Re: [Repeater-Builder] Weather Radios
When I was playing with SAME weather radios a couple of years back, I called the local NWS weather office and found out what time they were going to conduct their test. I then set up a timer on a cassette recorder to record the broadcast. I guess you could use this as the audio source for a service monitor, but what I did was just inject the audio into the weather radio at the volume control. In my case I wasn't going to use the RF section of the weather radio as it got clobbered by all the RF on the hill I was on. I think I used a GE Phoenix as the receiver, and then coupled the audio to the weather radio so I could use it's SAME detector. I just injected the audio where I was going to inject the receive audio. It worked just fine.

Re: [Repeater-Builder] Weather Radios
I also think that NWS performs weekly tests of SAME transmissions on Wednesdays between and 11-1PM. Check with NWS in your area and you may not have to wait until the next storm.

Re: [Repeater-Builder] Re: 2 Delta S's as a UHF repeater
You can use an S or SX for the transmitter, but the receiver definitely needs to be the S. The helicals in the S make the difference. I think the S has about 2-3 MHz of bandwidth on receive, while the SX has close to 20 MHz. I have also used GE Phoenix S UHF radios for a repeater as well. Picked up a couple of narrowband units a while ago for $10 each. As longs as I keep the power down, seems to work pretty well. Any other questions, feel free to ask.

Re: [Repeater-Builder] 2 Delta S's as a UHF repeater
I have done this on both 2 meters and 70cm with no problems. In fact, if you set the radios up identically, you can 'flip' them if either a transmitter or receiver fails.

Re: [Repeater-Builder] Re: WTB 440 Mhz Receiver with COR
If you put a diode in the COR line with the cathode toward the tap point, doesn't this raise the voltage? I think the voltage on the anode would be 0.5 plus the diode drop- Jim, KC1RM - Original Message - From: "Al Wolfe" <[EMAIL PROTECTED]> To: Sent: Tuesday, March 30, 2004 5:51 PM Subject: [Repeater-Builder] Re: WTB 440 Mhz Receiver with COR > Mathew, > Maybe all you need to do is stick a small diode in your COR line.

FYI, this is not a project for the faint at heart- I performed this mod on my Ranger pickup. The only way to gain access to the sending unit was to remove the box and access the tank from the top. The newer Fords use nylon gas line with somewhat delicate fittings. If you break one of the fittings, it is not an easy task to replace.
