Re: [Repeater-Builder] Low voltage disconnect in Alberta winters and more
Tony, What's to back up at a site already supported by both solar and wind? Is there a temp below which the PV panels won't produce or the wind turbine won't turn? Deep snow covering the PV panels? I guess my preference, for a number of reasons, would be to have a way to remotely invoke an operating mode for the repeater which could dramatically reduce standby current drain and/or transmitter power when the batteries were detected to be at any risk, or just massively bulk up on battery capacity. I had a solar powered UHF repeater in Florida once that used a 2-watt Repco RFID transmitter strip and companion receiver. Total current drain while repeating was about 700 mA. A standard 100 AH deep-cycle battery represented four days' reserve at 100% duty cycle. That would be expensive to replicate with normal repeater power levels, but maybe not as expensive as some less robust alternatives. If the PV panels get covered with snow, could you rig an automotive windshield wiper system to fire once an hour during snowstorms to keep them clear? If it's -40º, would the snow be dry and light enough to clear with a periodic blast from a cordless leaf-blower motor? The decent ones use 18-volt battery packs, but a small DC-to-DC converter could keep it charged, or switch two small 12V aux batteries charged off the main system into series, and run them through a dropping resistor to protect the motor. You'd only be running it for a few seconds at a time to keep the panels clear. What's the ground like? Could you dig deep enough to bury a battery storage locker below the frost line? Cave effect is a cheap battery temp regulator! If you're going to store fossil fuel at the site for use in protecting the batteries from freezing, what about just heating the batteries to keep them above 0ºC, and forget the moving parts involved in a generator scheme? Internal combustion engine generators are notorious for having starting problems when needed, because they sit much of the time. Interesting project and questions! 73, Paul, AE4KR - Original Message - From: Tony VE6MVP To: Repeater-Builder@yahoogroups.com Sent: Thursday, February 18, 2010 10:16 PM Subject: [Repeater-Builder] Low voltage disconnect in Alberta winters and more Folks I've been reading the low voltage disconnect thread with a great deal of interest. Thanks for the tips and suggestions. We're putting up a VHF repeater and two UHF link radios on a solar/wind power site.Given Alberta winters what would you folks suggest as a low voltage disconnect value to avoid the batteries freezing in winter? Which can hit -40 for a few days. Also we're thinking of having a backup power generator being a lawn mower motor hooked up to an auto style alternator and a rioughly eight or ten hour fuel tank.If the batteries get too low then we'll just attempt to get into the site, fire up that home made generator and walk away. We'll make sure it looks like a rusty piece of garbage so no one who wanders by is likely to steal it. Any comments? (Apparently the snow drifts can get quite bad so we might need to borrow a snowmobile for the last 400 yards or so.) We're thinking of putting the batteries in a chest freezer disguised by thin plywood so it just looks like a box. We're told by the site owner that a fridge looks way too much like trailer trash so disguising it with wood should work.I'm thinking we would put the charge controller in there for a little heat and the dump load in winter Are we nutz? Have I asked some stupid questions? Tony

I contacted customer support and told them I had 3 fairly new DB224's (2 a models and a b model) that had water intrusion/contamina tion in the harness where they were supposedly seal by the factory. I offered pictures and they accepted. Upon seeing the photos they asked that I give them serial numbers and requested I send the defective harnesses to them. I did and they offered and I accepted replacement harnesses. The two db224's that I have (personally) are the A models. The B model belongs to my shop. I often end up with abandoned and or defective db224's and other antennas as I work for a two way land mobile dealer/shop.

If you look at the attached photoes from my initial post, you will see that the open 25 VB-8 (50 ohm) stub is 12.5 from the T where the top half and bottom halves of the harness come together, down the main feed to the hardline (or whatever you feed the antenna with). Last night I connected the Sitemaster up again and I noticed the the SWR will come down some when I firmly secure the harness to the mast with the metal tape. How far down remains to be seen.

Sounds like a T match L-C-L tuner. The advantage would be that it is a low-pass tuner that attenuates harmonics. This was important in the old days when rigs put out harmonics.

RE: [Repeater-Builder] manual and service manual scanning (digitize to PDF)
Benjamin, There is no need to mosaic anything. The key is to use a commercial scanner that has a throat of at least 48, so that long foldout sheets can be scanned in one pass directly into PDF. Such machines are very expensive, and would normally be found only at a commercial graphics house. It is not a good idea to scan long pages into segments that later must be taped or somehow pieced together. Mention has been made of stitching the pieces back together using special software, but this is unnecessary if the original had been scanned in one piece. Besides, I have never found such software to be either 100% effective or reasonably priced. The free Adobe Reader package includes a great feature, called the SnapShot Tool. Depending upon the Reader version, this may appear on the toolbar as a camera inside of a box, or it may be in the Tools drop-down menu. If all you want is a portion of a long foldout schematic, simply select that portion with the SnapShot Tool cursor, and it will be copied to your Clipboard. You can then print out that detail on a standard page printer. Another issue is that a line drawing, such as a schematic diagram, should be scanned directly into PDF to maintain high quality and a reasonable size. Image formats such as GIF, TIFF, and JPEG are great for color pictures but are not appropriate for line drawings. When an image has but two bits, either 0 or 1, it is a huge waste of file space to scan it as if it had 16,000,000 colors. Adobe Acrobat Professional software includes drivers that seamlessly interface with commercial scanners. When scanning pages directly into PDF, use the line drawing setting unless the 8-bit gray scale setting is needed for photographs or PCB layouts. Above all, do not scan any black-and-white images as color images. Finally, all pages should be oriented as 11 inches high, regardless of viewing aspect. This will permit the PDF to be printed on a commercial roll printer, reproducing the original in exactly the same size and format as the hard copy that was scanned. Unless every page of a manual is 8.5 by 11 inches, take it to a commercial graphics house for a professional scanning job. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Benjamin L.

Re: [Repeater-Builder] Duplexers F S
Oddly enough, that's my ad ;) Thanks for the bump. The 4 WaCom UHF 10 cavities I believe were designed to be part of a simple duplexer for a UHF-Lo repeater. They *should* tune up to the 440 ham band based on what Telewave has listed for specs on the current modern day model number. Current config is Pass RX Reject TX on 3 cans and Pass TX Reject RX on the 4th can. I would be more than happy to email out specific high res pics to anyone directly off list. 73, AJ On Fri, Feb 19, 2010 at 7:44 PM, motarolla_doctor echoco...@hotmail.comwrote: I ran across this... http://batboard.batlabs.com/viewtopic.php?f=2t=89919

Re: [Repeater-Builder] DB224A new harness
Hello Allan As you note it would take a good deal of work to go from 154 to 220Mhz. Yes the loops would have to be shortened and the harness would have to be be reworked-shortened. This would be easier than changing to 144Mhz. I have done this twice in the past. 73 de Tom Manning - Original Message - From: allan crites To: Repeater-Builder@yahoogroups.com Sent: Thursday, February 18, 2010 5:47 PM Subject: Re: [Repeater-Builder] DB224A new harness Tom I would certainly be interested in knowing just how a 150-162 MHz DB224 could be easily be modified to cover 220.

I often end up with abandoned and or defective db224's and other antennas as I work for a two way land mobile dealer/shop. Unfortunately, I have yet to get any DB224e's or any DB304's, just tons of DB224a's and an occasional DB224b. Hats off to Andrew for shipping me free replacement harnesses. I am still gonna ScotchKote those moldings regaurdelss. If you look at the attached photoes from my initial post, you will see that the open 25 VB-8 (50 ohm) stub is 12.5 from the T where the top half and bottom halves of the harness come together, down the main feed to the hardline (or whatever you feed the antenna with). Last night I connected the Sitemaster up again and I noticed the the SWR will come down some when I firmly secure the harness to the mast with the metal tape. How far down remains to be seen. I will keep you posted. 73 and thanks! de N5NPO Norm
Re: [Repeater-Builder] DB224A new harness
Tom, Perhaps you could enlighten everyone who read these discussions with your success in modifying a DB224 from the 150-162 range to the 220-225 range. You are the first I have ever heard of having done this. I know I would be particularly interested in the harness transmission lines used and their lengths, and their characteristic impedance's. I would also be interested in the impedance measurements made of the dipole configuration after being modified, how you determined the appropriate coax transformation impedance's, and how you compensated for the positive and negative reactances which appear as the freq. is varied from the center freq. to the band edges in each transformation. Would you also include the instrumentation used for your designs? If you employed the use of a Smith Chart in your calculations can you provide a copy showing the impedance response curve vs. freq. for the range 220-225 MHz or whatever you measured? There are no loops on a DB224, only folded dipoles. Loops are circular, dipoles are linear.
