Re: [Repeater-Builder] Good Radio's for Repeater?
In the case of the MastrII,its the 100% duty heatsink and the extra shielding and control offered by the repeater package that makes all the difference in the world. I have a MastrII UHF porta-peater which really works well in the mobile chassis.73,Lee Robin Midgett wrote: I've been following this thread with interest, and have a couple of points which (of course) lead to more questions. The MASTRII RF strips are the same in the repeater chassis and the mobile rigs, band for band from low band to UHF. Flexibility and convenience options (and continuous duty PA issues) aside, why is a MII repeater station better used as a repeater than a MII mobile rig? I don't know if a Micor mobile and Micor repeater use the same RF strips or not..do they? If so, then the same question applies, with the same qualifiers. Same answer? Granted, a reliable repeater is not made from a pair of whatever you can scrounge mobile rigs with a controller in the middle. (Maxar comes to mind as something in that category). Also in that line up are amateur radios with 20% duty cycle, or practically anything that says Alinco on it. Where reliability concerns are fewer and convenience issues are greater, then latitude is greater and mobile radios with a controller in the middle (port-a-peaters) become attractive. Thoughts?

Re: [Repeater-Builder] back-up battery charging
Well,what I came up with is since the Micor supplies arent adjustable,was two silicon diodes in the charging circuit. Drops it to 13.5v then added a contactor,normally closed,with a 125vac coil to connect direct to the batteries during an outage. I will post the results once implemented. 73,Lee Eric Lemmon wrote: There is a simple way to have a reliable backup battery system without a relay. Try this: Connect your fused repeater power cable directly to the battery terminals, without any intervening devices. Connect your power supply to the battery through a single Schottky diode. Adjust the power supply voltage so that the battery is floated at its optimum voltage, to account for the small forward voltage drop across the Schottky diode. I use a Schottky diode because its forward voltage drop under load is much smaller than that of a silicon diode and is stable. The diode is needed because some power supplies have a tendency to go into a crowbar shutdown mode if the AC input goes away (as during a power failure) while a DC voltage is maintained at its output by a battery. Such an event will blow fuses and will almost certainly shut down the repeater. Unless the repeater operates almost continuously, the power supply does not need to match the current draw of the radio during transmit. I have a 50 watt base station set up this way that has a 26 Ah VRSLA battery floated by an Astron RS-10 power supply, and it has been 100% reliable through many power outages. I used an International Rectifier #122NQ030R diode, simply because it was easy to mount on a copper bar that is bolted to the positive terminal of the power supply. The R in the part number indicates reverse polarity, meaning that the diode terminal screw is the cathode, which is convenient for attaching the load wire. Here's the datasheet: http://www.irf.com/product-info/datasheets/data/122nq030.pdf 73, Eric Lemmon WB6FLY Yahoo!

While checking the pigtail I made up for the antenna, I discovered that I didn't have any measurable continuity between the center conductor inside the radome to the center of the S0239, however I have 0 ohms between the center element in the radome to the outside of the S0239, i.e. ground. There is a matching coil in the area of the radials. I am presuming that the center of the S0239 is probably connected to the center element through a capacitive coupling. For clarity, I brought out the second antenna and checked it without the pigtail and get the same readings. I am sure the antenna is OK, but would like to understand how the center of the antenna is coupled to the center of the S0239. The larger 9/11 dB version I bought at Dayton does not have any measurable continuity between the center and ground, so I presume it is the same design, just larger in size for gain.

I need to know the role of the two stages, the first being the M9690 and the second stage being the pair of M9737's. What I want to understand is what kind of output should I expect and which is the tripling stage? i.e., does the signal get tripled in the M9690 and then the output power boosted in the second stage (two M9737's) or vice versa. I really don't know. I find zero literature on the web. Any help anyone in the group can provide will be greatly appreciated. thp Your use of Yahoo! Groups is subject to the Yahoo! Terms of Service.
Re: [Repeater-Builder] UHF Micor Tripler
It doesnt sound like the 557 is even close. Mayhaps someone on the list has a 9690? Micor mobiles are cheap enough to have lots of spares around. Yes,the wider lead should be the collector. If you are converting to ham band from commercial you should read about the circulator mods on the website. Beyond that, I cant help much. 73,Lee,N3APP - Original Message - From: Tom Parker To: Repeater-Builder@yahoogroups.com Sent: Sunday, November 30, 2003 7:23 PM Subject: Re: [Repeater-Builder] UHF Micor Tripler Ah Hem... uh.. thanks Lee, but I've been there. Here's the deal, the MRF 557 does not directly replace the M9690, i.e., the 9690 is stud mounted and the MRF 557 has no stud and one lead wider than the others, but there is no clear estimation of where the wider or what the wider lead is, I would assume it's the collector, but not being totally sure, I thought there might be some experience out there that could help.. In the absence of any data sheet or other information, I cannot 100% determine that mine is out, i.e, the signal appears to be tripled at thit point, but the power is greatly diminished instead of amplified (the MRF557 is rated at 2 watts and has 6 or so dB of gain (if I remember correctly). I really would like to know what's going on before I tear one of these puppies apart and get totally lost because of my misguidedness. Thanks for the reply though,thp Your use of Yahoo!

Re: [[Repeater-Builder] Spectrum Communication SCR1000 VHF Manual]]
I think its a combination of inferior components and poor design. The receiver is quite sensitive,but not very selective and overloads easily. You would be better off dropping some GE or /\/\ boards in it. 73,Lee - Original Message - From: ac0y5 [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, November 26, 2003 8:43 PM Subject: [Re: [[Repeater-Builder] Spectrum Communication SCR1000 VHF Manual]] : It seems a lot of the complaints are from oscillator drift and : tuning drift.

Re: [Repeater-Builder] Identify an high Split master Pa ??
The two blue pots are for setting the power control protection circuit and needs to be tuned to the procedure in the manual. If this is a continuous duty pa,it has two air variable capacitors on the tuneable output filter which also should be tuned according to the book. Mis-adjusting them will cause problems. A manual is a must-have ! 73,Lee,N3APP - Original Message - From: gervais,ve2ckn To: Repeater-Builder@yahoogroups.com Sent: Tuesday, November 25, 2003 8:00 PM Subject: [Repeater-Builder] Identify an high Split master Pa ?? hi, i install a pa on a Master 2 repeater Low Split Vhf of 105 watts output, i have try to balance de pa and when we begin to tune the 2 potentiometer for the matching of impedance of the natenna we hear a tone FROM the transmit audio of the Master 2.

Re: [Repeater-Builder] Kenwood TKR-820 is microphonic
You might try the old trick of encasing the microphonic circuit in wax. Candle wax works and can be removed easily if repairs are needed. You can use a piece of masking tape to form a dam around the desired components. Use clear or uncolored wax. 73,Lee,N3APP - Original Message - From: Bob Lott To: Repeater-Builder@yahoogroups.com Sent: Saturday, November 08, 2003 11:31 PM Subject: Re: [Repeater-Builder] Kenwood TKR-820 is microphonic We have 10 of these in service in my area, 8 out of 10 do the exact same thing, the "ECHO EFFECT", That is what I call it. They are great radio's and make excellent UHF repeaters. I have found that removing the internal speaker jumper from the back plug helps and also making sure that the volume knob on the front panel is turned all the way down before I leave the site seems cures this problem. Bob Lott "K7SOB" [EMAIL PROTECTED] "Derek B. McIntyre" [EMAIL PROTECTED] wrote: Hello Group,Recently installed a Kenwood TKR-820 on the ham band for a local repeater. Went through the service alignment and all checks well. Aligned both TX and RX VCO's and noticed while the transmitter is keyed, lightly tapping on any component in the TX/RX section modulates the carrier. Didn't think much about this until we did the install. The repeater sits on a shelf in a television station transmitter room. The blowers and HVAC equipment in the room are rather loud. When I got back home, I keyed the repeater and noticed a continuous microphonic hum on the repeater carrier, obviously coming from the vibrations in the transmitter room. The "hum" isn't bothering anything. It's just barely there.I have noticed other TKR's doing this, some worse than others. Is there a common problem associated with these, and if so, is there a common fix? Thanks, Derek KC4FWChttp://www.w4dex.com/kc4fwc/00.htm Your use of Yahoo! Groups is subject to the Yahoo!
