[Repeater-Builder] 30A power supply suggestion
Hi all and Happy New Year! I'm looking for a power supply for our local repeater. We are currently using a cheap 20A power supply, but I'm worried it may fail under heavy usage and feed our equipment with higher voltage (it happened in the past with a similar power supply which supplied 35V instead of 13.8) What I want is a reliable 13,8V, 30A power supply that can provide at least 15A at 100% duty cycle. It also needs to be light (i.e. switching, not transformer type), so that I won't have to pay a fortune to have it shipped here. Any suggestions on models or online shops I can order from? cheers, Andreas - 5B8AP
Re: [Repeater-Builder] 30A power supply suggestion
Duracomm LP-25. Unless lightening hits it, it will work. Very reliable. We have many in service. No. Failures to date except direct lightening strike. - Original Message - From: Repeater-Builder@yahoogroups.com Repeater-Builder@yahoogroups.com To: Repeater-Builder@yahoogroups.com Repeater-Builder@yahoogroups.com Sent: Wed Jan 07 10:38:51 2009 Subject: [Repeater-Builder] 30A power supply suggestion Hi all and Happy New Year!

[Repeater-Builder] CAT300DX Programming
I'm in the process of programming up a new controller on my repeater (CAT300DX) and I think I've got everything setup the way I want it except for the courtesy tone. I was just wondering what others were using as the courtesy tone on their CAT300s. Any DTMF stings to play with and get ideas from would be appreciated. If anyone has any hints/tips/tricks/cool ideas of things to program into the controller I'd appreciate hearing them as well. Lastly, if anyone has a copy of the CAT300DX programming software (ED-300W) they'd be willing to loan out you would be my hero. Thanks. Alex
Re: [Repeater-Builder] 30A power supply suggestion
I like switching supplies... which likely makes me in the minority. I've used several Duracomm, Astron, Samlex, and cannibalized computer- grade supplies. The only ones that have caused me problems have been the Astrons. I'm only a little over a year into using a Samlex 35A switcher on a TPL-PA6-1AE-RXRF. The repeater has been up for over an hour solid many times, but isn't what I'd call highly used. So far no complaints (so far). On Jan 7, 2009, at 1:10 PM, NORM KNAPP wrote: Duracomm LP-25.

[Repeater-Builder] Tower Identification
How can I identify an otherwise unknown tower as Rohn 20, 25, 45, etc. or even another tower manufacturer altogether? I'm printing off the Rohn 25, 45, and 55 section details, but beyond those drawings, I've no other clues to ID the tower. -- Kris Kirby, KE4AHR k...@catonic.us But remember, with no superpowers comes no responsibility. --rly

Re: [Repeater-Builder] CAT300DX Programming
Alex, I operated a CAT300 with a two tone rising bubble up for about 15 years before linking that controller to another repeater last year. At that time I changed the CAT300 courtesy beep to a chime since I was getting a two tone DTMF courtesy beep through the link, indicating that the repeaters are linked. A local user on the CAT300 repeater hears the two tone DTMF plus chime as long as the repeaters are linked, and hears only the chime if the repeaters have been disconnected. Details of the operation and combining the CAT300 with the RLS1000 are contained in the forum: http://sbarcnm.org/forum/index.php?board=3.0 A lot more info there than you need, but it explains how I used the courtesy beep as telemetry to show the state of the system - linked or unlinked. 73 - Jim W5ZIT --- On Wed, 1/7/09, Alexander N Tubonjic kg4...@yahoo.com wrote: From: Alexander N Tubonjic kg4...@yahoo.com Subject: [Repeater-Builder] CAT300DX Programming To: Repeater-Builder@yahoogroups.com Date: Wednesday, January 7, 2009, 2:05 PM I'm in the process of programming up a new controller on my repeater (CAT300DX) and I think I've got everything setup the way I want it except for the courtesy tone.

RE: [Repeater-Builder] 30A power supply suggestion
Andreas, I've had no problems at all with any of the following switch-mode power supplies: DuraComm LP-25, 22 amperes continuous, 25 amperes short-term, about US$ 122 Samlex SEC1223, 23 amperes continuous, 25 amperes short-term, about US$ 106 Astron SS-30, 25 amperes continuous, 30 amperes short-term, about US$ 114 The above power supplies can be purchased through commercial communications supply houses, such as Tessco, Talley, and Hutton. The Samlex and Astron power supplies are also available through Amateur Radio suppliers, such as AES and HRO. Despite some uninformed claims to the contrary, the above switch-mode power supplies do not generate interference with nearby radio systems- which is why they are recommended by the majority of commercial radio manufacturers. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Andreas Papagapiou Sent: Wednesday, January 07, 2009 8:39 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] 30A power supply suggestion Hi all and Happy New Year!
