Re: [Repeater-Builder] Re: Running DOS Programs on an XP or Vista (Windows) Computer.
I was making a similar flash drive based DOS to be able to use the DOS CT logging program on Field Day using modern laptops. When I ran the FDISK utility to partition the flash drive it also partitioned the hard drive in the computer I was using , effectively wiping out everything I had on the disk. So, be careful.

April 9, 2009 skipp025 at yahoo.com Hello Sailors, Let me share what I've found to be one of the more practical methods to operate some (not all) DOS Radio Programs on a Windows XP or Vista OS Computers. Please keep in mind there probably are a modest number of possible paths to reach a similar end result. Right now I don't want to burn a lot of time going into very minor detail. Please accept this overview as the method I used to receive predictable, useful end results. Notable requirements: 1 A computer capable of booting from a USB port, configured in bios as an external hard drive. The computer is configured to boot to the external USB flash/thumb drive as the first boot device. 2 A USB thumb drive, suggested size would be 2GB. I would caution against using really large capacity USB drives to avoid potential hardware conflicts I will not try to explain at this time. A utility was used to format (where required) and make the flash/thumb drive bootable in with DOS 5.0. Classic DOS Plain-Jane Autoexec.bat and Config.sys files were made and installed on the Flash (thumb)*. You must of course supply your own copy of DOS. DOS based Radio Software is pre-loaded onto the thumb drive. Don't expect normal operation from the computers floppy or CD-Rom while booted to the USB Flash Drive. I would hope but not expect the floppy drive to function. The computer is power on re-started (booted) to the flash/thumb drive. Radio software is opened, installed and or configured (paths and selected com ports). Test each of the installed software packages for proper operation. NOT ALL DOS RADIO SOFTWARE WORKS USING THIS method. The below DOS programs run on almost any PC that will boot from a DOS bootable flash drive. Mastr 2E and Mastr 3/3-P25 Control Shelf Mastr 2E/3/3-P25 MS Edit These DOS programs run from Virtual PC or DOS bootable flash drive. GEPCGE S825 SprectraMSF5000 MT1000 MPA SyntorX 9000 This DOS program will not run on all, but will run on many PC's that will boot from the flash drive. MT2000 These two programs will run only on an older PC, such as the Toshiba Satellite 110 with Windows 95. Midland XTR 8 CH Mobiles Midland SYN-Tech II Mobiles These DOS programs have been replaced with current – available Windows based programs. GE Orion Kenwood KingAstro MTS2000 DX Sprectra Engineering Below is a copy of the autoexec.bat file used on the flash drive. Although shown, the CD Rom drivers were not completely installed or tested.

I was not expecting the external flash drive solution to work as well as it looks. But of course I'm still sorting out glitches. I'll be happy to provide additional details as time allows.

Re: [Repeater-Builder] A desense issue
We had the exact same problem with a Glenayre on that same frequency at our 2 meter site a number of years ago. It turned out that the problem was wide band noise from the Glenayre. We had Wacom (shows how long ago it was) make us a cavity with a peak at 152.6 and a notch at our receive frequency of 146.16. Fortunately the engineer for the paging company was a ham and he installed the cavity in the Glenayre transmitter. It was like magic, we suddenly had our repeater back. This was the proof they needed to make a number of upgrades to the transmitter which eliminated the noise and it was able to operate without the cavity. The paging industry meltdown finally took care of the problem and the transmitter is no longer there. We have retuned the cavity and are presently using it on our APRS digi at the site. Jed Barton wrote: Hey guys, Alright, perhaps some of you have some ideas, cause this one has driven a bunch of us absolutely crazy. At one of my repeater sights, I have a 220 repeater, a 440, and a 900. Also, there is a paging transmitter about 3 feet away from all of this. Here's the issue. The paging transmitter is desensing both the 440 and the 900. The 440 repeater is a kenwood tkr850, and the 900 is an msf5000. I'm running a set of 4 cavity wacom cans on UHF, same for 900. The paging transmitter is transmitting on 152.6. We've watched it, and there is no doubt that the paging transmitter is the problem. The transmitter is a Glen Air. We can shoot a weak signal in to the UHF repeateror the 900 with the service monitor. That weak signal will get very strong as soon as the paging transmitter unkeys. We even went to the extreme of getting a filter from par electronics to knotch out the 152.6, but na, didn't work. As if this isn't bad enough, the antennas for the 900 and the 440 are only about 25 feet apart horizontally, it's as far apart as they can go. Any thoughts guys, anyone ever run in to this situation?

Re: [Repeater-Builder] OT- Digital TV converter box issues
Just bought a Phillips DVDR3576H, has an ATSC, NTSC, QAM tuner, records to hard drive or DVD and has built-in timers. Also has modulator for output to ch 3 as well as composite video, component video and HDMI.Also upconverts to 720i or 1080i. May be more than you are looking for, but it is reasonably priced and current production. Henry, K4HAL Nate Duehr wrote: Here's something interesting I noticed.

But, I haven't seen any DTV tuner boxes with clocks and/or scheduling capabilities to tune the correct channel prior to the recording device starting up. Has anyone else seen one of those?

Re: [Repeater-Builder] audio equalizers for repeater audio-circuit correct??
I just finished a remote receiver project where I had to de-emph using an RC circuit. I have always heard that the rule of thumb is: 75 us for wide band broadcast audio and 750 us for narrow band. I used a 3.3k resistor and a 0.22uf cap. 726us - close enough. It sounded pretty It sounded pretty good, so I thought, what the heck, I'll sweep it (it was raining). Big mistake. Now I don't understand why it sounds so good.Click here for the plot: http://webpages.charter.net/k4hal/de_emp.pdf Not anywhere near 6db per octave. The impedance out of the discriminator amp was pretty low, probably less than 100 ohms verified by loading it with resistance and the impedance of the audio input was high - about 500k. So, what is the correct time constant or corner freq for the circuit ? Henry, K4HAL -
Re: [Repeater-Builder] Digital linking project - Digital Sinad?
We use the same type of setup except we do not use internet linking. We simply use a seperate CTCSS tone for each remote receiver. The user can then select which receiver he wants to use by changing his CTCSS. Easy to do these days with most radios having over 100 memories. The users do not have any trouble with it once they get used to it. We call it manual voting. Henry, K4HAL __ Do you Yahoo!? Yahoo!

After many years, the final on our UHF Micor repeater (not a converted mobile) has burned up. Naturally I dont have a manual. The amp is a TLE1713 and the toasted board is a TLE8333A.
