The battery will be in my shop. Although it's on the side that I don't heat often because it's storage. I've seen it go below freezing one year but besides that I think it doesn't go much lower than the 39º that I've seen. It's right next to a room that never goes below 60º and if I have to I can put it there and run cables through the wall. But I'd rather not.

Gonna be a LiFePO4 battery so that won't work for me, thanks for the link. I looked around for a relay but all I've found have a 40 amp rating on the NO contact and only 3 amps on the NC contact. Was planning on plugging the coil in and as long as there was power the relay would be closed cutting off the battery power through the contacts. And as soon as AC power died so would the relay connecting the battery to the repeater. 12-15 amps is what the repeater draws on transmit.

Do you have a suggestion for a regulator?

Only on a radio forum would you have guys asking what radio they used before they were "blowed up"

You mean like the US buying their computer chips from chyna and putting them in war equipment?

The DC-DC converter is essentially a voltage regulator +. Takes in 8-17v and outputs 10-15v. Has the advantage of boosting a lower voltage to required voltage. Main problem is the 14.4v charging the battery is way out of spec for the repeater. Most car regulators are 13.8v or more. Not usual to find something that puts out a true 12 volts these days.

They've claimed it was impeding an officers work or some crap like that. They gave out tickets around here years ago for flashing your lights to warn of speed traps.

Pretty sure the police will disagree with that. Maps got in trouble for ratting out their positions. Then it went to court I believe and they must have won because using my phone gps I get warnings for speed traps.

That's something I'm currently working on now. Not to worried about the home base station because I have a mobile in my truck. Plus I have a small solar system with a 3KW inverter to power 120v stuff. But the repeater needs backup and I haven't got that done yet. The repeater needs 12-13.2 volts so the battery along with the charger is too much for it so I need a DC-DC convertor or just build a relay system so when the power shuts off it automatically switches it to the battery. But I don't even have the battery or charger yet so as of now it's a moot point.

Exactly. But who wouldn't want to receive some warning that some traffic even is up the road? Guy sounds like he is unhappy and needs to may others feel the same.

What they don't tell them is the 72 virgins are other suicide bombers so they're all guys.

I think the only thing that might not be legal would be to give a police officers position to help others evade an operation such as a speed trap.

There's almost always someone on the air around here. They usually stay quiet until needed. I was trying to get a hold of my wife on a repeater I don't use much. Tried a few times and then went to another repeater channel and got her that way. But on the original channel someone broke in and told me he heard me fine. The base has a great connection to that repeater so it was weird my wife couldn't hear me. Got home to find out the PL had been changed somehow. So obviously she wouldn't be able to hear me.

I stole this.

Get a LiFePO4 battery for the base station to keep that up and running for a while. Or put solar on it and let it self charge to keep it up and running longer.

We just keep the radios on 24/7. In the shop it's hard to hear sometimes though. I gotta get an external speaker to blast out the sounds of my beckoning wife

That would be me I think.

I've used mine to replace text and phone to the wife. Now when I need to text her I have to search because she's been pushed down on the list. I'd like to get more of my family involved but they just don't want to because "they have a phone"

I put the black line in there to show the line of sight path. Who knows how it got there.

Was talking with a bunch of guys on this repeater tonight. The LI East End repeater on 575 The tropospheric ducting was phenomenal tonight. I wasn't talking to them on my base station with my antenna 40' in the air. I was talking to them on my TD-H3 HT pushing about 4 watts because the battery is about 2/3rds full. The guys were telling me I was coming in 5x5, frik'n amazing. I first noticed that I kept getting interference on my HT in the living room on the 575 in Holyoke. Then I recognized the double tone beep the repeater has as a courtesy beep. So I went outside and called for a radio check announcing I was in Connecticut up north. Was able to talk with several people for over 20 minutes. We could have continued but it was after midnight plus I wanted to check on the base. Still 5x5 down there, but it was coming in better on the HT than the base, weird. Had to tell my little story. Not many times you get to talk 70+ miles on an HT with a repeater that has a mountain in the way.

Man. If I was a mod here, this thread would be shut down by now.

So you use the $100 billion dollar system to tell people you want to use the couple thousand dollar system....

I went through all the calculations of loss and gain for my system and it is what it is. I have a Wouxun XSKG20+ that puts out 25 watts. I screwed up. I'm using the Hyperflex 13 not the 10. So 1.7dB loss plus 4 fittings, lightning arrester. Antenna is 7.2dBi gain so 5.05dBd gain. Comes out to just about 50 watts ERP out of the antenna with 15.7 watts making it to the antenna. 10xLOG10(50/15.7)=5.03dB gain on antenna. I'd call that close to 5.05dBd after you subtract 2.15 from 7.2 to convert from dBi to dBd.

They'll start talking when SHTF and other forms of communication have disappeared.
