that it does not appear to have a place to connect PTT. From what I can tell, it appears to only have RF sense. If anyone has questions or would like to see additional pictures, let me know. ?

Re: Kenwood TK-7302 input audio pin 5
I believe pin 5 is not pre-emphasized. It is marked ¡°DI¡± which on other Kenwood's of mine *has* been sufficient for mmdvm/9600 baud, so you might be OK.?

Re: Kenwood KPG89D serial number
Call your local Kenwood dealer and purchase the software - or reach out to one of the several on this list and buy it from them. Pretty sure asking for software on this list is not allowed and asking for a serial number is just as bad. Dan Woodie, CETsr KC8ZUM? On Thu, Nov 3, 2022, 8:05 PM Brian Horst <k5in@...> wrote:

Re: Somewhat OT... imaging a hard drive...
¿ªÔÆÌåÓýMike:I may have misunderstood your request but here is a possible solution. I have not read through all of the emails, but of those that I have read, I have not seen a mention of "Casper" (Get it?).? It if has been mentioned, I apologize for taking this space. Casper is by Future Systems:? I have used it for years to make full bootable copies of my OS and also identical copies of a RAID-1 Data Drive I use in all of my desktop computers. I typically do this once a week. I prefer bootable copies to an image since you have to restore an image to make sure everything worked. I can test any of these clones by substituting it for the boot drive. If I lose the OS drive, I can take the backup copy and simply replace the OS drive with it and everything is restored to the point of the last backup copy.? I can get any differential off Carbonite and add it to the clone. I also made copies of a boot drive of a Dell 755 and plug it into another Dell 755 and it will boot, etc. with all the drivers, but I recall that it will eventually ask for new Product Keys for the various softwares on the new OS disk.? But this is never a problem when you put it back in the very same computer. I use Casper version 8.0.4612.? There are later versions, but this one still works fine.? They had a runtime version on a CD called Casper XP that you could boot to and restore the OS drive from a backup. They no longer offer this. I think the runtime license to Microsoft ran out. But it would be superflous for me since I typically use an identical size drive for the clone. The few times I have had an OS Drive problem, I take the backup clone to another computer and make a backup there to plug back into the problem computer. I don't want to lose two drives if it is a hardware problem. I leapfrog the clones so that I have clones for the past three backups in a fire resistant box under the desk. I occasionally take one home for safekeeping.? This multiple disk system is all purely driven by paranoia from having a hard drive fail right in the middle of a project due within a day or so. It happened the first time, but each time after that, I had the document on a RAID-1 drive set.? If it was the OS disk, I take the document off the RAID-1 and go to a new machine. I keep an identical machine in my library. If you have it on a computer and you also have two USB ports, you can take a OS drive out of a another computer and make a copy of it on the first computer from disk to disk and plug the OS drive or copy back into the computer you took it from and both will work.? This would be if you can otherwise make a clone of the drive you want by installing Casper on that computer. The only problem I had with Casper was that I had Carbonite running on my main computer. It was accessing the OS drive at the same time as Casper.? Too many errors and Casper will stop.? I pause Carbonite for the time that it takes to make a backup and that problem went away.? Casper has a "smart clone" option which evaluates what files are already on the drive that you are copying too.? It only duplicates the new files that have been added and rearrange other files to duplicate the originating drive.? This means that it usually only takes 20 - 30 minutes to "catch up" the 1 Tb OS copy from three weeks ago.? My 4 Tb data drive that the first time might 14 - 18 hours or longer to duplicate might take 40 - 50 minutes to add new data to three week old clone depending upon how much I add. I hope this is helpful. Micheal Salem On 10/30/2022 4:14 AM, M M wrote:

to make the quote feature do what I want.? If only there was a referrence and a spell checker... "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.
Can anybody remember the details?

Re: Somewhat OT... imaging a hard drive...

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. |

Re: VHF MTR2000 Poor Receive Performance
It certainly is worth getting the receiver back to where it belongs. I¡¯m not going to take the time and drive to the site and install everything just for it to continue to be deaf and run like garbage.
The previous owner of the service monitor said the level was accurate to the dial but was 1khz low. But I still use my spectrum analyzer and make sure it¡¯s on frequency and the level is correct. I know it¡¯s a Rigol but it¡¯s better than anything. I don¡¯t know if the receiver is on frequency, I guess I should figure out how to do that. |

Re: Windows 7 config
I have to agree with Chris on this.? Running raw discriminator audio directly into the modulator is going to cause problems.? You need "something" ahead of the modulator to control the maximum deviation.? This is one of the reasons I disagree with the idea of coming out of the discriminator, going directly into the modulator and setting the system for 5 kHz in and 5 kHz out.

Years ago when I was on the TASMA technical committee one of the most frustrating problems I regularly faced was with people who would do this.? In a lot of cases the squelch tail was measured going out to 20 or more kHz of deviation, while popcorn and noise from signals that were only partially quieting went out to almost the same.? They don't understand.? It's just bad practice. Burt, K6OQK On Tue, Nov 1, 2022 at 10:29 AM, Chris Boone wrote:

Spec for the MTR2000 VHF is 0.35 uv or -116 dbm at 12db SINAD, so his receiver is pretty close.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. Bob NO6B |
