RE: [Repeater-Builder] Re: Folded Diploles or Vertical antenna?
I'd change out the LMR cable for something that will not cause you possible problems later on. You've spent good money for a fine system so far, don't jeopardize its operation by going cheap and using LMR for the feedline. The overall best suggestion is to use at least 1/2 hardline for this application, especially since you have a short run. (Longer runs woujld be better with 7/8 or larger...) Do *NOT* use LMR anywhere, even for your jumpers... If you're not familiar with the issues surrounding LMR cable, search the message database at this group - you'll find discussions ad nauseum regarding the use of LMR and its being prone to noise when used in duplex (repeater) operation.

Re: [Repeater-Builder] Re: Simulating a weather alert
Joe, I don't think you can block the weekly test unless it is sent as what one might call a test to all SAME code message. There is a SAME code, think ending in 999 in the county part of the message that will go to all if that is programmed in. I am sure the NWS sends test messages to all the counties within that NWS office area being served. In the SAME encoding is the format iding it as a test message rather than say a tornado, warning, etc. If you have more detailed receiver that lets you determine not only the county to alert, but the type of message to respond to then you could mask out the test message. I think most all less expensive receivers do not have this feature although they display warning, watch and statement. If you got a county in the receiver then the test message will be sent to that county. This is part of the test...to test your receiver to make sure you have the county of choice(s) programmed and your receiver is working. I have about 5 counties programmed in my receivers, but get only one test message. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.

RE: [Repeater-Builder] Re: Simulating a weather alert
Randy, I think this 1k tone is for the older receiver signaling. The alert message turn on the SAME and also old receivers that react to any alert from NWS. This unit you have you indicate it is for transmitting the SAME messaging. Is this one of the broadcast station type encoders allowing you to transmit messages to SAME receivers??? The gov did set up so broadcast stations could act as the alert stations. The stations took on a responsibility that required them to act if an alert was sent.

Re: [Repeater-Builder] Re: Simulating a weather alert
Ron and all; I wouldn't call it 'don't want the responsibility' so much as 'stretched so thin with limited personnel running multiple stations that it's not possible'. When we end up with 2-3 people running a 'cluster 'of anywhere from 4-7 stations, there simply is not enough time between recording commercials, entering new music into the systems, cutting 'voice tracks', answering the phone, and so on; to deal with what can become a very time-consuming problem. Most broadcasters that I know, especially those of us that started out back in the late 60's-early 70's, remember how important it was to our listeners to get emergency information on the air as quickly as possible back in 'the old days'. Most stations had a 'Weather Plan', stationing personnel in spots to look for approaching storms, and reporting back by land-line phone or Remote Pick-up frequencies. These days, Big Corporate Radio has consolidated studios and cut personnel to where that kind of committment is no longer possible. So we end up re-broadcasting what the NWS sends us and hope it is good enough. Just my $ 0.02, feel free to fire away.

Wait, you said decoder on and off, and then said encoder... I want to be able to toggle the decode function on and off. In other words select ctcss control or cor control. The encode will be on all the time. It will be optional for users to have ctcss on or off. It would be an advantage in down town areas.

Hi Garry, Yeah I worked in radio for a while myself as a broadcaster. It’s quite a shame that it isn’t like the good ol days when it comes to weather. You depend on the NWS and you might get a chance to say a few things. Thankfully, my experience was at a small station so we had mor liberation when it came to this if we thought it was important enough we could pull the satellite link and anoounce what we had too. This was about 8 years ago. I am not even sure the station still runs and if it does did it go to a big conglomerate now.

When we end up with 2-3 people running a 'cluster 'of anywhere from 4-7 stations, there simply is not enough time between recording commercials, entering new music into the systems, cutting 'voice tracks', answering the phone, and so on; to deal with what can become a very time-consuming problem. Most broadcasters that I know, especially those of us that started out back in the late 60's-early 70's, remember how important it was to our listeners to get emergency information on the air as quickly as possible back in 'the old days'. Most stations had a 'Weather Plan', stationing personnel in spots to look for approaching storms, and reporting back by land-line phone or Remote Pick-up frequencies. These days, Big Corporate Radio has consolidated studios and cut personnel to where that kind of committment is no longer possible. So we end up re-broadcasting what the NWS sends us and hope it is good enough. Just my $ 0.02, feel free to fire away.

The alert message turn on the SAME and also old receivers that react to any alert from NWS. This unit you have you indicate it is for transmitting the SAME messaging. Is this one of the broadcast station type encoders allowing you to transmit messages to SAME receivers??? The gov did set up so broadcast stations could act as the alert stations. The stations took on a responsibility that required them to act if an alert was sent. Most stations do not want this responsibility. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.

We use a receiver that is programmable for up to 4 counties and individual selection of the EAS event(s).

[Repeater-Builder] Re: Simulating a weather alert
It was made by MTS. However after checking their web site, all I find is the weather radio and not the test unit.

This is the first I have heard of a commercial made unit for testing. Thanks JIM KA2AJH
[Repeater-Builder] Re: Simulating a weather alert
The test unit I have actually transmits the SAME data burst, then a 1K tone where the wx bureau voice would be. Then it transmits another data burst to close the receiver speaker.

Anyone have a service manual or schematic for this unit that they wouldn't mind scanning in or faxing? Or, does anyone know what company purchased their assets? 25 in, 100 out, UHF, no fan. Thanks. Tony
RE: [Repeater-Builder] Re: noise on exposed folded dipole arrays and fiberglass encased antennas - YES
Thanks Bob Reducing power was no measured help till I got to minimal watts and unfortunately there are no extra VHF band antennas to try (unless I borrow one from the GOV or the TX highway patrol or state park folks) I guess I won't try those feed lines/antennas.

I have a current situation at 580 ft. I m diagnosing. Enough to get into another antenna ~30 ft. away. After the lightning strike we had severe desense (over 30 dB) so we tried to run split antennas with the 4-pole on TX GP9 on RX. Still had several dB of desense until we reversed the antenna connections. Station works fine into a dummy load tested with a sampler slug and no desense. Add the feedline and antenna and I get 15db degradation. I have looked at the freqs the ant is hearing and don t see an IMD issue. Spectrum looks normal. The problem is a steady 15 db. I think it s the db antenna. We re 20ft from the top of the tower. Any suggestions before we pay a climber? Try reducing the TX power see if there's some threshold power level where the desense suddenly appears. That would likely indicate something arcing somewhere. The problem could be in the feedline, your antenna or an antenna mounted close to yours. In situations like this a spare antenna of some sort really comes in handy, even if it's relatively low on the tower. You could then continue to RX off the defective antenna TX on the low spare antenna. Bob NO6B
