[Repeater-Builder] Re: Broken Rock MT. tower collapse
Look like the Aerial AV1312-1 air band dipole (118-136 MHz) to me. http://www.aerial.fi/ep/tiedostot/aerial_vhf.pdf regards, ---per --- In Repeater-Builder@yahoogroups.com, Jacob Suter [EMAIL PROTECTED] wrote: I'm guessing that'd be the national weather service transmitter at 162 MHz. Close enough to look like FM broadcast, but the ridiculous power requirements aren't there. The NWS site north of me uses antennas that resemble slightly smaller FM transmitter 'loops'. FM commercial stations use very good antennas to save money on transmitters and electricity. The NWS has your tax dollars to spend! Of course, being that the NWS is only generally looking for 1-5kW EIRP, it may be cheaper to lease less tower space and throw on a slightly hotter transmitter.

Re: [Repeater-Builder] Cooling fan relay circuit?
The ELK-960 Delay Timer should fit rigth in, however no temperature sensing. http://www.elkproducts.com/products/elk-960.htm ---per LA9XKA At 05:05 17.05.2007, you wrote: My club has several ACC controllers and none have provided for cooling fan control. Does anyone have a simple circuit to turn on a fan with PTT and then keep it running for xx minutes after PTT is released? The repeater PTT line goes to ground on transmit. Most of the NE555 timer circuits that I have seen will not work in this configuration. Delay on drop out. DODO. Thanks de David K5RAV Yahoo! Groups Links

Re: [Repeater-Builder] VXR7000UD UHF, Fiplex Duplexers, ARR Receive Pre-Amp On Ebay
John, this can be done with the CE27 software from Vertex. Setting the frequency boundaries and rx tuning are described in the 'CE27 EEPROM Programmming Software Reference Manual - Supervisor Edition'. I assume You have got this from Vertex since You are an approved dealer for this equipement. regards, ---per At 02:32 16.12.2005, Maire-Radios wrote: being a Vertex dealer, at this time there is not a factory program available in the US that will let you program the VXR-7000UD into the 440 ham band.

RE: [Repeater-Builder] Vertex VXR-7000 battery backup
The problem here is twofold, we are not allowed to power our repeater from the site battery backup system unless there is a mains power failure so running the repeater of 12V is not an option. Secondly this battery bank is quite hefty, I am not sure that the repeater is able trickle charge the bank even if it is fully charged so this has to be the work of the backup system charger. That leaves me with the option of disabling the trickle charging from the repeater if I have been able to figure out how to do this. best regards, ---per At 02:43 29.03.2005, you wrote: I think the concern is that of many trickle charge systems. They are designed to float the batteries and switch over if needed. They are NOT designed to recharge a depleted battery bank. All this is fine unless you lose power on the site for 48 hours and run your batteries flat and then the power comes back on, and tries to charge them. Ideally if you ran on batteries for some time, you would go to the site and make sure they werent too low and/or charge them up with a real charger prior to putting the float charger back on them. Also you could put a low voltage dropout device in there that dropped the system prior to dipping the batteries too low. Good Luck!

Re: [Repeater-Builder] Sinclair Q2330E Tuning Problems
Eric, thank You for very accurate information, this is what I suspected. My harness is 323mm (~12.72 inches) between adjacent connectors so this is clearly a high-split duplexer. Do You (or anyone else) know where I could obtain a proper harness (Sinclar Canada/USA direct or a distributor)? 73, Per Molund LA9XKA At 03:27 08.01.2005, you wrote: If the distance between the centers of any two adjacent tee connectors is about 12.75 inches, you have the 148-174 MHz version. If the distance is close to 14 inches, you have the 132-150 MHz version. Both versions have the same physical dimensions and the same coupling loop assemblies; the harness is the only difference. The loops must be adjusted if the harness is changed. You cannot achieve the Sinclair specifications in the 2m band by simply re-tuning a high-split duplexer; you must use the longer harness, which can be purchased for about $120. Although rather heavy and somewhat cumbersome, the six-cavity Q2330E is an impressive performer when equipped with the proper harness and carefully tuned. 73, Eric Lemmon WB6FLY Yahoo!

[Repeater-Builder] Sinclair Q2330E tuning problems
I am trying to retune an Sinclair Q2330E duplex filter to 145 MHz (145.1375/145.7375) from it's factory configuration of 150 MHz (150.83/149.80), however the notch atenuation is strongly reduced. There is also impossible to set ut the proper bandpass/notch separation. I noticed fron the Q2330E specification sheet that the duplexer can be ordered for 132-150MHz og 148-174MHz, anyone know how I can determine which version I have on hand? I would assume the high frequency version can give this problem if I try to adjust it to 145 MHz? Can I assume the difference between the two versions are the cavity loops and the cable harness? best regards, ---per LA9XKA Yahoo!
