[Repeater-Builder] Re: DB224-JJ Dimensions Wanted
Our G7 is 1/2 wave from the tower (about 24). That seemed to work best for us. The tower is guyed with a 19 face. Think it's a Rohn, but that is of no concern. So far I am pleased with it's performance, just looking to optimize coverage as much as possible w/o remote receivers. Right now getting about 80% of the coverage we would like. If I can get to 90-95% I would be happy. To be honest, I want 110% coverage(who doesn't! HiHi)!! As far as the dimensions of the elements, I have them at home, I will send them out later on. Thanks all!!

They are becoming hard to find, even from manufacturers. I would also consider a Hustler HD6-5 or something similar to that. If someone has the dimensions for the 224-JJ Loops and maybe the spacing distance... I think I can get them made. A local (to me) Ham has made a metal forming jig for loop antenna materials and is currently cranking out 440 loop antennas like crazy. I could get him to re-size the jig and crank out some 224 MHz loops with their mounts. Anyone have the JJ info available? I'm currently using a Hustler G7-220 side mounted, which works OK, but looking for something that could be top mounted. I've got a G7-220 Tower Top Mounted and it works killer (good). Having problems getting coverage in the areas I need due to shadowing from the tower. Any help or suggestions would be greatly appreciated! Changing the spacing of the antenna to the tower would modify the pattern. s.

RE: [Repeater-Builder] FS: *NEW* UHF Motorola Micor repeater on Ham band
Eric I was just relaying what I was told (by a gov radio tech) about how the repeater handels encrypted communications. It just passes audio straight through be it encrypted or analog. That way someone at the repeater site can not eavesdrop on the secure communications going through the repeater. At least that is the way it was explained to me and that is how I understood it. The extra cards and such just handle keying functions and encoding I believe. In analog mode, yes, it works like a regular analog repeater. In DVP mode, it regenerates the received data stream so that noisy input signals aren't re-transmitted as-is, it's clean, re-clocked data that goes back out the transmitter. Micor DVP receivers (at least on UHF, haven't tinkered with VHF) have different IF filtering to provide lower distortion for better recovery of DVP. Standard Micor receivers don't work well with DVP. IIRC, the DVP exciters have the flat audio board akin to what was also used in Micor/PURC paging stations. WA9ZZU probably has details on this. A local club picked up two real-deal M split 142-150 MHz Micor stations, brand new, from military surplus a few years ago, possibly from the same place this UHF station came from. Maybe there's a whole stash of ham-band Micors sitting in a government warehouse somewhere. Maybe Area 51? --- Jeff WN3A

RE: [Repeater-Builder] Was Repeater Battery Question
The site I maintain isn't solar powered but I did add battery backup two years ago and it's been working very well. Batteries are Interstate SRM29's charged by a Samlex SEC-2415 auto charger. The loads are powered thru a Samlex ST1500-124 pure sine wave inverter with a built in transfer switch. I find the switch to be bumpless and the inverter's output is quite sinusoidal. Batteries were $95 each delivered.

Re: [Repeater-Builder] Was Repeater Battery Question
I'm using a pair of Deka GC-15 in series. I passed on the Sams, Interstate, Autozone, TSC, etc. batteries when I found many were manufactured out of country. There are definitely different levels of performance in deep-cycle batteries. Note the difference between deep-cycle and starting batteries. Talk with your local golf cart dealer to find out what he recommends. Also we have a local auto battery/alternator specialty shop that had good advice. I found out why I had been having poor battery life with the bargain batteries I purchased. Trojan batteries also have good performance. My local golf cart guy had warranty problems with them and stopped using them for a while, but is now stocking them again. Look up the prospective battery on the Internet. For a deep-cycle battery with a bunny name on it, I eventually found that it just carried the brand name. The brand's web site didn't even acknowledge the part number. It turned out to be manufactured by a company in Mexico. Google is your friend. Also look at solar power and electric automobile sites for user-reported problems. Consider an automatic low voltage disconnect to prevent your battery from being discharged too much. rrath wrote: Well, I did not receive any replies to my question.
