The original complaint was running out of tunning range on the piston trimmer in the channel element while trying to net the crystal on frequency. Not rubbering the crystal to another channel or Nuclear warfare on an inactive club. Also I should mention that the receiver should be set by looking at the LO frequency on either a service monitor or a frequency counter of known precision, Tuning it until it sounds best is not the way to go. The LO frequency for the MASTR-II VHF will be either + or - 11.2 MHz from the receive frequency depending on the whether high side injection was specified when ordering the crystal.

Maybe you just got lucky on the RX element, but 9 times out of 10, I've had to change caps in Micor elements to get them to net, regardless of whether the crystal came from Bomar, ICM, or West Crystal. --- Jeff WN3A

[Repeater-Builder] Re: Bend an ICOM a little further
I just got some Bomar crystals (Not my choice) for the clubs UHF Micor I just got some crystals from Bomar, my first crystal order in about 40 years. Some were basic crystals for an Alert Monitor receiver and some were in channel elements supplied and compensated by Bomar. Every crystal/element that I received was right on the money and one of the elements didn't even require a slight touch up to hit it's mark (my frequency reference is a bit more accurate than the average service monitor, too). AND,some of this equipment operates in the temperature extremes that have been prevalent in the midwest in recent weeks. My suggestion would be to avoid implicating a manufacturer for an individual case of error as there are far too many variables involved to pin the results on any one cause. I have no business involvement with Bomar, just a satisfied customer. My only gripe is their minimum order requirement which means that I have to wait to order until I can meet the requirement.

[Repeater-Builder] Re: DB224A new harness
Hello to all, This is just my opinion but since the new style harnesses have been installed on all of the new DB-224s, i have found that the patterns and recieve /transmit ranges have changed drastically for the worse I have replaced harnesses and also complete swap-out of some antennas and have found the ranges greatly reduced. i confirmed this by reinstalling the original antennas and or harness and quickly went back to the original performance ( it doesn't look good when a lightning dammaged 4-bay antenna outperforms a brand new 8-bay antenna). The harnesses were replaced because of lighting damages ( high SWR) but still had good rx . on the complete antenna replacements, i had actually swapped out DB-228s to improved the range for handhelds in the field but saw a reducedction in range for both bases, mobiles and handhelds. The new harnesses are using a stub tuning to make it easier for the non-technical people down in Mexico to put these antennas out the door quickly but only hinders the performanace of the antennas. my first time installing one of these stub tuned DB-228s caused me to send the antenna back to the ground 3 times , while arguing with the ground crew that They sent up the wrong section 1st( all eight bays should be in the same radiating plane not half up/half down) after numerous calls with DB Products about this with very little response, they said that the stub, change the timing of the rf wave using a a time diversity inversion to actually put all the bays in phase DELAY LINES , although half of them were inverted.. BULLL CRAP!! all it did was screw things up. the reason they did it this way, was to simplfy the building of the antennas. by grossly underpaid below the border non-technical labor. It is easier to tell or show someone to build all the antennas the same way and just invert one half of the antenna to make a DB-228 by putting together (2) DB-224s without having to completely build a seperate antenna with the bays oriented to match the other half. i have taken two of these new style DB-228s and reconfigutreed the bays on the lower half to match the upper half and you guessed it. the performance is back where it should be. As for the water ingress problem with DB-224/228 harnesses, i have always used Liquid Tape and Scotch 88 tape to seal all the connections and molded joints on these antennas ( I don't use Scotch-Kote as it eventually dries out, becomes brittle and disentigrates in the weather( it is fine for use in partially exposed enviroments, but just doesn't standup to the liquid tape for longivity, in the weather!!! I try not to leave anything to chance. Some people would say that this defeats the chance of recurring revenue, but i look at it this way, if i seal it up right the first time and never have to do maintenance on it, then that speaks well of my installation and i stand a better chance of getting more work from those customers than if i did a marginal job and had to keep returning to fix a recurring proplem for an unhappy customer, at my expense ! anyhow enough of my my ramblings for this episode. if you have time to play with a DB-228(new style, experiment with it and i think you will agree with me. if not, then MY BADDD!!

The Federal Law says only that is it illegal to divulge radio traffic to third parties or to use it for personal profit or gain (ambulance chasers), when I lived in Philadelphia in the 60’s the Phila PD used to pipe their communications into the various radio stations and TV Stations—then they passed a anti scanner law.

That's not true. Certain information (that which is specifically intended for rebroadcast to the public) MAY be rebroadcast. The statute (both Federal and State) has to do with privileged communications, not material which is intended for public consumption. It appears to me that this law is redundant. but then again most of the Gov't is redundant, so what else is new.

[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

So with that, aren't all the scanner sites illegal? Four points: 1) No station outside of Shortwave, TV, FM, or AM services are legally authorized to broadcast. 2) The Communications Act of 1934 and The Telecommunications Act of 1996 govern this. RF is the FCC's domains, unless someone really wants to rehash States Rights during this administration. 3) The use of the internet is governed by the FCC, through the divisions the telcos use, under the name they use: Common Carrier. 4) Interference with a common carrier is a FEDERAL offense, punishable by fine and/or jail time. On the point of #4, if a police officer pulls over a legally operated and authorized semi-trailer carrying a sealed load across state lines and tells the driver to break the seal on the trailer, that officer is interfering with interstate commerce and may be be arrested by the US Marshals. My advice? Don't test this law. If you do test this law and officers show up to arrest you, immediately call the US Marshals office. Oh -- get a good lawyer, and make him a rich man. And further -- it is impossible to broadcast over the internet or IP. There are mechanisms which work similar to the common-sense concept of broadcasting, but properly designed networks do not allow such packets to traverse the networks or the edges of the networks. Multicast, which is a broadcast like IP-based system has not been deployed on large scale basis by most providers. Like 99.999% of them. And they charge good money if your packets need to be in all places at one time -- that's X amount of bandwidth taken from ALL of thier pipes that service your points of interest. It's time for a repeal of that law, and a recall election to remove that member of the legislature from office. -- Kris Kirby, KE4AHR Disinformation Analyst

Have I asked some stupid questions? Yes, and no. For the former, you're in good company. The freezer idea isn't new; there's one repeater up somewhere in Canada that is near a rock peak mounted in a large freezer. It, along with the repeater trustees, were flown in with a helicopter. For your situation, it might be best to use a pair of freezers, and install a hasp and padlock on them. Put the batteries in one (or both) and the repeater in the other. If you can find self-resetting circuit breakers, I would use those for the batteries, and individually protect each battery from a common bus. This way, if you develop a shorted cell in one battery, or a dead-short across several or the battery itself, the problem becomes self-isolating. Of course, you have to be able to develop enough power from the other batteries to exceed the circuit breaker's trip rating. You'd be better off using fishing batteries than lawn garden batteries. Don't forget to make a gas collection/vent system using aquarium tubing or surgical tubing. Well, if you need a gas collection system, you don't have sealed lead acid (SLA) batteries, which means you're adding electrolyte or water a few times a year. SLA is the better way to go, but you have to watch the battery temperatures to prevent damage to the batteries during the warm months or when charging on a really good power day. Damage means the battery vents, and that's no good. So you need a good charge controller, and decent diversion load. I suppose if one was really inventive and handy with some metal tools, you could make a vertical rack and suspend a large weight from it. Then attach a screw/gear lift motor from the diversion system, and have a small, regulated generator from a different gear ratio making a few watts of power. 10,000 feet of wire-rope and an old oil well -- Kris Kirby, KE4AHR Disinformation Analyst

Consider this duplexer two very nice notches you can put in the standard VHF High Band range, each just not within a MHz or two of each other without more serious performance degradation. I've got more than one similar unit (I use these duplexers all the time) so maybe it's time to crank one down to see how low the resonators will go without physical modification. You could to all the notch networks in one path side to a specific frequency and separate the two sides of the duplexer or use them both for different tasks. There are many possible applications for these type of notch-pass duplexers. It's just that everyone wants narrow 600KHz offset packages for conventional ham repeater operation. But if you need to notch something out, it's hard to beat the deal or use it for a 152/159 commercial ham box. Another cute idea... separate the two paths within the duplexer for use on a separate tx/rx (dual) antenna repeater. The notch in the rx side (antenna lead/path) is tuned to the tx frequency and the converse for the other path. There are six very useful notch resonator networks in the box and they can be used in various combination for many things. s. skipp025 skipp...@... wrote: Re: VHF Decibel Duplexer I should probably buy this... or at least bid on it.
