I have a used Whelen edge with 8 strobe heads, 4 halogens, alleys, and the pierce alert -to install on a new brush truck. It came off an old police car our city had. Nobody took the time to mark anything when it was removed and I don't want to trash the power supplies. I have been to Whelen''s web s...

"...but I still need to figure out why Georgia State Patrol is set up this way! They use half-duplex car-base and base-car, although I think they do use one frequency of the pair for car-car. Also, they use the same half-duplex pair throughout the whole state!" The New York State Police h...

Suddenly all of my buttons except mode up died on my uhf m1225 20ch. It also will not transmit anymore? Yikes!

Here's the situation. We have a chance to get on a 250' tower for free. (fire-ems) Now the problem. We can only put up one antenna but we operate a uhf msr2000 and vhf msr2000. We are tossing around the idea of using a dualband duplexer and dualband antenna. My first thought is that this is cheesy t...

Larson makes a 1/4 wave flexible whip available from tessco...I have one on my MT1000 for rural firefighting...It is an improvement over the factory duck but you look like a dork carrying it.

To everyone: Why do you think all of these agencies leaving lowband? Like I said in the origial post, the local troopers say their lowband doesn't work so ISP gave them cell phones! I can see larger metro areas going 800 but majority of posts in Indiana only have 5-6 cars on patrol per shift. Person...

I'm sorry, I should have given alittle more info....Most trucks use 1/4 whip, ball-spring..some roofmount maxrad baseloads all tuned. Our repeater antenna, feedline (1/2") duplexer(no desense) all less than 2yrs old. Simplex coverage doesn't impress me either compared to 150Mhz especially with ...

Just curious what everyone thinks about lowband? good or bad?I work for a rural eletric co-op that operates a repeater on 47Mhz.(110W @230ft) Most of the mobiles are 110W maratracs and some micors. Our coverage seems to lack and the repeater is noisiy in places where it shouldn't be.(10 air miles) M...

I completely understand what you are talking about. I have 2 MT1000's that do the same thing while on PL. I have always wondered if it has to do with the squelch setting. If I remember correctly, there are independent settings for carrier, PL, and scan in RSS?

Its purpose is to close the audio path before the carrier drops. It does this by reversing the phase of the PL signal....

I have high-band maratrac the unsquelches randomly. Temp has nothing to do with it. Sometimes you can turn it off and on rapidly and it will squelch. The internal adjustment won't squlch when it decides to do this...it's not the vehicle either.

SD70MAC.....railroader?

I am a lineman for a rural electric co-op and we have a low-band repeater. We have the same problem but all of our employees are aware of what causes it and we deal with it. Everyone understands talkaround. Our office control station runs 110 watts (for some reason?) with a 3 element yagi to talk to...
