Excellent for clearing crud out of hijacked browsers. I keep a copy in my virus removal toolkit - and the copy is named iexplore.exe so that the malware that does filename checks lets it run (like some blackmail-ware). Add Mike Lin's Startup Control (the single file exe version, not the installed version) as it helps resolve issues with programs that start when the system starts up. I have all my antivirus tools on a SD card that is in a USB flash drive reader. Why an SD card? Because the card has a write protect switch. Load the card, flip the switch, and it can't be written to like a regular flash drive can. Other than write protection I treat it just like any other flash drive. See http://www.allelectronics.com/make-a-store/item/SDR-1/SD-CARD-READER/WRITER-USB-2.0/1.html The reader costs $4. A 4gb card is under $20. Naturally larger cards are more expensive. The SD card and matching reader is cheap protection for the antivirus / malware remover part your computer toolkit. The only complaint I have is that the All Electronics reader is a bit fat and blocks the adjacent USB jack on some systems. A 3 inch USB extension cord fixes that. Lastly - never use a flash drive / thumb drive / pen drive as your permanent storage - only as a secondary or transit storage device. I've seen too many die with no notice, and be irrecoverable.

Both my 16bg regular toolkit and my 4gb antivirus toolkit have a backup copy as a folder on a raid-protected server and as a folder on my laptop.

Re: [Repeater-Builder] Silver Plating - Cheap Easy
It's actually used photographic FIXER that contains a lot of free silver... the fixer removes any unexposed silver in the film emulsion. For many years I recovered the silver from my fixer by adding powdered zinc, which will dissolve more easily in the solution than silver will, causing the silver to precipitate out. Collected over 28 ounces over the years. His method of silver plating probably involved connecting the negative lead of a low-voltage source to the can, filling it with used fixer, and then suspending a zinc electrode in the solution, connected to the positive lead. The zinc goes into solution, and the silver, instead of precipitating out, plates out onto the can. If the fixer is sufficiently loaded with silver (exhausted, in photo-speak), it will plate out on copper without any current source, but adding the batteries will speed things up result in a thicker layer of silver.

The comment period for the NPRM ends July 7. If you have not already filed comments in opposition to this radical re-write of Part 95, which would essentially turn the GMRS into more channels for FRS possibly open those frequencies up to businesses, PLEASE do so immediately!!! The most effective comments are those written in your own language, and citing your experiences with GMRS that make these rule changes unacceptable, i.e., the limits of simplex operation therefore, the need to retain repeaters in GMRS, particularly for public service/emergency use; the behavior of children young teens on FRS and unlicensed GMRS use that makes the elimination of the age requirement untenable; the need for licensing to keep voluntary coordination interference resolution possible, as well as to retain the professionalism that currently exists among licensed users, etc. Even if you're NOT a GMRS licensee, PLEASE help us defeat this!!!

the amplifier is class AB and is 8 mosfet transistors beautifuly engeneered to split and combine the power inside the amp...there are impedance balancing ciquits to keep the power properly distributed from the input amplfied and outputted to the duplexer or site combiner. now this amp runs far bellow it's capabilities just for the sake of the distortions that can occure from amplfying...moreover there is error ellimminating computer for the input signal just for the sake of linearity and error and distortion free output from this beast! yo know that this is important for digital communication i am using it at it's power capabilities because is analog and does not matter the errors if the carrier that is carring my vice and the TPL. --- In Repeater-Builder@yahoogroups.com, Joe k1ike_m...@... wrote: Your saying that you took a 90 watt amp and modified it to 450 watts?

The amp you have is possibly a B band analog amp. 90 watts may have been used at the cell site to overcome the combining losses that are involved in putting multiple transmitters on a single cellular antenna. The ERP would probably have still been around 100 watts. You have to have a balance between the cell site transmit power and the cellphone transmit power to make the system work.

Hi George, You can but keep in mind the real world limitations of the small Flat Pack mobile style Duplexers. The VHF versions are not designed for Ham Radio repeater frequency spacings. You'd be hard pressed to get the more common surplus VHF Flat-Packs to play at 600KHz repeater offsets unless the Duplexer was originally designed for tight/narrow spacing. The typical UHF versions Flat-Packs can be specified for and operated with 3MHz and 5MHz spacings at honest modest power levels. A realistic person would not expect full Spectra Radio power levels (output) to play well with a flat pack. So that person would probably have to reduce/drop the transmit radio's (Tx) power to avoid desense issues. 15 honest watts through a flat pack is a generic realistic value, which also depends a lot on the quality (front end) of the receiver and the Duplexer. Of course your results will vary with cooking time... cheers, s.

The club is a general purpose ham club, not a repeater club, and does not seem to have any members who are in the 2-way radio business or have experience with commercial repeater site installations. They've had a 70cm FM repeater on this building for about 15 years. It has never had any form of lightning protection equipment protection equipment. The club has been lucky and not experienced any apparent problems from lightning. Within the last two years the club has replaced it's Icom 70cm FM repeater with a new commercial Motorola 70cm FM repeater. They've also added a D-STAR 70cm Digital Voice repeater, a D-STAR 23cm Digital Voice repeater and a D-STAR 23cm Digital Data Access Point. It's possible a 23cm FM repeater will also be added soon. There are three antennas on the roof currently for 70cm FM, 70cm D-STAR and 23cm D-STAR. A fouth antenna may be aded for 23cm FM. All antennas are fed with hardline ultimately terminated in N connectors at the repeaters. It is a very ham friendly site and we can do work on the repeaters the roof unsupervised. The only other repeater system on the building is a high-band U.S. government repeater adjacent to the ham repeater equipment rack. The government repeater seems to be grounded to a grounding bar running through the equipment room. These new repeaters antennas should have lightning protection. My question to the group is what form of lighning protection would you recommend for these repeaters. I assume Polyphaser equipment is one option, but we need recommendations of specific brands model #s of equipment with approximate prices if you have them. We plan to review any recommendations received then forward them to the club's board of directors for acquisition installation.

[Repeater-Builder] Fw: [DSTAR_DIGITAL] FCC Ruling on Repeater Definition
Federal Communications Commission Washington, D.C. 20554 March 23, 2009 DA 09-657 Mr. Gary R. Mitchell President, Northern California Packet Association P.O. Box K Sunnyvale, CA 94087 Re: Petition for Declaratory Ruling filed December 5, 2007 Dear Mr. Mitchell: This is in response to the petition for declaratory ruling that you filed on December 5, 2007, requesting that the Commission clarify the definition of a repeater in the amateur service rules. 1 A repeater in the amateur service is defined as [a]n amateur station that simultaneously retransmits the transmission of another amateur station on a different channel or channels. 2 You seek clarification of whether the word simultaneously in the definition refers to the signal information being retransmitted, or to the fact that the receiver and transmitter must both be active at the same time while acting on the same signal information. Section 97.205(b) of the Commission's Rules specifies the bands on which amateur repeater stations may operate. 3 You state that some amateur radio operators are operating on bands other than those set forth in Section 97.205(b) with systems that are essentially voice repeater stations, but that digitize and retransmit the user's voice, on the theory that because there is a small delay in retransmitting the signal of another amateur station, the signal is not simultaneously retransmitted and, therefore, the system is not a repeater. 4 Prior to 1994, a repeater was defined as [a]n amateur station that automatically retransmits the signals of other stations. 5 The Commission revised the definition in order to clarify that certain accommodations for message forwarding systems do not apply to other operating activities such as repeaters and auxiliary stations. 6 The Commission proposed to define a repeater as [a]n amateur station that instantaneously retransmits the transmission of another amateur station on a different channel or channels, but ultimately replaced instantaneously with simultaneously because commenters noted 2. that there is always a small propagation delay through a repeater. 7 As one commenter explained, The word `simultaneously' in this case means that the repeater is receiving and transmitting concurrently, whereas each signal might be slightly displaced in time between receive and transmit. 8 To be able to repeat another station's transmission, a repeater must be able to receive a transmission from another station and retransmit it. Because the word simultaneously in the definition is used to modify retransmit, we believe it refers to a repeater station's transmitter being active when retransmitting the signal received by the repeater station's receiver from another amateur station. We conclude, therefore, that simultaneously as used in the definition of a repeater refers to the receiver and transmitter both being active at the same time. Accordingly, IT IS ORDERED that, pursuant to Section 4(i) of the Communications Act of 1934, as amended, 47 U.S.C. § 154(i), and Section 1.2 of the Commission's Rules, 47 C.F.R. § 1.2, the Petition for Declaratory Ruling filed on December 5, 2007 by Gary R. Mitchell IS GRANTED to the extent indicated above. This action is taken under delegated authority pursuant to Sections 0.131 and 0.331 of the Commission's Rules, 47 C.F.R. §§ 0.131 and 0.331.

Each manufacturer selected what they wanted, light blue, dark blue, red, silver, bronze, etc. likewise, coil impedances were variable as well, from 500 to 5K ohms. if you have the stock number, usually beginning with an A0, I can probably tell you what you have. Decoders can be used as senders, however the drive is higher to get them to fire off reliably. note too that the Bramco reeds are position sensitive... especially below 100 hz...if you are going to use mechanical reeds for an application, try to get old Motorola gold reeds, TU217 sender and TU333 sponder, they were better in all aspects, especially sensitivity to close in the sponder reeds.

Re: [Repeater-Builder] Re: SCR-1000 crystals
Exactly the problem... so far, I have received copies of specs that say 30 pF, 12 pF, and 8 pF load capacitance sheesh...

Yep... and there are a few different varieties of oven type assemblies. They can have different load specs and even different (non standard) temp break points. If you're shooting in the dark trying to order crystals... good manufactures can take a very reasonable guess at the crystal specs if you can supply a basic osc circuit diagram. The trick is having the right diagram or drawing one up. oh joy... s.
[Repeater-Builder] Re: Scanning (was Re: Syntor X9000 Manuals)
That's how I've scanned the manuals I've uploaded... fortunately, I have access to a couple of Fujitsu flatbed scanners with document feeders that will handle the long pages, and in color, BW, or grayscale. (they are literally right outside my office door, in our medical records department) I'd be more than happy to scan anything for the list, for just the cost of sending the originals back.

But if I might ask a **TINY** little favor... IMHO, it would make viewing the board layouts MUCH easier if they could be done in color versus grey scale. Original Motorola layouts I'm familiar with used a two-color format -- reddish color for one layer and grey for the other -- but when the scan is done in grey scale, it becomes very difficult (at least for me) to sometimes follow the board tracings. However, if cost is the determining factor, I fully understand. OK, I'll go crawl off into my corner again. Hehehe 73 de Mark - N9WYS [snip]
[Repeater-Builder] SCR-1000 crystals
Our club has 2 Spectrum SCR-1000 2-meter repeaters (one from 1988 and one from the early 90's) which apparently have different crystal specs... I am trying to find out the board revisions numbers or exact dates of manufacture, but in the meantime, does anyone have the specs for the various revisions of the TX and RX???
