Radio Shack Amp

[xusmarine1979]

Hey all, anybody know how long a 9v battery should last in Radio Shack's signal amp? I found mine today and it makes a HUGE difference.
Thanks all.

Well the one I had, usually lasted about 20 hours before I had to switch batteries. I had the portable version, hope that helps.

Yes it does help, that's about the same for mine as well.
Thanks

I'm real happy with both of those amps. Im sorry there discontinuing the 3001 mod. They work great on Air freqs! Its a little too much on my home trunk sys.

I just can't believe how much of a difference it really makes. I have the portable one as well, it's on my Pro-96. For Cobra Commander, make sure you get at least one rechargeable 9v from Radio Shack, mine is always on.

Do ya'll pick up a lot of 8 interferences on 800 while using the amp?

Im not sure on what you mean on 8 interference, But I do get interference when I get into the center of town, the main reason for that is because of intermod. But to fix that I just hit the Attenuator. Clears out well.
I also use it on my Yeasu VX-7R since it has continues coverage ( 0-999 MHZ) it picks up everything. JUST DONT TRANSMIT WITH IT ON!

I try using the att as well with no luck. I think it's just the terrain around here.

The Att feature on my Pro-96 works beautifully. On rare occasions I did hear some buzzing even with the Att turned on when using the portable GRE Amp. I now use an amplifier that a buddy of mine gave me. He works for the cable company, & I believe it's a cable signal amp. In my opinion it works way better than the GRE amp, & best of all it was free! I don't hear no buzzing & the att works nice with it. Maybe cause it's not as powerful as the GRE version. I live in a busy County, with a lot going on all the time. I have the Amp hooked up to a Scantenna on my roof. The cable amp is only 13.5db, compared to the 20db of the GRE model. This one only works from 54-1000 MHz, & does a really nice job of picking up 800 MHz systems from a few cities over.

Interference wise I really can't think of anything that may be causing it. It's mainly only on the SO's system that I'm hearing it, but for some reason I can pick up the next county with no problem, but I have trouble picking up my own county.
